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 courting Maybach celebs with letter-writing campaign

When Daimler let slip that Maybach was on the chopping block, the German automaker reportedly insisted that ultra-luxury editions of the Mercedes-Benz S-Class would replace the doomed marque. We're all for a smattering of low volume, seriously pricey S-Class variants, but will the richest and most influential Maybach buyers feel the same way?
Automotive News reports that Bentley is betting that stars like Jay-Z and Samuel L. Jackson will want more than a gussied-up Benz, and the luxury car make is sending out olive branches in the form of a letter campaign. The premium Volkswagen brand is asking the high-rollers to step into a Bentley Mulsanne or perhaps a top-shelf Continental GT. To help persuade VIPs to switch to Bentley, the automaker is inviting select Maybach owners to tour its Crewe, England home.
Given the fact that many typical soccer moms and dads can afford an ML-Class, we can see why some movie stars and sultans would want to steer clear of the Three-Pointed Star. But is Bentley really going to gain much by wooing the 200 annual Maybach buyers? If a few more rap stars roll in a Bentley in their next music video, then the answer would appear to be yes.

A diesel V8 is the perfect engine for the Bentley Bentayga

Endless, effortless torque is something that's so often taken for granted. Sure, horsepower figures make all the headlines, but the sensation that comes with immediate and readily available thrust is something that can't be overstated, especially in luxury vehicles. High-strung, high-horsepower engines are great in certain applications, but Bentley owners don't want to work for the power, they just expect it to be there. That's why the 4.0-liter diesel V8 from the Audi SQ7 and its 664 lb-ft of torque make perfect sense for the new Bentley Bentayga. We've known for a while that Bentley is planning a diesel variant of the Bentayga, but it wasn't clear from where the engine was being sourced. According to Telegraaf in Holland, Bentley is pulling the diesel from the heart of its sibling Audi, and it won't be an effort to improve fuel efficiency. The all engine features two exhaust-driven turbos plus a 48-volt compressor that effectively cuts lag to nothing and propels the SQ7 TDI to 62 mph in 4.8 seconds. Expect a similar number in the Bentley. This engine is exactly what the Bentayga needs. There is nothing wrong with the W12 in the standard model, and you could argue a 12-cylinder engine is a better fit in a Bentley. But that's just because W12 sounds better than diesel. While the gasoline engine may more powerful and therefore make the vehicle quicker (leading to that " fastest SUV" claim Bentley loves), no owner will actually be racing their Bentayga to its theoretical top speed of 187 mph. They will be racing away from stoplights, though, in an effort to leave more plebeian cars and SUVs behind. All that low-end grunt is what those owners really want. It's unclear if Bentley will bring the Bentayga diesel to the United States, and given the current state of diesel here, the proposition seems unlikely. Expect an official debut at the Paris motor show in October. Related Video: News Source: Telegraaf Rumormill Bentley SUV Diesel Vehicles Luxury bentley bentayga audi sq7
