Xcar asks why the W in the Bentley Continental GT

There aren't a lot of automakers producing V12 engines these days: There's BMW and Mercedes, of course, and the Rolls-Royces and Paganis they power. There's Ferrari, Lamborghini and Aston Martin. But the largest producer of twelve-cylinder engines doesn't make them in a V. That'd be Bentley, and it produces more dozen-piston engines than anyone else, but arranges them in a W configuration. It's a compelling story of innovation, one as interesting as the history of the marque itself. And Xcar tells the tale in its latest video installment, tracing it back to the development of the compact VR6 engine and the autocratic mastermind at the helm of the Volkswagen Group who made the W12 a reality. By this point it would be all too easy to consign the W12 to the dustbin of history as the smaller, more efficient and nearly as powerful V8 has slotted in below to push the W12 to the margins of relevance. But it's still the more refined option, and the more innovative one. Little wonder it's the only type of twelve-cylinder engine (the Aventador's notwithstanding) that the Volkswagen Group still makes.

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.

Porsche recalling 24,500 Panameras for a potential HVAC coolant pump issue

A possible coolant pump problem for the HVAC system is causing Porsche to recall 24,467 units of the Panamera from the 2017 to 2020 model years. Bentley's recalling 650 examples of the sibling 2020 Continental GT for the same issue. Porsche was notified of a malfunction in the external heat pump for the Panamera's climate control in December 2022. An automaker investigation found that it's possible for excess humidity or even liquid to get past the pump seals and short out the pump's circuit board and connector. In rare instances, the malfunction could cause a fire. This can happen even when the engine is turned off because the cars in question are equipped with a residual heat function that keeps warming the cabin after shutdown. Panameras built after July 26, 2021 were fitted with a different pump. The Stuttgart carmaker's field analysis showed "a very small number of instances of thermal damage possibly attributable to this issue." Bentley changed the part in July 2019 to a model with a pressure compensation seal. Porsche said it will begin notifying owners on March 27. It also said it will reimburse any Panamera owners who have paid to have the part fixed previous to this recall. The fix is a trip to the dealer for a new pump with better sealing, sourced from a new supplier. Bentley will begin notifying owners on the same day. In Bentley's case, though, the automaker says "A hardware change will be required but the final solution is currently under investigation and cannot be confirmed at this time." Since the automaker moved to a new pump that isn't part of the recall population, we aren't sure why a resolution remains under investigation. Porsche owners can contact Porsche customer service at 800-767-7243 and refer to internal recall number APA1. Bentley owners can call 800-777-6923 and refer to RE23/02 (RC67). Anyone in that group can go straight to the National Highway Transportation Safety Administration at 888-327-4236 (TTY 1-800-424-9153) or nhtsa.gov, citing campaign number 23V033 for the Panamera or 23V034 for the Bentley.
