Drawing its inspiration from the original 1980 Audi Ur-Quattro and using some underpinnings from the current RS5, the Quattro concept features a shortened wheelbase, lower roofline and a sub-3,000 pound curb weight. The original Ur-Quattro weighed in under 3,000 pounds and featured a turbocharged five-cylinder engine paired with a five-speed manual. Keeping in line with that spirit, the Quattro concept ditches the V8 and dual-clutch transmission from the RS5 in favor of a turbocharged inline five-cylinder engine and six-speed manual gearbox.
Power output for the Quattro concept is rated at 408 horsepower and 354 pound-feet of torque. All that energy is put to the ground through Audi’s famous quattro torque-vectoring all-wheel-drive system, which in this case is setup with a 40:60 rear-biased torque split. The weight savings mixed with the power output create a vehicle with a power-weight ratio on par with that of the Audi R8 5.2 FSI.
