Audi e-tron Allroad 400 HP plug-in hybrid concept officially revealed

The Audi Allroad Shooting Brake has been revealed ahead of its motor show debut in Detroit.

The show car’s engine is a 2.0-litre petrol with 288bhp and 280lb ft of torque, which drives the front axle. This is supplemented by a 54bhp electric motor that’s integrated within the six-speed automatic gearbox.

The second motor is mounted to the rear axle, and produces 114bhp and 199lb ft of torque. It can either power the car on its own – in rear-wheel-drive pure electric mode – or combine with the powertrain over the front axle to turn the Allroad Shooting Brake into a four-wheel-drive hybrid.

In pure electric drive mode, the rear motor can propel the car up to 80mph, while the battery can power the car for 31 miles. A hybrid mode lets the engine and motors work together as efficiently as possible, permitting the front motor to top up the lithium-ion battery when required.

This generator function means that the pure electric range can be replenished, which would allow for multiple stints of all-electric driving on a long enough journey. The car has a range of 510 miles using the most efficient settings. Average fuel economy is a claimed 148.7mpg, while CO2 emissions are just 45g/km.

There are ‘Hold’ and ‘Charge’ settings within Audi’s redesigned MMI infotainment system that allows the driver to choose how the battery’s charge is managed. Hold mode will keep the battery at its current state of charge, while Charge mode will replenish it until it is full.

The final drive mode is Sport, which combines the petrol engine and both motors to give a total power output of 402bhp with 479lb ft of torque. In this set-up, the car has a 0-62mph time of 4.6 seconds, and a limited top speed of 155mph.
