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:

Bentley's first electric car will arrive in 2025 at the earliest

Now that it's back in the black, Bentley is busily planning its move into the electric car segment. The company's chief executive shed light on how his team will link the past and the future. When it comes to new products, company boss Adrian Hallmark told Automotive News Europe that "it's all about electrification." The first Bentley with a plug is the Bentayga Hybrid unveiled at the 2018 Geneva Motor Show. Looking ahead, an electric car will join the range, but executives haven't decided what form it will take, or what it will be powered by. Several options remain on the table. What's certain is that Bentley won't stuff an electric powertrain into one of the cars in its current portfolio. "We could take one of the existing nameplates, and that could be the first electric car, but we wouldn't take an existing car and try to fit batteries into it, because there's a compromise from a range and efficiency point of view," Hallmark explained. The challenge isn't simply to make an electric Bentley; the British firm wants to ensure its first battery-powered model credibly lives up to the badge on its nose. That means it needs to blend effortless power with an acceptable amount of driving range. Bentley is part of Volkswagen, so using one of the platforms in the group's growing arsenal of architectures isn't out of the question. And, Hallmark affirmed engineers will take advantage of the innovative packaging possibilities made possible by electric powertrains. He explained the firm isn't about to release a Mini, but an electric Bentley could have a smaller footprint than, say, a Mulsanne while offering a comparable amount of interior space. He cited the Jaguar I-Pace as an example, which he said is nearly 14 inches shorter than Land Rover's Range Rover, yet is about as spacious inside because electric motors require less space than a comparable gasoline- or diesel-burning engine. The trade-off is that an electric Bentley would need a sizable battery pack, and designers would likely have to put the car on stilts to leave enough room in the cabin for people and gear if they were to pen an electric car in 2020. Solid-state battery technology will solve that problem when it's ready for production, according to Hallmark, though he didn't reveal whether he's open to waiting for the new chemistry or if Bentley's first electric car will ship with a lithium-ion battery pack.

Bentley installing 10,000 solar panels in HQ parking lot

Bentley has started construction on what it says will be the U.K.'s largest solar-powered car port at its factory headquarters in Crewe, England. When completed, the array will have a capacity of 2.7 megawatts, enough to cover 24 percent of the company's energy requirements on the site. Crews will install 10,000 solar panels in the employee car port in a project that's expected to take six months. They'll add to the 20,815-panel, 5mW rooftop solar power system that Bentley finished installing at the factory in 2013. The combined output will be enough to power the equivalent of 1,750 homes. The car port will cover 1,378 parking spaces and be installed and operated by British firm FlexiSolar, which is also designing and manufacturing the system. The new green energy system adds to plaudits in recent years for reducing its water usage at the Crewe HQ. Bentley has also been awarded the Carbon Trust Standards for carbon, water and waste. While Bentleys aren't exactly known for their fuel efficiency — the Mulsanne sedan gets a woeful 11 mpg in the city and 18 mpg on the highway — its vehicles no longer appear on the American Council for an Energy-Efficient Economy's "meanest" list of gas-guzzlers, as they once did. It also just showed its forthcoming and long-promised Bentayga plug-in hybrid in Geneva, promising 31 miles of all-electric range and a turbocharged 3.0-liter V6 paired with an electric motor. The brand is also promising a full-electric model in the near future. "We continue to focus on new initiatives that reinforce our commitment to the environment, whether this is introducing alternative powertrain technologies in future models, or our award-winning work to reduce the environmental impact of our factory," Peter Bosch, Bentley's member of the Board for Manufacturing, said in a statement.
