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!"

MotorWeek remembers a better time for Mitsubishi performance

Dodge still knows how to create an capable performance car – look at the Hellcats, for example – but the same isn't true for Mitsubishi. With the Lancer Evo's demise, we don't expect driving enthusiasts to clamor for any of the Japanese automaker's other products. Things used to be different, though. As MotorWeek found in its new Retro Review, the 1991 Mitsubishi 3000GT VR4 and its sibling, the Dodge Stealth R/T Turbo, were impressive sports coupes in their day. Dodge and Mitsubishi packed a bevy of cutting-edge tech into the coupes. In these trims, both sported all-wheel drive, four-wheel steering, an adjustable suspension, active exhaust, and automatic climate control. The 3000GT VR4 upped the ante even more with active aero parts at the front and rear. Their 3.0-liter twin-turbo V6 was good for 300 horsepower and 307 pound-feet, which were good numbers at the time. This pair put all their gizmos to good use, too. MotorWeek compares the all-wheel-drive system's grip levels to a Porsche 911 Carrera 4. When was the last time you heard any favorable similarity between a Mitsubishi and a Porsche? The Stealth R/T Turbo and 3000GT VR4 came from a special time for Japanese sports coupes, when every brand had a halo model. Whether you were looking at Nissan 300ZX, Mazda RX-7, Toyota Supra, or even the Acura NSX, there was a lot to like on the market. MotorWeek's latest Retro Review offers a great reminder of that period.

Chrysler banks $507 million in Q2, trims 2013 earnings forecast

Chrysler has some good news and some bad news. First, profits were up 16 percent over the second quarter of 2012, bringing the Auburn Hills, Michigan-based manufacturer $507 million on the back of strong demand for trucks and SUVs (a recurring theme this quarter, particularly in the US). Q2 revenue was up as well, from $16.8 billion in 2012 to $18 billion in 2013. The bad news is that the Pentastar's overall earnings forecast for net income in 2013 has been trimmed from $2.2 billion to between $1.7 and $2.2 billion, according to Automotive News.
In addition to the adjusted net income forecast, Chrysler tweaked its operating profit from $3.8 billion to between $3.3 and $3.8 billion. This has gone largely unexplained by Chrysler, perhaps hoping the news of a three-percent increase in its transaction prices for Q2 will allow it to sweep this adjustment under the rug.
The star of the show for Chrysler has been its US sales, which saw a 10-percent jump, both bettering the industry average of eight percent and improving over the same stretch of 2012. As with the increase in transaction prices, Chrysler has the new Ram pickup and Jeep Grand Cherokee to thank. Perhaps most worrying from this report, though, is that every brand in the automaker's stable saw an increase in sales... except for the Chrysler brand itself.
