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 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.

Bentley wants to get into the coachbuilding business

There was a time when a customer would buy a chassis from an automaker like Bentley and then take it to a coachbuilder to have whatever bodywork they wanted put on it. The practice was particularly prevalent in Bentley's earlier days, but the industry has progressed in such a way - with tighter regulations and unibody construction - that such a practice is no longer feasible. But Bentley wants to get back into that business.
Speaking to UK trade publications recently, Bentley sales chief Kevin Rose indicated that the company is looking into setting up a special division within itself to meet the demands of extremely wealthy customers who want to commission their own coachbuilt custom creations. It's an emerging trend that's seen Ferrari Special Projects build one-offs like the F12 TRS and SP12 EC and McLaren Special Operations the outlandish X-1, and Bentley wants to get in on the action.
It wouldn't be the first even to rebody a contemporary Bentley in recent years. Carrozzeria Touring Superleggera offers the Flying Star (pictured above) that turns the Continental GT into a shooting brake, and Dany Bahar's new coachbuilding outfit Ares plans to do the same. By bringing it in-house, however, Bentley would be able to pick the chassis up off the assembly line at the right time and provide the necessary support and factory backing.
