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.

VW, Fiat, Mercedes could be CNG winners in Europe

Fiat ads in the US try to play up the exotic, sexy side of Italian culture. On the home front in Italy, however, passenger-vehicle sales are marked by something less edgy and quite a bit more practical: the growth of compressed-natural-gas (CNG) powered car sales. In fact, Italy is leading a group of European countries where CNG sales are on the upswing and may be benefiting automakers like VW, Fiat and Mercedes-Benz, according to Automotive News. VW started sales of its Golf TGI natural-gas vehicle this year – the company's fourth in Europe – while Mercedes-Benz added a natural-gas B-class model. Fiat accounts for about 50 percent of CNG vehicles sold on the continent. In all, Europe's CNG sales through September totaled about 67,000, up seven percent from a year earlier, Automotive News Europe says, citing research firm JATO Dynamics. And the number of CNG vehicles on Europe's roads could jump tenfold within the next decade. The draw is a combination of lower refueling prices and a CNG drivetrain that typically emits less CO2 than diesel vehicles. As for Italy, about five percent of new-vehicle sales are CNG. To put that into perspective, hybrids, battery-electric vehicles, plug-in hybrids and diesels combined to account for about 4.2 percent of US vehicle sales last year.
