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:    

The renowned Bentley Blower returns to race again

Defining the Bentley Blower as a monumentally classic racing machine is a massive understatement. And now a modern example of the Blower — called Car Zero — has been built by hand, a copy of the 1929 4 1/2 -liter supercharged car, and it will race yet again. The indomitable Blower, so named for the Roots-type supercharger (built by Amherst Villiers) bolted in at the front of the magnesium crankcase, has been resurrected and will compete at the Circuit de la Sarthe  — translated: Le Mans — in June, as well as at Donington Park in England and at Spa in Belgium later this year. The car has already run a six-hour full-race-pace trial at the historic Goodwood track south of London to test its competition readiness. According to a history published in AutoEvolution, the original car was intolerably unreliable — it did not win any of the 12 races it entered – and was mightily inefficient. “At full steam, the Blower would burn four liters (1.1 gallons) of fuel every minute," the story said. "But its speed was the downright jaw-dropping act of the small, supercharged engine and the four-speed unsynchronized gearbox.” Several so-called Continuation Series Blowers have been commissioned and have been or will be built for sales to customers. All have already been already sold, with few modifications for modern safety, including a rain light and a fire extinguisher. Autoblog contributor Andrew English has driven the $2 million Car Zero, and it's a hell of a tale. A photo gallery of his exploits appears below. About three years ago, Bentley initiated the process of rebuilding the replica of the original Blower with a laser scan of all its parts. Engineers spent about 40,000 hours on the project, using original drawings and blueprints to create “high-fidelity copies” of the original parts. Nor was the interior ignored. Bentley used 22 pounds of horsehair to stuff the seats, the frame is made from ash, and the upholstery is red leather. ItÂ’s still, after all, a Bentley. Bentley Continuation View 13 Photos  

2015 Bentley Mulsanne Speed

Why does the Bentley Mulsanne Speed exist? Sam Graham, product line director for the Mulsanne, tells us Bentley's Western customers demanded it, many driven by memories of the Arnage T - the hotted-up version of the Arnage R. The Arnage T, you may remember, arrived in 2002 and threw down 459 horsepower and 645 pound-feet of torque on its way to being billed the most powerful production Bentley ever. Today's Mulsanne Speed picks up the torch and takes it all the way to the Olympic stadium.
Driving Notes
It starts with an upgrade to 530 hp at 4,200 rpm and 811 lb-ft of torque at a limbo-esque 1,750 rpm. That's an additional 25 hp and 86 lb-ft compared to the standard sedan, enabling a top speed of 190 miles per hour. That torque figure makes it second only to the Bugatti Veyron among production cars, and that terminal velocity makes it the fastest ultra-luxury sedan on God's Own Green.
