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:    

Your Bentley interior can literally rock with stone trim

The ultra-luxury car market has been moving in the direction of ever more customization to provide buyers the most unique products possible. The latest move comes from Bentley and its Mulliner division, which has added some special interior trims to the existing line of gloss wood. Now buyers with the means can finish their Bentley interiors in open-pore wood, carbon fiber, aluminum, color-matched paint and even stone. The two most impressive interior trims are the stone and open-pore options. The stone veneers are made from slate and quartzite, and are available in four different colors: Autumn White, Copper, Galaxy, Terra Red or the Galaxy that's shown in the gallery above. In order to keep the stone from adding too much weight, the veneer is only 0.1 mm. It's also finished so that you can feel the texture of the rock. For the open-pore trim, Bentley offers three wood choices: Liquid Amber (made from American Red Gum), Dark Burr and Tamo Ash. Each has a unique grain that can be felt thanks to the 0.1-mm thick matte protective coating, which is a fifth the thickness of the gloss wood coating. The carbon fiber trim is pretty straightforward. It's gloss carbon fiber, though Bentley says the the resin it uses highlights the weave of the carbon. The aluminum is also fairly straightforward, featuring a thee-dimensional texture mirroring the grille of the car. The diamond-brushing is meant to emphasize the dimension to the panels. Interestingly, this option is exclusive to the Bentayga. Choosing painted trim gives owners the most variety in choice, since they can opt for any of Bentley's 88 exterior colors, or have the panels matched to the interior leather. Related Video:

Volkswagen Group previews its wares on eve of Geneva show

The Volkswagen Group is comprised of 11 brands producing 240 vehicles across 49 factories throughout the world. So the best way to show off the range of the VW family is to cram a few thousand journalists and VIPs into a massive makeshift stand to outline the Group's goals, what's in the pipeline and what you'll be able to buy later this year.
To that end, VW pulled out all the stops on the eve of the 2012 Geneva Motor Show, bringing along 10 vehicles from across the range. We'll be delving into the details of each over the next two days of show coverage, but before that happens, you can read all about what we saw tonight from the cheap seats after the break.
