GM starting to talk seriously about 200-mile EV

We've been hearing word of a 200-mile EV from Chevrolet for a while now. First, there was General Motors then-CEO Dan Akerson hinting at a $30,000, 200-mile EV that would take the competition by surprise. Then Akerson confirmed that GM is working on a 200-mile EV in a speech in March. LG Chem, which supplies batteries to GM and other automakers, recently said it was working on batteries for EVs with a range of 200 miles. GM's head of global product development Mark Reuss just re-confirmed that there are plans for an EV with a 200-mile range, and sources have told Automotive News what that car will be. While Reuss didn't mention anything about a specific model or platform, two undisclosed sources with knowledge of GM's plans have said that an EV with a range of about 200 miles is indeed in the works, and that it will be based on the Chevrolet Sonic. The sources also gave a timeline for the car, saying it is slated for sometime in 2017. According to Reuss, the plan is for Chevy to offer a lineup of electric cars, with the 200-mile EV joining ranks of the Chevrolet Volt and the Spark EV. He didn't hint at a timeline, but if the sources are correct, we could see a Sonic EV being built within a few years. Reuss sees demand for it, too. When speaking of the Spark EV, currently only available in California and Oregon, he says that "people wish we would sell it all around the country." If he's right about that, it's not difficult to imagine people taking interest in Chevrolet's 200-mile electric car, whether or not it's a Sonic.

eBay Find of the Day: Mario Andretti's personal 2009 Corvette ZR1

With victory in the the Indianapolis 500, a Formula 1 World Championship, a win in the Daytona 500 and too many other motorsports accomplishments to list, Mario Andretti stands among not just the greatest American racing drivers of all time, but the greatest drivers, full stop. Apparently, the champ is also a fan of speed when not on the track, because now there's a chance to own what is said tobe his personal 2009 Chevrolet Corvette ZR1 with just 12,872 miles on the clock. The eBay Motors auction page clearly shows Mario Andretti standing with the car, but the rest of the ad is admittedly short on details. The vehicle history report lists only one previous owner – ostensibly Andretti. The exterior is a handsome Blade Silver Metallic accompanied by a Dark Titanium leather interior. However, the seller keeps additional information to a minimum as well with the description simply stating, "This 2009 Chevy Corvette ZR1 is owned by Mario Andretti and has been garage kept all its life. It is fully loaded with all option on this car." The future buyer will get a seriously great car along with some huge bragging rights at any party by touting its ownership history. We've reached out to the seller for more particulars and provenance, and will update this story if we hear back. In the meantime, the auction for this C6 ends on Thursday, January 8, and currently the reserve isn't met. The price sits at a hefty $68,100 as of this writing, with six bids registered.

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.
