Audi A8 4.2
Audi has unveiled details of a partnership with Bang & Olufsen to develop in-car audio systems exclusively for its range-topping A8 series. It has also introduced a twin-turbo 4.2-litre diesel. This is the most powerful engine ever fitted to a production car, yet it’s economical enough to haul the vehicle from Cannes to Madrid without refuelling (providing you don’t exploit the car’s high-end performance).
