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!"

Car and Driver 10Best list cracked by Tesla Model S, BMW 3 Series left off

Car and Driver is keeping new blood pumping into its annual 10Best cars list with three new entries making it on for 2015 and a perennial favorite falling off. Among the biggest shocks this year is that the BMW 3 Series and 4 Series are no longer named, despite years of some portion of that lineup earning a mention. In another surprise, the Tesla Model S (specifically in S 60 trim to fit under the $80,000 cost cap) makes it to the 2015 roster and is the only electrically motivated member of the group. Despite the loss of the 3 Series, BMW isn't entirely shut out this year, because the M235i gets its name on the list. Car and Driver argues that the little coupe feels like a welcome throwback to the E46 chassis M3 of the early 2000s. In addition to the Model S, the final newbie to the annual group is the 2015 Ford Mustang GT. The inclusion of these new members knocks the Audi A6/A7 family and Ford Fiesta ST out from the 2014 rundown. The other seven models carry over from last year, including the Cadillac CTS, Chevrolet Corvette Stingray, Honda Accord, Mazda3, Mazda6, Porsche Boxster/Cayman and Volkswagen Golf/GTI. The 2015 10Best cars list certainly seems to have something for everyone from the hot hatch fan to the family man and even the green car driver, thanks to the addition of the Tesla. Head over to Car and Driver to read its detailed explanations for each vehicle's inclusion, but if you've got a difference of opinion or just really like the list, let us know in Comments.

First privately owned Corvette Stingray blitzes 1/4 mile in 12.23 at 114.88 mph

Chevrolet's latest road rocket, the Corvette Stingray, is a very quick car. If one needs further proof of that, we recommend they take a look at this video from Hennessey of what is claimed to be the first privately owned C7 Corvette to make a pass down the quarter mile. Not just any quarter mile, mind, this black C7 blitzed its way down the tuner's primary testing dragstrip. The Chevrolet ran the quarter in just 12.23 seconds at 114.88 miles per hour. That is a very quick time for a stock car.
Equipped with the Z51 package and a six-speed automatic transmission, not only does the C7 run a solid time, but it does so with little to no drama. That won't last though, as Hennessey will likely return it to its owner with far more power - we just hope they show a drag run of the completed product. Take a look below to watch the C7's 12.23-second run on video.
