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.

VW Group plan puts Porsche in charge of a 'super-premium' division

An Automobile report looks into what's happening on the organizational and technical sides of the Volkswagen Group, and what those changes could mean for the premium brands. The wide-angle view is that Porsche appears to have been anointed to "coordinate the future activities" at Audi, Bentley, Bugatti and Lamborghini. Audi would cede Lamborghini guardianship to Stuttgart, and Ducati — via a new concern called Ducati Enterprises — would become the shepherd for VW's other Italian investments. Executives target Jan. 1, 2019, to complete the reshuffle. VW wants to save a boodle by tying up four of its five top-tier brands, and putting the one with the highest ROI in charge. Porsche, within its own house, wants to reduce expenditures by $2.3 billion per year over for four years, the savings already earmarked for improving internal processes like R&D and production. Having Porsche share those gains as well as lead development of platforms, components and future-tech strategies for the sister sports car brands could benefit everyone. In the near-term, the brands have their own plans: Bugatti CEO Stephan Winkelmann is said to want a Chiron Superleggera, a roofless and "completely reskinned" Chiron Aperta, and a track-only Chiron SS. The Superleggera could take the Chiron Sport's and Divo's Jenny Craig routines even further. The Aperta seems a natural successor to the Veyron Grand Sport, a natural evolution of the recently introduced Sky View roof, and a reskin might include numerous Divo cues. It's also said Bugatti's considering "an all-electric high-end model" in conjunction with Porsche, Rimac, and Dallara, but name one supercar or hypercar manufacturer that isn't considering a lightning-fast EV. Lamborghini, deep into work on follow-ups for the Huracan and Aventador, might get a bit of a bump with the new plan. The carbon "monofuselage" for the next V12 flagship is said to be too far developed and too complex to scrap. It puts two electric motors on the front axle, batteries in the middle, and a naturally aspirated V12 with around 770 horsepower plus another e-motor with 402 horsepower in back. The Huracan is said to get a version of the same carbon architecture at the moment, but the corporate reorganization might press pause on it. Automobile says options include continuing the Huracan/ Audi R8 twinning, but that depends on Audi saying "Ja" to a third-gen R8 with Lamborghini bones.

2022 Bentley Continental GT Speed debuts with more power, big handling improvements

Fast news is coming out of the UK today in the form of a new Bentley Continental GT Speed. Similar to the previous generations of the Continental GT, this latest version is getting the Speed treatment. Bentley may be talking endlessly about its green future, but until that materializes, the British marque is continuing to pump out W12 master classes of luxury and speed. The idea is the same as all “Speed” versions of recent Bentleys. Add power, increase handling abilities, and make it look faster. Power from the 6.0-liter twin-turbo W12 increases to 650 horsepower (24 extra ponies), while torque remains constant at 664 pound-feet. The extra power comes from increasing the manifold pressure in the upper rev range, meaning the extra power is all the top. This results in a 0.1-second reduction in the 0-60 mph time, which is now down to 3.5 seconds. Top speed is a lofty 208 mph, which is a 1 mph increase from the non-Speed. See, itÂ’s speedier! While the power gains are admittedly small, the other performance improvements Bentley made look like theyÂ’ll be much more noticeable from behind the wheel. For one, the eight-speed dual-clutch transmission reportedly shifts twice as fast in Sport mode as it does in the regular W12 model. The engine and transmission calibration is also revised to make its upshifts higher in the rev band and downshift earlier. Bentley says the exhaust is much louder with greater “character” than the standard car, too. The chassis and drive system get significant updates for better handling. The car's big new party trick is four-wheel steering, which is becoming increasingly common for large luxury cars. As you might expect, the rear wheels turn opposite the fronts at low speeds for better agility, and the rears turn the same direction as the fronts at high speeds for better stability. This means the Continental GT Speed should feel more nimble and quick on its feet than lesser versions.  Additionally, Bentley says itÂ’s using a new all-wheel-drive torque split and traction control calibration “to provide a noticeable character shift” for the Speed. Basically, theyÂ’re loosening the reins a bit, which will ultimately result in the Speed feeling more tail-happy and eager to rotate in corners. Brake-based torque vectoring is implemented in the Speed for when you want to power through corners more efficiently, too.
