Bentley Continental GT3 Pikes Peak racer puts out 750 horsepower on biofuel

Bentley revealed its Continental GT3 Pikes Peak car to us earlier this year, but was short on engine details. That left us especially curious, as Bentley foreshadowed lots of modifications and a promise that it’d run on a renewable biofuel. Of course, more power than standard was expected. Today, all the details of this wild Bentley are available. Its 4.0-liter twin-turbo V8 engine will make “more than” 750 horsepower and 738 pound-feet of torque. ThatÂ’s a 100 horsepower increase over the most potent street version of the Continental, the Continental GT Speed. HowÂ’d Bentley do it? For starters, Bentley began with the GT3 race version of its 4.0-liter V8, not the street version. But Bentley went to town on this race engine for Pikes Peak anyway. It has new pistons and connecting rods, plus the boost is turned up to 2.2 bar with larger turbos. The carbon fiber intake manifold is reinforced and made thicker than the standard one. Plus, one-off exhaust manifolds made from Inconel alloy by Akrapovic are fitted. The exhaust ultimately exits via very short pipes just behind the front wheels. Not very Bentley-like. Cooling is reinforced by a secondary cooling system positioned in the rear of the car. The rear windows are traded for air scoops that channel air through a second radiator, exhausting heat through ducts in the trunk lid. It all runs off a dedicated secondary water pump. Another change youÂ’ll find at the rear is a new driveshaft with a larger diameter for better durability. The biofuel Bentley uses is called 98RON Renewable Racing Fuel, and Bentley says it is "a dedicated blend of advanced biofuels specifically designed for motorsport, and is a technological stepping stone to sustainably-created eFuel with a greenhouse gas reduction of up to 85%." Bentley didn't say what the emissions reduction was for this specific biofuel in the Pikes Peak car. When it comes to handling, Bentley says it has significantly modified the GT3 setup. ItÂ’s running far more camber in front and rear. Softer springs and anti-roll bars were fitted to allow more body movement and maximize weight transfer for braking (keep in mind all your braking will be done while going straight uphill). Plus, the brakes themselves are newly water-cooled to handle the extreme loads that this hill climb will put on them. You can watch out for Bentley's attempt at a record on June 27, a day that will mark the 99th running of the Pikes Peak International Hill Climb.

Bentley's SUV will be first of many plug-in hybrids

Bentley is not exactly a company known for its environmental credentials. Sure, it recently cut its water usage down by over a third, and given the relatively small number of vehicles it produces, the British firm's overall impact on the environment may be negligible compared to mass-market rivals. And of course, its affluent customers are hardly likely to feel the pinch of rising fuel costs, so Bentley's idea of engine downsizing has been going from twelve cylinders to eight.
That will all change with the launch of its first SUV, previewed by the controversial EXP 9 F concept and expected to be called Falcon. To hear Auto Express tell it, the luxo-ute is being designed from the get-go to incorporate a plug-in hybrid powertrain, slated to go on sale a year after the conventional version arrives late in 2015 or early 2016. But that's just the tip of the iceberg which Bentley is trying to help keep from melting.
Following the Falcon, other Bentleys are slated to get PHEV systems as well. It'll just take a while. That's because current models like the Continental and Mulsanne were never designed to incorporate PHEV powertrain systems in the first place. So while they may get them in the long run, their integration will likely have to wait until their replacements arrive.

Bentley Bentayga by Mulliner is a one-off special edition with ties to horse racing

Not long ago, we featured the Bentley Bentayga Field Sports by Mulliner, Bentley's even more lavish companion that often adds a special touch to production Bentleys; earlier on, there was even a version aimed at falconers. Here's another one-off Bentayga special edition that looks just as ostentatious, simply called the Bentayga by Mulliner. Bentley says this Mulliner version has been inspired by horse racing, and it's been created to commemorate Bentley's partnership with racetrack operator The Jockey Club at the Cheltenham Festival. It has to be said, the Bentayga looks far better by itself than towing a horse box on the highway. The paintwork is a variation on British Racing Green, on this occasion called Spruce, and the cabin has been finished with a combination of saddle-colored leather on the seats and special tweed on the doors. The veneer is burr walnut, treated to resemble woodwork at The Jockey Club's private rooms, and branded Mulliner. As well as Cheltenham Racecourse, The Jockey Club operates 14 other horse racing venues in the UK, and it was founded all the way back in 1750. The 21" wheels on the Bentayga by Mulliner are the same, partially black ones that were fitted on the Field Sports.
