Dodge Challenger returns to Trans Am

NASCAR's Nationwide Series may have switched (in appearance anyway) to muscle cars, but American racing fans know that if they want to see real muscle cars on the street circuits, the only place to look is Trans Am. The all-American racing series is packed with Mustangs, Camaros and even Corvettes. The one thing it's been missing is the Dodge Challenger, but now SRT Motorsports has announced it's bringing its muscle car back where it belongs.
Rather than waiting until next year, the Miller Racing team is switching mid-season to the new Dodge Challenger SRT Trans Am racer you see here, just in time for this weekend's race at Mid-Ohio. And not just that - it's lined up a compelling pair of drivers to pilot it, as well.
The No. 11 car will be driven by Trans Am legend Tommy Kendall, a four-time series champion who's been off the grid since 2004. Backing him up in the No. 1 Challenger will be none other than Cameron Lawrence, the driver who has won five out of six races in the Chevy Camaro so far this season, losing out only once to American racing scion Adam Andretti.

2015 Dodge Challenger looks fresh, still plenty retro [w/video]

It was the Ford Mustang that kicked off the retro-styled muscle car renaissance back in 2005, but it was the Dodge Challenger that served as the movement's poster child, with its unabashedly retro looks. Over the years, though, as the Mustang and the Chevrolet Camaro were freshened and upgraded, the look of the big Dodge has remained largely consistent since its 2008 debut. For 2015, the Challenger has received a big freshening, boasting strongly revised front and rear ends and (finally, finally, finally) a redesigned interior.
Let's talk about that new cabin first. It's basically been plucked directly from the redesigned Charger, and boasts the same seven-inch IP display. The center stack's miserable, last-gen display has been replaced by an expansive, 8.4-inch UConnect system. Material quality should see a solid boost with the new cabin, as well.
The exterior, meanwhile, sees a revised front fascia with LED halo lights, as well as new grille inserts. A functional shaker hood scoop is a must-have extra on the V8 models, while the back of the car is highlighted by a new set of LED taillights that don't use the "Racetrack" design of Dodge's other models.

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!"
