1964 Ford GT40 prototype to be auctioned in April

The Ford GT40 owns a firm spot on the list of the greatest American racecars ever made, being the first car from the United States to take an overall win in the 24 Hours of Le Mans. And now Mecum will auction what it claims is second-oldest GT40 still in existence at its Houston sale on April 12.
The story of the GT40 is fascinating. Henry Ford II attempted to buy Ferrari in the early '60s, but Enzo refused. Ford decided if he couldn't have them, then he would beat the Prancing Horse on the track. Ford went to Carroll Shelby and asked him to spearhead the program. The early cars combined a steel monocoque chassis with Ford's 4.2-liter V8 engine pumping out around 350 horsepower. The first prototype made its public debuted on April 1, 1964, at the New York Auto Show.
Shelby kept building prototypes, including GT/104, which is for sale here. This version featured a lighter steel chassis and was raced at Le Mans in 1964. However, a fire forced it to retire. It was then repainted and had a 4.7-liter (289-cubic-inch) engine fitted. The chassis had its best finish at the 1965 Daytona Continental 2,000 Kilometers where it finished third with Bob Bondurant and Ritchie Ginther behind the wheel. Later that season, it was shipped back to Ford where it was restored and displayed at auto shows until 1971 when the automaker sold it. Since then, it has had many private owners.

2015 Ford Mustang fuel economy ratings leaked

Thinking about buying a new Mustang, but want to know what kind of fuel economy it'll get? Well we have our first indication as the pony-car enthusiasts over at Mustang6G.com have gotten a hold of the Monroney window stickers for a few of the new 2015 Mustang models.
Although the V8 model is not among them, we can now see how the EPA has rated those models with a half dozen pistons or less. The Mustang EcoBoost with the turbo four and a manual transmission has been rated at 22 miles per gallon in the city and 31 on the highway. The V6 manual gets 17 city and 28 highway, while the V6 automatic squeezes out a bit more in the city at 19 mpg but carries the same 28 highway rating.
By way of comparison, the latest Chevy Camaro with the V6 and a stick shift gets the same 17/28 EPA rating as a similarly equipped new 'Stang, and the V6 automatic Camaro gets 18/27 (slightly behind the Ford, but if you opt for the Camaro 2LS with its V6, automatic and 2.92 rear axle ratio, you'll be looking at 19 and 30).

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!"
