Key points
"In another move that benefits the vehicle’s weight, the
eight-cylinder engine from the production model has been replaced under
the hood by a turbocharged, inline five-cylinder engine that can trace
its roots back to another Audi sports car – the TT RS. In the Audi
quattro concept, the longitudinal FSI turbo produces 300 kW (408 hp) and
accelerates the car from 0 to 100 km/h (62.14 mph) in only 3.9 seconds.
Torque is distributed as needed via a six-speed manual transmission.""
"As a complement to the new quattro drivetrain, the Audi quattro
concept also features the sport differential, which actively distributes
torque between the rear wheels. When turning into or accelerating in a
curve, the majority of the torque flows to the outside wheel and pushes
the vehicle into the curve, nipping the tendency to oversteer or
understeer in the bud.
The sport differential is a state-of-the-art rear differential. A
superposition gear comprising two sun gears and an internal gear was
mounted on the left and the right of a conventional rear differential.
It turns 10 percent faster than the drive shaft."
