Bentley to retire aging 6.75-liter V8 with current Mulsanne

The massive 6.75-liter V8 in the Bentley Mulsanne is one of the oldest engines still in production. But it may not be around for much longer. According to Car and Driver, Bentley intends to finally put the big old pushrod V8 to pasture once the current Mulsanne is phased out, thus putting an end to a saga that goes back some 57 years. Powerful as it may be, ever-stricter exhaust emissions and fuel-consumption regulations will see that the L Series V8, originally introduced way back in 1957, doesn't stay in production forever. Whenever the Mulsanne is replaced, it will reportedly get a brand-new twelve-cylinder engine. Bentley is currently the world's largest producer of dozen-pot powerplants. Production of the British automaker's 6.0-liter twin-turbo W12 far outpaces anything from Rolls-Royce, Mercedes-Benz, BMW, Ferrari, or Lamborghini. Over the decades since its introduction, Bentley's long-serving V8 has gone from making an "adequate" amount of power and torque to an impressive 530 horsepower and a positively massive 811 pound-feet (with the help of a couple of turbochargers). Its eventual discontinuation wouldn't be the first attempt on the life of the 6.75-liter engine. When BMW briefly took control of both Rolls and Bentley, it replaced the big engine by a smaller 4.4-liter V8. Customer demand led Bentley to bring the old engine back. It will likely be some time before we get details of Bentley's next powerplant. Models like the Mulsanne and Rolls-Royce Phantom tend to stick around for a long time, and the latest version of Bentley's flagship was just released earlier this year. 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.

Bentley Azure could return for limited edition

Once upon a time, Bentley had two convertibles in its lineup – there was the Continental GTC, which you can still enjoy today, and the Azure, which you can't. The bigger offering, based on the Arnage sedan, went out of production several years back, much to the disappointment of those with ostentatious tastes and bottomless pockets. But if Wolfgang Durheimer has his way, the 20-plus-year-old nameplate could return in a limited run based on the Mulsanne. The last Azure demanded ridiculous wealth to purchase, but this new model would be on an entirely different level. According to Car and Driver, Durheimer said a reborn Azure "would be built in [a batch of] 20 units and sold to absolute connoisseurs at a very high price." He stopped short of actually confirming the vehicle or its cost, but that hasn't stopped Car and Driver from suggesting a price of $1 to $1.5 million per vehicle. The timing here is fascinating, largely because Bentley's arch-rival, Rolls-Royce, is preparing to phase out its Phantom Drophead Coupe – the Mulsanne Convertible's most natural rival – due to slow sales. Whatever this limited-edition vehicle is called, it'd be all on its own. This is not the first time this particular rumor has cropped up. In his first tour as Bentley CEO, Durheimer brought a full-size convertible, called the Mulsanne Vision (shown above) to Pebble Beach in 2012. The idea was shelved by his successor, Wolfgang Schreiber, in 2013. But with Durheimer back in his old position in Crewe (and heading up efforts at Bugatti, too), it wasn't long before Bentley was back in the convertible Mulsanne game with the Grand Convertible, a Speed-based droptop. When the Grand Convertible debuted, we said the company is "watching customer reaction to the car." And the press release says the luxury droptop was "developed to signify Bentley's intentions for the future." Consider this most recent story a reinforcement of that report, then.
