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 Bentley Bacalar went from a sketch to a 650-hp roadster in nine months

Bentley's Mulliner division cemented its status as a modern-day coachbuilder when it unveiled the Bacalar, a two-seater roadster loosely based on the Continental GT. Nearly every part that drivers will see and feel is specific to the model, including the body panels and most of the interior, yet the company created it in just nine months. Mulliner has worked on many one- and few-off models in the past, it notably turned the stately Mulsanne into a six-seater limousine in 2016, but the Bacalar (pictured) takes customization to an entirely new level. Repeated requests from its most loyal clients convinced Bentley to expand the scope of its coachbuilding division. "We felt a strong demand from our high-end customers. They asked again and again, 'can you do something very special?' They weren't talking about one of a hundred, but one of 10 or even one of one," explained Stefan Sielaff, the company's lead designer, in an interview with Autoblog. He added the Bacalar project started shortly after Bentley introduced the EXP 100 GT in 2019 to celebrate its 100th birthday. This explains some of the visual parallels between the two cars. While the concept was electric, the sold-out production model receives a mighty, 650-horsepower W12 engine because Bentley couldn't create a suitable battery-powered drivetrain in the short amount of time it had to make the roadster a reality. Sielaff stressed the effort his team put into making the Bacalar in nine months shouldn't be underestimated. "We had to make sure the car was road-legal, homologated, and certified. The car you would have seen at the Geneva auto show is literally what the customer will get. It's not a crazy show car. The only difference will be the colors and the materials, because we will work with each customer to make an individual statement," he said. In the United States, the Bacalar will be imported under the Show and Display law, like the McLaren Speedtail. The expedited design process meant the 12 future Bacalar owners signed the dotted line after seeing only digital renderings of the car. They weren't shown the final product until much later. Their enthusiasm is encouraging; it tells Sielaff there's a tremendous appetite for one- and few-off Bentley models among wealthy clients.

2022 Bentley Continental GT Speed debuts with more power, big handling improvements

Fast news is coming out of the UK today in the form of a new Bentley Continental GT Speed. Similar to the previous generations of the Continental GT, this latest version is getting the Speed treatment. Bentley may be talking endlessly about its green future, but until that materializes, the British marque is continuing to pump out W12 master classes of luxury and speed. The idea is the same as all “Speed” versions of recent Bentleys. Add power, increase handling abilities, and make it look faster. Power from the 6.0-liter twin-turbo W12 increases to 650 horsepower (24 extra ponies), while torque remains constant at 664 pound-feet. The extra power comes from increasing the manifold pressure in the upper rev range, meaning the extra power is all the top. This results in a 0.1-second reduction in the 0-60 mph time, which is now down to 3.5 seconds. Top speed is a lofty 208 mph, which is a 1 mph increase from the non-Speed. See, itÂ’s speedier! While the power gains are admittedly small, the other performance improvements Bentley made look like theyÂ’ll be much more noticeable from behind the wheel. For one, the eight-speed dual-clutch transmission reportedly shifts twice as fast in Sport mode as it does in the regular W12 model. The engine and transmission calibration is also revised to make its upshifts higher in the rev band and downshift earlier. Bentley says the exhaust is much louder with greater “character” than the standard car, too. The chassis and drive system get significant updates for better handling. The car's big new party trick is four-wheel steering, which is becoming increasingly common for large luxury cars. As you might expect, the rear wheels turn opposite the fronts at low speeds for better agility, and the rears turn the same direction as the fronts at high speeds for better stability. This means the Continental GT Speed should feel more nimble and quick on its feet than lesser versions.  Additionally, Bentley says itÂ’s using a new all-wheel-drive torque split and traction control calibration “to provide a noticeable character shift” for the Speed. Basically, theyÂ’re loosening the reins a bit, which will ultimately result in the Speed feeling more tail-happy and eager to rotate in corners. Brake-based torque vectoring is implemented in the Speed for when you want to power through corners more efficiently, too.
