Audi RS3 Sportback, 2012

Power from the 2.5 TFSI is transmitted to the road via a seven-speed S tronic and quattro permanent all-wheel drive. 19-inch wheels and fenders made of carbon-fiber-reinforced plastic (CFRP) underscore the Audi RS3 Sportback's position of distinction.

Dynamic par excellence: the drivetrain and suspension
A seven-speed S tronic comes standard in the Audi RS3 Sportback. The compact dual-clutch transmission shifts gears almost imperceptibly, with extreme speed and comfort. Seventh gear is very tall - a measure that reduces fuel consumption. In addition to two automatic programs, a manual mode is available, which can be controlled with optional paddles on the steering wheel. The launch control system manages maximum acceleration from a standing start.

The Audi RS3 Sportback has 19-inch wheels. The front tires are size 235/35, whereas the tires at the rear are 10 millimeters (0.39 in) narrower to further enhance handling. The internally ventilated brake disks measure 370 millimeters (14.57 in) in diameter at the front and 310 millimeters (12.20 in) at the rear. The front friction rings are perforated.
They are connected by hollow pins to the aluminum brake disk covers and gripped by four-piston fixed calipers painted in black. The electronic stabilization program (ESP) has a sport mode and can be switched off partially or entirely.
The Audi RS3 Sportback hints at its enormous potential from the very first glimpse. Its front and rear aprons have been prominently modified, and a large roof spoiler sits atop the rear end. The flared front fenders are made of carbon-fiber-reinforced plastic (CFRP) - an expression of Audi expertise in lightweight design.

The dynamic style is matched in the interior, entirely black and sporting a number of RS3 logos. Sport seats with Fine Nappa leather upholstery are standard; the inlays sport a Piano finish. A boost pressure indicator, an oil thermometer and the lap timer are all included in the driver information system. The instruments and the selector lever are specially designed.

.
The Audi RS3 Sportback is 4.30 meters (14.11 ft) long, 1.79 meters (5.87 ft) wide, and 1.40 (4.59) meters high. It achieves a drag coefficient of cd 0.36 and has a frontal area of 2.16 sq m (23.25 sq ft). Its curb weight is 1,575 kilograms (3,472.28 lb). In its normal configuration, the luggage compartment has a capacity of 302 liters (10.67 cubic ft), but with the rear seatbacks folded down, it holds an impressive 1,032 liters (36.44 cubic ft). As options Audi also offers practical components, including a luggage compartment package and a load-through hatch with or without a ski bag.

Interior
A distinctive interior design with sporty circular air nozzles, perfect ergonomics and a no-holds-barred approach to quality in the selection and use of materials - these are all typical traits of the Audi A3 model line. In addition to these, the Audi RS3 Sportback comes with a host of special features.
The entire passenger compartment, including the roof lining, is a study in black. Inlays in Piano finish black are standard. Alternatively, the new Aluminium Race material and a selection of classy woods from the customization range are available as exclusive options. Silver piping borders the floor mats. The door sills, the tachometer, the seats, the steering wheel and the selector level for the seven-speed S tronic all feature RS3 badges. The pedals gleam with an aluminum finish.

The sport seats with prominent side bolsters provide excellent support for the body. They are upholstered in Fine Nappa leather with silver contrasting stitching. Featuring a heavily contoured rim, the triple-spoke leather multifunction sport steering wheel is flat-bottomed and wrapped in perforated leather complete with contrasting stitching. The shift paddles have a matt aluminum look.

Engine
For decades, gasoline engines with turbocharging technology have been the domain of Audi - the five-cylinder TFSI in the Audi RS3 Sportback carries on the tradition of high-performance engines. From 2,480 cc of displacement, it draws 250 kW (340 hp) of power, which is available between 5,400 rpm and 6,500 rpm. Its specific output is 100.8 kW (137.1 hp) per liter of displacement. The maximum torque is 450 Nm (331.90 lb-ft) - it is readily available at the low end of the rev range, around 1,600 rpm, and remains constant up to 5,300 revolutions.

The strengths of the five-cylinder engine, which celebrated its debut in the TT RS in 2009, have impressed expert audiences. Last year, a jury of 71 international journalists named the 2.5 TFSI "Engine of the Year" in the 2.0 to 2.5-liter category, giving Audi its sixth consecutive category win in the competition. In the five previous years, the 2.0 TFSI had taken the award.

The 2.5-liter engine is ultra-compact. Just 494 millimeters (19.45 in) in length, the long-stroke unit (bore x stroke 82.5 x 92.8 millimeters (3.25 x 3.65 in) is ideally suited for transverse installation. Its features an 88-millimeter (3.46-in) spacing between cylinders, and of the six crankshaft main bearings, the ones on the outside have been offset slightly toward the inside. The engine's weight of 183 kilograms (403.45 lb) also sets a record. It keeps the Audi RS3 Sportback's total weight in check and pays off big in terms of axle-load distribution and, ultimately, handling.

