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).

1985 Porsche 911 rally-style classic to be auctioned for good cause

Porsches are supposed to inhabit race tracks, winding roads, and wide, flashy boulevards, right? Not all of them. Take this 1985 911 Carrera, which was has been converted into a rally-style toy that we'd love to sample on a dusty, tree-lined section of dirt. Nicknamed #Luftauto, this lovely 911 is being auctioned off by RM Sothebys during Luftgekuhlt, an event dedicated to air-cooled Porsches and put together in part by Porsche racer Patrick Long. The car has been extensively modified, both aesthetically and in terms of outright performance. We're digging the 15-inch Braid wheels, custom rally lights, and an Auto Foreign Services roof rack on the exterior. The cabin gets a custom rollbar, but it's the driver interfaces we're really drooling over – there's an OMP steering wheel and a CNC-milled shift knob made of walnut and maple, while driver and passenger will be kept in their fancy Recaro seats by Schroth Rallye harnesses. The limited tweaks to the numbers-matching, 3.2-liter flat-six – the headers and exhaust have been swapped with SSi units – do wonders for the Porsche's already impressive soundtrack. The engine isn't a new unit, of course, but it's fresh off a major round of service. There are ample suspension mods, too, with a custom-designed KW setup and long-travel dampers. A cool car being put up for auction is exciting enough, but the profits from #Luftauto are going to something even cooler – cancer research. In particular, the money made will be donated to the Autumn Leaves Project, a charity that's dedicated to battling pancreatic cancer. For those not familiar, pancreatic cancer is one of the most despised, merciless forms of cancer around, infamous for its ability to remain undetected until it's far too late to combat. It's a truly hateful disease. You can check out #Luftauto in action in the video up top. It crosses the block on April 10 in Los Angeles. Additional details can be found at the Luftgekuhlt website.

2017 Porsche Panamera: Technical details of the world's fastest luxury sedan

In anticipation of our upcoming first drive of the new Porsche Panamera, here's an in-depth look at Stuttgart's new sedan. We already know what it looks like, but now we have details on the powertrain, chassis, and electronics. Let's jump right in. Engines, Transmission, Platform The big news is the all-new twin-turbo 4.0-liter V8 in the Panamera Turbo. It adopts a "hot vee" layout with the turbochargers in the engine's valley. This setup allows for a short run from the exhaust manifold for minimal lag, which is further reduced by the twin-scroll turbos. With 18.8 psi of peak boost, the new V8 pumps out 550 horsepower and 567 pound-feet of torque. As we mentioned, that's just 20 hp behind the outgoing Turbo S. And the Panamera Turbo is quick - good for 0 to 60 mph in 3.4 seconds with the Sport Chrono pack. Yes, launch control looks awesome. This is also the first Porsche engine to adopt cylinder deactivation - in four-cylinder mode the engine can run up to 3,500 rpm with as much as 123 horsepower. To shut down four cylinders at a time, the camshaft on each bank slides to engage a dummy lobe on cylinders two, three, five, and eight. When running in V4 mode, the valves stay closed on the shut-down cylinders. Another nod to emissions and efficiency is a catalytic converter mounted close up near the vee, right behind the turbos. All that heat requires airflow, so there's a dedicated duct from the radiator that routes fresh air over the turbos and catalytic converter. There's an all-new twin-turbo 2.9-liter V6 as well, made with the same 90-degree angle as the V8 because it's based on modular architecture. The V6 lacks cylinder deactivation but keeps the hot vee and adds two-stage variable lift on the intake valve. It is not lacking for power, with 440 hp and 405 lb-ft of torque. Both engines (and the European-market twin-turbo 4.0-liter V8 diesel) mate up to a new eight-speed dual-clutch automatic made by ZF. The new design is 5.6 inches shorter than the seven-speed it replaces and allows for an upcoming hybrid powertrain to be integrated without adding any extra length. The top three gears are overdrive ratios, with the top speed from both engines coming in sixth. Along with leading the development of the new V8, the Panamera is also the first car on the new MSB platform. That's Modularer Standardantriebs-Baukasten for you AP German students; a near-literal translation is modular standard drive.
