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!"

Can Fernando Alonso win Indy? Here's why and why maybe not

SPEEDWAY, IN – The month of May has been a joy ride for Fernando Alonso at Indianapolis Motor Speedway. The two-time Formula 1 champion came to Indy having never turned left in a race car without also turning right. But he acquired such a feel for Indy's 2 1/2 -mile rectangle during a month of practice and qualifying that he's considered a strong contender to win the 101st Indianapolis 500 on Sunday, rookie or not. "You're not trying to bring somebody on who has very little experience driving very high-performance cars," said 2003 Indy 500 winner Gil deFerran, who this month has helped Alonso learn the nuances that make the speedway such a tough place to conquer. "I suppose it would be a little bit different if you were dealing with a younger, much less experienced person." Driving a McLaren Honda from the potent Andretti Autosport team, Alonso was consistently near the top of the speed charts in practice, he qualified fifth fastest at 231.300 mph, and he handled runs in heavy traffic like a driver who'd done it many times before. But those were the prelims. The race is another creature. "The car felt the best (it has) in the last two weeks. I was making some moves, taking some different lines. I am extremely happy." Other drivers say the speedway looks different on race day when the crowd, expected to top 300,000, fills the grandstands and makes an already narrow track seem even tighter. The three-wide rolling start is something Alonso has never experienced, and he will see the green flag from the middle of the second row between Takuma Sato and J.R. Hildebrand. And the space he'll be given by his competitors in the first 180 laps may disappear In the last 20 when it's every driver for themselves. Can a rookie like Alonso win this race? Absolutely, as Andretti driver Alexander Rossi showed last year when his team used a fuel-mileage strategy to win in his first taste of Indy. We're talking about Fernando Alonso here, who easily could show his rookie stripes to the rest of the field most of the day. His best lap in Friday's final practice, 226.608, was fifth fastest in the field and, more important, he said the car felt comfortable in heavy traffic. "The car felt the best (it has) in the last two weeks," Alonso said. "I was making some moves, taking some different lines.

GM claims it's first to sell million 30+ mpg vehicles

As we continue to put together all the data for the year-end edition of By The Numbers, General Motors has announced that it sold more than a million vehicles in the US last year that achieved at least 30 miles per gallon on the highway. More impressively, GM managed this feat using multiple strategies including small vehicle size, turbocharged engines and hybrid or plug-in technologies across four brands (Buick, Cadillac, Chevrolet and GMC) accounting for 13 separate models. This number will grow even more in 2013 thanks to cars like the all-electric Spark, the diesel Cruze, the range-extended Cadillac ELR and the Buick Encore compact CUV.
GM's small car sales were up 39 percent last year helping to attain this million-sales mark for 30-mpg models, and almost 40 percent of all GM sales consisted of cars with fuel-efficient I4 engines. In regards to more advanced means of improving fuel economy, GM says that it plans on having 500,000 vehicles with "some form of electrification" on the road by 2017.
