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.

Weekly Recap: Takeaways from the Frankfurt Motor Show

We obsessively covered the 2015 Frankfurt Motor Show, and naturally, we selected our favorites from this fall's biggest automotive event. Now that the dust has settled, we're looking ahead to what it all means. Here are three takeaways from the floor in Frankfurt. The Germans are serious about electric vehicles: It's a bit cliche to say BMW, Mercedes, and Audi have downplayed electrics in favor of other technologies, like diesels. For a time that may have been true, but those three companies, along with Porsche and Volkswagen, are emerging as leaders in EV development. That was on display in Frankfurt, when all of them revealed either all-electric or plug-in hybrid models. Gas prices are relatively low in the United States, but clearly the Germans are thinking long-term and globally. Everyone is serious about SUVs: You gotta have one, even if you're Bentley or Jaguar. It's 2015 and it's what consumers want. As Jaguar design director Ian Callum put it, "Not to be in the sector would be a little naive for the sake of purity." It's not just the flashy exotic luxury makers. Nissan showed the Gripz concept, which is rakish, radical, and meant to blend traits of SUVs and sports cars into a vehicle that really crosses over. Look for more, especially in the luxury sector, as Rolls-Royce, Lamborghini, and Aston Martin ramp up their own SUV efforts. There's no ceiling to the luxury market: Speaking of high-end cars, companies are continuing to invest in extravagant wares beyond just SUVs. Even during the recession, ultra-luxury makers remained relevant, and now they're back at full stride. In Frankfurt, that was illustrated by yet another S-Class model, the cabriolet, which will come in S550 and S63 AMG variants in the United States. Ferrari also showed off the 488 Spider, and Lamborghini opened up the Huracan LP 610-4 Spyder. Meanwhile, Bugatti's Vision Grand Turismo concept reminded enthusiasts that it's plotting life after the Veyron. European auto shows always draw the glitziest reveals from luxury makers, and this year didn't disappoint. OTHER NEWS & NOTES 2016 Honda Civic redesigned with snazzier style, turbo power The 10th-generation of the Honda Civic debuted this week at events in Los Angeles and Detroit ahead of its launch in the United States this fall as a 2016 model.

Bentley Bentayga plug-in hybrid spied using V6 power

Bentley confirmed plans for a plug-in hybrid version of the Bentayga in early 2015 and said the electric SUV would be ready for 2017. It seems that the luxury automaker will keep its word, because one of our spy photographers spotted this nearly undisguised model out testing. It looks identical to the normal Bentayga, with the exception of an additional little flap on the left side for a plug. Although Bentley confirmed the hybrid's development way back in 2015, it left out a few details about what the powertrain would be, only saying it would either be a V8 or a V6. Our spy photographer was able to shed some light on this by looking up the prototype's registration. Apparently it has a 3.0-liter engine under its proud hood, so it's a reasonable bet the Bentayga has a V6. Since Bentley promised the hybrid would be ready for 2017, and because this car is hiding almost nothing, we would expect to see the car make a full debut by the end of the year. It should have an electric range of just over 30 miles.
