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!"

Motor Trend puts Chevy Camaro Z28 and Porsche 911 GT3 Head 2 Head

Motor Trend admits, "This is an unfair comparison." But that doesn't make it any less fun to watch when they pit a Camaro Z/28 against the Porsche 911 GT3. The former has a 7.0-liter V8 with 505 horsepower and 481 pound-feet of torque shifted through a six-speed manual. The latter has a 3.8-liter flat-six with 475 hp and 324 lb-ft shifted through a seven-speed dual-clutch transmission. Yet those are only the little disparities – the big disparities are mass and money: the Camaro weighs 3,882 pounds and costs $76,150 as-tested, the Porsche weighs 3,267 pounds and costs $145,785. But they're both about hardcore performance, so MT takes them out on the street, to the drag strip, to the parking lot for figure eights and a skidpad test, and finally to Big Willow for Randy Pobst to give his professional assessment. Remember when a lotta people spent a lotta time debating Pirates vs. Ninjas? This is like that, only it's the "haul-ass good-time car" vs. the "track surgeon." Enjoy the debate in the video.

Chevy Volt beats Nissan Leaf again in February

For Chevy, February was a good month for Volt sales. They were up 62.5 percent compared to 2015, as the company locked in 1,126 sales. No one should be surprised, since buyers have a new generation Volt to look at on the lot this year. It was introduced late last year in just 11 states, with the nationwide roll-out not happening until this spring. Nonetheless, GM put the new Volt on sale in the states where it sold the most first-gen Volts, so the sales increase was totally expected. Year-to-date, Volt sales are up 71.8 percent: 2,122 for 2016 vs. 1,235 for January and February of 2015. Over in the Nissan lot, things look pretty much the same. By that I mean both the numbers (steadily down, recently) as well as the car itself. We've had numerous hints about a new Leaf, but nothing confirmed, and that means that fewer and fewer people are interested in the aging first-gen model. By the numbers, Nissan sold 930 Leaf EVs in the US last month, down 22.4 percent from the 1,198 it sold in February 2015. For the first two months of the year, Leaf sales are down 25.7 percent: 1,685 in 2016 compared to 2,268 in 2015. As always, we follow up our flash sales report for the Volt and Leaf with a more in-depth look at all the green cars sold in the US last month. Look for that soon, and discuss the latest numbers – which are a lot like the not-as-late numbers – in the Comments. Related Video: Green Chevrolet Nissan Electric Hybrid ev sales hybrid sales
