GM Design shows what could have been and what might be

We periodically like to check in with GM Design's Instagram account to see what they're cooking up. Even better is when we catch a glimpse of an alternate history of what legendary designers from The General's past were thinking, though those ideas may not have made it into production. This week, for example, the account posted some illustrations from George Camp, whose career at GM spanned nearly four decades, from 1963 to 2001. One of the renderings is of what appears to be a 1971-72 Pontiac GTO Judge, but with two headlights instead of the production unit's quad beams. The rear departs from the canonical version most dramatically, with a massive integrated wing. Other bits that didn't make the production cut include large side vents, a gill-like side marker and rectangular intakes below the headlights that wouldn't be out of place on a modern design today. Amazingly, from what we can make out of the date, it appears that the drawing was done sometime in 1965, which makes it quite prescient.           View this post on Instagram                       A post shared by GM Design (@generalmotorsdesign) There's also a very aerodynamic interpretation of a Corvette ZR-1. To our eyes it splits the difference between the 1986 Corvette Indy concept and a fourth-generation F-body Pontiac Firebird, so perhaps parts of Camp's work on this sketch did make it into physical form. There's also a radical sports car concept from May 1970 that resembles the Mazda RX-500 concept from the same year, a Syd Mead-looking Cadillac coupe, and an Oldsmobile with a cool take on the company's trademark waterfall grille and elements of the Colonnade Cutlass at the rear. Other recent posts include a FJ Cruiser-like off-road EV, a sleek coupe with the Chevy corporate grille, and a rendering of a Silverado-esque pickup that looks far better than the current production version.           View this post on Instagram                       A post shared by GM Design (@generalmotorsdesign) It's pretty easy to lose hours in the account, but it's always fascinating to see GM's visions of what could have been and what might be.

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.

Chevy Sail 3 lands in China

Shanghai General Motors took 32 cars to this year's Guangzhou Motor Show, with its Chevrolet Sail 3 leading the way. After putting almost 1.4 million of them into Chinese hands, the third generation of the Bowtie's entry-level sedan wants to "take the nameplate and the segment to a new level." Its new architecture sporting a 1.4-inch longer wheelbase supports a growth spurt of two inches in length and 1.8 inches in width. The exterior also gets "eagle eye-shaped" headlights and "dual-c-element taillights." Under the hood will be either a 1.5-liter DVVT or a 1.3-liter VVT, each of them more powerful and more frugal than previous offerings. Both can be paired with a manual or an automatic transmission, and qualify for listing in China's National Energy-Saving and Eco-Friendly Vehicle Catalogue, as well as a 3,000 renminbi rebate ($490 US). You can read more about it in the press release below, and get more info on the Chevrolet Camaro RS Limited Edition, Corvette Stingray Coupe, Buick Regal GS and Excelle XT also introduced at the show.

Built on Shanghai GM's new-generation small car architecture, the Sail 3 has adopted Chevrolet's new design language. It has a sculpted yet slim exterior with a youthful, dynamic feel.
