Volkswagen will take on the likes of the Mercedes-Benz S-class, Lexus LS430, BMW 7-series and Jaguar XJ8 when it launches its five metre long, 1.9 metre wide 'Project D1' luxury saloon next year. The car will debut at the Geneva motor show in March with two petrol engines - a 3.2-litre 241bhp V6 and a 420bhp six-litre W12. Five engines will eventually be available, including a 313bhp five-litre V10 turbodiesel developing 750Nm of torque which will be offered with a six-speed automatic gearbox.
