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:    

The next Bentley Mulsanne could go all-electric

How many Bentleys are sold in China, anyway?* That's a question worth asking after the company said it will consider switching the powertrain of its uber-luxe sedan Mulsanne to all-electric from its current gas-guzzling V8 setup. Such a switch would be in the name of adhering to stricter greenhouse-gas emissions limits, especially in countries like China. Bentley executive Hans Holzgartner told Autocar that the company may soon have problems selling a V8-powered Mulsanne in China because government regulators are attempting to push for more zero-emissions vehicles to combat smog problems in the country's largest cities. Oddly, Holzgartner said an electric powertrain is "better suited" to heavier luxury cars than lighter sports cars because of an electric motor's smooth, instant delivery of torque. With the Mulsanne already priced north of $300,000 in the US, passing on the costs of such a huge battery pack will probably be less of an issue than for more typically-priced models. Of course, there would be a ton (almost literally) of battery cells involved. The Mulsanne tips the scales at almost 6,000 pounds, or almost twice the weight of a Nissan Leaf and about 25 percent more than a Tesla Model S. For those curious how the one-percenters live, take a look at Autoblog's recent drive of a Mulsanne Speed. Since this is just being studied at this point, it's possible the next Mulsanne could get a battery-electric or plug-in hybrid version for certain markets, while others would retain a gas engine or offer a choice. Assuming it keeps the gas option, the next Mulsanne will reportedly to switch to a twelve-cylinder engine, likely a version of the Volkswagen Group's W12. As for green cred, let's just say the Mulsanne's couldn't be much worse. Earlier this year, the Mulsanne showed up on the American Council for an Energy-Efficient Economy's (ACEEE) annual list of "meanest" vehicles when it came to environmental sustainability. The Bentley was rated the fourth-meanest vehicle sold in the US, following the Mercedes-Benz G65 AMG, the Chevrolet G2500 Express/GMC Savana, and the Mercedes-Benz G63 AMG. The EPA rates the Mulsanne's fuel efficiency at an absolutely gasoline-swilling 13 miles per gallon combined. * If you're curious, Bentley sold 1,615 cars in China last year.

VW Group plan puts Porsche in charge of a 'super-premium' division

An Automobile report looks into what's happening on the organizational and technical sides of the Volkswagen Group, and what those changes could mean for the premium brands. The wide-angle view is that Porsche appears to have been anointed to "coordinate the future activities" at Audi, Bentley, Bugatti and Lamborghini. Audi would cede Lamborghini guardianship to Stuttgart, and Ducati — via a new concern called Ducati Enterprises — would become the shepherd for VW's other Italian investments. Executives target Jan. 1, 2019, to complete the reshuffle. VW wants to save a boodle by tying up four of its five top-tier brands, and putting the one with the highest ROI in charge. Porsche, within its own house, wants to reduce expenditures by $2.3 billion per year over for four years, the savings already earmarked for improving internal processes like R&D and production. Having Porsche share those gains as well as lead development of platforms, components and future-tech strategies for the sister sports car brands could benefit everyone. In the near-term, the brands have their own plans: Bugatti CEO Stephan Winkelmann is said to want a Chiron Superleggera, a roofless and "completely reskinned" Chiron Aperta, and a track-only Chiron SS. The Superleggera could take the Chiron Sport's and Divo's Jenny Craig routines even further. The Aperta seems a natural successor to the Veyron Grand Sport, a natural evolution of the recently introduced Sky View roof, and a reskin might include numerous Divo cues. It's also said Bugatti's considering "an all-electric high-end model" in conjunction with Porsche, Rimac, and Dallara, but name one supercar or hypercar manufacturer that isn't considering a lightning-fast EV. Lamborghini, deep into work on follow-ups for the Huracan and Aventador, might get a bit of a bump with the new plan. The carbon "monofuselage" for the next V12 flagship is said to be too far developed and too complex to scrap. It puts two electric motors on the front axle, batteries in the middle, and a naturally aspirated V12 with around 770 horsepower plus another e-motor with 402 horsepower in back. The Huracan is said to get a version of the same carbon architecture at the moment, but the corporate reorganization might press pause on it. Automobile says options include continuing the Huracan/ Audi R8 twinning, but that depends on Audi saying "Ja" to a third-gen R8 with Lamborghini bones.
