Only in Japan: Dodge van one-make racing series is a thing

Japan seems willing to embrace a level of automotive insanity that many other places lack. Whether it's 1,200-horsepower Nissan GT-Rs blasting through tight, tree-lined mountain roads or advertisements with dances for the Toyota Prius Plug-in, the country definitely has a unique way of expressing a love for autos. The D-Van Grand Prix might be one of our favorite examples yet of crazy Japanese car culture, because the annual, one-make race at the Ebisu Circuit is exclusively for heavily customized Dodge vans. Like many great things, this wonderfully crazy idea came from a little rule breaking. D-Van Grand Prix organizer Takuro Abe was at a track event for a motorcycle racing school, and vans were used to haul the bikes around. During lunch someone came up with the idea for a race. Ignoring that the big machines weren't actually allowed on the circuit, the drivers headed out. The popularity has just grown since then. These days, the racing vans absolutely aren't the stock machines from the event's inspiration. In addition to stripped interiors and track rubber that you might expect, the list of mods for them is a mile long. For every possible advantage, the racers fit them with things like Brembo brakes, cross-drilled rotors, heavy-duty transmissions, and much more. Seeing vans lumbering around the track is very weird at first, but the racers take the competition very seriously. These folks even employ all sorts of little tricks to coax the most from the machines. This is a fascinating motorsports story, but be sure to turn on the subtitles to understand the interviews with the competitors.

Mopar maneuvers into SEMA with a multitude of modified models

As the aftermarket and performance arm of Fiat Chrysler Automobiles, Mopar has a duty to extract everything from the company's models that it can, and there's no better place to show all of its work off than the annual SEMA Show.
Dodge really gets in on the act this year with several customs to show off different parts of the brand's performance heritage. Perhaps the most interesting among them is the track-prepped Viper ACR Concept (pictured above). It wears a custom body kit to produce even more downforce, thanks in no small part to a monstrous wing at the back. To shed weight, most of the interior is stripped out, as well. Next up, the Challenger T/A Concept takes inspiration from '70s Trans-Am racing in a livery of Sublime Green and matte black paint. The center scoop in the hood keeps the 6.4-liter V8 fed with cool air, and the special's 20-by-9.5-inch matte black wheels keep it planted in the corners.
Also getting the once-over from Mopar is the Charger R/T. It wears the division's body kit, and under the hood, a cold-air intake keeps the 5.7-liter V8 breathing. The suspension is retooled to hold the road better with a coil-over kit, upgraded sway bars and strut tower braces for the front and rear. The company is also showing off a snazzy blue Charger with a mean look. The final Dodge getting work from Mopar is the Dart R/T Concept with bright, O-So-Orange paint and a matte black hood with a scoop hooked directly to the air intake. The performance-oriented design is finished off with a coil-over suspension and big brake kit, as well.

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!"