The pistons in the 2.5 TFSI are made of cast aluminum with a heat-resistant alloy. Each weighs only 492 grams (17.35 oz), including the rings and pins. The pistons are designed for maximum loading. Tiny, perfectly arranged asymmetries on the barrels and slightly sloped skirt walls further increase their strength. The connecting rods are forged components. Sodium-cooled exhaust valves and hardened valve seat inserts are located inside the cylinder head, which is cast from an aluminum alloy.

Blazing acceleration: 0 - 100 km/h (62.14 mph) in 4.6 seconds
The Audi RS3 Sportback accelerates from a standing stop to 100 km/h (62.14 mph) in 4.6 seconds - faster than any competitor in the compact category. Its superb pulling power allows it to pass other cars without the slightest effort. Top speed electronically is limited to 250 km/h (155.34 mph). Underneath the hood lies the engine with its red cylinder-head cover exposed - a fascinating piece of technology and a treat for the eyes.

In terms of fuel consumption, the powerful five-cylinder engine is frugal, using on average just 9.1 liters of fuel per 100 km (25.85 US mpg) and emitting 212 g CO2 per km (341.18 g/mile). This efficiency, which puts the Audi RS3 Sportback clearly ahead of its main competitors, can be attributed to the combination of FSI direct injection and turbocharging, two core competencies of the brand with the four rings. In motorsport, the toughest test laboratory in the world, TFSI technology has powered the Audi R8 to five final wins in the 24 Hours of Le Mans.
The injection system in the 2.5 TFSI is state-of-the-art. In a highly precise measuring method, the pressure sensor in the intake manifold performs load sensing for the control unit. Five individual flaps, which are actuated by negative pressure, mix the incoming air in a calculated configuration in the combustion chamber.

The common-rail system injects fuel into this tumble at pressures of up to 120 bar. The fuel swirls intensely in the combustion chamber, which in turn cools the walls. This solves an old problem with turbo technology - the tendency toward early spontaneous ignition of the mixture at hot spots in the combustion chamber. This "knocking" combustion is brought about by strong heat build-up at high compression. The cooling effect of the direct injection facilitates a high compression ratio of 10 : 1 along with a correspondingly high efficiency ratio.
The two camshafts in the head of the five-cylinder unit also enhance the efficiency of the filling. Each one is adjustable by 42 degrees of crankshaft rotation. They are driven by a two-stage chain drive consisting of an extremely quiet inverted tooth chain, a roller chain and an idler gear.

Turbo throughput: 335 liters (11.83 cubic ft) of air per second
The large turbocharger is generously sized, with a compressor wheel that measures 64 millimeters (2.52 in) in diameter at the outlet. At full load, the charger is able to compress up to 335 liters (11.83 cubic ft) of air and generates boost pressures of up to 1.2 bar. Its housing has a separate oil supply, and a dedicated water pump provides cooling. The intercooler lowers the temperature of the compressed air at full load, thereby achieving an efficiency of over 80 percent. Much effort has gone into optimizing the entire intake path to minimize pressure loss.

Drivetrain
Audi delivers the Audi RS3 Sportback with the seven-speed S tronic as standard. The high-tech gearbox transmits power via three shafts: one drive shaft and two output shafts. This layout results in a short construction - a prerequisite for interaction with the transversely mounted engine.
Like all dual-clutch transmissions, the seven-speed S tronic in the Audi RS3 Sportback comprises two transmission structures. The shifting process takes place in hundredths of a second as the clutches switch. Shifts are fluid and extremely smooth, with no perceptible interruption of traction.

Porsche 911 GT3 R Hybrid, 2011

 

 

Porsche 911 GT3 R Hybrid, 2011

After its debut in Switzerland, the Porsche 911 GT3 R Hybrid tested in long-distance races around the Nürburgring, Germany. The highlight of this test programme  be the 24 Hours race around the 14-mile Nürburgring Nordschleife circuit on 15/16 May 2010. However, the focus is not on the Porsche 911 GT3 R Hybrid winning the race but rather serving as a spearhead for the technology and a 'racing laboratory' that will provide invaluable knowledge and insight on the subsequent use of hybrid technology in road-going Porsche sports cars.
110 years since Ferdinand Porsche - the company's founder - developed the world's first car with hybrid drive, the Lohner Porsche Semper Vivus, it is entirely appropriate that Porsche is once again employing this visionary drive concept in a production car-based GT racing programme.

