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).

Porsche announces four flavors of updated Cayenne [w/video]

The new Macan may be getting all the attention lately, but Porsche hasn't forgotten about its larger crossover - the one that put it on the map in 2002 and on the road to profitability, with over half a million sold so far. So to keep the Cayenne at the top of its game, Porsche has announced several key upgrades for the 2015 model.
For starters, Porsche has updated the Cayenne's appearance with new front- and rear-end styling. The front bumper, fenders and hood are entirely new, with air fins flanking the nose to direct air into the intercoolers (each model now being artificially aspirated), and new bi-xenon headlamps and daytime running LEDs on every model but the Turbo, which goes all-LED. Around back there's also new taillights, tailgate handle, lower rear fascia and exhaust pipes. Meanwhile the interior has been upgraded with a 918-derived sport steering wheel and reformed rear seats with available ventilation.
The bigger news is under the engine bay, where Porsche is offering four choices. The base model is gone as the range starts with the Cayenne Diesel, followed by the Cayenne S, the new Cayenne S E-Hybrid and the top-of-the-line Cayenne Turbo. The Diesel model carries over the same 3.0-liter turbo diesel with 240 horsepower. The Cayenne S however packs a 3.6-liter twin-turbo V6 that's similar to the one found in the Macan Turbo and packs the same 406 lb-ft of torque but more power at 420 hp, 20 more than either its little brother or the model it replaces to reach 62 mph in 5.2 seconds.

Porsche 911 GT3 RS getting all-new atmospheric engine

Porsche surprised many of its most puritanical enthusiasts when it took a decidedly more usable approach with the current 911 GT3. But when the new GT3 RS debuts, it promises to be a much more extreme departure. And a big part of that comes down to the engine. At the Detroit Auto Show this week, Auto Express spoke with Porsche R&D chief Wolfgang Hatz – who also happens to be head of engine and transmission development for the entire Volkswagen group. Hatz revealed that Porsche has developed a completely new engine for the GT3 RS, and while previous rumors suggested the RS would go turbo to fill in for the lack of a GT2 (and make the most out of its displacement), Hatz confirmed that it will be naturally aspirated. Considering that Porsche rarely goes downwards when it comes to 911 engine displacement, only upwards, we'd expect the new RS to pick up where the previous 4.0 left off. The new GT3 RS is also expected to pack a more extreme suspension, aero and stripped-out interior, but those hoping for an old-school approach may be disappointed to learn that the new RS will (at least at launch) only be available with the seven-speed dual-clutch transmission – though a manual version could follow if there's enough demand. In a related development, Hatz also hinted that the Cayman GT4 could debut at the Geneva Motor Show in March, with an even more extreme approach than the previous Cayman R. The new top-of-the-line Cayman is reportedly being developed to comply with GT4 class racing regulations but be fully homologated for road use. Related Video:
