The Audi R8 is a mid-engine, two seat sports car built by the high performance quatro GmbH division, all units are based on the Lamborghini Gallardo platform with every version using the Audi (AWD) All Wheel Drive system. The R8 series comes in many flavors to suit virtually anyone’s power tastes; there are also many concept versions on the drawing board with a number of prototypes doing trials as of this printing. The bodies are mounted on an aluminum monocoque frame; with the construction methods integrating space frame principals. Audi announced at the end of the 2005 racing season that the very successful prototype R8 would become a production vehicle for the 2007 model year. Field tests were done through 2006 with 24 Hours of Le Mans winner, Jacky Ickx, commenting that it would be the best handling car on the road.
Audi TT Bimoto was first created by MTM in 2002 with evolution taking a full six years to reach a suitable road legal and reliable production model. The power is generated by two four cylinder inline engines occupying two engine compartments with each engine contain aluminum pistons, polished/blueprinted connecting rods, and high lift camshafts. The powerful blocks are topped with gas-flowed heads, holding the close tolerance camshafts, and solid lifters allow the engines to safely run up to 8,800 rpm. KKK turbo-chargers containing large injectors supply the fuel needs while on the downside of them massive inter-coolers help maintain cool heads at high speed and sit on the large, unique exhaust manifolds. The one per engine stainless steel free flow exhaust pipes are to encourage low back-pressure and each have semi-race catalytic converters with each system sharing a central wastgate pipe. Each engine powering the still evolving Bimoto generates 505 hp (kW) and 382 ft-lb torque for a total of 1010 hp for this model. The car generates similar power to the Veyron but weights 1100 lbs less. The model has a top speed of 244 mph (393 km/h) and it will do 0-100 km/h (62 mph) in 3.1 seconds. . Due to the high speeds this car is capable of, down-force is not just desirable, it is a necessary feature for safety. The carbon fiber/aluminum body carries a front splitter, flat carbon fiber under-tray, rear deffuser mounted underside, with both down-force and directional stability increased by the rear mounted vertical fin.

The reviews for the twin turbo-charged 5 Liter V10-RT6 Clubsport (images below) by MTM are, for the most part, very positive but mixed; however I will take the middle ground and try to give an objective and unbiased overview. This model in its last original form was a luxury appointed sedan but the rear seats have been jettisoned with total disregard for back seat drivers to make room for a rear mounted roll cage instead and the front now holds two carbon fiber bucket seats made by Ricaro which are equipped with six point harnesses. The front end has been revised with a discreet carbon fiber front spoiler, carbon fiber rear defuser added, and the suspension can be adjusted to raise or lower the vehicle from 10 to 45 inches to meet the demands of any variety of driving conditions. The optional 19” or 20” Bimoto wheels are clad with the basic equipment Michelin Pilot Sport PS2 tires and are fine for normal travel but these can be optionally upgraded with any one of four different compound treads if you plan on pushing the limits to above 200 mph (320 km/h) regularly.
The stock V10 engine gives 571 hp and receiving only modest external revisions such as the addition of a high flow air filter, an MTM stainless exhaust system, catalyst, and rear silencer with four 80 mm pipes; two of them containing throttle valves. With only these minor modifications the engine ECU( Electronic Control Unit) has been fine tuned and it now produces 730 hp (537 kW) with 860 Nm of torque doing 0-60 mph (97 km/h) in 3.6 seconds and from o to 124 mph (199.56 km/h) in 11 seconds with a top speed of 225 mph (362.1 km/h).