The hybrid technology featured in the Porsche 911 GT3 R Hybrid has been developed especially for racing, and is set apart from conventional hybrid systems in its configuration and choice of components. Uniquely, an electrical front axle drive with two electric motors each developing 60 kW supplements the familiar 480 hp (353 kW) four-litre flat-six 'boxer' petrol engine at the rear of the Porsche 911 GT3 R Hybrid. Consequently, the Porsche 911 GT3 R Hybrid has four driven wheels, offering even greater traction and agility.

A further significant point is that instead of the usual batteries of a conventional hybrid-powered road car, this 911 features an electric flywheel power generator - mounted inside the cockpit beside the driver - that delivers energy to the electric motors on the front axle.
The flywheel generator itself is an electric motor - with its rotor capable of spinning at speeds of up to 40,000 rpm - and stores energy mechanically as rotation, or kinetic, energy. The flywheel generator is charged-up whenever the driver applies the brakes, with the two electric motors reversing their function on the front axle and acting themselves as generators.

The driver is able to call upon this extra energy from the charged flywheel generator at his command for competitive advantage, such as when accelerating out of a bend or overtaking. The flywheel generator is slowed down electromagnetically in the generator mode and able to supply up to 120 kW to the two electric motors at the front axle from its resource of kinetic energy.

The energy formerly converted into heat, and thus wasted, upon every application of the brakes is now converted highly efficiently into additional drive power.
Depending on racing conditions, hybrid drive is used in this case not only for extra power, but also to save fuel. This again increases the efficiency and, accordingly, the performance of the Porsche 911 GT3 R Hybrid, by reducing the weight of the fuel tank or making pit stops less frequent, for example.

Porsche Intelligent Performance
The Porsche 911 GT3 R Hybrid is a perfect example of the Porsche Intelligent Performance philosophy, a principle to be found in every Porsche and defined as more power on less fuel, more efficiency and lower CO2 emissions - on the race track and on the road. Already, customers can buy a Porsche 911 coupe with a six-cylinder 345 bhp engine which can return nearly 30mpg Combined and produces just 225 g/km CO2; a feat unrivalled in its performance class and just one example of the application of Porsche Intelligent Performance to maintain outstanding driving dynamics yet lower running costs and environmental impact.

Devising smart, individual engineering solutions to combine performance and efficiency with everyday usability is something for which Porsche is renowned, and is evident in such developments as lightweight body construction methods, Porsche Ceramic Composite Brakes (PCCB) and the Porsche Doppelkupplungsgetreibe (PDK) double-clutch gearbox.

Mercedes SLS AMG Roadster, 2012

 

 

 

 

 

 

 

 

 

 

Mercedes SLS AMG Roadster, 2012

The technological highlights of the 2012 SLS AMG Roadster  an aluminum spaceframe body, an AMG 6.3-liter V8 front-mid engine with dry sump lubrication developing a peak output of 563 hp and 479 pound-feet of torque, a seven-speed dual clutch transaxle transmission and a sports suspension with aluminum double wishbones - all of which will raise the pulse of sports car enthusiasts while providing outstanding driving dynamics and driving pleasure.

The compact fabric soft top of the Mercedes-Benz SLS AMG Roadster opens and closes in just eleven seconds, and can be operated on the move at speeds up to 31 mph (50 km/h). The new Adaptive AMG Sport Suspension with electronically controlled damping is available as an attractive optional extra. It enables the damping characteristics to be modified at the touch of a button. Using the AMG DRIVE UNIT, the driver of the SLS AMG Roadster is therefore able to choose his own suspension setup. Three modes are available: "Comfort", "Sport" and "Sport plus".
"AMG Performance Media" is a unique new feature: the innovative, motorsport-inspired multimedia system offers an unrivalled combination of numerous telemetric displays such as lateral and linear acceleration, various engine data and lap times on a racetrack.

Pure roadster design with perfect proportions
The new Roadster adds a second exciting dream-car to the SLS AMG family. Head of Design at Mercedes-Benz, Gorden Wagener: "As in the gullwing model, the pure, athletic design immediately catches the eye. Whether with the roof open or closed, the Mercedes-Benz SLS AMG Roadster is an impressive visual delight!" The perfect proportions are particularly memorable: a long hood, the greenhouse positioned well to the rear and a short rear end. Plus the automatically extending rear wing, long wheelbase, wide track and short overhangs - in short, the convertible SLS AMG exudes effortless performance and an authentic charisma. The pronounced shoulder sections are reminiscent of tensed muscles, and suggest sheer power in combination with the large wheels - 265/35 ZR 19 (front) and 295/30 ZR 20 (rear). The attractive AMG Sepang brown metallic paint finish and weight-optimized forged wheels in a 10-spoke design, painted in matte black with a high-sheen rim flange, are available as new optional extras.

