Will Audi's top-performing supercar be able to beat a car that embodies Audi's motorsport heritage? The team at Carwow tested a Group B Audi Quattro rally car against an Audi R8 V10 Spyder on the drag strip.

As the rain begins to fall on this battle between Audi greats, the results become more interesting. Carwow's Group B Audi Quattro rally car is steeped in motorsport excellence.

As a result of the class-leading Quattro rally car, Audi emerged as the champion of all-wheel-drive performance cars in Group B. From the late 1980s until the series was cancelled by the FIA in 1990, Audi dominated Group B.

Audi Quattro rally cars were powered by turbocharged aluminum engines that could produce 500 horsepower and 354 pound-feet of torque.

In the 3-liter class, turbocharged engines have a displacement multiplied by 1.4, so the 2.1-liter displacement was chosen in order to meet homologation requirements.

To keep the weight down and ensure strength, the Quattro rally car's body is made of unique carbon-Kevlar material.

The Audi heritage collection owns and maintains this particular Quattro rally car for promotional events and maintenance. PDK dual-clutch automatic transmission was even developed using this exact car by Porsche.

Audi's R8 V10 Spyder will take on this legend of motorsport. A naturally aspirated 5.2-liter V10 engine produces 620 horsepower and 427 pound-feet of torque in this drop-top supercar.

Powered by Audi's Quattro all-wheel-drive system, this screaming V10 is mated to a 7-speed dual-clutch transmission. Will Audi's most impressive rally car beat its most exciting production car in a drag race? Come on, let's find out.
