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!"

New Viper 'is a possibility,' Sergio Marchionne says

It was thought the door to the future for the Dodge Viper had closed last year, but Fiat Chrysler CEO Sergio Marchionne reopened it during his press conference at the 2016 Detroit Auto Show. Marchionne said the current Viper is the only FCA product to use the ZD platform, which "doesn't make sense to me." Yet, "given the architectural development within the brand, there is a possibility that a new version of the Viper may surface." Automobile reports that the company uses a versatile, rear- and all-wheel drive Giorgio platform for Alfa Romeo and Dodge. It will support the Alfa Romeo Giulia (Alfa Romeo's larger BMW 5 Series competitor), the next-generation Dodge Challenger, Charger, and rumored Barracuda, and it could support a new generation of Viper. We're probably talking about a different kind of Viper, though, with Automobile saying, "the current car's truck-based V-10 no doubt would be scrapped along with its platform." A Viper without a V10 doesn't seem like a Viper to us, but we'll wait to see what happens. In the midst of contract negotiations for a new labor agreement between FCA and the United Auto Workers last year, it emerged that the Conner Avenue Assembly plant that builds the Viper hadn't been given any new product after the end of Viper build-out in 2017. That led most to reason that the current Viper would be the end of the 25-year run of America's hairiest sports car. How long we'll be waiting is unknown. Marchionne had no timetable and admitted that a future Viper might not appear on the heels of the current one. With a renewed commitment to being debt-free by 2018, FCA is likely more focused on getting Alfa Romeo running properly and cranking out the volume variants for the Giorgio platform first.

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).