Features reminiscent of the 300 SL Roadster, the classic dream-car from the 1950s, include not only the wide radiator grille with its large Mercedes star and the wing-shaped cross-fin, but also the fins on the hood and on the vehicle sides. Like the Mercedes-Benz SLS AMG Roadster, the 300 SL Roadster appeared slightly later than the original gullwing 300 SL, but unlike the SL's both AMG dream cars are available at the same time.
Interior atmosphere like an aircraft cockpit

The interior continues the breathtaking design idiom of the exterior, and awakens associations with an aircraft cockpit: prominent features include the dashboard in the shape of a wing and the air vents with adjustable, cruciform nozzles reminiscent of jet engines. The extended center console of matte, solid metal and the new E-SELECT lever in the shape of an aircraft's thrust control are also design features adopted from the world of aviation. Another discreet, fine detail is the embossed AMG emblem on the leather-lined selector lever.

The AMG DRIVE UNIT - which like numerous other interior features is available in genuine carbon-fiber - is the central control unit in the center console: it allows the driver to choose a personal vehicle setup, including adjustment of the optional Adaptive AMG Sport Suspension. The AMG Performance steering wheel with its high-grade premium leather lining and flattened bottom rim section provides perfect vehicle control. The shift paddles and lower steering wheel bezel are made of solid metal.

Fully automatic, weight-optimized soft top
The sensual experience in the 2012MY SLS AMG Roadster is further enhanced when the soft top is open, and the powerful, naturally aspirated eight-cylinder engine with 563 hp and 479 pound-feet of torque asserts itself and makes the heart beat faster with its distinctive AMG eight-cylinder sound. The fabric soft top can be opened and closed while on the move at speeds up to 31 mph (50 km/h); the fully automatic opening/closing process takes only eleven seconds. The driver only needs to operate the roof control unit conveniently integrated at the front of the center armrest. When open, the soft top is space-savingly retracted behind the seats in a folded Z-configuration. Three soft top colors - black, red and beige - are available to suit the nine exterior and eight interior colors.

The three-layered fabric soft top is a weight-optimized magnesium/steel/aluminum construction, and contributes greatly to the car's low center of gravity. The soft top has a seamlessly bonded rear window of heated singlelayer safety glass. The flush, gap-free transition between the outer roof skin and the rear window keeps wind noise low. A continuous, flexible water pocket running under the soft top catches rainwater and directs it to the underbody via two apertures on each side. The trunk capacity is 6.1 cubic feet with the roof either open or closed, and therefore roughly equal to that of the SLS AMG Coupé (6.2 cubic feet).

Outstanding material quality and finish
The finest leather, matte-finished solid metal or optional, genuine carbon-fiber trim create an exclusive ambience and correspond with the authentic feel of the cockpit. Precisely executed decorative and contrasting stitching enhances the visual impression, heightens the hand-crafted look and reflects the attention to detail which is the hallmark of Mercedes design.
The standard appointments of the Mercedes-Benz SLS AMG Roadster include black designo leather, heated AMG sports seats, a detachable glass windstop, COMAND with Navigation and DVD player, anti-theft alarm system with tow-away protection and interior monitoring, dual-zone automatic climate control and the KEYLESSGO starting function. The standard AIRSCARF system exclusive to Mercedes-Benz acts like an invisible scarf warming the head and neck areas of the occupants. It is integrated into the backrests of the AMG sports seats, and blows warm air from vents in the head restraints. The airflow can be adapted for different occupant sizes by means of adjustable louvers, and the level of warmth can be selected in three stages at the touch of a button.

Leather-lined roll-over bars with integrated mesh in a "Silver Shadow" look are available in conjunction with designo Exclusive leather to reduce turbulence in the cockpit. Ambient lighting is integrated into the electrically folding exterior mirrors.
Single-tone or two-tone designo leather in espresso brown is available as a new interior color - this dark shade of brown perfectly matches the new metallic paint finish AMG Sepang brown.

AMG Performance Media and Bang & Olufsen as optional highlights
In addition to the Bang & Olufsen BeoSound AMG surround sound system, another optional entertainment highlight is the AMG Performance Media. In an unprecedented way, this racing-inspired system combines numerous telemetric displays such as engine data, lateral and linear acceleration and lap times on a racetrack. AMG Performance Media is activated by pressing the AMG key in the AMG DRIVE UNIT, and operated using the COMAND Controller. Key functions:

• Real-time display of engine oil, coolant and transmission fluid temperature
• Real-time display of engine output, torque and accelerator position
• Real-time display of individual tire pressures
• Real-time display of acceleration time from 0-60 mph or 0-100 km/h (alternatively: quarter-mile)
• Real-time display of lateral and linear acceleration combined with braking performance and accelerator position, including memory function
• Recording of individual lap times on a closed racetrack, with sector times and memory function
• Integration of DRIVE UNIT functions to save setup data to memory and initiate RACE START

The different functions of AMG Performance Media are shown by the color display integrated into the dashboard. Three displays are shown at any one time, with the most important information positioned in the center. Digitally simulated dial instruments with red needles ensure outstanding legibility.

