AMC Trans Am Javelin SST, an ultra-rare underdog, is up for auction

Among the rarest of the American muscle cars that went racing in the early Seventies — cars including the Camaro Z/28 and the Boss 302 Mustang — the 1970 AMC Trans Am Javelin SST may be the most hard to find, and among the most valuable. Only 100 units of this unique Javelin were produced, and one of them is up for auction at the Mecum event in Dallas on September 20. The Trans Am Javelin was fashioned in a patriotic livery of tricolor paint — red, white and blue — and arrived after the American Motors Corporation had decided in 1968 to compete in the Trans Am racing series against Ford and General Motors. The company's chief driver, Mark Donohue, would dominate the 1971 season, taking seven wins in his Javelin AMX and that yearÂ’s SCCA Trans-Am Championship. AMC took the trophy with 82 points, well ahead of Ford's 61, Chevrolet's 17 and Pontiac's paltry 7. The example listed for auction came equipped with a 390-cubic-inch V-8 engine with 325 horsepower at 5,000 rpm and 420 pound-feet of torque, power steering and brakes, dual exhaust, BorgWarner four-speed manual transmission and Hurst competition shifter. Its “ram induction system” sealed a chamber around the air filter so that cool air from the functional hood scoop would be funneled into the intake. This JavÂ’s factory price was $3,995 — a mere $32,000 or so in today's money, though it was expensive by the standards of the time. The 100 Trans Ams were among 19,714 Javelin units built in 1970, so they started out rare, and today the surviving examples are highly collectible, if and when they come up for sale.

2014 Chevrolet Impala [w/video]

Can A Fleet Queen Become a Fullsize King?
On paper, the Chevrolet Impala is a pretty strong seller, posting annual sales that have hovered right around 170,000 units for the last two years, but it only takes one trip to practically any rental car agency to discover where the majority of those sales have come from. In fact, General Motors told Autoblog that a full 70 percent of Impala sales last year went to fleet companies for things like rental cars and government vehicles. Logic tells us that this is neither good for resale values nor name equity, so Chevrolet is getting ready to roll out an all-new Impala with improved comfort, styling and technology, hoping to turn the tables on its retail-to-fleet ratio.
Chevrolet's sedans have come on quite strong in the last few months with the introduction of the Cruze diesel and the SS sedan, but while these will likely be low-volume sellers, there's more pressure for the new Impala to perform well as GM looks to slash fleet sales and compete with the wide variety of full-size sub-luxury sedans. Riding on a platform shared with the Buick LaCrosse and Cadillac XTS, the 2014 Impala will compete against the Hyundai Azera, Ford Taurus and Toyota Avalon on the more traditional side, while also looking to take a bite out of somewhat sportier models like the Chrysler 300/Dodge Charger twins and the Nissan Maxima. We headed to sunny San Diego to see if this totally new Impala can stand on its own without the assistance of fleet companies and rental agencies. [w/video

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!"
