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.

2016 Chevy Volt will have more EV range, bigger battery

Meet the new Volt, not the same as the old Volt. That appears to be the story when General Motors introduces the 2016 Chevy Volt at the Detroit Auto Show in January. Today we're getting some more details on the guts of the new plug-in hybrid, and it turns out they're going to be much improved from the current Volt, which first went on sale at the end of 2010. Sure, the first-gen Volt did get some improvements along the way (a slightly larger battery pack, lane departure warnings) but the new Volt – which will go on sale in the second half of 2015 – marks the first time GM has been able to return to the drawing board and really make the improvements that its customers want. That's how Larry Nitz, GM's executive director of vehicle electrification explained it to AutoblogGreen today when explaining the all-new Voltec extended range electric vehicle (EREV) powertrain. "In the Gen 2 is we gave the engine a little more power, a little more torque, a little more displacement, more capability." – Larry Nitz Nitz said that the new Volt will be better in almost every sense: a bigger battery, longer EV-only range, 20 percent better acceleration in the low speed range and higher overall efficiency. This is due, in part, to the Volt's two motors being able to both act as generators and power the car. As we noted this morning, the 2016 Volt will use a larger, 1.5-liter four-cylinder engine, a version of which is already used in the Chinese-market Cruze. Nitz said that this has a number of benefits, including more power and quieter operation. "Some people would say, why did you make [the first-gen engine] so big. I would say, why did you make it so small?" he said. "It works good, our customers love it, but the reality is that if you go a little bit off and use the car a little harder, you can get the engine to need to operate at a higher speed. In an EV, that's quite noticeable. So, what we did in the Gen 2 is we gave the engine a little more power, a little more torque, a little more displacement, more capability and what it has marginally enabled is not only is it more efficient but it's also quieter." Nitz wouldn't talk about how the new powertrain might affect the two other products that use the Volt's underpinnings – the Cadillac ELR and the Opel Ampera – but if you've got a quieter option, we assume that's something ELR drivers would enjoy. But that's a story for another day.

That time we lapped Indy with Tony Kanaan in a Corvette Z06

We're here in Indianapolis, IN, attending this weekend's 99th running of the Indy 500. The big event happens tomorrow, but the city is buzzing today with all sorts of pre-race festivities. For us, that means checking out Indianapolis Motor Speedway a day early, and getting a hot lap around the racetrack in the official Indy 500 pace car – a 2015 Chevrolet Corvette Z06. Our driver for the occasion is IndyCar racer Tony Kanaan, who won the Indianapolis 500 in 2013. Of course, he'll be competing tomorrow, leaving pace duties to none other than Jeff Gordon. Check out our minute-and-a-half-long lap of the Indy 500 track in the video above, where Kanaan hugs the wall in true race style, getting the Z06 past 150 miles per hour on the back straight. Stay tuned for more Indy 500 coverage later this weekend.