Specifically reinforced aluminum spaceframe, low curb weight
In addition to maximum comfort, the key factor for driving pleasure in the new SLS AMG Roadster is the outstanding performance. The basis for this is the innovative body design: the chassis and body are made of aluminum, a design combining intelligent lightweight construction with high strength. With a curb weight of 3,661 pounds (estimated), the Roadster is only 88 pounds heavier than the Coupé. The result is a remarkable power-to-weight ratio of 6.5 pounds per hp.

To achieve the same level of driving dynamics - without a fixed roof, the Mercedes-Benz SLS AMG Roadster incorporates several features specifically designed to strengthen the bodyshell, including side skirts with greater wall thicknesses and additional chambers. The dashboard cross-member is supported against the windshield frame and center tunnel by additional struts, and a curved strut between the soft top and the tank reinforces the rear axle. The lack of a roof and gullwing doors means that the open-top SLS AMG has a reinforcing crossmember behind the seats to support the fixed roll-over protection system. This also accommodates the 250 watt subwoofer of the Bang & Olufsen BeoSound AMG high-end sound system.

All this prevents unwanted vibrations right from the start, and makes it unnecessary to use the additional, weight-increasing vibration dampers that are often found in open-top sports cars. The weight-optimized aluminum spaceframe weighs 536 pounds, tipping the scales at just 4.5 pounds more than the gullwing model.

Intelligent material mix and low center of gravity
50 percent of the intelligently designed, weight-optimized aluminum spaceframe is made of aluminum sections, 26 percent of sheet aluminum, 18 percent of cast aluminum and 6 percent of steel. Maximum occupant safety requires the use of ultra-high-strength, heat-formed steel in the A-pillars.

The entire vehicle has been designed to achieve the lowest possible center of gravity. This applies both to the low connection points of the powertrain and axles, as well as to the arrangement of the rigid bodyshell structure, which has been kept as low as possible. Examples include the rigid flexural and torsional connections between the front and rear section and the passenger safety cell, which have been designed to use force paths that are as low as possible.

Passive safety
The aluminum spaceframe provides the basis for outstanding passive safety. The extensive safety features include the fixed roll-over protection system, three-point seat belts with belt tensioners and belt force limiters, and eight airbags: adaptive front airbags and kneebags, two seat-integrated sidebags and two windowbags deploying from the door beltlines.
The standard Blind Spot Assist helps the driver with a visual warning symbol and acoustic alert if the danger of a collision with another vehicle is detected when changing lanes.
Powerful AMG 6.3-litre V8 engine with 563 hp
The Mercedes-Benz SLS AMG Roadster has the same, muscular engine as the gullwing model. The 6.3-litre V8 with a peak output of 563 hp at 6,800 rpm makes the open-top SLS one of the most powerful sports cars in its segment. Its power-to-weight ratio is 6.5 pounds per hp. This naturally aspirated engine generates its maximum torque of 479 pound-feet at 4,750 rpm. The convertible SLS AMG accelerates from zero to 60 mph in 3.7 seconds (0-100 km/h in 3.8 s), and the top speed is 197 mph / 317 km/h (electronically limited) - which means that the Roadster has almost identical performance to the gullwing.

The high-revving 6.3-liter V8 engine has the typical characteristics of powerful racing engines. It responds immediately and effortlessly to accelerator movements. The use of a dry sump lubrication system allows for a considerably lower installation in the vehicle, yielding a lower center of gravity for high lateral acceleration and thrilling driving dynamics.
Achievement of demanding fuel consumption targets

Despite its uncompromisingly athletic character, fuel consumption has also been addressed. The SLS AMG consumes 13.2 litres per 100 kilometres (NEDC combined), corresponding to CO2 emissions of 308 grams per kilometre. Efficiency enhancements include the familiar AMG-exclusive, friction-optimized twin-wire arc-sprayed coating on the cylinder walls as well as the on-demand, map-optimized oil supply and intelligent generator management: during the engine's overrun phases, kinetic energy is used to charge the battery rather than wasted by simply generating heat. Conversely, the generator is switched to no-load operation during acceleration, thus reducing the load on the engine. Sophisticated catalytic converter technology enables current and future emission standards such as Euro-5, LEV 2 and ULEV to be met.

