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 powertrain technical details

The last time General Motors launched a Chevy Volt, it was operating without really knowing how people would use the plug-in hybrid. Sure, it had experience with the EV1, but the Volt was a new kind of car, and you can see in the archives just how much time GM spent explaining this fresh, new powertrain to potential customers. Then, once the vehicle was released, the company collected voluntary data from a large number of owners to learn about their driving and charging habits. The company also asked them what they wanted most in the new version. There's got to be an algorithm buried somewhere in GM headquarters that was used to take all of the numbers GM collected and spat out the headline figures for the 2016 Volt: 50 miles of EV range and 41 miles per gallon. Another important number – price – is something GM isn't talking about yet (expect it in April or May), but the company is sharing some powertrain details about the upcoming car. At a preview lunch in Detroit last week for the SAE 2015 Hybrid & Electric Vehicles Technologies Symposium that's happening now in California, GM engineers Peter Savagian (who is presenting a paper on the new inverter used in the updated Volt) and Tim Grewe (talking about the entire second-generation powertrain) sat down with AutoblogGreen to tell us about the Volt's all-new propulsion system: The overall gist is that the new Voltec 5ET50 drive unit is lighter, smaller and more powerful thanks to a redesigned two-motor traction drive. As previously reported, the new engine is a 1.5-liter DOHC four-cylinder that offers 101-horsepower (at 5,600 RPM). Grewe said it's "great for range extension." The electric motor side of the powertrain offers 149 motoring horsepower from a two-motor, continuously variable transaxle. Initially, the new engine will be made in Mexico. GM will move production to Flint, MI during the first year it makes the 2016 Volt. The battery is slightly bigger in the new Volt – 18.4 kWh compared to 16.5 in the current-gen – and will have less range variation in the cold. GM is also using more of the overall capacity in the pack in the 2016 Volt than in previous versions, but is not saying how much more. GM is not ready to publish acceleration times just yet, but the 2016 Volt has improved numbers, especially when going from 30-60 miles per hour. Most everything on the new powertrain has become more efficient compared to the first-gen Volt.

24 Hours of Le Mans live update part one

We tasked surfing journalist Rory Parker to watch this year's live stream of the 2016 24 Hours of Le Mans. What follows is an experiment to experience the world's greatest endurance race from the perspective of a motorsports novice with a profanity-laden stream-of-consciousness writing style. Parker lives in Hawaii and spends far more time spearfishing than behind the wheel of a car. Jump ahead to Part Two here, and Part Three here. Big Money and billionaire hobbyists and rockets on wheels. Jets belching French color smoke overhead. Balance of power fuckery. Plenty of water on the ground this morning. Absurdly expensive motorcars lined up in the pissing rain. Fast twitch lunatics behind the wheel. Chomping at the bit. Let's go let's go let's go! Race hasn't even started, Ford #67 maybe dealing with clutch issues. Karma? That beautiful bastard Brad Pitt's out on the track, waving the tricolor flag. It's a standing start in "Noah's Ark" weather and the 2016 24 hours of Le Mans is go! First lap takes place behind the safety car, finished in a record setting 8 minutes 27 seconds. Wrong kind of record maybe, but this is the first time I've set my mind to watching the whole damn race. Feel like I'm part of history. 3:00 AM on Kauai, a little too early for life. Sucking down coffee like a maniac. Don't fall back asleep. Got my hands on four hours of rest, how much more can I need? Better be enough for the next twenty four hours. Gonna get kinda punchy toward the end. Jason Statham on the scene. Four feet of solid muscle, non-existent hairline. Lovely wife peanut gallery sitting next to me calls him the "best race car drive in the world." Not sure if she's serious. Toss up, could go either way. Statham's a funny guy. Heir to the Bruce Willis comedy action crown. Really good in the movie where the fat comedy lady plays a spy. Ford's on the road. Problems with gearbox pressure, apparently. Nearing a half hour in and the safety car is still on the track. Hellish amounts of water on the ground, in the air. Visibility is garbage. Getting better. Twitter wags, "Not with a bang but a whimper." Just building suspense. Mother Nature felt like killing some people today, race officials need to dial back the drivers until it dries a tad. Normal inclination would've seen 'em flying, guaranteed early lap wrecks. Sad news for that bloodthirsty part of my lizard brain I try and keep suppressed. Good news for humanity. #12 in the pit for a bit.
