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 reveals Continental GT V8 S with a bit more of everything

A Bentley seldom lacks for power, but the entry-level, V8-powered Continental GT and GTC will be getting just a bit more when the doors open at the 2013 Frankfurt Motor Show. The 4.0-liter twin-turbocharged V8 in the new Continental GT V8 S and GTC V8 S has been upgraded by 21 horsepower and 15 pound-feet of torque to bring output up to 521 hp and 502 lb-ft. That's no earth-shattering boost, but when you're dealing with a car that weighs over 5,000 pounds, ever little bit helps.
In a rare best-of-both worlds scenario, Bentley has managed to squeeze the extra thrust out of the Audi-derived engine without sacrificing fuel economy, enabling the new V8 S models to cover the same 500 miles on a full tank as the existing Continental GT V8. But the crew from Crewe didn't stop there: they also lowered the suspension by ten millimeters (0.39 inches), stiffened the spring rates by 45% up front and 33% in the rear, tweaked the dampers, fitted a stiffer rear sway bar and recalibrated the stability control, all in the aim of providing a more assertive, engaging driving experience.
The revised models can be identified by their tweaked front and rear fascias, black grille and unique 20-inch wheels. As of right now, it's not clear how much the V8 S will cost over the standard eight-pot Conti, but then Bentleys don't come cheap in the first place. Deliveries are set to begin early in 2014, by which time we hope to have more specifics on price and availability.

Bentley Continental GT3-R is a limited-edition racer for the street

Limited to just 300 examples worldwide, Bentley's new GT3-R is set to bring a bit of the brand's motorsports pedigree to the street. After all, the Flying B recently took the win at the Blancpain Endurance Series at Silverstone with its new Continental GT3, less than one year after the big racer's debut.
Like the road-going Conti GT, the GT3-R uses a twin-turbocharged 4.0-liter V8, tuned in this application to 572 horsepower and 516 pound-feet of torque - increases of 51 hp and 14 lb-ft from the already potent GT V8 S. That's enough to get the 4,839-pound Bentley to 60 miles per hour in just 3.6 seconds, on its way to a top end of 170 mph.
To make the GT3-R more hardcore than standard Continentals, the air suspension has been retuned, the brakes have been upgraded with carbon silicon discs, and there's a titanium exhaust that's good for 15 pounds of weight-savings - in all, the GT3-R is some 200 pounds lighter than a comparable GT V8 S.
