Each race features 18 V8 powered racing cars built according to the technical regulations of the Deutsche Tourenwagen Masters.  It will be the twelfth season of Deutsche Tourenwagen Masters since the series' resumption in 2000.  The 2011 season will be the first season that cars will not run on Dunlop tyres, instead running on Hankook tyres in the first year of a three-year control-tyre deal.  It was the final season running the 4-door saloon style spec cars, which has been the series' sole car style requirements since 2004.  It was also the final season that all DTM cars running with the manual gearbox shifters before all DTM cars switched to sequential semi-automatic gearbox paddle shifters at the following season. The Realpha, also known as RE, was a Rhodesian Formula One racing car.  The car was built by Ray Reed at his base in Gwelo, and was structurally based on a Cooper.  Like many South African home-built Formula One cars of the time, it was fitted with an Alfa Romeo Giulietta engine. The Dauer 962 Le Mans is a sports car based on the Porsche 962 racing car.  Built by German Jochen Dauer's Dauer Racing, a racing version of this car went on to win the 1994 24 Hours of Le Mans with the support of Porsche through the use of regulation loopholes. The Burton is a Dutch sports car based on French 2CV technology.  The Burton is an open, nostalgic-looking sports car built on the chassis of the 2CV with a modern glassfibre bodykit.  The car can be built as an open two seater, or with a hardtop with gull-wing doors or with a custom made convertible roof.  From the beginning of 2002 the Burton is available all over Europe. The Cooper Car Company is a car manufacturer founded in December 1947 by Charles Cooper and his son John Cooper.  Together with John's boyhood friend, Eric Brandon, they began by building racing cars in Charles's small garage in Surbiton, Surrey, England, in 1946.  Through the 1950s and early 1960s they reached motor racing's highest levels as their rear-engined, single-seat cars altered the face of Formula One and the Indianapolis 500, and their dominated rally racing.  Due in part to Cooper's legacy, Great Britain remains the home of a thriving racing industry, and the Cooper name lives on in the Cooper versions of the Mini production cars that are still built in England, but are now owned and marketed by BMW. The Holden Monaro 427C was an Australian built and designed GT style race car based on the Holden Monaro CV8 road car.  The car ran in the Procar Australia-run Australian Nations Cup Championship and at the short-lived Bathurst 24 Hour race at the famous Mount Panorama Circuit in Bathurst. The Holden SSX is a concept sports–hatchback prototype car based on the Holden VY Commodore, with a more aggressive edge.  The front has a bold, deeper fascia with twin projector headlights, foglamps and an exclusive front grille.  The back is totally redesigned and features a deep, aggressive bumper and blackened taillights, plus hatchback entry, making it (Rover SD1 and Holden Torana aside) one of the world's first V8 hatchback cars.  The car features a "Kryptonite" green metallic paint job, with a black and silver interior.  The dials light up in a deep red when lights are on.  The car is a concept only; it formed part of the extensive Holden display at the Sydney International Motor Show from October 18 to October 27, 2002. Automeccanica was a Greek automobile producing company.  Founded in 1979, it was one of the companies that produced the "passenger-utility" type of vehicle popular in Greece at the time for tax categorization reasons.  Its creators were former executives of "Autokinitoviomihania Ellados" (meaning 'Greek Car Industry') a company founded in 1975 to also produce vehicles of this type – it assembled Italian Fissore models based on Fiat products, as well as other Fiat models and variants.  Automeccanica followed a different path, building the "Zebra" model, a passenger-utility car based on the "Daihatsu Charade", as well as assembling the "Charade" itself.  In 1985, when the law favoring the "Zebra"-type vehicles changed, Automeccanica stopped its production (after about 2,000 units had been built) and started licence production of the Soviet Lada Niva model, while it developed its own cabrio-version of the car.  In 1988 it acquired its former "father" company, "Autokinitoviomihania Ellados" and the latter's factory in Thiva.  Automeccanica went out of the car-construction business in 1995. The General Motors Stir-Lec I was a concept hybrid electric car based on the Opel Kadett body in 1969.  The power plant consists of 14 lead-acid batteries in the front of the car which transfer energy to a rear-mounted 3 phase electric induction motor, in turn driving the rear wheels.  The Stir-Lec I had a top speed of 55 mph .  While the car is running, the batteries are constantly recharged by a small Stirling engine in the rear.  The engine was allegedly so quiet it was hard to determine if it was running or not, just by sound.  Since the Stirling is an external combustion engine, the exhaust has virtually no odor and pollution levels can be made very low.
