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:    

Question of the Day: What's the greatest British car ever?

The British automotive industry has produced everything from high-production econo-commuters to staggeringly luxurious oligarch-wagons, along the way winning plenty of races and building plenty of beautiful machines. The original Mini led directly to the past half-century of transverse-engine, front-wheel-drive cars built everywhere, the MGB put the sporty little convertible into everyone's reach, and the Morris Oxford became the most beloved motor vehicle in India. So many to choose from, but we want you to pick one. What will it be? Related Video:

Bentley starts testing the sold-out, 200-mph Bacalar roadster

Bentley took the limited-edition Bacalar from a sketch to a 200-plus-mph roadster in nine months, a shockingly short amount of time. Its engineers are now putting the first car through its paces at the same break-neck speed. Although the Bacalar is based on the Continental GT, the British firm explained nearly everything the driver will see and feel is specific to the car. Bentley developed over 750 new parts for it, including 40 built with carbon fiber, and the roadster shares no body panels with other members of the company's range. All of these components have to meet the same stringent quality standards as those created for regular-production models. Bentley gave its team 20 weeks to fine-tune the first prototype (pictured), which it calls car zero. Testing started earlier in 2020, so the car has already been put through a wind tunnel and pushed to the limit at triple-digit speeds — it's as stable and quiet as customers expect. Next, test drivers will pile on the miles to see how it holds up over time. They'll then test it at up to 176 degrees, and the final step will be validating the electrical system. Power for the Bacalar comes from a twin-turbocharged 6.0-liter W12 engine, which produces 650 horsepower and 667 pound-feet of torque. It spins the four wheels through an eight-speed automatic transmission. Bentley hasn't revealed what it will do with car zero at the end of the testing phase. Production is scheduled to start in 2021, and the 12 examples planned have already been spoken for. Each one will be unique; buyers will be invited to work directly with the company's design department to configure the interior and the exterior. Related Video:
