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.

Rhys Millen will drive a Bentley Bentayga at Pikes Peak

Despite Bentley positioning its Bentayga SUV as a luxury vehicle, Bentley doesn't want us to forget that it's also a storied motorsport brand. Even the Bentayga can be used for record hunting, as Bentley is eager to show. It has hired two-time Pikes Peak hill climb winner Rhys Millen to take a Bentayga to the mountaintop. With the production SUV record in its sights, Bentley's Motorsport wing in Crewe has prepared a Bentayga for the attempt (which will be used as a benchmark for the Lamborghini Urus). The vehicle has been kept as stock as possible, as per the rules, and for safety reasons it features a full roll cage, a fire suppression system, racing seats and a harness. Still, Bentley has also enlisted exhaust crafters Akrapovic to give it a custom setup; Akrapovic has also done the exhaust for the Continental GT3-R. But the air suspension with its electric anti-roll control is kept stock, and the Pirelli rubber is also off-the-shelf stuff. The W12 engine's 600hp/664 lb-ft power figures also match the unmodified versions. We reported on Bentley's inclusion at the June 24 event earlier, but at that point the driver had not yet been announced. Millen, 45, from New Zealand, is reportedly the second-most-prolific Pikes Peak competitor in the world. The current production SUV record stands at 12:35.61, set by Paul Dallenbach with a Range Rover Sport in 2013. The Pikes Peak Bentayga's exterior has been finished with an unmistakable Radium Satin hue, but other than that and the carbon fiber body kit, it appears more like an everyday, run-of-the-mill Bentayga, not a wild Pikes Peak racer with a bookcase for a rear wing.

Bentley Bentayga crossover prototype keeps on strippin'

The Geneva Motor Show is over, and the stunning EXP 10 Speed 6 concept has had its moment in the limelight. But now it's back down to business for Bentley. That means working on getting its new Bentayga crossover to market, and from these latest spy shots, it seems that's exactly what the British automaker is up to. Pictured here wearing less clothing than ever before, the Bentayga looks pretty darn near ready for its debut. The pre-production prototype even has its full leather seats in place, with plastic covers to protect them as the development drivers (like the one trying his darnedest to block the shots) do their thing. Of course there are still some parts hidden from view, with thin foil covering the headlights, taillamps and rear quarter windows. There's also something weird going on with those gills on the rear door. And the wheels are likely to be replaced as the rest of the trim is installed. But by and large, what you see here is what the production version is expected to look like, sans the polish. Related Video:
