Under the new sheet metal will be an extended version of the modular platform used in the A4, but expect to see more exotic materials such as aluminum and magnesium employed to help save weight and improve dynamics. The engine lineup will likely mirror the current range, starting with a 2.8L petrol V6 and topping out 4.2L V8 FSI and possibly the carmaker’s new 6.0L V12 TDI. There will also be more supercharged units as well as increased application of Audi’s latest valve-lift system. The 6.0L W12 engine is reportedly being phased out due to its high costs and emissions.
The base model will remain FWD but AWD variants will feature the latest quattro torque vectoring systems, which distribute drive individually between each axle and between the rear wheels for improved traction and stability.
