Why the 2015 Detroit Auto Show will be the best since The Crisis

The Detroit Auto Show clearly has its swagger back, and the 2015 edition will be a veritable feast for the enthusiast senses. We're talking serious performance, and it will be exhibited in a variety of forms. Sports cars. Supercars. Muscle-bound luxury cars. They're all set for splashy debuts in January in the Motor City. It's another signpost that companies have recovered from the global economic crisis that gripped the industry from 2008-09. For a while, automakers played it safe at Detroit and other shows. Environmentally friendly cars were important, especially for General Motors and Chrysler that were living on loans from Uncle Sam. Ford, Toyota and other companies generally focused on their best-selling or core models. With a few notable exceptions, recent auto shows have been a bit more buttoned-down than in the past. Boring probably isn't the right word, but austerity has been reality. That's changing. Car companies are making money. Sales are up. Aside from the many nagging recalls – and they are notable – the industry now has the time and energy to make performance cars a priority. That will be offered in hard evidence in Detroit. A year from now when we look back at this auto show, we'll sum it up with one word: Horsepower. But make no mistake, this isn't frivolous. Sports and luxury cars are expensive. They're profitable. They boost images and highlight strengths. With that in mind, here are five significant performance-oriented reveals to watch for when the show kicks off in less than two weeks. 2016 Acura NSX Acura's reborn NSX is a strong bet to earn plenty of votes for our Editors' Choice awards. It's one of the most anticipated – and strung-out – reveals of the year. Think back: we actually saw an NSX concept at the 2012 Detroit show, and Acura has spent the last three years teasing the car in a variety of ways. The slow burn, however, means we know a lot about the NSX. It's will use a mid-mounted twin-turbo hybrid powertrain and run with all-wheel drive. It will also wear an innovative zirconium e-coat paint, a new paint process that Honda says is more environmentally friendly. Honda has also said it will build the new NSX in Ohio, where a large part of the car's development work has been done. The original NSX was produced from 1990-2005 and helped establish Acura's performance credentials in the United States. It was a landmark car and a shot across the bow of Ferrari, Lamborghini and others.

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!"

The 24 Hour War: Adam Carolla's new documentary brings the Ford-Ferrari battle back to life

Long before the GoPro or even videotape, races were filmed by guys standing next to the track with 16-millimeter cameras. The images kind of shook, they didn't always hold focus, and over the years all the color has faded out of the film. It all conspires to make the endurance racing battle between Ferrari and Ford in the 1960s seem like ancient history. What Adam Carolla and Nate Adams' new documentary The 24 Hour War does best is make that inter-corporate battle feel as if it happened yesterday. Yeah, if you're an obsessive you've likely seen most of the shaky-cam race footage used here before. But what you haven't seen are the interviews that frame the war and explain the egos and engineering behind the legends. It's not a perfect movie, but it's the sort of movie only fanatics could make. And it's easier to appreciate if you're a fanatic too. The first 25-or-so minutes of the documentary are taken up with histories of both Ford and Ferrari and an overview of how ridiculously deadly motorsports were in the Sixties and earlier. It's all interesting (if familiar) stuff, that could have been handled in about a third the time with some brutal editing. Still, the two protagonists in the story are well drawn: the racing-crazed Enzo Ferrari, who only builds road cars to stay solvent; and Henry Ford II, who after being thrown into the deep end of the Ford Motor Company management in 1943 at the age of 25, wasn't going to be humiliated after Ferrari pulled out of a deal to sell him the sports car maker. With one notable exception, the filmmakers were successful in rounding up practically everyone involved who is still alive for an interview. That includes Dan Gurney, Mario Andretti, Pete Brock, Bob Bondurant, Piero Ferrari, Mauro Forghieri, Carlo Tazzioli, and even Ralph Nader. There are good archival insights from the late Carroll Shelby. But where's A.J. Foyt? After all, he co-drove the stupendous Ford GT40 Mark IV with Dan Gurney to victory at Le Mans in 1967. The interviews make the movie worthwhile, but it cries out for more technical depth about the cars themselves. Yes, the GT40 was complex and engineered practically like a production car, but there's no mention of how the Lola Mk VI and Eric Broadley kicked off the development. There's only a superficial explanation of what made the American-built Mark IV such a leap forward.
