2017 Bentley Mulsanne defines the latest in handcrafted luxury

It takes 144 craftsmen roughly 399 hours to build a Bentley Mulsanne. In today's world of automation and just-in-time parts delivery, such statistics sound ridiculous. But this old-school approach to vehicle assembly earns this beast its status as Bentley's flagship. It takes about a third of that time to assemble a Continental GT, for instance, which is one reason the Mulsanne is so expensive. It's also why Bentley moves more than five Continental models for every Mulsanne it sells. Bentley has a brand-new crown jewel coming soon to dealerships as a 2017 model, and it will debut next week at the 2016 Geneva Motor Show. An Extended Wheelbase version joins the base Mulsanne and the Speed, pushing the lineup to three for the first time. Although Bentley officials take pride in the fact they are the largest producer of 12-cylinder engines in the world, the Mulsanne continues to soldier forth with the long-serving 6.75-liter V8. While this L-Series engine traces its roots all the way back to 1959, as evidenced by its cam-in-block overhead-valve design, it's been fully modernized with electronic controls and twin turbochargers. The result is 505 horsepower and 752 pound-feet of torque (or 530 hp and 811 lb-ft in the Speed), routed through a ZF eight-speed automatic transmission to the rear wheels. This is the same engine that has powered flagship Bentleys since 2010, and it's effortlessly capable of pushing the Mulsanne from 0-60 in 5.1 seconds and all the way up to a top speed of 184 miles per hour. The upgraded Mulsanne Speed improves those figures to 4.8 seconds and 190 mph. That's plenty of performance for this kind of vehicle, weighing as it does nearly 6,000 pounds. With that kind of power and heft, a solid chassis is a must. Active engine mounts join new suspension bushings for 2017, and the air suspension system has been updated. Continuous Damping Control and a Drive Dynamics Control System with three factory and one custom setting are standard. Also new are tires codeveloped with Dunlop that have foam-filled cavities to reduce interior cabin noise. Where the styling of the outgoing Mulsanne is smooth and stately, the new one is more angular and modern. At the front, the traditional upright grille remains, but it's over three inches wider than before, and is slatted with vertical vanes in polished stainless steel that are meant to recall Bentley classics from the 1930s.

2015 Bentley Continental GT3-R First Drive [w/video]

Racecars break. F1, NASCAR, IndyCar, GT3 – you name it – every go-fast machine built for the track is living on borrowed time. So it wasn't a complete surprise when, after traveling halfway around the world to drive Bentley's Continental GT3 racecar, the darn thing unceremoniously blew its rear differential on someone else's hot lap. While mentally recalibrating to the idea that my only takeaway from the three day commitment might be frequent flier miles, I realized an alternate vehicle on hand could make the trip worthwhile: the roadgoing, not-so-evil twin to the all-out race machine, the 2015 Bentley Continental GT3-R. You can hardly blame Bentley for the failure to proceed. The Flying B has been performing swimmingly well in the Blancpain Endurance Series, scoring three wins in its debut season and racking up a respectable 2015 so far. The dropped, spoilered, and severely trimmed-down GT3 racer reflects a ruthless abandon of all things luxurious and civilized. Over 50 ECUs were ditched from the road car; the doors alone, which typically weigh a lofty 125 pounds apiece, have been trimmed down to a wispy 15. Yes, the race version is a fearsome, sexy beast – and yes, this was quickly proving irrelevant because that drive was simply not meant to be.The Next Best Thing It's hard to call a $339,725 exotic a consolation prize. Climbing into the roadgoing GT3-R reveals a dramatic departure from the standard issue Conti: Not only is the color scheme unexpected (acid green on black and grey), so is the choice of materials (carbon fiber, Alcantara, not an inch of wood veneer in sight). Some pesky legacy remnants remain (antiquated navigation system, some weirdly pedestrian VW-sourced buttons and switches), but there's also a smattering of sweet details (those famous organ stop air vents, the green center indicator on the steering wheel, the pleasantly gripped Alcantara shifter). In all, 300 examples are being built, 99 of which are destined for the US. Unlike the somewhat sonorous GT V8 S upon which it's based, the GT3-R's titanium exhaust enables an even more exuberant, unapologetic, voluminous roar. Those exhaust gases are summoned from the 592-horsepower, 553-pound-foot, twin-turbocharged 4.0-liter V8, which gains 71 hp and 51 lb-ft over the V8 S model it's based on.

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:
