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:

2015 Bentley Continental GT3-R First Drive [w/video]

Racecars break. F1, NASCAR, IndyCar, GT3 – you name it – every go-fast machine built for the track is living on borrowed time. So it wasn't a complete surprise when, after traveling halfway around the world to drive Bentley's Continental GT3 racecar, the darn thing unceremoniously blew its rear differential on someone else's hot lap. While mentally recalibrating to the idea that my only takeaway from the three day commitment might be frequent flier miles, I realized an alternate vehicle on hand could make the trip worthwhile: the roadgoing, not-so-evil twin to the all-out race machine, the 2015 Bentley Continental GT3-R. You can hardly blame Bentley for the failure to proceed. The Flying B has been performing swimmingly well in the Blancpain Endurance Series, scoring three wins in its debut season and racking up a respectable 2015 so far. The dropped, spoilered, and severely trimmed-down GT3 racer reflects a ruthless abandon of all things luxurious and civilized. Over 50 ECUs were ditched from the road car; the doors alone, which typically weigh a lofty 125 pounds apiece, have been trimmed down to a wispy 15. Yes, the race version is a fearsome, sexy beast – and yes, this was quickly proving irrelevant because that drive was simply not meant to be.The Next Best Thing It's hard to call a $339,725 exotic a consolation prize. Climbing into the roadgoing GT3-R reveals a dramatic departure from the standard issue Conti: Not only is the color scheme unexpected (acid green on black and grey), so is the choice of materials (carbon fiber, Alcantara, not an inch of wood veneer in sight). Some pesky legacy remnants remain (antiquated navigation system, some weirdly pedestrian VW-sourced buttons and switches), but there's also a smattering of sweet details (those famous organ stop air vents, the green center indicator on the steering wheel, the pleasantly gripped Alcantara shifter). In all, 300 examples are being built, 99 of which are destined for the US. Unlike the somewhat sonorous GT V8 S upon which it's based, the GT3-R's titanium exhaust enables an even more exuberant, unapologetic, voluminous roar. Those exhaust gases are summoned from the 592-horsepower, 553-pound-foot, twin-turbocharged 4.0-liter V8, which gains 71 hp and 51 lb-ft over the V8 S model it's based on.
