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!"

Here's the 2016 Chevy Camaro Convertible

Chevrolet is planning to reveal the 2016 Camaro Convertible on Wednesday, June 24. But here it is ahead of time, thanks to some leaked images found by the folks at Camaro6.com. These photos were apparently posted to Chevy's website and then immediately taken down. But they clearly show the new droptop Camaro from a number of angles, with the top both up and down. Not surprisingly, the Camaro's design hasn't changed for the convertible body style, and it looks pretty good. Have a look at the low-res images in the gallery above. We'll have the full details later this week.

2016 Chevy Silverado unveiled in full at Texas State Fair

It's State Fair time down in the Lonestar State, which means a lot of things to a lot of Texans: rodeos, cook-offs, country music concerts, big belt buckles, and even bigger hats. But it also means new trucks. Ford used the occasion this year to roll out its new F-Series Super Duty pickups, but the Blue Oval won't have the show all to itself as Chevy is also on hand to reveal in full its latest updates to the Silverado. The Bowtie brand gave us our first glimpse at its updated 1500-series pickup back in July, but has now revealed the revised truck in full – and not just in Z71 spec, either. Buyers will be able to choose between WT, LS, LT, LTZ, and High Country trim levels – to say nothing of the various cab, box, and powertrain configurations. The top three get all-LED exterior lighting. And while the Z71 adopts the color-keyed trim we saw previously, other models like the LT, LTZ, and (to a lesser extent) the top-of-the-line High Country still bring the chrome for those who want it. Whichever the model, the new Silverado boasts a more muscular-looking front-end and a more sculpted hood. Inside, the new Silverado gets an optional MyLink system with Apple CarPlay and Android Auto support. The revised truck also benefits from added safety technology and convenience features. Engine options include a 4.3-liter V6 with 285 horsepower and 305 pound-feet of torque, a 5.3-liter V8 with 355 hp and 383 lb-ft, and a 6.2-liter V8 with 420 hp and 460 lb-ft. The news when it comes to powertrains is that the eight-speed automatic launched last year on the larger V8 is now being offered on the smaller 5.3 as well. 2016 Silverado: The New Face of Strong 2016 Silverado designed to build on Chevrolet's truck momentum 2015-09-24 - Bolder, more muscular look reflects Silverado strength, dependability - Expanded use of 8-speed transmissions; additional safety technologies - Available support for Apple CarPlay and Android Auto DALLAS – The new 2016 Chevrolet Silverado 1500 brings muscular designs and new customer-focused technologies to the most dependable, longest-lasting family of full-size pickups on the road. The new Silverados make their public debut today at the State Fair of Texas in Dallas. "The new 2016 Silverado will build on the Chevy truck legacy of dependability," said Sandor Piszar, marketing director for Chevrolet trucks.
