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 Grand Convertible is grand, is a convertible

What you see above is the Bentley Grand Convertible, live from the Los Angeles Auto Show. It's basically a droptop version of the Mulsanne Speed, which would seem to be a foregone conclusion for production, but apparently isn't, according to Bentley Chairman and CEO, Wolfgang Dürheimer.
"We are eagerly awaiting the response of our customers to this car. We will ensure that this car - if it reaches the roads - will be a highly exclusive, extremely limited collector's piece."
With its production possibilities out of the way, and with the image gallery you see above proving that it is, indeed, a convertible, we can move on to what makes this Grand Convertible so grand. Equipped with the same 6.75-liter engine with 530 horsepower and 811 pound-feet of torque as its hardtop brethren, it certainly won't be lacking for power. The Grand Convertible has been "fashioned entirely by hand from the very finest materials," says Bentley, and the tonneau is made from the largest piece of wood veneer ever applied by the automaker.

2023 Bentley Flying Spur Speed keeps the W12 alive with 626 horsepower

Bentley has expanded the Flying Spur range with a performance-oriented variant appropriately called Speed. The sedan stands out from other members of the Flying Spur lineup with a powerful W12 engine between its fenders, a firmer chassis setup, and a specific design. The company has traditionally reserved the "Speed" designation for its driver-focused models, and the Flying Spur lives up to this badge with a 6.0-liter W12 engine that's twin-turbocharged to develop 626 horsepower and 664 pound-feet of torque. In comparison, the next model down is the Flying Spur S, which uses a 4.0-liter, twin-turbocharged V8 rated at 542 horsepower and 568 pound-feet of torque. Bentley pegs the Speed's zero-to-60-mph time at 3.7 seconds, and the big sedan doesn't stop accelerating until its speedometer displays 207 mph. An eight-speed automatic transmission transfers the 12-cylinder's output to the four wheels via a rear-biased all-wheel-drive system, and reaching the Speed's top speed requires leaving the gearbox in sixth. Seventh and eighth are overdrive gears used to keep the engine's revolutions relatively low at higher speeds. Four-wheel steering, Torque Vectoring by Brake technology, and the 48-volt Bentley Dynamic Ride system help drivers make the most of the extra power. Massive brakes are found on the list of standard features as well. Visually, the Speed gains black exterior trim, "Speed" emblems on the lower part of the fenders, and model-specific 22-inch wheels. Buyers have several options to choose from, including the Styling Specification and Blackline Specification packages. Inside, the Speed features Dinamica Pure upholstery, a redesigned instrument cluster, sport pedals, 24-way power-adjustable front comfort seats, and 14-way power-adjustable rear seats. Both rows of seats are heated, ventilated, and equipped with a massage function; Bentley argues that performance and comfort aren't mutually exclusive. Piano Black trim comes standard but other types of wood (like Crown Cut Walnut) are no-cost options. Pricing information for the 2023 Bentley Flying Spur Speed hasn't been released yet.