Rev-matching transmission with transaxle configuration and torque tube
The AMG 6.3-litre V8 engine delivers its abundant power to the rear transaxle via an ultra-light carbon-fiber driveshaft - similar to the setup used in the DTM C-Class racing touring car. The rev-matching transmission is mounted at the rear (transaxle), and connected to the engine housing via a torque tube. A carbon-fiber shaft rotates at engine speed in the torque tube. The advantages of this sophisticated solution lie in the rigid link between the engine and transmission and, in turn, the optimum support for the forces and torque generated.

The AMG SPEEDSHIFT DCT 7-speed sports transmission boasts fast gear changes with no loss of tractive force - in as little as 100 milliseconds. The driver has a choice of four different driving modes: "C" (Controlled Efficiency), "S" (Sport), "S+" (Sport plus) or "M" (Manual). In the Sport, Sport plus and Manual modes the automatic rev-matching function is active; all the modes can be selected conveniently via the rotary control knob on the AMG DRIVE UNIT. The RACE START function provides optimum traction for full power launches from a dead stop -- as does the mechanical differential lock, which is integrated into the compact transmission housing.

Sophisticated suspension layout with double-wishbone axles
The front-mid-engine plus transaxle configuration provides an ideal front/rear weight distribution of 47 to 53 percent. Mounting the engine behind the front axle has created ideal driving dynamics with precise steering, first-class agility, low inertia for spontaneous directional changes and outstanding traction. All four wheels are located on double wishbones with a track rod, a technology that has proven itself in motor racing right through to Formula 1. With a double-wishbone axle, the wheel location and suspension functions remain separate; the spring/damper struts are supported on the lower wishbone. The double-wishbone setup with its high camber and track rigidity positively locates the wheel with minimal elastic movements, providing the driver with an optimum sense of road contact when driving at the limits.

Wishbones, steering knuckles and hub carriers at the front and rear are made entirely from forged aluminum - substantially reducing the unsprung masses; this configuration also notably improves the suspension response. The long wheelbase of 105.5 inches not only results in outstanding straight-line stability but also low wheel load shifts, significantly reducing the vehicle's tendency to dive and squat when braking and accelerating. The broad track width - front 66.2 inches, rear 65.1 inches - provides lower shifts in the wheel loads from the inner to the outer wheel when cornering, enabling the tires to retain more grip.

New Adaptive AMG Sport Suspension
The new Adaptive AMG Sport Suspension with electronically controlled damping is available as an attractive optional alternative to the standard AMG sports suspension. It enables the damping characteristics to be modified at the touch of a button. Using a button on the AMG DRIVE UNIT, the driver can choose his own suspension setup. Three modes are available: "Comfort", "Sport" and "Sport plus". The current mode is shown in the instrument cluster.

Direct steering, differential lock and 3-stage ESP

The rack-and-pinion steering gear provides a consistently direct steering feel with a constant mechanical ratio of 13.6:1, in tune with the high expectations placed on a super sports car. The power steering provides speed-sensitive assistance and improves feedback for the driver as speed increases, valuable during high-speed straight-line driving. Mounting the steering gear in front of the engine on the integral subframe enables the engine to be set down very low. The SLS AMG comes with 3-stage ESP® as standard, providing the driver with access to the three "ESP ON", "ESP SPORT" and "ESP OFF" modes at the touch of a button. In "ESP OFF" mode, operating the brake pedal restores all the normal ESP® functions.

The acceleration skid control (ASR) system's traction logic is active in all three ESP® modes. If one of the drive wheels starts to spin, specific brake pressure is applied to improve traction significantly - especially in conjunction with the standard-fit mechanical multi-disc limited-slip differential. This means that the engine power is transferred to the road more effectively during aggressive driving.

Optional AMG ceramic high-performance two-piece braking system
The AMG high-performance braking system with two-piece brake discs at the front provides extremely short stopping distances even under enormous loads. Red-painted brake calipers at all four corners are available as an option. The optional ceramic two-piece brakes with even larger discs provide even better braking performance. The ceramic brake discs perform at even higher operating temperatures thanks to their greater hardness, all combined with an impressive weight reduction of around 40 percent. Reducing the unsprung masses has further improved both comfort and grip, and the reduced rotating masses at the front axle provide a more direct steering response.

