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!"

2016 Chevrolet Camaro design teased

Chevrolet just can't seem to help itself from continuing to tease the next-gen Camaro. The pony car gets its official debut at a big event on Detroit's Belle Isle on May 16, but the upcoming model's new exhaust, suspension components, and wheels are already well known. With this latest taste, we're finally getting an official glimpse at what the coupe actually looks like. The 2016 Camaro's shape hasn't completely been a secret, and even Chevy showed it testing while covered in camouflage in March. Still, these shots are a great opportunity to check out some undisguised details for the new model. The styling is supposed to be "more athletic," according to Chevy, and the aluminum hood looks especially good with crisp, straight lines forming the design. "It's a more expressive evolution of the Camaro's iconic character – and one that complements its leaner size and sharper reflexes," GM global design boss Ed Welburn said in a statement. These two photos suggest a more angular, futuristic shape for the upcoming pony car. We're looking forward to seeing it all in a couple weeks. Sculpted Exterior Reflects 2016 Camaro's New Athleticism 2015-04-30 DETROIT – For the all-new 2016 Chevrolet Camaro, the design team set out to create a leaner, more athletic design that complemented the new driving experience. "The Camaro went to the gym and came out with a lithe, more athletic physique for the sixth generation," said Ed Welburn, vice president, GM Global Design. "It's a more expressive evolution of the Camaro's iconic character – and one that complements its leaner size and sharper reflexes." The exterior design vocabulary is defined by complex shapes, which appear to be form-fitted around the mechanical components. Every shape and surface detail is a skilled, artistic collaboration of hand and digital sculpting. Camaro's new design details draw the eye into the design. For example, the new aluminum hood features powerful, smoothly curved sculpted forms accented with sharp creases. As a result, the hood appears to be shrink-wrapped around the engine. Similarly, the new Camaro retains the broad, dramatic rear fenders that became a defining feature of the award-winning Gen 5 Camaro. The design is updated with greater detailing, including a subtle crease running parallel to the fender edge. The effect makes the new Camaro look even lower and wider despite having a slightly smaller footprint than its predecessor.

GM will recall 3.5 million pickups and SUVs to fix brake issue

WASHINGTON — General Motors Co is recalling 3.46 million U.S. pickup trucks and SUVs to address a vacuum pump issue that could make braking more difficult and increase the risk of a crash. The recall, which covers 2014-2018 model year vehicles, including some Cadillac Escalade, Chevrolet Silverado, Chevrolet Tahoe, GMC Sierra, Chevrolet Suburban and GMC Yukon vehicles, was triggered because the amount of vacuum created by the vacuum pump may decrease over time, GM told the National Highway Traffic Safety Administration (NHTSA) in documents posted Wednesday. NHTSA opened a preliminary investigation into the issue in November 2018, and said it had reports of 9 crashes and two injuries related to the issue. It provided GM in July with additional field reports that prompted the automaker to open an investigation. The company did not immediately say on Wednesday how many injuries or crashes are linked to the issue but said it could impact braking in "rare circumstances." GM said dealers will reprogram the Electronic Brake Control Module with a new calibration that will improve how the system utilizes the hydraulic brake boost assist function when vacuum assist is depleted. GM said the vacuum assist pump, which is lubricated with engine oil that flows into the pump through a filter screen, can in some cases lose effectiveness over time, as debris such as oil sludge can accumulate on the filter screen. GM told NHTSA that prior model years used a different brake assist system design, and vehicles manufactured after 2018 were not equipped with the affected pump design. Recalls Chevrolet GM GMC
