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).

McLaren offers glimpse inside P1 GTR program [w/video]

Among the many things we were looking forward to seeing at Pebble Beach this year, the McLaren P1 GTR was near the top of our list. Invoking the spirit of the legendary McLaren F1 GTR that dominated sports car racing in the mid-1990s, the P1 GTR was unveiled in Monterey this past August in concept form, giving us an idea of what to expect. But now McLaren has given us a little more. Envisioned as a track toy for the wealthy who want to play racing driver, the P1 GTR is a further evolution – and a more extreme one – of the road-going P1. The GTR is being developed exclusively for use on track. To that end, Woking has stripped out the cockpit and installed a multifunction steering wheel said to be derived from the championship-winning MP4-23 grand prix car, allowing the driver to "fully adjust the setup and characteristics of the car without having to take their hands off the wheel." The racing buckets are modeled after a DTM touring car, equipped with six-point harnesses and affixed directly to the chassis. Outside you'll notice Pirelli slicks and a fixed rear wing with F1-style Drag Reduction System. The P1 GTR is about more than the vehicle itself, though, as McLaren – similar to what Ferrari offers with the XX client test-driver program – is launching a full driver support program to go along with it. Customers will have access to the advanced simulator at the McLaren Technology Centre (typically reserved for the team's contracted racing drivers) as well as the factory's coaches. The program will also include 10 to 12 track sessions each year, to be held at F1-certified tracks around the world, at which each customer will have his or her own garage and crew, all for the benefit of their enjoyment. The program is laid out in the video below, along with which McLaren has released a fresh batch of images showing the uncamouflaged prototype inside and out undergoing hot-weather testing at the grand prix circuit in Bahrain.

McLaren planning P13 GT with unconventional trunk

It was just a couple of months ago that we last brought you word on P13, the project being undertaken by McLaren to slot in a new entry-level model below the above-pictured 650S. Speaking with McLaren personnel at the launch of the latter, we said that the P13 would come in multiple bodystyles – which is to say, more than just a coupe and convertible. Now Car and Driver says it knows what that third bodystyle will be. According to an unnamed inside source in Woking, C/D reports that, in addition to a two-seat coupe and Spider, the P13 (or whatever it's ultimately called for public consumption) will be offered as a GT model. And just what will the difference be between the coupe and GT, you ask? Not necessarily the addition of extra seats in the back: according to Car and Driver, that will be a luggage compartment aft of the engine and passenger compartment. The resulting form, we understand, will resemble a Jaguar E-Type coupe, which could be what we were actually hearing about a couple of years ago when rumors surfaced of a 12C shooting brake in the works. One way or another, it would be an interesting development, potentially as novel as the Ferrari FF but at the opposite end of the spectrum and with its 3.8-liter twin-turbo V8 – albeit slightly detuned – still located amidships and still driving the rear wheels through a seven-speed DCT. We'll just have to wait and see how it turns out, but with Frank Stephenson working on the design, we bet it'll be a stunner, if a slightly unconventional one.
