2015 Bentley Mulsanne Speed unleashes a tidal wave of torque

811 lb-ft of torque puts the Mulsanne Speed out ahead of every so-called muscle car on the market and eclipses most million-dollar hypercars.
Those in the market for a sedan with equal levels of performance and luxury would do well to stop by their local Bentley dealership, and have a look at the Flying Spur. Though not available in Speed trim like the previous four-door Continental, the W12 model already packs the 616-horsepower 6.0-liter twin-turbo W12 from the Continental GT Speed - and we wouldn't be surprised to see the British automaker come out with an even more performance-oriented version in the future. But what about the Mulsanne?

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.

Bentley unveils the Grand Convertible, a droptop Mulsanne Speed

Five years ago, when Bentley was preparing its farewell shindig for the Arnage, reports were that the Arnage's coupe and convertible siblings, the Brooklands and Azure, would get replacements on the Mulsanne platform. Obviously, that hasn't happened, although we were teased with the Mulsanne Vision Concept in 2012. Then, just this summer, we were again teased with rumors of a Brooklands and Azure one-two punch. While it still hasn't happened yet, Bentley's unveiling of the Grand Convertible seems to have put things in gear.
Not 'merely' a roofless Mulsanne, the Grand Convertible appears to be a droptop Mulsanne Speed, powered by a 6.75-liter engine with 530 horsepower and 811 pound-feet of torque, and fitted with the directional wheels only available on the Mulsanne Speed. Finished outside in Sequin Blue with a "liquid metal" hood and windshield frame and a burl walnut veneer on the tonneau cover - a similar combo used to introduce the Rolls-Royce Phantom Drophead Coupé eight years ago - the cabin is covered in Beluga leather with blue cross-stitching.
Company CEO Wolfgang Dürheimer says Bentley is watching customer reaction to the car, yet the press release says it's been "Developed to signify Bentley's intentions for the future." That sounds like better than even odds we'll be seeing this on the roads. For now, though, you can see it in the high-res gallery above, at the LA Auto Show starting this week, and at Art Basel in Miami after that, and you'll find a bit more info on it in the press release below.
