  • Volkswagen updates their W12 turbo motor with direct injection - 6.0 liter 600 horsepower 664 lb-ft of torque twin turbo W12 6.0 TSI monster on the way

    The Volkswagen Auto Group will be updating their unique W12 motor this year. The application in which it is most known is in the Bentley Continental GT of course. The issue with the venerable twin turbo W12 in that application is that the Continental GT is offered with the Audi 4.0 TFSI V8 which offers essentially the same performance but with greater efficiency.


    The W12 has been used in turbocharged and naturally aspirated applications throughout the VW group. The disappointing Phaeton uses a naturally aspirated version and the current Audi A8 W12 uses a naturally aspirated version with direct injection. Presumably the new Phaeton will get this new turbo variant and the A8 will also be updated with it.

    The previous turbocharged version has the same displacement as this updated model but without direct injection. That is the main change here and we will have to wait and see if the compression ratio is changed from 9.0:1. It likely will be along with turbos and boost pressure which explains the increase from the base 582 horsepower and 531 lb-ft of torque.

    The Continental GT Speed makes 626 horsepower and 605 lb-ft of torque. Expect this new engine to surpass the power output as it is already easily eclipsing the torque figure. VW is getting massive torque out of the new motor.

    What is interesting is that Bentley’s TMPI multi-point injection is used in conjunction with the TSI direct injection system. VAG uses port and direct fuel injection in the new Huracan V10 5.2 as well.

    This will be a beast of a motor.




    Volkswagen at the 36th International Vienna Motor Symposium
    Dr. Heinz-Jakob Neußer: "The car of the future will continue to fascinate people"

    - CO2 reduction, electromobility and digitalisation are the greatest challenges facing the automotive industry
    - The future of the internal combustion engine will be characterised by high rpm diesel and high-performance three-cylinder TSI engines
    - Laser roughening – innovative coating process in large-scale production
    - New 6.0 W12 TSI with 447 kW (608 PS) – performance and refinement
    - New generation of EU6 TDI engines for light-duty vehicles

    Dr. Heinz-Jakob Neußer, Member of the Board of Management for the Volkswagen brand with responsibility for Development and Volkswagen Group Head of Powertrain Development, concluded this year's International Vienna Motor Symposium by providing an outlook of the future of mobility and innovative technologies. The biggest challenges facing the industry are reducing CO2 emissions, electromobility and digitalisation.

    At the symposium, Friedrich Eichler, Head of Powertrain Development for the Volkswagen brand, also presented the new 6.0 W12 TSI. The new EU6 TDI engine family for light-duty vehicles was presented by Jörn Kahrstedt, Head of Diesel Engine Development for the Volkswagen brand.

    In his concluding presentation, Dr. Neußer stated that the industry had changed more rapidly and more extensively in the last few years than in the preceding decades. However, environmentally friendly mobility remains the key topic for the automotive industry. "Climate protection is an integral part of our responsibility towards people and society. Moreover, customers demand models with reduced consumption and lower emissions and politics also makes high demands on the automotive industry", Dr. Neußer continued.

    The wide range of powertrains within the Volkswagen Group – ranging from petrol and diesel engines to natural gas vehicles, plug-in hybrids, purely electric cars and potentially even fuel cell cars – shows the Group's enormous innovative strength. The Management Board Member in charge of development emphasised that: "The optimisation of the internal combustion engine is still an important field of innovation. High-efficiency TDI and TSI/TFSI engines – ideally in combination with DSG – will remain indispensable for the foreseeable future. The reduction of CO2 emissions from internal combustion engines is pure high-tech nowadays. Examples of this are our high rpm diesel as well as the high-performance three-cylinder TSI engine."

    Dr. Neußer highlighted the fact that the high rpm diesel points the way to the future of the internal combustion engine in many respects. With high-efficiency combustion methods, innovative thermal management, maximal charging thanks to e-boosters as well as new materials and coatings, these state-of-the-art TDI engines are already capable of achieving a power output of well over 100 kW per litre of displacement.

