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 shifting W12 engine production to UK

Who would you think would be the largest producer of 12-cylinder engines in the world? Mercedes? BMW? Ferrari? Think again: as you might have guessed from the headline, it's Bentley. The thing is that, while all Bentley automobiles are manufactured in the UK, its engines aren't: while the 6.75-liter V8 in the Mulsanne is made at home, the innovative 6.0-liter twin-turbo W12 engine in Continental models so equipped (like the newer 4.0-liter twin-turbo V8) is shipped in from Germany. But that won't be the case any longer.
Bentley has just announced that production of the W12 engine is moving to its home base in Crewe by the end of this year. The shift in production (which follows the migration of the Flying Spur from Dresden to Crewe in 2007) will create 100 jobs in the UK - a country which employs some 142,000 workers in the automotive sector - and produce as many as 9,000 engines per year. That in and of itself would account for the vast majority of the 10,000-plus cars Bentley made last year, but will also make Bentley an exporter of engines for the first time in its history.
Right there at the factory, Bentley will fit the engines into twelve-cylinder versions of the Continental GT, GTC and Flying Spur, and send some back to Germany for use in the Audi A8. Applications within the Volkswagen brand itself like the Phaeton and Touareg no longer use the W12 engine, but could conceivably use it again in the future - they'll just have to bring them in from England is all.

High-end Bentley Bentayga Apex adds weight-saving carbon goodies, plus nice pinstripes

  Bentley is going on a carbon binge, by introducing the Bentayga Apex Edition, developed by its in-house Mulliner bespoke division and advertised as the Ñ’most dynamic-looking and driving Bentayga ever.Ò’ What’s novel about this crossover, which will be limited globally to only 20 units, is its reliance down low on lighter-weight carbon: 22-inch carbon rims that save a significant six kilograms each in unsprung mass over the standard items. And slotted behind those wheels, a set of carbon silicon discs, which Bentley says can offer improved braking performance, survive temperatures of up to 1,000 degrees, and shave another 20 kilos of weight compared to iron rotors. By employing weight reduction materials, the luxury British brand claims the Apex models achieve improved steering agility — that a carbon wheel does not flex on the road — as well as better braking response and less tire wear. As far as fashion elements for the limited-edition Apex, well-heeled customers will be able to choose from six ‘curated themes by Mulliner,” including Extreme Silver with Beluga stripe and Signal Yellow pinstripes, Pale Brodgar with Anthracite stripe and Bacalar bronze pinstriping, and Alpine Green with matching stripe and orange pinstripe. WeÂ’re especially enticed by Theme 1, comprised of an exterior in Candy Red satin, with a livery of Anthracite and Arctic White stripe and pinstripes in Arctic White. Bentley describes the interior thusly: “Arctic White main hide and Hotspur secondary hide are complemented by Arctic White contrast stitching and seat piping. This contrast colour can also be found framing the satin carbon fibre fascia and waistrails.” Design aside, the Apex Edition is based on the Bentayga S, which houses a 550-horsepower twin-turbo V8 with a top speed of 180 mph, with rear axle steering and active anti-roll technology. Most drivers would probably be satisfied with the common S model, which retails at a starting price of about $220,000. No pricing or availability for the Apex editions have yet been announced.
