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 Bentayga to add gasoline V8 before plug-in hybrid powertrains bows

The Bentley Bentayga offers exactly one powertrain in the US: a 6.0 liter W12 with 600 horsepower and 664 pound-feet of torque. Overseas buyers get the additional option of a 4.0 liter diesel V8 with 429 hp and 664 lb-ft - the same oil burner from the Audi SQ7, denied us after Volkswagen Group pulled diesels from the US market. Auto Motor und Sport reports that Bentley will add two more powertrains to the mix over the next year, but it's unclear whether any of them will come here: a 4.0-liter gasoline V8, and a plug-in hybrid. The German publication expects the Porsche-developed 4.0-liter, twin-turbo V8 to get the nod for Bentley use. That engine serves in the Porsche Cayenne Turbo (550 hp/567 lb-ft) and Lamborghini Urus (650 hp/627 lb-ft), which both share their MLB platform with the Bentayga. Making sure not to step on the toes of the W12, the 4.0-liter petrol V8 will get something like the Cayenne Turbo's 550 hp. We've seen spy shots of the Bentayga PHEV testing at the Nurburgring, but we weren't sure what the SUV used for motivation. Porsche again donates equipment for the plug-in hybrid Bentayga, the forthcoming powertrain swiped from the Panamera 4 E-Hybrid. In the Porsche, total output comes to 462 hp and 516 lb-ft. Spy shooters captured a photo of an "EV Mode" button inside the Bentayga, so we know it will do silent running; the 14.1 kWh battery in the Panamera E-Hybrid provides 31 miles of electric-only range. Both powertrains will provide a lower price point for the Bentayga compared to the W12, a stat line that should increase the big Bentley's appeal even though sales already qualify as gangbusters, considering the vehicle. According to AMS, the 4.0-liter gas V8 Bentayga should show up sometime around summer 2018, the PHEV to follow. 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.
