Porsche 911 GT3 and dodge viper srt 10 and audi R8 race on the autobahn
In 2008, with the introduction of the 510 cu in (8.4 L) V10, the Viper produced 600 bhp (450 kW) at 6000 rpm and 560 lb·ft (760 N·m) at 5100 rpm, and also received better flowing heads with larger valves, Mechadyne cam-in-cam variable valve timing on the Exhaust cam lobes, and dual electronic throttle bodies. The rev limit was able to be increased by 300 rpm due to the improved valve-train stability from both the new camshaft profiles and valve-springs. The development of the engine was done with some external assistance from McLaren Automotive and Ricardo Consulting Engineers. Electronic engine control is developed by Continental AG, the controller is capable of monitoring the crankshaft and cylinder position up to six times during each firing and has 10 times more processing power compared to the previous unit.
Changes outside of the engine were less extreme. The Tremec T56 transmission has been replaced with a new Tremec TR6060 which now has triple first gear synchronizers and doubles for higher gears. The Dana M44-4 rear axle from the 2003-2006 model now has a GKN ViscoLok speed-sensing limited-slip differential that greatly helps the tires in getting grip under acceleration. Another performance upgrade was the removal of run-flat tires; the new Michelin Pilot Sport 2 tires have increased driver feedback as well as grip and, along with revised suspension (springs, anti-roll bars, and shock valving), has made the Viper more neutral in cornering.
The Audi R8 was initially equipped with a 4.2 litre V8 internal combustion engine. Specific detail: it is an all-aluminium alloy 32-valve (four valves per cylinder) petrol engine, utilising Fuel Stratified Injection (FSI), and has a displacement of 4,163 cc (254.0 cu in). It develops a motive power output of 309 kilowatts (420 PS; 414 bhp), and generates 430 newton metres (317 ft·lbf) of torque, on 98 RON 'Super Unleaded' petrol. It is basically the same engine used in the B7 Audi RS4, but is modified to use dry sump lubrication system. This V8 is a highly reworked, high-revving variant from the existing 4.2 litre V8, but includes cylinder-direct fuel injection (Fuel Stratified Injection), and four valves per cylinder, instead of five (as used on the non-FSI variants). It also uses two chain-driven dual overhead camshafts (DOHC) per cylinder bank, and utilises variable valve timing for both inlet and Exhaust camshafts.
A new additional variant with a 5.2 litre Fuel Stratified Injection (FSI) V10 engine was added on the 9th of December 2008, which produces 386 kW (525 PS; 518 bhp) and 530 N·m (391 ft·lbf).
The transmission options are either a Lamborghini sourced manual gearbox with metal gate for the shift lever, or an Audi-developed "R tronic" gearbox - which is a single-clutch semi-automatic electrohydraulic manual transmission, without a traditional clutch pedal. These options are the same as those available on the Lamborghini Gallardo. A double-clutch Direct-Shift Gearbox (DSG), now badged by Audi as "S tronic", is not available (as of December 2008
As with earlier models, such as the Carrera RS 2.7 of 1973 and the Type 964 911 RS of 1991, Porsche offered an RS version of the 997 GT3. In common with its predecessors, it provides a homologation model for use in a range of racing series.
Thanks to a close-ratio six-speed transmission with a single-mass flywheel, the engine revs up even more freely, thus enabling the 911 GT3 to sprint from zero to 100 km/h (62 mph) in 4.0 seconds while reaching 200 km/h (124 mph) in 13.3 seconds. Maximum speed is 310 km/h (193 mph).
The RS is 20 kg (44 lb) lighter than the GT3, weighing in at 1,375 kg (3,031 lb). This weight-saving was achieved by the use of an adjustable carbon fiber wing, a plastic engine cover, and a lightweight plastic rear window. The weight savings gives the RS model corresponding engine power to curb weight ratio of 300 bhp (220 kW) per tonne.
One characteristic of the new RS is the body, which is 44 mm (1.7 in) wider at the rear (a legacy from the Carrera 4 models with which it shares its shell) by comparison with the 911 GT3. The muscular-looking rear end conceals a wider track that not only improves directional stability but also increases the potential cornering grip of the two-seater coupe. On the other hand, drag is increased, and top speed reduced.
In addition to the new technology featured in this flat six motor car, the paint scheme and body panels are all designed specially for this car. For the RS version, the limited edition orange color was mixed specially for this car.

Yesterday I had a great day during an ''Autobahn Run''. We had a few nice
cars together and I participated with my GTI. In this first video you see
two black Lamborghini Gallardos, one is totally stock, but the other has a
Tubi Exhaust and Testpipes. Thanks to
that modification, this Gallardo has a very loud and high sound!
I hope you like this video, stay tuned for more Autobahn action!
