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 Mulliner Bacalar is probably a roadster

The upcoming coachbuilt Bentley Mulliner Bacalar has been teased before its Geneva Motor Show reveal once again. Instead of one of the wheels or a glimpse of its rear quarter panels, we get a rather clear view of the interior. Bentley highlights the fact that there are only two seats, making this only the second two-seat car the company has offered since 1930. But looking closely, it also suggests that the Mulliner Bacalar is a convertible. The first indication is the angle of the photo, which is clearly from high up, and generally unobstructed. Perhaps it could be a design buck, but there's more to it than that. At the bottom of the photo, there's a black, horizontal object obscuring the base of the seats. It's too close to the seat backs to be the dashboard, so we think it's actually the windshield header. Then there's the placement of the seatbelts. They're mounted really low in the interior, seemingly below the window line. That's something automakers normally do if there are no pillars to mount to higher up, and if you didn't want to mount them to the seats. There also appears to be trim wrapping around behind the rear cargo area at the same height, further suggesting there's no solid roof and pillars in place. With all this under consideration, plus a previous report of a convertible in the works, we're thinking the Bacalar is a droptop of some sort. Taking a turn back to what's obvious in the photo, the interior is clearly a two-seat design, and you can see that it features matching luggage to fit the cavity behind the seats. The seats are upholstered in a nifty and sporty-looking diamond pattern with contrasting gray and yellow fabrics. Bentley doesn't specifically say what materials are used, but it says everything was sustainably sourced. The Mulliner Bacalar will be fully revealed on March 3 at the Geneva Motor Show. It will apparently take styling inspiration from the electric EXP 100 GT concept, and Bentley is stressing the sustainability aspect of the car. The same report that said a convertible was coming, though, also said it would probably get a W12 engine, and at least the convertible part of the report seems to be true. Also expect a price tag well into the seven figure range. Related Video:

Bentley Mulsanne convertible expected to be greenlit this year

That was quick - it was only was only three weeks ago that the Bentley Mulsanne Vision concept, a droptop take on the brand's flagship sedan, was sketched out for the Pebble Beach crowd. Now Autocar reports that a production version is expected to be approved later this year, with a launch something like two years away. And even though it hasn't been officially given the go-ahead, it has a price: "at least £275,000" ($436,232 U.S.). That price would make for a £50,000 premium ($79,313 U.S.) - at least - over the current UK price of the Mulsanne sedan.
Just as the Continental GTC differs from its coupe sibling, Autocar says the Mulsanne cabrio would be unique from the A-pillars back as compared to the sedan. Shortened by roughly six inches in both length and wheelbase, frameless doors and a lowered windshield will contribute additional rakishness, and note the rear fender treatment meant to evoke the fifties-era Bentley R Type in the upper right corner of the sketch above. At launch it is predicted that power will come from the twin-turbo 6.75-liter V8, but Autocar predicts that V12 power being developed for the production version of the EXP 9 F SUV will eventually find its way up front.
