C7 Corvette makes inaugural ad appearance in Chevy's first spot with new slogan

Chevrolet's "Runs Deep" tagline has finally been run into the ground, replaced with the Bowtie brand's "Find New Roads" slogan that's part of parent General Motors' plan to unify its everyday brand's marketing efforts worldwide. The new Chevrolet campaign was ushered in on prime time last night during the Grammy Awards on CBS, and the first spot, a 90-second full-line ad, also marks the first appearance of the 2014 Corvette Stingray in a commercial.
Being a full-line ad, the commercial is composed of vignettes centered on different vehicles in the brand's lineup. The all-new 2014 Impala also makes its first commercial appearance in dapper fashion, and time is spent on a skateboarding Sonic and a bouquet of brightly colored Spark hatchbacks driven by fashionable women. The ad starts and ends with Chevy's green halo car, the Volt, along with a young girl with her robotic dog (yes, really).
Chevrolet's "Runs Deep" campaign got off to a rocky start in the fall of 2010, but it did last for a couple of years with some tweaks. This new one, "Find New Roads" seems more intent on drawing new customers into the fold than the outgoing tagline, which seemed to play more toward the brand faithful. It admittedly reminds us more than a little the short-lived "Find Your Own Road" Saab motto (which, we note, was conceived while the Swedish brand was under GM's control), but no matter, we still think it's got more long-term potential than "Runs Deep."

GM patent reveals new two-stage turbocharger

Modern turbochargers may be some of the best ever made, but performance is something that engineers are always trying to improve. According to GM Inside News, General Motors (GM) is hoping to alleviate some of the negative aspects of a two-stage turbocharger setup with a newly-patented design. The patent, that was filed on May 19, 2016, reveals a clever bypass system that allows the engine, a four-cylinder unit, to optimize both the low-pressure and high-pressure inlets for its respective functions. According to the filing, a conventional two-stage turbocharger setup is engineered to allow both turbines to operate simultaneously at low and mid engine speeds. At high engine speeds, only the low-pressure turbine works. The setup can't isolate either the low or high pressure side, which can impair low-end performance. GM's new two-stage turbocharger setup looks to eliminate this by linking the high-pressure turbo to the exhaust manifold through the high-pressure inlet duct. The low-pressure turbo is attached to the high-pressure turbo by a low-pressure inlet duct, which is linked to a connecting channel. A single actuator that is housed in the exhaust manifold creates a bypass that can opens the high-pressure inlet or close the connecting channel. Depending on what the engine load and speed is, the ECU guides the actuator—a single rotating spindle with discs corresponding to flanges on the high and low pressure sides—to isolate one of the two turbos. Isolating the turbos allow the respective inlets to be engineered for the best possible fluid dynamic performance. The setup should increase performance and decrease lag. There's no word on what car this setup will make an appearance on, but it will most likely be used in premium vehicles before trickling down to the rest of GM's vehicles.

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!"
