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:

2022 Bentley Bentayga gets the world's largest production carbon wheels

Carbon fiber wheels are becoming a hot commodity when it comes to sports cars, and for obvious reasons: They're light and strong. Now the technology is coming to SUVs, as the Bentley Bentayga will soon get the option of the woven and molded wheels. The wheels available will measure 22 inches in diameter, which Bentley says makes them the largest carbon fiber wheels in production. You can also rest assured that they'll be safe for a multi-ton SUV as they pass Germany's rigorous TUV testing and regulations. And they deliver on the lightweight promise, as each wheel weighs about 13 pounds less than an aluminum counterpart. Not only is that good for performance, but we'd bet they deliver a nicer ride, too. Bentley also highlights some other benefits of the carbon fiber wheels. Among them is greater rigidity. Bentley says that aluminum wheels can flex under load up to the equivalent of one degree of camber per G of force. And supposedly, the reduced flex will help reduce tire wear. We sincerely doubt any Bentayga driver will notice. Heck, we doubt many car enthusiasts would actually notice. But hey, luxury isn't entirely about what you'll really notice. Really, we suspect most people who pick up these wheels will do so because they like the look of the exposed carbon. And it should, as Bentley also mentions, match the available carbon exterior packages nicely. If you're looking to pick up a Bentayga with these wheels, they'll be available later this year. Pricing hasn't been announced. Related video: Byron plays rich in the 2021 Bentley Flying Spur V8 | Autoblog
