Chevy Spark EV could be coming to Midwest later this year

Ohio is not known as a hotbed of EV sales – if anything, the state is a bit anti-EV, thanks to a legislative fight against Tesla's direct sales model – but it might be on Chevrolet's short list to expand the market for the Spark EV in the near future. The latest official GM press release on the battery-powered Spark still says the car is "available exclusively in California and Oregon," but Hybrid Cars found four Ohio dealerships that list a Spark EV on their websites, with hints the the car will be coming to the Midwest state by the end of the summer. See, for example, here, here, here and here. But that's probably not going to happen, according to Randy Fox, GM communication's manager for passenger cars. Fox told AutoblogGreen that, "At this point in time, we don't have any official plans to expand the Spark EV beyond California and Oregon." The reason is that California and Oregon have the infrastructure to support EVs, Fox said, and GM wants to be able to support its EV customers. "We are continuing to look at other options," he said. "The selling point for electric cars today is not advertising, it's eyeballs, it's peer exposure" – John O'Dell John O'Dell, a senior editor at Edmunds.com, told AutoblogGreen that, "It makes sense for [GM] to expand sales and it makes sense to do it in a quiet manner, to get these vehicles on the road. The selling point for electric cars today is not advertising, it's eyeballs, it's peer exposure. If someone in my neighborhood has one and he likes it, then maybe I can trust him. So it's important to get these vehicles on the road." Chevy sold 182 Spark EVs last month, a significant increase over the 98 sold in April. That's still small potatoes compared to the 3,000+ Nissan Leaf EVs sold last month, but making the electric Spark available in Ohio, say, or GM's home state of Michigan could boost those numbers. AutoblogGreen called a few dealerships in Michigan to see what they had heard. One salesman said he didn't think GM had started production yet but the inventory manager for another dealership said the Spark EV is scheduled to arrive in the Midwest in "roughly the fourth quarter." What would GM's incentive be to offer the car in markets outside of California where it can gain ZEV credits with each sale?

GM patent reveals new two-stage turbocharger

Modern turbochargers may be some of the best ever made, but performance is something that engineers are always trying to improve. According to GM Inside News, General Motors (GM) is hoping to alleviate some of the negative aspects of a two-stage turbocharger setup with a newly-patented design. The patent, that was filed on May 19, 2016, reveals a clever bypass system that allows the engine, a four-cylinder unit, to optimize both the low-pressure and high-pressure inlets for its respective functions. According to the filing, a conventional two-stage turbocharger setup is engineered to allow both turbines to operate simultaneously at low and mid engine speeds. At high engine speeds, only the low-pressure turbine works. The setup can't isolate either the low or high pressure side, which can impair low-end performance. GM's new two-stage turbocharger setup looks to eliminate this by linking the high-pressure turbo to the exhaust manifold through the high-pressure inlet duct. The low-pressure turbo is attached to the high-pressure turbo by a low-pressure inlet duct, which is linked to a connecting channel. A single actuator that is housed in the exhaust manifold creates a bypass that can opens the high-pressure inlet or close the connecting channel. Depending on what the engine load and speed is, the ECU guides the actuator—a single rotating spindle with discs corresponding to flanges on the high and low pressure sides—to isolate one of the two turbos. Isolating the turbos allow the respective inlets to be engineered for the best possible fluid dynamic performance. The setup should increase performance and decrease lag. There's no word on what car this setup will make an appearance on, but it will most likely be used in premium vehicles before trickling down to the rest of GM's vehicles.

Watch this week's Top Gear America used-car challenge

Top Gear America is back for the penultimate episode of the first season. Used car challenges were some of the highlights of the original UK edition. In our exclusive clip, Tom Ford, Antron Brown and William Fichtner run their $7,000 sports cars in a drag race. As expected, the trio chose very different cars for the challenge. Watch the video to see if a Subaru WRX's all-wheel drive can overcome a power deficit to beat a Ford Mustang and a Chevy Corvette. Brown and Fichtner also spend some time relaxing with an old Jeep Wagoneer. Like them, we're really hoping Jeep will bring back the Wagoneer nameplate. Brown also drives a Maserati Levante, proving that not all family cars need be boring. This week's guest star is actor, rapper and former host of Pimp My Ride, Xzibit. Top Gear America airs Sundays at 8 p.m. Eastern on BBC America. Related Video: Celebrities TV/Movies Chevrolet Ford Subaru Top Gear exclusive top gear america
