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 builds its final 6.75-liter V8, ending a 61-year production run

Bentley has just finished its very last 6.75-liter V8. While engines come and go, this is significant because Bentley has been building this engine, known as the L-series, for 61 years. This final engine will go in the 30th and last Bentley Mulsanne, a 6.75 Edition by Mulliner, marking the end of the flagship sedan. The L-series engine was first introduced in 1959, and according to Bentley, it was developed in order to develop more power than its existing inline-six without adding weight or taking up more space. The engine in fact weighed 30 pounds less than the six-cylinder, and it made about 180 horsepower. That original engine "only" had 6.2-liters of displacement, and it wasn't until 1971 that it would reach 6.75 liters thanks to increased stroke. This final version of the engine is significantly different from its fuel injection to its twin-turbochargers, but is based on the same design. And with 530 horsepower and 811 pound-feet of torque, it's the most powerful iteration of the engine. At 61 years, the Bentley engine is arguably the V8 with the longest production run. While the first-generation Chevy small block V8 was introduced earlier for the 1955 model year and is still built in crate engine form, GM stopped using it in production cars in 2002. Far fewer Bentley engines were built, though, with a total over 36,000, as opposed to the millions of Chevy small blocks in the world. Of course, volume is sort of the antithesis of what makes a Bentley a Bentley. With the 6.75-liter engine out of production, all of Bentley's engines are derived from VW Group engines, from its W12 to the plug-in hybrid V6. Related Video:    

Bentley considering chopping new Bentayga into a crossover coupe

Like it or not, crossover coupes are gaining traction. BMW lead the march with the X6 and has since followed up with the X4, rival Mercedes has already showcased its new GLE Coupe, and Audi is expected to be following suit as well. So who's next? According to Top Gear, that'd be Bentley. The British luxury automaker is (like Jaguar and Maserati) preparing to launch its first SUV in the form of the upcoming new Bentayga. But it isn't likely to stop there. After speaking with Bentley CEO Wolfgang Durheimer, who pointed towards the growth in the luxury crossover segment at the expense of coupes, convertibles and sedans, Top Gear is convinced that the Flying B marque is weighing the possibility of a slant-backed coupe version. If BMW's experience is anything to go by, reconfiguring the roof and styling of the Bentayga to give it a more rakish profile would be a relatively low-cost, straightforward way to give Crewe another crossover model to offer. But by the same token, we wouldn't expect it to lose any doors in the process as that same Bavarian rival did with the Mini Paceman. With the Bentayga set to debut next year, it may not be until 2019 that the coupe version would arrive. That's if it's given the green light in the first place, with Bentley expected to decide "within the next year and a half," according to TG. What isn't clear at the moment, however, is whether the Bentayga crossover would stand in place of the smaller crossover Bentley was said to be considering, or the four-door coupe or sports car projects that were said to be on the table as well.
