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:

Porsche to develop new line of engines for next Panamera

When the second generation of the four-door Porsche Panamera launches, it will likely be riding a new platform, complete with an all-new family of V6 and V8 engines, according to a report coming out of the UK.
Autocar reports that the so-called MSB platform will likely underpin the Panamera, and it could be shared with Bentley, provided the Volkswagen-owned, British-built brand commits to the architecture. As for the engines, it's reported that they'll have a sportier character than the V6s and V8s being built for Volkswagen and Audi's vehicles.
"Porsche will have its own new V8 that will be common to the new MSB platform," Porsche's chief engineer, Wolfgang Hatz, said. "It's a family for the next 10 years of cars." Whether the V8 and V6 will be used outside of the Panamera line, though, remains unclear. There's also no mention of what place turbocharging would have with the new engines.

Bentley Continental Flying Spur spied lapping the 'Ring

It's been months since we've heard anything about the next-gen Bentley Continental Flying Spur. We know the four-door variant of the Bentley Continental GT is coming sometime soon, but all we've seen so far is one batch of spy shots of a car that doesn't stray too far from the current model. This new batch of photos shows another familiar car lapping the Nurburgring. Although this car is still heavily camouflaged (with some stickers that make it look like the current car), we can make some good assumptions based on the Continental GT. The car will have a larger grille, a new headlight design and oval taillights that mirror the exhaust tips. Under the hood, we expect the turbocharged W12 to carry over. Look for V8 and plug-in hybrid variants to arrive sometime down the line. We don't know when the car will go on sale, but don't expect to wait too much longer. It's been eight months since the Continental GT was revealed, and this is really nothing more than a platform variant. Look for a full reveal sometime this summer.