Lightweight construction was  key when it came to the wheels: AMG light-alloy wheels based on the innovative flow-forming principle reduce the unsprung masses while improving driving dynamics and suspension comfort. In addition to the standard AMG twin 5-spoke light-alloy wheels, there is a 7-spoke wheel that's available as a no cost option. Weight-optimized 10-spoke forged wheels are  as an option. 265/35 R 19 (front) and 295/30 R 20 (rear) tires developed exclusively for the SLS AMG provide optimum performance. A tire pressure monitoring system is fitted as standard to permanently monitor tire pressure in all four wheels, with an individual display for each tire.

Production in Sindelfingen, market launch in Fall 2011
The convertible super sports car will be produced at the largest Mercedes-Benz production plant in Sindelfingen. The AMG 6.3-litre V8 engine comes directly from the AMG engine workshop in Affalterbach, where it is hand-assembled according to the traditional "One man, one engine" philosophy.

Aston Martin V8 Vantage N420, 2011

 

 

Aston Martin V8 Vantage N420, 2011

The Aston Martin has unveiled a new motorsport-inspired special edition; the Aston Martin V8 Vantage N420 which brings a new dimension of sporting prowess and dynamic ability to the V8 Vantage range.
Successor to the special edition V8 Vantage N400 of 2007, the Aston Martin V8 Vantage N420 is based upon the standard 4.7-litre, 420bhp, 180mph V8 Vantage and is available as a Coupe or Roadster, and with a six-speed manual or optional Sportshift automated manual transmission.

The Vantage N420 draws inspiration from the company's experiences at the Nürburgring 24-hour race. In the 2006 running of the annual Nürburgring endurance classic amongst a field of mostly motorsport homologated cars, Aston Martin entered a near-standard, road-registered V8 Vantage. Driven by a team of employees, including Aston Martin's CEO, Dr Ulrich Bez, the Aston Martin V8 Vantage - named 'Rose' by the team - finished 4th in class and 24th overall from a field of more than 200 specialised racing cars.
Since then Aston Martin has returned every year to compete in this gruelling endurance race, scoring a string of class victories and podiums with road-registered V8 and V12 Vantages and most recently the new four-door Rapide. Not only has this racing success spawned a burgeoning V8 Vantage GT4 customer programme run by Aston Martin Racing, but lessons learned in racing at the Nürburgring has led to aerodynamic and other performance developments being fed back into Aston Martin's road cars.
   
A generous standard specification and some unique options ensure the special edition Vantage N420 is both exclusive and distinctive, while also offering a 27kg weight saving - achieved through the application of carbon fibre - over the standard Aston Martin V8 Vantage.
On the outside, wider sills combine perfectly with a carbon fibre splitter, side strakes and diffuser, while bold 10-spoke diamond turned alloy wheels complete with gloss black finish, black mesh vents and 'Graphitic' tailpipe finishers complete the co-ordinated look.

The Inside,

the Vantage N420 offers an Iridium interior package, with graphite instruments, leather or Alcantara steering wheel, special N420 sill plaques and lightweight carbon fibre seats, complete with 'Race Track' stitching as in the Aston Martin V12 Vantage. Bluetooth connectivity, cruise control and Park Distance Control are also standard.

Cementing the Vantage N420's credentials as a special edition Aston Martin V8 Vantage tailored for the most discerning and enthusiastic drivers, it is fitted with the normally optional Sports Pack. This package combines revised springs, dampers and anti-roll bars for even more responsive and dynamic handling, while retaining the V8 Vantage's renowned poise, balance and long distance ability. Finally, a new sports exhaust system delivers a suitably rousing soundtrack.

A further distinctive feature is the availability of a new range of optional Aston Martin 'Race Collection' paint schemes. Pairing bold body colours with contrasting hues for the cant rails and radiator grille surround, they celebrate the marque's racing heritage. All of the company's successful N24 Vantage racers are celebrated, with 'Rose' yellow, 'Kermit' green and 'Elwood' blue all featuring in the collection along with traditional Aston Martin Racing green. The white and black car shown in the accompanying images wears the equally striking 'Asia Cup' livery.

Aston Martin V8 Vantage N420 prices start from £96,995.

Aston Martin DB9, 2011

The Aston Martin DB9 range has received a complete package of styling, engineering and equipment enhancements.
As the most successful Aston Martin of all-time (an honour it shares with the V8 Vantage) the DB9 has established itself as the definitive grand tourer, thanks to an enduring combination of understated elegance, sporting character and genuine luxury.

The car combines our unique Aston Martin character with an uncompromised design philosophy, craftsmanship and trademark Aston Martin performance ability."

The new package of improvements compliments these core qualities perfectly. Subtle styling changes freshen the Aston Martin DB9's appearance, with a new front bumper, bright finish radiator grille and a re-shaped lower intake featuring bright hexagonal mesh. New headlight bezels, re-styled sills, silver brake calipers, 20-spoke diamond turned alloy wheels and clear rear light lenses complete the external revisions.

