The future of racing, as envisioned by the engineers behind the Audi Quattro Concept. What does the racing model have that the main concept does not? Find out inside.

Those attending the Paris Motor Show may want to give the Audi stand a closer look.  There, fans of the brand will find a prototype of the Audi Quattro Concept fit for the races.

Painted in red, white and black as an homage to the early 1980s Audi rally cars, the car has a number of high performance features not seen on the main concept vehicle.  Clearly noticeable attributes include the ventilated hood, a massive front lip spoiler, aerodynamic changes around the wheels and polycarbonate racing windows.

A big rear wing was also added, with a German flag design on its sides.  It looks as though both cars use the same center-locking 20-inch alloy wheels.

Audi did not say what engine the rally-inspired concept is using.  The main concept utilizes a 402-horsepower (300-kW, 408-PS) 2.5-liter turbocharged five-cylinder engine.  The unit delivers up to 480 Nm (354 lb-ft) of torque, letting the car accelerate from 0-100 km/h in 3.9 seconds.

If you're heading out to the Paris Motor Show, make sure you snap a few pics of Audi's vision for the near future of racing.
