Bentley Continental GT3-R is a limited-edition racer for the street

Limited to just 300 examples worldwide, Bentley's new GT3-R is set to bring a bit of the brand's motorsports pedigree to the street. After all, the Flying B recently took the win at the Blancpain Endurance Series at Silverstone with its new Continental GT3, less than one year after the big racer's debut.
Like the road-going Conti GT, the GT3-R uses a twin-turbocharged 4.0-liter V8, tuned in this application to 572 horsepower and 516 pound-feet of torque - increases of 51 hp and 14 lb-ft from the already potent GT V8 S. That's enough to get the 4,839-pound Bentley to 60 miles per hour in just 3.6 seconds, on its way to a top end of 170 mph.
To make the GT3-R more hardcore than standard Continentals, the air suspension has been retuned, the brakes have been upgraded with carbon silicon discs, and there's a titanium exhaust that's good for 15 pounds of weight-savings - in all, the GT3-R is some 200 pounds lighter than a comparable GT V8 S.

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).

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.
