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 reserves 99 Continental GT3-Rs for North America at $337k apiece

Whether they're powered by V8 or W12 engines, the Bentley Continental GT just keeps getting faster and faster. The new Continental GT Speed, for example, is the fastest road-going Bentley ever made, capable of reaching 206 miles per hour. And the Continental GT3-R is the quickest-accelerating Bentley yet, capable of hitting 60 in just 3.6 seconds.
In other words, if you want to get your hands on one, you'll need to act fast. Bentley is only making 300 examples of the GT3-R, but while it is said to have already sold out the entire production run, it has been kind enough to keep 99 examples on the side just for the North American market.
The road-going embodiment of the Continental GT3 racer, the GT3-R packs a 4.0-liter twin-turbo V8 tuned up to 572 horsepower and 516 pound-feet of torque. That makes it 72 hp and 29 lb-ft stronger than the base Continental GT V8, or 43 hp and 14 lb-ft more muscular than the GT V8 S, about on par with the W12 model but 54 hp and 89 lb-ft shy of the latest GT Speed. But thanks to its lighter weight (inherent in the eight-cylinder model and stripped of a further 220 pounds in the GT3-R), it trounces them all in the sprint to 60.

Top horsepower-per-dollar cars in 2017

Bang for the buck. That quasi-scientific statistic is bandied about by motor heads everywhere from classrooms to barrooms, though the truth of the matter is that it's exceedingly complex to measure. A fair performance-per-dollar index would include something like cross-referencing MSRP (Manufacturers Suggested Retail Price) with point-to-point times on a track or driving route, which is obviously hard to do comprehensively. But, for the sheer joy of talking about cars and playing with a big spreadsheet, there's always the horsepower-per-dollar index, which is more straightforward, albeit hilariously flawed. There are vagaries even with this simple formula, of course: MSRP for vehicles can change at a moment's notice, to say nothing of the bottom-line shifting that happens with local deals or showroom negotiation. For this list we're running with the straight MSRP wherever possible, and as recently reported as we can get it. All the vehicles on this list are 2017 models, and all trims are reported where the lowest price and differing power levels intersect. Some choices were made for personal preference and some for sanity, avoiding things like all 48 trim levels of the Ford Transit, all with the same horsepower). If this list were a simple top ten, or even a top fifty, you'd be bored to tears with all the red, white and blue that is represented. Following perfectly with conventional wisdom, American cars really do lead the world where hp/$ is concerned. So, for the sake of variety (and the sheer joy of seeing a minivan 'win' one round of this thing) I've sorted out some top five and bottom five lists for broad power categories. Let's dive in. Less Than 100 Horsepower Okay, okay, this is hardly a category we'll grant you. But we've often tried to click off all the sub-100-hp cars on sale in the US, and making this list gave us an excuse. It also illustrates that none of these smallish vehicles bring cheap horsepower to the table - for that you'll need a motorcycle. The segment-leading Chevy Spark (above) asks just over $139 for each hp, and that Smart Fortwo Electric Drive has hp on sale for about the same price as its very distant family cousin, the Mercedes-Benz SL65 AMG (insert your favorite Smart joke here... we know you want to).
