New 6.0 TFSI W12 Engine Revealed at Vienna Motor Symposium
by Volkswagen AG on 11 May 2015 in Audi NewsAs with many things in life, what was once a rather nerdy thing like an annual symposium about engines is now becoming mainstream cool. In addition to the latest Miller Cycle inspired 2.0 TFSI shared by Audi last week, Volkswagen also revealed the latest evolution of the W12 now with TFSI turbocharged direct injection and bound for the next A8.
If you’re versed in the W12 usage at the Volkswagen Group, then you know that the Audi A8 has only ever featured the normally aspirated version of the unique 12-cylinder engine. Bentley Continental models have featured more powerful twin turbo versions since their inception, though more restrictive emissions rules appear to be forcing forced induction into all W12 applications. This could be good news for Audi’s A8.
In the below press release from Volkswagen, the engine is described as the 6.0-liter W12 TSI. TSI is Volkswagen marketing speak for turbocharged direct injection, something Audi refers to as TFSI. In as much, we’ve changed the nomenclature above in our title and also in this story’s tags… this being an Audi-focused website.

Based on the W12 concept, the Volkswagen Group has deployed top-of-the-range engines that have demonstrated their perfection in terms of performance and comfort in the premium models made by the Volkswagen, Audi and Bentley brands in an impressive manner for some 13 years now. The next generation W12 TSI presented at this year’s Motor Symposium makes the Volkswagen Group’s cutting edge engine one of the most fascinating power units with the highest technology density in the world.
For example, as part of the improvements and new developments, two combustion methods that have to date been used in parallel – Audi’s FSI direct injection and Bentley’s TMPI multi-point injection – were combined, together with other new or optimised systems and components, to form the successful TSI process. The scope of development also included 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. Adaptive engine suspension with hydraulic basic damping, which uses electromagnetic actuators to counteract vibrations induced by the engine with phase-shifted counter-vibrations, contributes to the premium-quality driving comfort.
The technological elements used make the new W12 TSI the most economical twelve-cylinder engine in the luxury car segment. CO2 emissions of less than 250 g/km in the New European Driving Cycle (NEDC) – at a power of 447 kW/608 PS (6,000 rpm) and a maximum torque of 900 Nm (1,500 – 4,500 rpm) – demonstrate impressively how efficiency and performance of the highest standard are combined in this engine. Depending on the vehicle model, the 6.0 l twelve-cylinder engine delivers acceleration values of 0 to 100 km/h in less than four seconds and top speeds of over 300 km/h.
