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!"

Historic race cars highlight the RM Sotheby's 2023 Le Mans sale

Auction house RM Sotheby's is celebrating 100 years of the 24 Hours of Le Mans by organizing a big sale on the day before the race. The cars scheduled to cross the auction block have all spent time on the track, and the catalog shows how racers have evolved since the 1930s. Browsing through RM's auction catalog is like taking a five-minute course in the history of racing. The oldest car is a 1932 Aston Martin Le Mans 'LM8' that's had a remarkable life. It was developed and built for competition and entered in the 1932 24 Hours of Le Mans by the Aston Martin factory team, where it finished seventh. It was ultimately sold to a private owner but it survived, which shouldn't be taken for granted: teams often destroyed obsolete race cars, and the list of special vehicles that didn't survive World War II is longer than you'd think. Paul Sykes bought the car in 1955 and used it as his daily driver. Imagine walking out of a shop in a British village in the 1960s and finding a 1932 race car parked next to your Mini. Sykes ultimately bought another daily driver, but he kept the Aston Martin for a total of 55 years. The second-oldest car is a 1936 Delahaye 135 S with a body by coach builder Pourtout. RM notes that this is one of the most significant pre-war competition Delahaye models and adds that it finished second in the 1938 edition of the 24 Hours of Le Mans. It continued racing until 1956 and then spent several decades hidden in storage. It was fully restored in 2005, and it's now eligible to compete in historic races such as the Mille Miglia and the Le Mans Classic. Restoring it was easier said than done: the car was rebodied twice before being tucked away. None of the cars crossing the block were built in the 1940s, so we skip ahead to the 1950s with a 1954 OSCA MT4 by Morelli. It's one of 72 built, according to RM, and only 19 of those were fitted with the twin-cam, 1.5-liter 2AD engine. It raced at Le Mans in 1954 but ended up disqualified following an accident. Another highlight from the 1950s is a 1958 Lister-Jaguar 'Knobbly' finished in yellow and green. We said that all of the cars crossing the block have spent time on the track, but that doesn't mean they were built to race. The 1963 Ferrari 250 GTE 2+2 Series III is a street-legal model, yet it's included in the auction because it was used as a safety car during the 1963 edition of the race.

Say goodbye to the Dodge Dart and Chrysler 200

Fiat-Chrysler CEO Sergio Marchionne outlined an update to the company's five-year business plan Wednesday, and among the changes, the Dodge Dart and Chrysler 200 sedans will soon be phased out. The company's presentation to investors states that the "market shift from cars to trucks and UVs [utility vehicles is] now seen as permanent shift in demand," and FCA wants to respond as quickly as possible. Killing the 200 and Dart will allow FCA to build more Jeep and Ram models at the Sterling Heights, MI, and Belvidere, IL, plants where the sedans were produced. We already knew FCA was planning to shift 200 and Dart production to Mexico, to free up the Sterling Heights facility for Ram 1500 production, and the Belivdere site for Jeep Cherokee output. The Cherokee will move from its current home in Toledo, OH, to allow for increased Wrangler production. It's no shock that FCA wants to shift its focus to crossovers and trucks. In December 2015, for example, combined sales of the Dodge Dart and Chrysler 200 were 15,310. The Jeep Cherokee, which uses the same platform as the Dart and 200, outsold both models combined, with 24,049 sales. Both the Dart and 200 had troubles from the beginning. Marchionne recently blamed designers for the 200 not receiving a Consumer Reports 'recommended' rating, and the Dart was one of the lowest-scoring cars in a CR reliability study.
