Audi shows off an e-tron quattro in Detroit

Audi’s all-road shooting brake show car, which is on display at this week’s North American International Auto Show (NAIAS) in Detroit, highlights what the company calls “a new form of quattro drive – the e-tron quattro.”

The compact crossover has a plug-in hybrid drivetrain that delivers 300 kW (408 hp) of system power and system torque of 650 Nm (479 lb-ft). It launches itself from 0-62 in 4.6 seconds, and has an electronically limited top speed of 155 mph. Audi estimates fuel economy at around 124 mpg.

The 2.0 TFSI gas engine is a transverse-mounted two-liter four-cylinder with a large turbocharger, and cranks out 215 kW (292 hp) of power and 380 Nm (280 lb-ft) of torque. This operates together with a disc-shaped 40 kW electric motor via a decoupling clutch. A six-speed dual-clutch transmission sends torque to the front wheels.

A second electric motor, mounted to the rear axle, supplies power at low and moderate vehicle speeds with maximum power of 85 kW and 270 Nm (199.14 lb-ft) of torque. It can also be operated in tandem with the motor and engine at the front axle for all-wheel drive in slippery road or light off-road conditions.

The liquid-cooled lithium-ion battery consists of eight modules, and has an energy capacity of 8.8 kWh, which is enough for 50 km (31 miles) of all-electric driving.

There are three driving modes. In EV mode, the front drive unit is inactive, and the rear electric motor can accelerate the two-door car to a top speed of 81 mph. In Hybrid mode, the drive sources work together in various ways for maximum efficiency. In Sport mode, the car’s full system power is available.
