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.

The real costs of keeping a Chevy Volt on the road

The release of the new, 2016 Chevy Volt is sure to bring a surge of used electric vehicles to the market as early adopters trade their older models in. Many of these cars are selling for a fraction of their original price, thanks in part to federal and state incentives that lowered the initial cost to the first owner, which opens these cars up to a whole new class of consumers. While the prices are getting attractive, potential buyers are still hesitant to buy a used EV due to uncertainty about service and repair costs, but there may be some good news on the horizon. The Chevy Volt comes with a battery warranty that is good for at least 8 years and 100,000 miles, but many of the Volts popping up on the market have passed that 100,000-mile mark. The threat of needing a new battery can be a deterrent, especially with some dealers quoting prices as high as $34,000 for a full "drive motor battery replacement." That sum is more than the MSRP of a 2016 model. Some of the fear of EV maintenance and repair comes from the mystery of the individual pieces that make up the drivetrain and charging system. If we take a look at the Volt in terms of analogs to a traditional internal-combustion vehicle, the outlook becomes a little more friendly. The Volt battery pack consists of three lithium-ion modules in a T-shaped arrangement, each of which can be serviced individually. Module 1 is made up of 90 cells and corresponds to GM part number 22954462, which retails for $3,258.33; module 2 is made up of 72 cells and corresponds to GM part number 22954463, which retails for $2,930.00; lastly, module 3 is made up of 125 cells and corresponds to GM part number 22954464, and retails for $4,933.33. These part numbers have been added to the dealer order systems but have not shown up in the distribution centers at this time. Although all three of the modules add up to a fairly large $11,121.66 total and are still on hold for dealer ordering, the good news is that in most cases these battery cell modules do not need to be replaced. There are many other individual pieces mounted on the battery pack that are serviceable, such as the Battery Energy Control Modules (BECM) and the Battery Interface Control Modules (BICM). These modules control and monitor the battery packs and charging system and have been known to fail while the lithium-ion battery cells are not at fault. Some have been replaced under warranty, but if you are stuck buying one they run about $255 a piece for the part.

First 2015 Chevy Corvette Z06 engine blows up at just 891 miles

You've waited and watched and waited some more for the arrival of your 650-horsepower, $78,000 Chevrolet Corvette Z06. Finally, that joyous day arrives and you eagerly, but gingerly, begin to break-in the 6.2-liter supercharged V8 monster under your hood. Then 900-odd miles after delivery, your excitement grinds, quite literally, to a halt. That's what the owner of one 2015 Z06 claimed happened to him when a simple break-in drive resulted in a lunched engine. The owner, known as Lawdogg149 on Corvette Forum, says he was out breaking-in his car ahead of a January track event when it happened. "While making a pull from 35 miles per hour, I accelerated and shifted short of redline, and boom - the car began knocking. I pulled over and popped the hood. I could hear a loud knock coming from the No. 6 cylinder area along with a serious, grinding, metal-on-metal sound coming from the supercharger area," Lawdogg wrote. A subsequent trip to the dealer confirmed his concerns, with the service facility telling Lawdogg that the No. 6 valvetrain had failed. The dealer couldn't research the issue further, though, as General Motors requested the engine be returned for a more thorough evaluation. The good news for the Z06's unlucky owner, at least, is that GM will be covering the engine replacement under warranty, an expense that Corvette Forum estimates is a nearly $24,000 procedure. At this point, the two leading theories behind the engine's detonation involve a manufacturing defect – which could be why GM is so keen to tear the blown powerplant down – or a mistake on the part of Lawdogg. As Motor Authority points out, such an error could be something as simple as the Z06's owner accidentally shifting to first rather than third during his 35-mph pull. If, however, there's a deeper manufacturing problem with the Z06's engine, this might not be the only case we end up hearing about.
