Volkswagen has unveiled a new 6.0 litre W12 TSI at this year’s Motor Symposium for the Volkswagen Group’s premium models.
W12 engines have been used in the premium models made by the Volkswagen, Audi and Bentley brands for some 13 years now.
The next generation W12 TSI combines two combustion methods that have to date been used in parallel – Audi’s FSI direct injection and Bentley’s TMPI multi-point injection, along with other new or optimised systems and components, to form the successful TSI process.
Some of the notable highlights include cylinder bores with APS coating, an oil circuit suitable for off-road use with a switchable oil pump, a cooling system with integrated temperature management, dual fuel injection with high pressure direct and low pressure manifold injection, twin-scroll biturbo charging, individual cylinder bank deactivation (on the left in the direction of travel), engine management with two controllers as well as a start/stop system that reduces fuel consumption and emissions.
As a result the new W12 engine produces 600bhp and 900Nm of torque, while CO2 emissions are less than 250g/km.
Depending on the vehicle model, the 6.0-litre twelve-cylinder engine takes an unnamed model from 0-62mph in less than four seconds on to a top speed of over 186mph.
The first model expected to use the new engine is the upcoming Bentley Bentayga SUV.
