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.

2017 Bentley Mulsanne defines the latest in handcrafted luxury

It takes 144 craftsmen roughly 399 hours to build a Bentley Mulsanne. In today's world of automation and just-in-time parts delivery, such statistics sound ridiculous. But this old-school approach to vehicle assembly earns this beast its status as Bentley's flagship. It takes about a third of that time to assemble a Continental GT, for instance, which is one reason the Mulsanne is so expensive. It's also why Bentley moves more than five Continental models for every Mulsanne it sells. Bentley has a brand-new crown jewel coming soon to dealerships as a 2017 model, and it will debut next week at the 2016 Geneva Motor Show. An Extended Wheelbase version joins the base Mulsanne and the Speed, pushing the lineup to three for the first time. Although Bentley officials take pride in the fact they are the largest producer of 12-cylinder engines in the world, the Mulsanne continues to soldier forth with the long-serving 6.75-liter V8. While this L-Series engine traces its roots all the way back to 1959, as evidenced by its cam-in-block overhead-valve design, it's been fully modernized with electronic controls and twin turbochargers. The result is 505 horsepower and 752 pound-feet of torque (or 530 hp and 811 lb-ft in the Speed), routed through a ZF eight-speed automatic transmission to the rear wheels. This is the same engine that has powered flagship Bentleys since 2010, and it's effortlessly capable of pushing the Mulsanne from 0-60 in 5.1 seconds and all the way up to a top speed of 184 miles per hour. The upgraded Mulsanne Speed improves those figures to 4.8 seconds and 190 mph. That's plenty of performance for this kind of vehicle, weighing as it does nearly 6,000 pounds. With that kind of power and heft, a solid chassis is a must. Active engine mounts join new suspension bushings for 2017, and the air suspension system has been updated. Continuous Damping Control and a Drive Dynamics Control System with three factory and one custom setting are standard. Also new are tires codeveloped with Dunlop that have foam-filled cavities to reduce interior cabin noise. Where the styling of the outgoing Mulsanne is smooth and stately, the new one is more angular and modern. At the front, the traditional upright grille remains, but it's over three inches wider than before, and is slatted with vertical vanes in polished stainless steel that are meant to recall Bentley classics from the 1930s.

Bentley recalls nearly 2,000 examples of the Bentayga over fire risk

Bentley is voluntarily recalling 1,892 examples of the Bentayga in America to replace a fuel line that could leak and cause a fire. The affected SUVs were manufactured between July 26, 2018, and January 15, 2020. Documents submitted to the National Highway Traffic Safety Administration (NHTSA) explain the SUVs included in the recall are fitted with a quick fuel line connector that can leak if it's exposed to extremely high temperatures in the engine bay. Fuel and heat don't go together well, unless they meet in a cylinder, so the leak could start a fire. Bentley noted motorists might smell fuel in the engine bay if the connector leaks, but Autoblog learned from a company spokesperson that it's not aware of accidents, injuries, or even damage related to the problem. The spokesperson stressed the recall only applies to the Bentayga V8; it doesn't include the W12 model or the plug-in hybrid. Only about 0.2% of the SUVs being recalled have this defect, according to the firm. Bentley explained it noticed the problem in 2018, when a customer complained the SUV smelled like gasoline. Technicians identified the cause of the problem as material softening due to elevated temperatures in the engine bay, and engineers began working on a fix and testing it in real-world conditions. The redesigned part notably faces away from the hot side of the engine, according to a recall bulletin published by the NHTSA. Owners of affected cars will be notified in the coming weeks, and they'll need to bring their Bentayga to the nearest dealer to have the fuel line and its quick connector replaced. It's a job that takes approximately one hour. The average Bentley customer owns eight cars, so at least Bentayga owners won't be stuck using Uber.
