Maserati GranTurismo MC Concept, 2008

 
  •  Maserati GranTurismo MC Concept, 2008

Races have always been the most demanding test-bed for all cars. Traditionally, reliablity and performance are checked on the circuit. It is in races that new technologies and materials are tried out. And it is on the circuit that Maserati has decided to raise the much praised sporty verve of its Maserati GranTurmismo S to even higher levels to create the Maserati GranTurismo MC Concept.

Style
The changes the designers of the Maserati Style Centre have made to the GranTurismo S to create the racing model have improved its performance and above all its aerodynamic efficiency, without disturbing to its elegant, curvaceous line. The radiator grille of the Maserati GranTurismo MC Concept features two large air intakes - designed to increase the air flow to the engine and brakes - and an aerodynamic bottom trim. The front mudguards, with increased track, are also new, as is the engine hood with a dynamic air inlet and two additional air vents.

The car's profile has also been the subject of in-depth aerodynamic analysis, leading to the introduction of unusual side air vents, linked to the new miniskirts under the doors. What's more, the rear of the Maserati GranTurismo MC Concept has new-design fenders to accommodate the air vents and centrally located tailpipes. Last but not least, the boot spoiler is larger in size to increase the down force generated by the profile, thus compensating for the aerodynamic effect of the front spoiler.

Development
The Maserati GranTurismo MC Concept has been developed on the basis of the Maserati GranTurismo S, launched at the Geneva Motor Show on 6th of March 2008. The Maserati Racing Department engineers have made major improvements to reduce the car's weight while also engancing its performance. The mapping of the engine installed on the Maserati GranTurismo MC Concept has been revised to further increase performance without impairing reliability: the unit is now generating 330.9 kW (450 hp), with torque of 510 Nm at 4,750 rpm. The intake and exhaust systems have also been revised through the installation of a high-performance conical air filter combined with an exhaust system fitted with racing-type catalytic converters and silencers.

The suspension setting of the Maserati GranTurismo MC Concept, together with improved weight distribution and new single-string racing dumpers, plus new 12"x18" fron and 13"x18" rear wheels and slick tires, guarantee a striking increase in the car's dynamic performance compared to the Maserati GrantTurismo S.

The brake system has received an upgrade to withstand the stress typical of use on a track, whit adoption of larger discs and monobloc racing calipers.
The chassis has been significantly lightened and stiffened thanks to application of an integral welded roll cage, as required by the FIA regulations.

The coachwork, partially modified to meet new technical requirements, is in composite materials. The specific electrical system, the dedicated instrumentation including an integral data acquisition system, and the indispensable safety devices, complete the equipment of the Maserati GranTurismo MC Concept.

Koenigsegg CCR, 2004

 
 
  •  Koenigsegg CCR, 2004

The Koenigsegg CCR is an automobile and supercar made by Koenigsegg. Designed and manufactured in Ängelholm, Sweden, it debuted at the 2004 Geneva Auto Show. It briefly held the world speed records for a production car.

Overview
The CCR is based on the Koenigsegg CC8S, featuring more power and higher performance. The improved-power engine was made possible by the use of a Lysholm twin-screw supercharger and a new titanium exhaust system. This takes the power output to a maximum of 806 hp (601 kW) at 6,900 rpm. Torque is also distributed evenly and peaks at 920 N·m (678 ft·lbf) at 5,700 rpm. Newer versions (the Koenigsegg CCX) appear to use twin Rotrex centrifugal type superchargers instead, providing the same power, but lowering the peak torque point from 5,700 to 5,400 rpm. (Note: This information of performance is partially updated in their official page.)

Externally the CCR looks similar to the CC8S, but features a new side air-intake design, a tweaked headlight arrangement, a revised rear-end, larger brakes, more power and new front splitters for optimized downforce. Like the CC8S, the CCR is a two-seat coupe with a mid-engine, featuring large scissor doors that open by rotating up and forward.

To honour the Swedish Fighter Jet Squadron No. 1, (Johan röd) which had occupied the current facility of Koenigsegg, the CCR is adorned with a symbol of a ghost, the symbol of the squadron.

On a History Channel special on the CCR (Aug, 2006), Koenigsegg states that the base price for the CCR is approximately US$590,000.

Testing history
The manufacturers claim the CCR is the fastest road car in the world, with a theoretical top speed of more than 385 km/h (240 mph).

On February 28, 2005, at 12.08 local time, the Koenigsegg CCR broke the production road car speed record, achieving a new official top speed of 387.87 km/h (241 mph) at Italy's Nardo Prototipo proving ground. A team of five Koenigsegg engineers and mechanics together with founder Christian von Koenigsegg ran a technically standard CCR, driven by famous supercar test driver and veteran record breaker Loris Bicocchi. The car was clocked using Tag Heuer´s Splitmaster 650 with photocells stationary at the track, recording the average speed during 1 km.

The CCR took the record from the McLaren F1, which held the record for over 10 years of 386.7 km/h, set on the 9 km straight track at the VW Ehra facility in Wolfsburg, Germany. The CCR ran on the Nardo/Prototipo track, a circular track with a circumference of 12.5 km. This means that the car is driven in a constant turning motion, which makes the exercise and speed even more impressive. The steering wheel at this speed is kept at around 30 degrees of constant angle, a fairly sharp angle for the speed. On the same track, the F1 managed an unofficial record of 372 km/h.

In May, 2005 not long after the CCR claimed the record, a prototype of long awaited Bugatti Veyron took the crown with a top speed over 400 km/h (249 mph). The final production model of the Veyron reached a speed of 407.5 km/h (253.2 mph) in the hands of Car and Driver in their November 2005 issue.

Ferrari P540 Superfast Aperta, 2011

 

Ferrari P540 Superfast Aperta, 2011

The first shake-down has been held at Fiorano of a very special one-off, the Ferrari P540 Superfast Aperta, built for an American client. The car, the second in a new Special Projects programme created by Ferrari to meet requests from the most discerning clients and collectors to create truly unique models, is based on the Ferrari 599 GTB Fiorano and was inspired by a Carrozzeria Fantuzzi-designed Ferrari built specifically for the 1968 Fellini film, Toby Dammit, itself inspired by one of the tales of Edgar Allan Poe.

With the Special Project's approach to producing such individual one-offs, the Ferrari P540 Superfast Aperta respects all existing international safety and homologation requirements and is thus road legal. The car was designed by Pininfarina and built in Maranello, and the client was directly involved in each stage of its development. As the 599 GTB Fiorano donor car is a coupé, considerable effort went into strengthening the chassis by using finite element analysis in development and the increase in weight was kept down to just 20 kg by employing carbon-fibre extensively. From the initial sketches to the final, road-legal car took just 14 months.
