Audi’s debuts at this year’s Detroit Motor Show are based on existing models, but they are hugely interesting nonetheless. We have the 2014 RS7, the ultimate version of the A7 Sportback with a 0 to 60 time of under 4 second, and the 2014 SQ5, a high-performance crossover vehicle that for the American  market boasts a powerful petrol engine.

The RS7 is powered by a 412 kW (560 hp) available between 5,700 and 6,700 rpm. A constant 700 Nm (516.29 lb-ft) of torque are available between 1,750 and 5,500 rpm. The Audi RS7 Sportback sprints from 0 to 100 km/h (62.14 mph) in just 3.9 seconds. Audi limits the top speed in the standard configuration to 250 km/h (155.34 mph). Top speed with the optional dynamic package is 280 km/h (173.98 mph) and 305 km/h (189.52 mph) with the dynamic package plus.

The new Audi SQ5 is powered by a free-revving, supercharged, three-liter V6 engine with a displacement of 2,995 cc. Its compressor sits in the 90-degree V of the cylinder banks and is belt-driven by the crankshaft. It produces 260 kW (354 hp) and 470 Nm (346.65 lb-ft) of torque, giving the car a zero to 100 km/h (0-62 mph) in 5.3 seconds on its way to a top speed of 250 km/h (155 mph).
