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).

Watch a Group B Porsche 911 tear up the 'Ring in the snow

The Nurburgring is a motorsports fantasyland during the best weather, but it looks even more exciting when the snow starts to fall. While the course isn't open to the general public during the winter, this Porsche 911 SC RS rally car managed a lap of the snow-covered Grand Prix Circuit, sliding the whole way around. The 911 SC RS isn't as famous as Porsche racers like the 917, but it has an interesting story. Porsche's development of the 959 was slow in the '80s, and this coupe was the company's stopgap for Group B rallying. The SC RS used the 911 Turbo's wider body, suspension, and brakes, but the car had a naturally aspirated 3.0-liter flat-six to drive the rear wheels. It couldn't compete against all-wheel drive beasts like the Audi Quattro, but one managed third place in the 1985 Tour de Corse in France. The SC RS sounds great in this video, and it looks even better kicking up snow. There's so much accumulation that you can't tell which way the track goes, but driver Patrick Simon knows his way around. After watching this clip, we think the 'Ring should unleash a few more old rally cars on the track for a new racing series next winter.

Jay Leno welcomes Emory's outlaw Porsche 356s

Classic cars can have a lot of character, but purposely passing up on some of the enormous advancements made to the automobile over the decades since those classics were made can be a difficult proposition. That's where restomodders like Emory Motorsports come in. Emory specializes in customizing Porsche 356s, modifying them to their clients' specifications and giving them an added dose of performance and refinement, all without losing that timeless appeal. The LA-based company is headed up today by third-generation Southern Californian gearhead Rod Emory. After seeing some examples of his work out on the road, Jay Leno invited Rod by the garage along with a pair of his company's custom creations. Both are based on 356 coupes from the late 1950s, but take pretty different approaches in their comprehensive restoration and extensive modification. Since classic Zuffenhausen enthusiasts are notorious for their rigid adherence to originality, Emory's modified 356s are deemed to be "outlaws" by many on the vintage Porsche scene. But they've also gained quite a following, similar to what Singer has done with 911s. Whether you're more inclined to cling to authenticity along with the purists or embrace the novelty espoused by the restomodders, after scoping out these irresistible specimens, you'll have to admit that Emory does some pretty compelling work. Watch the 25-minute video clip above to see what we mean, and check out Petrolicious' profile of the same company's work from last year for another look.
