Rover 75 V8

Rover 75 V8

The new full-depth open grille is reminiscent of the archetypal Rover P5B. Like the P5 and other V8-powered Rovers since, the imposing and distinctive appearance of V8 derivatives is matched by a motoring experience that has no peers in this segment of the market.
The Rover 75 V8 four-door saloon is derived from the company's much-respected large car platform. Driving the rear wheels, the in-line mounted 4.6-litre engine is matched to a smooth automatic transmission to offer refined yet effortless performance entirely in keeping with the long-distance, no object associations of this famous marque.

Rover's famously comfortable seats have been trimmed in leather, designed to complement Rover's new Light Oak theme on Connoisseur SE, or Dark Oak on Contemporary SE models.

The proven 4.6-litre engine is now mated to a smooth automatic transmission. A new electronic engine management tune and unique exhaust and intake systems provide an impressive combination of refined cruising and an assertive soundtrack under hard acceleration.
Overview
The Rover 75 V8 is the antithesis of the accomplished ZT 260 V8, for while the MG can capably deploy its power for performance and deliver high levels of driver involvement, the Rover is a wholly more refined experience. While the experience of the ZT has permitted the clever installation techniques of the large capacity engine and rear-wheel drive power train to be incorporated within the robust body shell, the change was to produce a car of supreme comfort, refinement and power-in-reserve characteristics.

Powertrain
The Rover 75 V8 utilises the proven 4.6-litre V8 engine, widely used in North America to power the iconic Ford Mustang. Modifications have been made to the Powertrain to assist in packaging the engine while MG's engineers have also developed new intake, exhaust and emissions control systems to ensure the vehicle complies with stringent European noise legislation with no loss of power or torque. A new electronic engine calibration helps ensure the car exceeds current European emissions legislation. The automatic transmission has four speeds and is manufactured in North America.

The exhaust system, twinned for most of the length of the car, has four subtly mounted tailpipes, kept below the rear bumper. Outside the system produces a classic V8 burble, while inside the cabin remains quietly subdued, yet retains the note of a thoroughbred V8.

The Dana Hydratrak limited slip differential system option, utilises vane-pump principles to ensure continuous and seamless torque transmission to both rear wheels in the event of wheel speed differential.

Steering and Suspension
The Rover 75's steering and suspension systems have evolved radically to match the performance of the V8 power unit. Developed by driving enthusiasts for enthusiasts, the team focused their efforts on honing the car's classic rear-drive handling to provide progressive control under the widest range of conditions. The result is a car that blends day-to-day ease of use with the driver-rewards of a true thoroughbred.

Power steering is now via a new forward mounted rack layout providing excellent feel and driver feedback to the leather-bound wheel.

The geometry of the 75's Mac Pherson strut front suspension has been tuned to the requirements of the new chassis. A new design of upright is matched to Eibach linear rate springs and a new, larger diameter anti-roll bar. Wheel response is controlled by Bilstein monotube struts, which combine a large piston area for fine tuning resolution with very high bending stiffness for improved camber control.

A new multi-link rear suspension has been evolved from the design created for the ZT 260 V8. A new six-mount subframe houses the rear drive differential, while each wheel is located by three lateral links (two steel and one light-alloy) and a light alloy trailing arm. Compound rate springs, sourced from specialist Eibach, work in conjunction with Bilstein monotube dampers to provide excellent wheel control.

Wheel designs are available in a 17" Star-spoke design with 215/50 profile tyres provides supreme comfort levels, and in 18" with Contisport 225/45 R18 tyres. Both have a unique machine-faced feature.

Braking
The Rover 75 V8 has a new H-split braking system providing excellent stopping power. At the front, proven large capacity 325mm ventilated discs and sliding-pin callipers are specified. At the rear a new AP-Racing sourced brake system is specified with 332mm ventilated discs and opposed piston alloy callipers.

Interior environment
A new HEVAC (Heating, Ventilation and Air conditioning) unit is fitted to the V8. The new unit is a water-blend design featuring a dedicated electronic control unit to drive servo-motor valves to regulate the water flow around the heating circuit. This system has been refined to offer similar levels of response and control to the existing 75's acclaimed air-blending system. All models feature ATC (Automatic Temperature Control), using the familiar user-friendly interface of other 75 models.

Saleen S7

Saleen S7

The Saleen S7 is a high-performance sports car that was jointly designed by RML and Saleen, Incorporated and is currently being built at Saleen's headquarters factory in Irvine, California. It is constructed with a unique hybrid of a steel spaceframe and aluminum honeycomb panels encased with autoclave-cured carbon fiber bodywork. Engineering of the unique engine that is used in the S7 was headed by Billy Tally, Saleen's current Vice President of Advanced Engineering.


Saleen S7 race cars were sold prior to 2002, but the first Saleen S7 road car to be sold was a 2003 Lizstick Red chassis #018 that was delivered on June 6, 2002. Prior to 2005, the S7 was naturally-aspirated and produced 550 hp (410 kW). For the 2005 model year, the engine was equipped with two turbochargers and power output was increased to 750 hp (559 kW). The car was designed to be a Twin Turbo setup from the beginning, however.


