Final C6 Corvette built in Bowling Green

With all of the attention given to the 2014 Chevrolet Corvette Stingray lately, you could be forgiven for thinking that it's already well along in production, yet tooling up for the new C7 has only just begun. In fact, production of the outgoing C6 generation in Bowling Green, Kentucky just halted on Thursday.
As the C6 has aged, production numbers have predictably ebbed along with demand, but this year, the addition of the 427 and 60th anniversary models resulted in an uptick in vehicles built - this, despite a model year shortened by around 25 percent to accomodate the new model changeover. The final C6 Corvette ever, No. 13,466 built this year, was a white 427 Convertible destined for the General Motors Heritage Center museum. The car's 7.0-liter V8 heart was assembled by Corvette chief engineer Tadge Juechter himself.
In total, Bowling Green pushed out 215,100 C6 Corvettes over nine years. If you're still a C6 fan at heart and are hoping to get a good deal on a phase-out model, step lively - Chevrolet reportedly had about 6,100 unsold units, which Autoweek suggests is good for around five and a half months of supply at the model's current sales rates. Given that demand will likely slacken even further as the C7 draws closer, that should be a big enough stockpile to keep dealers satisfied until 2014 Stingrays begin showing up on their forecourts in December.

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!"

How Chevy Silverado, GMC Sierra will take on the Ford F-150 profit machine

FORT WAYNE, Ind. — When General Motors engineers were developing the 2019 Chevrolet Silverado and GMC Sierra pickup trucks, some of them joined public tours of Ford's Dearborn, Mich., factory to watch aluminum-bodied F-Series trucks go down the assembly line. The redesign of the Ford F-Series trucks, launched in 2014, set a new standard for fuel economy and lightweight vehicle construction. But armed with stopwatches and trained eyes, the GM engineers believed they saw problems. "They had a real hard time getting those doors to fit," Tim Herrick, the executive chief engineer for GM truck programs, told Reuters. His team did more intelligence gathering. They bought and tore apart Ford F-Series doors sold as repair parts. Their conclusion: GM could cut weight in its trucks for a lower cost using doors made of a combination of aluminum and high-strength steel that could be thinner than standard steel, shaving off kilograms in the process. These pounds-and-pennies decisions will have major implications in the highest-stakes game going in Detroit: dominance in the world's most profitable vehicle market, the gasoline-fueled large pickup segment. What's more, GM is banking on strong sales of overhauled 2019 Silverados and GMC Sierras to fund its push into automated and electric vehicles — a business many investors see as the auto industry's long-term future. The risks are high given the hits automakers have taken from U.S. President Donald Trump's trade policies. Rising aluminum prices spurred by Trump's tariffs are driving up costs on the Ford's F-Series, while rising steel and aluminum prices likewise drag on GM results. GM also has a significant risk should the United States, Mexico and Canada fail to agree on a new NAFTA trade deal, given GM trucks built at its Silao, Mexico, factory could face a 25 percent tariff if NAFTA collapses. Major profit per truck Interviews with GM executives and a tour at its factory here in northwest Indiana provide a detailed look inside GM's plan for the most important vehicles in its global lineup. These big pickups are everything Tesla's Model 3 or Chevy's Bolt electric car is not. The mostly steel body is bolted to the truck's steel frame, rather than the one-piece body and frame electric vehicles. The majority of trucks will have a V-8 gasoline engine powering the rear wheels — like the classic GM cars of the 1950s. Some Silverados will have new four-cylinder engines, but there is no electric or hybrid offering as of now.
