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.

GM applies for LT5, LTX trademarks... are new small block variants coming?

Recently discovered General Motors trademark applications for LT4, LT5, LT88 and LTX have observers wondering what kind of high-performance offerings could be on their way. A new LT4 would mark a return of the engine designation first used on the Corvette Grand Sport, SLP Pontiac Firehawk and SLP Chevrolet Camaro SS from 1996 and 1997. Supposition at Corvette Forum - which provided advance intel on the C7 like these leaked images - believes a new LT4 could go into the high-performance trim of the next-gen, 2015 Camaro that would be more powerful than the 580-horsepower Camaro ZL1.
Seeing an LT5 again would also be déjà vu - in its former life it was a 5.7-liter V8 for the C4 Corvette ZR-1 from 1990-1994 designed by Lotus, producing from 370 hp to 405 hp. A mix of rumor and hope is that the new LT5 will be a supercharged evolution of the 6.2-liter LT1 (pictured) placed in the new C7 Corvette, and that it will go into the C7 version of the ZR1 pumping out something like 700 hp.
The LTX trademark is, as with that last letter, a complete mystery. If the "X" isn't a generic way to denote the whole LT family, it's wondered if it LTX could refer to a crate motor offering like the LSX.

GM tells 2021 Chevy Express and GMC Savana owners to park vans outside due to fire risk

GM is telling owners of certain 2021 Chevrolet Express and 2021 GMC Savana work vans to park them outside and away from other vehicles and structures due to a fire risk. Additionally, the company is recalling 10,154 of the vans it believes to be at risk of catching fire. The breakout is 7,891 for Chevy and 2,223 for GMC.  Only vehicles equipped with the 6.6-liter V8 (the new-for-2021 engine option) are included in the recall, and it’s limited to vans produced on or prior to December 7, 2020. The problem stems from some anti-rotation tabs on the positive battery terminal that are too close to a fuse block assembly attachment post. This lack of clearance could cause the tabs to come into contact with the fuse block, causing a short circuit. GM points out that a short-circuit of this nature could cause battery drain or lead to a fire under the hood. Your warning for the time being will come in the form of a low battery voltage warning, or you might just wake up with an unexpected dead battery. GM says that it first opened an investigation into this problem on January 26 this year after it was notified of an underhood battery fire on a 2021 Express. The investigation found three other underhood fires and concluded that these fires were originating from the positive battery cable attachment near the fuse. This recall was officially posted on March 11 this year, and the National Highway Traffic Safety Administration just sent a notification out to the media yesterday. The fix is a relatively simple one. Dealers are going to remove a portion of the anti-rotation tab on both positive battery cable terminals near the fuse block assembly attachments. This increases the clearance and eliminates the risk of fire, GM says. The job will be done under warranty, and GM says it will begin contacting owners for recall work on May 3 this year.
