VW announces reworked 6.0 W12 TSI engine

Nobody makes more engines with a dozen cylinders than the Volkswagen Group. They're W12s, of course, owing to the novel shape of their cylinder banks. Now the German industrial giant has announced a comprehensively reworked version of that engine at the same Vienna Motor Symposium where it presented its new 2.0-liter turbo four. The new W12 retains the same arrangement and the same 6.0-liter displacement, but updates it all with the latest powertrain tech. In place of Audi's FSI direct injection and Bentley's TMPI multi-point injection, the engine has adopted a new TSI system. It's also got a pair of new twin-scroll turbochargers, APS-coated cylinders, a new cooling system, active engine mounts, cylinder deactivation, and a stop/start system. And – crucially for application in the upcoming Bentayga – it has an oil circuit designed for off-road use. The revised package now produces 600 horsepower and 664 pound-feet of torque. Considerably more than the 567 hp and 516 lb-ft offered in the Bentley Continental GT W12, but less than the GT Speed, which we suspect will get an even more powerful version of this new engine. It's also more powerful than even the top version of Audi and Bentley's 4.0-liter twin-turbo V8, to make the W12 a more compelling option. Of course that's just as far as the Continental GT is concerned. The W12 has also found use in the Continental GTC and Flying Spur, as well as the Volkswagen Phaeton and Audi A8, and could find further applications under the Flying B emblem and elsewhere in the future. VW says that in the right application (say, in the production version of the Bentley EXP 10 Speed 6 concept, for example), the new twelve-pot could deliver 0-62 times of under four seconds and a top speed in excess of 186 miles per hour. 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.

Xcar asks why the W in the Bentley Continental GT

There aren't a lot of automakers producing V12 engines these days: There's BMW and Mercedes, of course, and the Rolls-Royces and Paganis they power. There's Ferrari, Lamborghini and Aston Martin. But the largest producer of twelve-cylinder engines doesn't make them in a V. That'd be Bentley, and it produces more dozen-piston engines than anyone else, but arranges them in a W configuration. It's a compelling story of innovation, one as interesting as the history of the marque itself. And Xcar tells the tale in its latest video installment, tracing it back to the development of the compact VR6 engine and the autocratic mastermind at the helm of the Volkswagen Group who made the W12 a reality. By this point it would be all too easy to consign the W12 to the dustbin of history as the smaller, more efficient and nearly as powerful V8 has slotted in below to push the W12 to the margins of relevance. But it's still the more refined option, and the more innovative one. Little wonder it's the only type of twelve-cylinder engine (the Aventador's notwithstanding) that the Volkswagen Group still makes.

Bentley Bentayga may spawn sportier fastback version

In the past few years, Bentley has shown us two different conceptions about what its future might look like in: the SUV that started life as the EXP 9 F concept and has now entered production as the Bentayga, and the EXP 10 Speed 6 concept that previews a future sports coupe from the stoic British marque. The next step is an SUV that combines a little of each of them. According to Automotive News, engineers and designers in Crewe are currently laying the groundwork for a crossover that would blend the tall form of the Bentayga with the roofline of the Speed 6. The result would be similar in form, we'd imagine, to the likes of the BMW X6 and Mercedes GLE Coupe, only even further upscale. We wouldn't be surprised to see more changes than the roofline and tail section, either, with a sportier front end and more avant-garde headlights (like those we saw on the Speed 6 concept) giving it a sportier, less stodgy appearance all around – and maybe, just maybe, a different nameplate. CEO Wolfgang Durheimer wants to get the fastbacked Bentayga variant ready by 2018 or 2019 – right around the time that Rolls-Royce, Aston Martin, Maserati, and Lamborghini will be rolling out their debut crossovers. By that time, Bentley will have already have had the Bentayga on the market for two or three years, and wants to be ready to fight off the onslaught with something fresh. "Imagine the EXP 10 as an SUV. It doesn't look 'old Bentley, Durheimer told AN. "The Bentayga doesn't stop us from dreaming and looking down the road. The more success we have with it, the more we can take the best of it and run with it." Proceeding with the project will require Durheimer to get approval from the Volkswagen Group head office in Wolfsburg, but the business case seems like a slam dunk. The model would help Bentley (and VW) further capitalize on the $1 billion it already spent developing the Bentayga, following a successful business model laid out by rival BMW and which Germany's other automakers are quickly learning to emulate. This wouldn't be the first time he'd be seeking approval from Matthias Muller on such a project, either. Durheimer successfully ushered the Cayenne into production when he was head of R&D at Porsche and Muller was the brand's CEO.
