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!"

Porsche 911 tops a list of must-have classics, but No. 2 is more of a surprise

No surprise here: In Europe, the Porsche 911 is the most sought-after classic car. Surprise here: Slip-streaming the 911 in the most sought-after chart compiled by the Car & Classic marketplace is the Ford Mustang. Using the Google search engine as a means to pick the winners, as well as the average prices achieved on the “Car and Classic” website, the venerable 911 was tagged 1.45 million times per month according to data stretching back 15 years. The number of 911Â’s sold though the C&C marketplace was 21,141, at an average price of 58,409 pounds, or $74,300. FordÂ’s pony car, still a popular choice for buyers in Europe, placed second on the list with 1.2 million monthly searches. The average sales price over 15 years was 31,107 pounds ($39,570), and the number of older Mustangs sold reached a total of 8,332. Models that also finished among the charted top 10 include the Land Rover Range Rover, the Corvette, the ultra-classic British favorite Jaguar E-Type and the BMW 3 Series. “Whilst a 1973 Porsche 911 Carrera 2.7 RS could set you back the best part of GBP500,000 ($636,000), there are many more affordable models, which bring the average sale price of a 911 on Car & Classic to GBP58,000 ($73,800) – the third highest average selling price of any make and model on the site,” explained Dale Vinten of Car & Classic. According to the site, the Jaguar fetched the highest average selling price: a whopping 89,000 pounds, or $113,000. But thatÂ’s peanuts compared to a Series 1 Roadster in excellent condition, said Vinten. For that, “you can expect to spend up to GBP250,000 ($318,000), A Series 2 or 3 will cost less, as they are not as desirable, but in decent condition you can expect to pay around GBP40,000-GBP50,000. Even a barn find 1969 E-Type Series 2 Roadster can set you back to the tune of GBP33,000 ($42,000)." Launched in 2005, Car & Classic is among EuropeÂ’s most popular classic car clearinghouses. It also runs a stand-alone auction site.

Ram 1500 bests new F-150 in MT pickup shootout

Ford's 2015 Ford F-150 is a technological tour-de-force, what with its aluminum-intensive construction and its powerful and efficient new 2.7-liter EcoBoost engine option. But now that it's hit the market, it's time to get down to brass tacks and find out how just the latest F-150 actually stands up to its rivals in the hyper-competitive fullsize segment. Motor Trend is among the first to round up the Ford (in Lariat 2.7-liter 4X4 guise here) and put it up against the Ram 1500 Outdoorsman EcoDiesel 4x4 and 5.3-liter-equipped Silverado 1500 LTZ Z71 to find out how Dearborn's new-think truck measures up. The test put the trio through over 1,000 miles of tough driving in California and Arizona in a variety of conditions from just cruising around unladen to hauling a trailer. MT found all three trucks to be competent, but the most praise got heaped on the Ram and the Ford, with the Chevrolet falling a step behind its competitors in many tests. Among the Ford's most-liked features was its 2.7-liter, twin-turbo V6 that helped make the F-150 easily the quickest of the group, with some editors saying the engine felt about the same whether driving around with cargo in the bed or not. There was some minor turbo lag during acceleration while trailering, but that issue affected the Ram, too. The Ram's powertrain was lauded, as well. The EcoDiesel was torquey around town, and the 1500's combination of an eight-speed automatic and air suspension was judged to be the best of the lot. It was the most difficult to get into the bed, though. The Ram also won the fuel economy award by netting 20-miles-per-gallon city and 28-mpg highway in the test to beat its Environmental Protection Agency ratings of 19/27. The Ford's EcoBoost managed 17/22, one mpg off each from the EPA numbers, and using a lot of throttle really depleted its efficiency. As MT notes, however, it would take time for the diesel's mileage savings to pay off at the pump for these two trucks. In the end, the Ram just barely eked out the win, with the title partially earned because of "the Ford's unknown maintenance and aluminum repair costs," according to MT.