    In the field of petrol engines, Dr. Neußer offered a glance at the high-performance three-cylinder TSI based on the EA211 engine. With the genes of the Polo WRC's rally engine, this power unit is capable of generating 272 PS and 270 Nm of torque from just one litre of displacement thanks to a monoscroll turbocharger and e-booster. "A nice example of just how much potential combustion engines still have in them", according to Dr. Neußer.

    Dr. Neußer also gave a peek at "laser roughening". This coating technique, which the Volkswagen Group will use in large-scale production in future, contributes significantly to reducing friction in the engine and to boosting performance. Dr. Neußer pointed out that this is an important innovation in manufacturing technology, since laser roughening not only reduces tool wear to zero, but also achieves consistent results and can be used for all materials.

    Dr. Neußer sees digitalisation as the greatest challenge, because infotainment, assistance systems and networking have come to be at least as important to many customers as the engine performance. "The Golf R Touch concept car has everything on board that characterises the cockpit of the future: full connectivity thanks to the integration of apps, smartphones, tablets and smart watches, as well as large touchscreens and, last but not least, gesture control, which opens the sunroof at a wave of the hand. Over and above this, we are also pushing the envelope when it comes to automatic or piloted driving and are working on new business models and a range of digital services relating to our cars. So I am sure that the car of the future will continue to fascinate people just as much as it ever has."

    A few hours earlier, Volkswagen had already presented its latest generations of engines at the International Vienna Motor Symposium, which is held annually by the Austrian Society of Automotive Engineers (ÖVK), chaired by professor H.P. Lenz from the Vienna University of Technology: the new W12 TSI, as one of the most demanding premium engines in the world as well as the new 2.0 litre TDI EU6 diesel engine for light-duty vehicles. The talk about the new twelve-cylinder engine was given by Friedrich Eichler, Head of Powertrain Development for the Volkswagen brand, while the new family of diesel engines was presented by Jörn Kahrstedt, Head of Diesel Engine Development for the Volkswagen brand.

    The new 6.0 litre W12TSI for the Volkswagen Group's premium models

    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.

      I'm excited for this. Will definitely be the "base" engine, Speed models will hopefully get 650+ hp and 700+ torque. They need to justify their existence compared to the V8, and quite frankly there's no reason a 6 liter, 12 cylinder twin turbo engine can't be at the top of the food chain. The W12 sounds pretty nice too, much more "Bentley" than the V8.

      Now if only Mercedes would figure out a new V12. How about take the M177...and then add half of another M177 to it. Boom. 6 liters, 12 cylinders, twin turbos, hot vee. Should be good for 700+ hp and torque to start with, no problem. And it will rev. Where's my check.

      Exactly, the 4.0 V8 was offering the same performance with better handling and better MPG. The W12 became redundant.

      Never going to happen. I'm surprised the even keep the M279 in production.

      If they don't do it they're shooting themselves in the foot...there's a ton of loyal V12 customers, according to what I've heard. It would blow away the M157, and it would be much smoother/sound much better and probably even get the same/better gas mileage. I know chances are slim but I can't honestly see why they *shouldn't* do it. It's not a volume engine anyway, they're spending a lot to keep the stupid 279 in production as-is. Might as well spend that money to get a much better engine. But hey, what do I know. I guess I'm just too used to the idea that the big sedans should have 12 cylinders.

      I mean in theory it would be amazing but I doubt the V12 customers care about the performance as much as the idea of having a V12. The M279 already fits that bill.

      It's possible. They're all old geriatrics anyway...mostly. The first W221 S65 I ever saw, back during Christmas '05, was literally full of 4 of the oldest, frailest people I've ever seen still alive on this planet. I'll never forget that as long as I live. Funny and sad.

      Your talk of Mercedes taking the 177 and adding another half of a 177 reminded me of a project I saw a while back. I'm sure I can find it if I look. Sticky, I'll post it up when I do come across the story.
