Audi Allroad Shooting Brake: 149mpgJanuary 15, 2014
The Audi Allroad Shooting Brake ‘e-tron quattro’ concept , capable of 149mpg and 45g/km CO2, has been shown at the Detroit Motor Show.
The Allroad Shooting Brake has a plug-in hybrid drive which delivers 408 PS of system power and system torque of 650 Nm. The show car accelerates from 0 to 62mph in 4.6 seconds and is capable of reaching an electronically limited top speed of 155mph.
Fuel consumption is 148.7mpg according to the ECE standard, which equates to CO2 emissions of 45g/km. A total driving range of up to 510 miles is achievable.
The 2.0 TFSI in the Audi Allroad Shooting Brake delivers 292 PS of power and generates 380 Nm of torque, and operates together with a disc-shaped electric motor via a decoupling clutch. The electric motor outputs 40 kW of power and 270 Nm of torque and is integrated in the six-speed e-S tronic. The dual clutch transmission sends torque to the front wheels.
A second electric motor, which is separate from this drive unit, is mounted to the rear axle. It supplies propulsive power at low and moderate vehicle speeds with its maximum power of 85 kW and 270 Nm of torque. It can also be operated in tandem with the motor and engine at the front axle if the hybrid management system decides that the car needs all-wheel drive. In such situations, e.g. on a slippery road or in light off-road conditions, this essentially makes the Audi Allroad Shooting Brake an e-tron quattro.
Located just forward of the rear axle is a lithium-ion battery which can provide 31 miles of all-electric driving.
Drive select management offers three driving modes. EV mode means that the front drive unit is inactive, and the electric motor at the rear axle can rapidly accelerate the car to a top speed of 81mph.
In Hybrid mode, the drive sources work together as necessary. In many situations the electric motor in front acts as a generator – driven by the engine, it charges the battery, and this extends the car’s effective electric driving range.
In Sport mode the car’s full system power is available. The electric motor at the rear axle works together with the 2.0 TFSI in a boost mode, in which both drive units output propulsive power.
