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).

This is why we love the Porsche 911 reimagined by Singer

In the world of restomods, Singer Vehicle Designs is inarguably one of our absolute favorites. The company, founded by rocker Rob Dickinson, has made its name as an obsessive constructor of vintage, built-to-order Porsche 911s with modern internals and beautiful accouterments.
Xcar has put together a lengthy interview with Dickinson, covering the source of his fascination with the 911 and his passion for automotive design, before falling into his rock-and-roll days with his band Catherine Wheel. He also covers how he got into the world of modifying Porsches, rather than just restoring them. There's much, much more in the video, though, and we promise, you won't want to miss it.
Take a look.

Porsche 911 GT1 Evo up for grabs in Monaco valued at $3M

On paper, Porsche didn't do a flagship supercar in between the 959 and the Carrera GT. In reality, it did. Sort of. It was the strassenversion of the 911 GT1, a homologation special based on a spectacularly successful racing car. And RM Sotheby's has a standout example consigned for its upcoming sale in Monaco. What you're looking at is a 911 GT1 Evolution that served as the mid-point in the GT1's development, following the original and followed in turn by the GT1-98 that won the 24 Hours of Le Mans that year. One of just fourteen 911 GT1s held in public hands, chassis number GT1 993-117 won the Canadian GT Championship three years running, and is the only GT1 Evo that was ever registered for use on public roads. RM Sotheby's anticipates that it will fetch between $2.9 and $3.25 million when it crosses the auction block in May, marking the first time that this particular example has come up for auction. That would make it considerably more valuable than the GT1 Evo Gooding & Company sold at Amelia Island in 2012 for $1.26 million, according to Sports Car Market. Of course, the Porsche isn't the only notable item the auction house has lined up for the sale during the Grand Prix de Monaco Historique weekend. There's a pair of 1930s German convertibles – one Mercedes 540 K and one Horch 670 – valued at about the same level as the 911 GT1, a Tucker 48 (~$1.6m), and Niki Lauda's debut March 711 grand prix racer (~$550k). Those are some tempting sets of wheels, and we'll be watching to see how they fare two months from now.
