Audi Will Abandon Traditional AWD, Replace with e-Quattro in Some Next-Gen Cars
Audi is working on an electric all-wheel-drive system for upcoming vehicle generations, a company source has confirmed to us. Audi previously has shown an A5 prototype with an electric motor driving the rear axle, with power distributed through Audi’s sports differential in order to enhance the vehicle’s handling characteristics by torque vectoring.
By driving the rear axle with a separate electric motor, the e-Quattro system eliminates the need for a mechanical connection between the internal-combustion engine and the rear axle. This means more packaging flexibility. But that flexibility comes at a cost, and that cost is weight. The need for batteries and the electric motor could easily offset the savings in the drivetrain.
- Comparison Test: 2012 BMW 328i vs. 2012 Audi A4 2.0T, 2012 Infiniti G25, 2012 Mercedes-Benz C250 Sport, 2012 Volvo S60 T6 AWD
- First Drive: 2013 Audi Allroad
- Comparison Test: 2012 Audi A7 3.0T Quattro vs. 2013 BMW 640i Gran Coupe
The e-Quattro system would fully replace conventional all-wheel drive in vehicle lines where it is offered, but Audi will offer both systems for a lengthy period of time. The compact, MQB-based vehicles like the A3 will retain conventional all-wheel drive, as will the heavier SUV models. The most likely candidates for e-Quattro are the vehicles on the second generation of Audi’s MLB platform, such as the next-generation A4 and A6. Expect to see e-Quattro in two to three years.