Under the skin the Aston Martin DB9's passive damping system has been replaced by a new Adaptive Damping System (ADS), which offers enhanced ride comfort together with sharper handling when switched to Sport mode. The ADS system is offered as standard equipment across the Aston Martin DB9 range, encompassing both Coupe and Volante (convertible). A new tyre pressure monitoring system, a revised Bluetooth microphone system and the addition of a new Double Apex alloy finish trim and Bang & Olufsen hi-fi options broaden the Aston Martin DB9's specification.

Aston Martin's Product Development Director, Ian Minards, explains that it is all part of an ongoing commitment to continual improvement: "The Aston Martin DB9 was the first car built at Gaydon adopting the VH architecture. It has evolved every year since, with significant changes including a power upgrade and successive reductions in CO2 emissions. The latest package of improvements goes further than ever, highlighting the Aston Martin DB9's qualities as a true sporting GT and underlining its role as the backbone car of our range."

The Aston Martin DB9 is available as either Coupe or Volante (convertible) with rear mid-mounted six-speed manual gearbox as standard or optional 'Touchtronic 2' six-speed automatic transmission. Production of the revised Aston Martin DB9 is already underway, with deliveries commencing in July. Prices start from £122,445 for the Aston Martin DB9 Coupe and £131,445 for the Aston Martin DB9 Volante.

Background
The introduction of the DB9 marked the beginning of Aston Martin's 21st Century renaissance. The first new model to be built at Aston Martin's headquarters in Gaydon, Warwickshire, and the first to be built around Aston Martin's rigid, lightweight, bonded aluminium VH architecture; the Aston Martin DB9 was an immediate and unparalleled success, setting a new tone for Aston Martins of the future.

Since its launch in 2003 some 12,500 DB9s have been produced and delivered to customers in 34 countries. This establishes it as the most successful Aston Martin model of all-time (jointly with the V8 Vantage), surpassing total sales of the DB7. Current Aston Martin DB9 production volume is around 1,500 cars per year.

Engineering
Since the DB9's introduction Aston Martin has demonstrated the versatility of the VH architecture by developing the Vantage, DBS and Rapide model ranges. In the process Aston Martin's engineers have gained an increasingly detailed understanding of the VH platform, which in turn has led to the constant improvement and evolution of existing established models.

In the package of improvements for Aston Martin DB9, hardware changes focus on the chassis, featuring a standard Adaptive Damping System (ADS) which offers a system constantly evaluating the optimum damper condition, similar to that seen on the DBS and Rapide models. Controlled by a button on the centre console, the two-stage adaptive dampers can be switched between their default mode, which is optimised for ride comfort, and a firmer sport mode, which delivers tighter body control and a more responsive feel. Such is the success of the Aston Martin DB9's new damping system that the DB9 Sport Pack upgrade has now been discontinued. However a Sport design alloy wheel is available as an option.

Design
Improving upon what many consider to be one of the most beautiful cars in the world is a delicate exercise. According to Aston Martin's Director of Design, Marek Reichman, subtlety and fine attention to detail is the key: "The beauty of an Aston Martin comes from harmonious proportions, a ground-hugging stance, taut surfacing and a complete and thorough attention to detail. The Aston Martin DB9 epitomises these qualities; it is beautiful but subtle - not attention seeking."

At the front a new bumper is the main change, with a re-shaped lower intake featuring hexagonal mesh to compliment the new bright finish radiator grille. New headlamp bezels complete the fresh nose treatment. In profile the Aston Martin DB9's sill has also been changed, with a more prominent 'hockey stick' curve ahead of the rear wheels. Marek Reichman explains: "The DB9 remains one of the world's most beautiful sports cars and is instantly recognisable as an Aston Martin; the changes we have introduced here modernise the Aston Martin DB9 to keep it at the forefront of automotive design."
Other changes include silver brake calipers, 20-spoke diamond turned alloy wheels as standard, together with new design option wheels and a bright finish grille. Clear rear light lenses are also standard. Inside Double Apex alloy finish is now added to the list of options, along with the exceptional BeoSound audio system from Bang & Olufsen.

Motorsport
Mirroring the Aston Martin DB9's road-going success, Aston Martin Racing's DBR9 and DBRS9 endurance racers have proved hugely successful on racetracks around the world. With a total of some 20 DBR9 and 30 DBRS9s built and delivered to customer teams around the world, Aston Martins have consistently scored victories in a host of national and international championships.
Since winning on its race debut, at Sebring in 2005, the DBR9 has been established as a constant and hugely competitive car in the GT1 category, scoring back-to-back class victories at the greatest 24-hour race of them all - Le Mans - in 2007 and 2008.
