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!"

Are supercars becoming less special?

There's little doubt that we are currently enjoying the golden age of automotive performance. Dozens of different models on sale today make over 500 horsepower, and seven boast output in excess of 700 hp. Not long ago, that kind of capability was exclusive to supercars – vehicles whose rarity, performance focus, and requisite expense made them aspirational objects of desire to us mortals. But more than that, supercars have historically offered a unique driving experience, one which was bespoke to a particular model and could not be replicated elsewhere. But in recent years, even the low-volume players have been forced to find the efficiencies and economies of scale that formerly hadn't been a concern for them, and in turn the concept of the supercar as a unique entity unto itself is fading fast. The blame doesn't fall on one particular manufacturer nor a specific production technique. Instead, it's a confluence of different factors that are chipping away at the distinction of these vehicles. It's not all bad news – Lamborghini's platform sharing with Audi for the Gallardo and the R8 yielded a raging bull that was more reliable and easier to live with on a day-to-day basis, and as a result it went on to become the best-selling Lambo in the company's history. But it also came at the cost of some of the Italian's exclusivity when eerily familiar sights and sounds suddenly became available wearing an Audi badge. Even low-volume players have been forced to find economies of scale. Much of this comes out of necessity, of course. Aston Martin's recent deal with Mercedes-AMG points toward German hardware going under the hood and into the cabin of the upcoming DB11, and it's safe to assume that this was not a decision made lightly by the Brits, as the brand has built a reputation for the bespoke craftsmanship of its vehicles. There's little doubt that the DB11 will be a fine automobile, but the move does jeopardize some of the characteristic "specialness" that Astons are known for. Yet the world is certainly better off with new Aston Martins spliced with DNA from Mercedes-AMG rather than no new Astons at all, and the costs of developing cutting-edge drivetrains and user interfaces is a burden that's becoming increasingly difficult for smaller manufacturers to bear. Even Ferrari is poised to make some dramatic changes in the way it designs cars.

The Dodge Challenger plays its trump card: all-wheel drive

Perennially stuck in third place behind the Ford Mustang and Chevy Camaro in sales and enthusiast comparisons, the Dodge Challenger is doing something unconventional for a muscle couple. It's adding all-wheel drive. It's a new feature for Detroit's pony cars – none of the three have ever had it – and it could be a game-changer. Called the Challenger GT, the Dodge launches this winter for a starting price of $34,490. The Challenger GT comes with the Pentastar 3.6-liter V6 rated at 305 horsepower and 268 pound-feet of torque. It teams with an eight-speed TorqueFlight automatic transmission and is estimated to get 18 miles per gallon in the city and 27 mpg on the highway. An FCA spokesperson said no manual transmission or V8 models will be offered on the all-wheel-drive Challenger. It will be on display in January at the Detroit auto show.

The coupe shares underpinnings with the four-door Charger, which offers an all-wheel drive variant and the cars have similar powertrain offerings (the AWD Charger is also V6 and automatic only). Naturally, the Challenger borrows the Charger's AWD system and during regular driving conditions, the front axle disengages and full torque goes to the back wheels, allowing the Challenger to function as a rear-wheel drive car. It automatically goes back to AWD when more traction is needed. Handling is also fortified with a vehicle dynamic control system. Conversely, the electronic stability control has three modes and can be switched off for drift-happy enthusiasts. The GT has features familiar to other Challenger and Dodge owners, including an 8.4-inch touchscreen radio, Performance Pages (accessible through the Super Trak Pack button), and paddle shifters. A Sport Mode changes shift points to improve acceleration. It all rolls on 19-inch wheels wrapped in all-season rubber. The exterior gets a hood bulge, LED head- and taillights, and a decklid spoiler. The Challenger GT also offers a $995-interior package different than RWD models, adding Nappa leather, Alcantara suede seats, a nine-speaker Alpine audio system, performance steering wheel, and more. All of that is just window dressing. It's all-wheel drive that could be a difference-maker for consumers. The Challenger won't likely be able to take down the Mustang, which will finish 2016 as the pony car sales king.