The Saleen S7 has also been campaigned in racing events around the world. It has been met with some success in the IMSA's American Le Mans Series, where it competes in the GT-1 class. In all, it has won over 40 events around the globe; mostly in the American Le Mans and in the FIA GT championship. Saleen also introduced factory supported aftermarket packages for 850 and 1035bhp in early 2006. This option would add around $75,600 to the list price. In late 2006 there will be a third party top speed run for the 750bhp S7.

Saturn Vue

Saturn Vue

Saturn introduced the all-new 2008 Saturn Vue, a compact five-door crossover vehicle with European and sporty ride and handling. The vehicle was revealed at the Greater Los Angeles International Auto Show.

Ride and handling
At the core of the Vue's European driving character is a stiff, steel body-frame integral structure. Ride and handling is augmented by model-specific tuning of spring rates and wheel travel. Front and rear stabilizer bars, MacPherson strut independent front suspension and independent multi-link rear suspension, along with a double-isolated engine cradle, add to the smooth ride. Hydraulic power-assisted steering on V-6 models, standard four-wheel anti-lock disc brakes, standard traction control and standard GM StabiliTrak electronic stability control provide outstanding vehicle control.

Safety
In addition to the handling features that help drivers avoid crashes, the all-new Vue helps protect occupants with a long list of standard crash protection safety features. Dual-stage front seat air bags, front seat side thorax air bags and head curtain air bags covering front and rear rows are standard on all models.

Complementing the air bags is GM's rollover sensing system, which uses sensors to proactively predict vehicle tip-up on a flat road surface and apply brake force to the outside front and rear wheels to reduce lateral force in the vehicle. It also activates the roof rail air bags if sensors determine an impending rollover. Other standard safety features include front-row dual safety belt pretensioners, disengaging collapsible pedals and active head restraints.

The Vue comes standard with GM's OnStar safety and security system, including a one-year subscription to the Safe & Sound plan. The OnStar service includes Advanced Automatic Crash Notification (AACN), making crash data available to emergency services to potentially dispatch the appropriate life-saving personnel and equipment to crash scenes faster.

Exterior
The new Vue's exterior exhibits Saturn's new European cues, with a look that is clean, sculpted and distinctively sporty. Tight wheel-to-body relationships, large jeweled headlamps and a sweeping upper profile line contribute to the Vue's striking design. The tapered roof line is one of the design cues drawn from the PreVue concept shown at the 2006 New York Auto Show.

Sixteen-inch alloy wheels are standard on XE models, while larger 17-inch alloy wheels come with the uplevel Vue XR. XE and XR models are further distinguished from each other with specific fascias, rockers and wheel opening trim. The Red Line model, to be unveiled later, will sport its own performance-inspired design cues.

Interior
Inside, the Vue continues the upscale theme with refined materials and precise fit and finish. Designers used lighter colors to bring a sense of spaciousness to the cabin, and incorporated an array of useful storage solutions.

The interior offers a host of comfort and convenience features, many of which are uncommon in the segment. These include optional eight-way power driver's seat; standard flip-down second-row armrest with storage; standard CD stereo with MP3 capability; standard driver information center in instrument cluster; available automatic climate control system with electronic controls; available navigation system; and an optional enhanced convenience package that includes an automatic rain-sensing wiper system, remote start, universal home remote and heated windshield washer system.

Other cabin highlights include:
* Rich materials including chrome accents on the air vents, center stack controls, instrument cluster and speakers
* Bolstered seating upholstered with two levels of flat-woven fabric with specific inserts; leather seating is available on most models
* Low-gloss, low-glare upper instrument panel with embossed grain
* Amber backlighting in the instrument panel and center stack control faceplates
* Ample covered, flocked and damped storage, including a locking glove box big enough for a medium-size purse
* A sliding storage bin under the front passenger seat
* Flat-folding 60/40 split rear seatback
* A rear cargo management system that uses upper and lower rails and storage nets to accommodate storage nets for everything from beverage bottles to home-improvement accessories

Powertrain
No other vehicle in the segment will offer as wide a range of engine choices as the 2008 Vue. The XE FWD and Vue Green Line models are equipped with the 2.4L Ecotec with variable valve timing. It produces 164 horsepower (122 kW) at 6,300 rpm and 160 lb.-ft. (221 Nm) of torque at 4,500 rpm. It is mated to the Hydra-Matic 4T45, four-speed, electronically controlled transaxle. A five-speed manual will be available on four-cylinder Vue XE models in early 2008.

All-wheel-drive Vue XE models come equipped with a 3.5L V-6 engine, delivering 215 horsepower (260 kW) at 5,900 rpm and 220 lb.-ft. (304 Nm) of torque at 2,800 rpm, with a broad torque curve and good low-end torque for quick acceleration.

Vue XR and Vue Red Line, are powered by GM's sophisticated, high-feature 60-degree dual overhead cam 3.6L V-6 VVT that delivers 250 horsepower (186 kW) at 6,500 rpm and 243 lb.-ft. (329 Nm) of torque at 4,400 rpm.

All Vue models equipped with V-6 engines receive the new Hydra-Matic six-speed automatic transmissions, which helps maximize powertrain performance and economy.
