Bentley builds its final 6.75-liter V8, ending a 61-year production run

Bentley has just finished its very last 6.75-liter V8. While engines come and go, this is significant because Bentley has been building this engine, known as the L-series, for 61 years. This final engine will go in the 30th and last Bentley Mulsanne, a 6.75 Edition by Mulliner, marking the end of the flagship sedan. The L-series engine was first introduced in 1959, and according to Bentley, it was developed in order to develop more power than its existing inline-six without adding weight or taking up more space. The engine in fact weighed 30 pounds less than the six-cylinder, and it made about 180 horsepower. That original engine "only" had 6.2-liters of displacement, and it wasn't until 1971 that it would reach 6.75 liters thanks to increased stroke. This final version of the engine is significantly different from its fuel injection to its twin-turbochargers, but is based on the same design. And with 530 horsepower and 811 pound-feet of torque, it's the most powerful iteration of the engine. At 61 years, the Bentley engine is arguably the V8 with the longest production run. While the first-generation Chevy small block V8 was introduced earlier for the 1955 model year and is still built in crate engine form, GM stopped using it in production cars in 2002. Far fewer Bentley engines were built, though, with a total over 36,000, as opposed to the millions of Chevy small blocks in the world. Of course, volume is sort of the antithesis of what makes a Bentley a Bentley. With the 6.75-liter engine out of production, all of Bentley's engines are derived from VW Group engines, from its W12 to the plug-in hybrid V6. Related Video:    

Bentley Azure could return for limited edition

Once upon a time, Bentley had two convertibles in its lineup – there was the Continental GTC, which you can still enjoy today, and the Azure, which you can't. The bigger offering, based on the Arnage sedan, went out of production several years back, much to the disappointment of those with ostentatious tastes and bottomless pockets. But if Wolfgang Durheimer has his way, the 20-plus-year-old nameplate could return in a limited run based on the Mulsanne. The last Azure demanded ridiculous wealth to purchase, but this new model would be on an entirely different level. According to Car and Driver, Durheimer said a reborn Azure "would be built in [a batch of] 20 units and sold to absolute connoisseurs at a very high price." He stopped short of actually confirming the vehicle or its cost, but that hasn't stopped Car and Driver from suggesting a price of $1 to $1.5 million per vehicle. The timing here is fascinating, largely because Bentley's arch-rival, Rolls-Royce, is preparing to phase out its Phantom Drophead Coupe – the Mulsanne Convertible's most natural rival – due to slow sales. Whatever this limited-edition vehicle is called, it'd be all on its own. This is not the first time this particular rumor has cropped up. In his first tour as Bentley CEO, Durheimer brought a full-size convertible, called the Mulsanne Vision (shown above) to Pebble Beach in 2012. The idea was shelved by his successor, Wolfgang Schreiber, in 2013. But with Durheimer back in his old position in Crewe (and heading up efforts at Bugatti, too), it wasn't long before Bentley was back in the convertible Mulsanne game with the Grand Convertible, a Speed-based droptop. When the Grand Convertible debuted, we said the company is "watching customer reaction to the car." And the press release says the luxury droptop was "developed to signify Bentley's intentions for the future." Consider this most recent story a reinforcement of that report, then.

Bentley Continental GT3 grows wings to conquer the Pikes Peak Hill Climb

Apparently, this is a Bentley. That may not be obvious at first glance on account of the … everything, but this winged beast does have a Bentley logo on it. You see, Bentley is headed on back to Pikes Peak for a third (and final) time. The companyÂ’s first two visits saw the production SUV record achieved with the Bentayga W12 and the outright production car record taken with the Continental GT. This time, Bentley is targeting the “Time Attack 1” record, and the Continental GT3 Pikes Peak is its steed of choice. Leading the car's superlative features is what Bentley claims to be “the biggest rear wing ever fitted to a Bentley.” We heartily approve. The aerodynamic package is fully in vogue with other cars built specifically for Pikes Peak. Maximum downforce is generated with the huge wing, a gigantic diffuser, two-plane splitter and aggressive dive planes. ItÂ’s more track rat than elegant race car with the numerous scoops and venting throughout. The exhaust cutouts just aft of the front wheels complete the hooligan package. This Continental may have Bentley lights on it, but the similarities between it and the road car donÂ’t go much further. Details about the engine are limited, but Bentley says itÂ’s a 4.0-liter turbocharged V8 racing engine, not a production V8 or W12. Modifications were made to make it more powerful for this Pikes Peak run, but Bentley also made adjustments for the fuel it will be running in the car. Instead of running this Continental on race fuel, itÂ’s going to be using biofuel-based gasoline. WeÂ’ve heard Porsche make waves about the potential of greener biofuels helping to drastically reduce emissions, and now Bentley is making some noise about the tech, too. In coordination with Porsche (all in the same VW Group house), Bentley is researching how it could use biofuels and “e-fuels” to potentially power both past and future Bentley cars. As of today, Bentley is saying that using these fuels could result in greenhouse gas emissions reductions of up to 85%. Put simply, thatÂ’s huge, if it can be made to work at a large scale. Bentley expressly states that this research into biofuels doesnÂ’t affect its plan to become an electric-only automaker by 2030. Instead, Bentley sees it as a way to allow the brandÂ’s past and current gasoline-powered vehicles to be driven far into the future — just over 80% of all Bentleys ever built are still on the road, according to BentleyÂ’s internal tracking.
