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!"

Rare Dodge Daytona found in barn heads for auction

An American icon is headed to Mecum's Kissimmee, Florida auction next January. Charlie Lyons, owner of a restoration shop focused on old Chrysler products, got a lead on a two-owner 1969 Dodge Charger Daytona that had been sitting in a barn in Glenwood, Alabama for decades. Dodge built 560 Charger Daytonas (Canada and US production) to homologate the model for NASCAR racing, and then that car and the successor Plymouth Superbird terrorized NASCAR tracks for 18 months. The production car, however, 18 feet long and considered ugly, wasn't popular at the time, so many were beat up or simply disappeared. Around 385 are thought to exist today. Lyons said the first owner of this car was the town judge, who bought it for his wife. In 1974 the second owner - just 18 years old at the time - bought it for $1,800 so he could drive it to Panama City, Florida, for Spring Break, and had flames painted on the front fenders and the scallops trimmed in white. Otherwise this barn find is complete and stock, with matching numbers throughout, R4 Charger Red paint and a white tail, bucket seats, center console, three-speed TorqueFlite automatic, and 20,553 miles on the 440-cubic-inch Magnum V8. Hot Rod has the long story of how Lyons found the car and convinced the owner to sell for what he jokingly called "a shoebox full of folded money." Hagerty says a concours-worthy model can command $262,000. Mecum's pre-sale estimate for this Charger Daytona is $150,000 to $180,000. That sounds steep, but Mecum did sell another perfectly restored Hemi-powered 1969 Charger Daytona for $900,000 at this year's Kissimmee auction to actor David Spade. Related Video:

Chrysler expecting up to 200,000 9-speed transmissions for 3 models this year

Striving for improved fuel economy, we already knew that Chrysler will begin using a nine-speed automatic transmission in some of its new products this year, but what we haven't known is that volume at which this gearbox will be used. According to Bloomberg, Chrysler CEO Sergio Marchionne has been quoted as saying that the automaker expects to sell close to 200,000 units equipped with this new transmission in 2013. Those gear-rich trannies will be spread out across three models, consisting of the redesigned Chrysler 200, the still-unnamed Jeep Liberty replacement and the Dodge Dart.
This transmission should play a pivotal role in making Chrysler vehicles more competitive in their respective segments. Just for comparison, one of the Dart's key competitors, the Toyota Corolla, still uses a four-speed automatic, and a previous report indicates that the next-generation 200 could get up to 38 miles per gallon on the highway, which is better than most non-hybrid midsize sedans on the market. Marchionne says that the new Jeep model is expected during the second quarter of this year, but there is no word as to when the new 200 or nine-speed Dart will debut, but clearly Dodge would like to have the transmission in its compact yesterday. As for that volume figure, it definitely doesn't seem out of reach since the Dart, Liberty and 200 combined for a total of more than 225,000 units in 2012.
How many more gears can we expect in future cars? Probably not many more, since the CEO of transmission-builder ZF, Stefan Sommer, previously stated that nine speeds was the "natural limit" for transmissions.
