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).

Diesel Power finds the ultimate modified oil-burner

For nine years, Diesel Power magazine has run the Diesel Power Challenge, this year's grindfest being "a week-long torture test that features seven events, nine trucks, 8,000 horsepower, and nearly 15,000 pound-feet of torque." The road to being crowned "the most powerful truck" starts with a dyno run, and then continues through the completion of a CDL-style obstacle course, an eighth-of-a-mile drag race while towing a 10,000-pound trailer, a quarter-mile drag race without a trailer, a fuel economy test in the mountains and finally a sled-pulling test through a 300-foot-long packed-mud pit.
What kind of trucks get into such a fight? Last year's winner, for instance - who upgraded his truck this year to prove he didn't "luck into the win" - drives a 2008 Ford F-250 Super Duty with a 6.4-liter Power Stroke V8 upgraded with a custom intake, Elite Diesel triple turbos and a two-stage nitrous system. Another competitor has a 2005 Dodge Ram 2500 powered by a 5.9-liter Cummins inline-six, upgraded with Garrett turbos, dual-stage nitrous, a seven-inch exhaust stack and twin fans built into the bed to cool the Sun Coast Omega transmission. The numbers on that truck: 1,255 horsepower, and 2,063 pound-feet of torque at the wheels. Naturally, as the image above might suggest, things don't always end well.
You'll find all five videos covering this years challenge below. A scene in the dyno video sums it all up perfectly: a competitor leaves his nitrous on too long and the crew is treated to some ominous poppings, he leans out the window, throws both hands up and shouts, "Amer'ca!"

2019 Dodge Challenger R/T Scat Pack Widebody Drivers' Notes | Widebody for everybody

The 2019 and soon to be 2020 Dodge Challenger R/T Scat Pack Widebody is another Challenger dart thrown against the wall by Dodge. It takes the desirable Widebody package we’ve seen on Hellcats and applies it to the naturally aspirated Scat Pack with the 6.4-liter V8. This kit includes stiffer adaptive shocks, stiffer springs, larger stabilizer bars, big Brembo brakes, a 3.09 rear axle ratio, 20-inch forged wheels and massive 305 section-width tires on all four corners. Most important of all, you get the special Widebody fender flares that give the car its signature look. The package is $6,000 on top of a regular Scat Pack. That means the cheapest youÂ’ll step into a Scat Pack Widebody is $46,740. The Widebody that rolled through our offices came in at a much-higher $57,295 after a number of options were tacked on. Many of these, you can skip. The 485 horsepower and 475 pound-feet of torque that comes standard is the most important aspect of this big coupe. Several packages costing more than $1,000 each add convenience and driver assistance tech, and the Harman/Kardon system is a hefty $1,595. With such a loud engine and exhaust, itÂ’s hardly worthwhile. Our tester also had the $1,595 eight-speed automatic transmission. ThisÂ’ll let you scare unsuspecting bystanders with the remote start system, but opting for a manual is an easy way to save some cash and increase driver involvement. With all the modern technology like adaptive cruise control, auto high-beams, heated and cooled seats, and blind-spot detection, the Challenger tries its best to keep up with the times. ItÂ’s no technological marvel, but itÂ’s neat to see some of these options available for folks who might want them. Still, tech gizmos are not what the Widebody is about. This Challenger keeps the same personality as all of those before it, but adds a dash of handling and hostility to its outward appearance. Here are our varied experiences with it during a week of testing. Editor-in-Chief, Greg Migliore: Yes, you can put a rear-facing convertible car seat in a Dodge Challenger. I did. It actually wasnÂ’t that hard. Remember, the Challenger is genetically a Mercedes sedan and shares underpinnings with the Dodge Charger. The biggest hurdles are ingress and egress, which is to be expected in any coupe. The roofline is low, but really not that bad. I simply lifted my toddler and maneuvered him into the backseat.  I was able to get him secured and fastened, and then I just stepped out of the car.
