Rolls-Royce builds the Sweptail, a beautiful one-off boattail coupe

When it comes to custom-built cars, Rolls-Royce rarely fails to impress. Its latest creation is this one-off coupe called the Sweptail. According to Rolls-Royce, it was commissioned by a collector of bespoke machinery, and the car's design inspiration was the coachbuilt Rolls-Royces of the 1920s. The end result is an enormous Rolls-Royce coupe with a beautiful trailing boattail design. It looks like a hyper-expensive boattail Buick Riviera in the best way possible. A glass roof sheds light on a particularly plush interior. There are only two seats in the massive coupe. Where rear seats would have gone, are shelves made of wood and glass for storage. Wood veneer, consisting of ebony and paldao, is found everywhere in the car, even in the cargo areas. The darker wood trim is also accompanied by light colored leather. The Sweptail has a few little tricks up its sleeve, too. Opening the suicide doors on either side will reveal platforms for attache cases. The cases are designed to carry the occupants' laptop computers, and they're constructed from carbon fiber, wrapped in leather, and finished with aluminum and titanium hardware. Between the seats is a chiller that comes complete with crystal champagne flutes and a bottle of champagne from the year the owner was born. The trunk is also filled with custom-fitted luggage. Being a one-off, you won't be able to buy one of these coupes yourself. But it does show the capabilities of Rolls-Royce for doing special automobiles. And, who knows, if you have the money and connections, you might be able to have your own unique Rolls-Royce commissioned.

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).

Rolls-Royce debuts Phantom Drophead Coupe Waterspeed Collection

For the next act in its Bespoke Collection, Rolls-Royce has found one of its own to celebrate with the Phantom Drophead Coupé Waterspeed Collection, noting the achievements of British land and water record-holder Sir Malcolm Campbell. Like a few other racers of his era in the 1920s and 1930s, Campbell used his Bluebird Motor Company and Bluebird Garage to fund his interest in motorsports. He would break the waterspeed record in 1937 in his Bluebird K3 powered by a Rolls-Royce R engine, traveling 126.33 miles per hour on Italy's Lake Maggiore.
We've seen sketches of what Rolls-Royce intended with the Waterspeed Collection, and the real thing is just as handsome, and the new model includes a number of firsts for the marque. The Maggiore Blue exterior paint is also used for highlights on the engine, the polished wheels, two-tone steering wheel and the dashboard. The tonneau cover normally finished in teak is instead done in hand-finished brushed steel, a closer contrast to the Windchill Grey interior. The Abachi wood veneers have also been bookmatched so that their grain evokes the wake of a speeding boat.
The droptop will be shown first at the Bluebird Garage Cafe in London on the site of the original garage, after which it will get its first wider showing at the Concorso D'Eleganza at Villa D'Este later this month. The press release below has a lot more detail on the finer detailing of the Drophead Coupe Waterspeed, and the images above are worth at least 8,000 words.
