How real is the Chevy Bolt EV and will it really cost $30,000?

"This is us bragging that we can do this kind of car." That's how Michael Simcoe, GM's executive director for NA exteriors, described the Chevy Bolt EV concept, which made a surprise appearance at the Detroit Auto Show today. While there was talk of a 2017 production debut, this is for sure a concept vehicle. But that means the ideas behind the vehicle are perhaps more important than the details. For example, no one is talking about what size battery might appear in a production Bolt, but Simcoe would talk about how rapid progress in battery improvements made it possible for GM to make the bold Bolt declaration that promises 200 miles and a price tag of around $30,000 (after incentives). But if the Bolt makes it to market, it won't be until 2017 (as rumored) or later, is it really fair to promote the car as being available with a federal tax credit? For one thing, credits for plug-in vehicles may change in the next few years, but if the laws stay the same, each manufacturer is limited to 200,000 vehicles before the credits start to decline. GM is justifiably proud that it's sold over 70,000 Volts thus far, but with a new model coming out later this year and a few years to go until the Bolt potentially arrives, GM could be pushing right up against that 200,000 limit when the Bolt goes on sale. But Volt executive chief engineer Pam Fletcher told AutoblogGreen that, "We're just trying to take some of the confusion out." "Think about talking to the average consumer," she said. "First, going through the explanation of how the federal tax credit was set up, how it's being used and so on. [In the industry, we] have the luxury of understanding the nuances of that regulation, but right now people who aren't in the marketplace, they don't have the luxury of all that. It's already hard to communicate the details so we gave them data in a way that is what they're used to seeing." There was one question that drove the two-year Bolt gestation and design period, Simcoe said: What does a better battery offer a vehicle designer? "We've got a number of spaces we play in for powertrain technology and obviously electrification is one of them," he said. "With Volt 1 and then the Spark EV, with that development and batteries getting better for us, we started doing some practical packaging to deliver a vehicle which was not the traditional aero form which you see around electric vehicles.

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.

NHTSA closes book on Ford, GM probes of 600,000 vehicles

US safety regulators have closed a pair of investigations into some 500,000 Ford Crown Victoria, Mercury Grand Marquis and Marauder sedans built between 2004 to 2007, and 100,000 Chevrolet Impala models from 2014. The Ford investigation focused on rusting heat shields, which may become dislodged and jam the steering, according to Reuters. The National Highway Traffic Safety Administration found that this happened very rarely. In fact, of the ten incidents filed with the government safety watchdog, six came from a single police department, which evidently had some sort of problem with its reporting. As for the Impala, the NHTSA investigators attributed two incidences of "unintended autonomous braking" to user error. In both cases, the vehicles were involved in rear-end collisions. According to GM investigators, it's believed that drivers accidentally activated the electric parking brake, causing the collisions. The vehicles in question were rental cars.
