GM files for Z71 Trail Boss trademark

Try as they might to keep their plans a secret, automakers have their hands tipped through a variety of methods – be they through loose lips, spy shots or patent and trademark applications. That's how we know, in this instance, that General Motors is working on (or at least considering) an off-road machine wearing the name Z71 Trail Boss – the name which our compatriots at AutoGuide.com tell us that GM has registered for use on light-duty trucks. Now if that alphanumeric designator sounds familiar, it should. GM has long used it to designate the off-road packages on many of its body-on-frame trucks from Chevy and GMC. These days you can order a Z71 package on the Chevy Colorado, Silverado, Tahoe and Suburban and on the GMC Canyon, Sierra and Yukon. The package typically includes components like a beefed-up suspension bits, high-capacity air cleaner and underbody protection plates. The Trail Boss designator would seem to suggest something further reaching than a suspension package, though. Just what it would entail we don't know; minds immediately start running toward Chevy or GMC going after the Ford F-150 Raptor, but we'll likely be looking at something closer to the Trailhawk packages Jeep offers on the likes of the Renegade and Cherokee.

Why does the Corvette Stingray have so many vents? Here's why

Just looking at the new 2014 Chevrolet Corvette Stingray, it's not hard to see that the car's design was created with aerodynamics at the forefront, but Chevrolet designers point out exactly what went into designing the iconic coupe in a pair of recently released videos. The videos show the Corvette going through early design phases, including clay models and wind tunnel tests, as well as talking to the car's chief engineer, Tadge Juechter.
Both videos help explain various aspects of the C7 Corvette, but it's the aero tuning of the car that is most interesting. This includes extra attention paid to the lower air dam and vented hood to help reduce drag and lift, while the rear quarter inlets are for differential and transmission cooling. Juechter said that some of these aero-tuned elements were inspired from GM's involvement in racing.
If you have about five minutes and you can't get enough information about the new 'Vette, then check out the videos posted below.

Chevrolet To Oversee Restoring Sinkhole Corvettes

What Mother Earth devoured, Chevrolet plans to resurrect. The carmaker said Thursday it will oversee restoration of the classic cars swallowed by a huge sinkhole beneath the National Corvette Museum in Kentucky. General Motors Design in Warren, Mich., will manage the painstaking work to repair the eight prize vehicles, the automaker said Thursday. The cars were consumed when the earth opened up early Wednesday beneath a display area when the museum in Bowling Green, Ky., was closed. No injuries were reported. The museum was open Thursday except for the area where the sinkhole occurred. Mark Reuss, GM's head of global product development, said the damaged vehicles rank as "some of the most significant in automotive history." "There can only be one 1-millionth Corvette ever built," he said, referring to one of the damaged cars. "We want to ensure as many of the damaged cars are restored as possible so fans from around the world can enjoy them." Just how the cars will be pulled out of the ground remains to be seen, said museum executive director Wendell Strode. The local fire department estimated the hole is about 40 feet across and 25 to 30 feet deep. The hole opened beneath part of the museum's domed section. "We feel pretty confident that most of the cars can be extracted," Strode said Thursday. "And we hope and believe that with just a little bit of luck, that all eight cars can be extracted and be part of the restoration." Chevrolet spokesman Monte Doran said some of the cars look to be in good shape, while others are buried in rubble. "It will likely be several weeks until we can get the cars out and assessed," he said. The GM Design team has helped restore other historic cars, but the Corvette project looks to be its biggest, he said. "These Corvettes are part of our history, and they want them restored properly," Strode said. "We're thrilled they're doing this." The cars looked like toys as they plunged into the hole, piled in a heap amid dirt and concrete fragments. The museum owns six of the cars while two - a 1993 ZR-1 Spyder and a 2009 ZR1 Blue Devil - are on loan from General Motors. The other cars damaged were a 1962 black Corvette, a 1984 PPG Pace Car, a 1992 White 1 Millionth Corvette, a 1993 Ruby Red 40th Anniversary Corvette, a 2001 Mallett Hammer Z06 Corvette and a 2009 white 1.5 Millionth Corvette. Pictures of the sinkhole showed a collapsed section of floor with multiple cars visible inside the hole.
