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.

2017 Chevy Bolt EV arrives in late 2016 with 200-mile range

For those keeping track, the production 2017 Chevy Bolt that was just revealed at CES in Las Vegas is, well, pretty much just what we were expecting. As promised, GM claims the EV crossover-ish hatch will have a 200-mile range, and be "affordable." While pricing hasn't been announced, we've posited in the past that "affordable" is code for around $30,000 after incentives. The Bolt will use a couple of features, both novel and expected, to enhance range. The EV is expected to use information on the owner's driving history, the weather outside, the terrain, and even the time of day to help manage and predict range. The nav system will optimize routes to conserve range, if needed, and show nearby charging stations. That should ease, if not eliminate, range anxiety. Another range-conserving feature is a low-draw Bluetooth system. Speaking of charging stations, there's no word so far about how long it'll take to recharge a Bolt, or the capacity of the battery pack. Inside, the large center-mounted MyLink screen measures a full 10.2 inches, and provides a display for the wide-angle rear camera with a birds-eye view capability. OnStar provides 4G LTE and a wifi hotspot to occupants, and the sorts of efficiency and driving habit apps you'd expect will be available. It seems like remote start and cabin preconditioning will be standard. Interestingly, the Bolt will feature "Gamification" features intended to promote efficient driving by pitting Bolt drivers against each other for green driving awards or rankings. Details on are sparse on this feature, but then again, information on the Bolt in general is a little sparse right now. If you want to know things like detailed specs, the specifics of chassis componentry, or even trims and options, you'll have to wait. Check out our first quick spin of a prototype Bolt in Las Vegas for a preview of what GM's EV is like on the road. Chevrolet Introduces 2017 Bolt EV First long-range, affordable EV with customer-focused connectivity LAS VEGAS – Chevrolet is introducing the 2017 Bolt EV at the Consumer Electronics Show, fulfilling its promise to offer a long-range, affordable electric vehicle for the masses. The Bolt EV, which will go into production by the end of 2016, will offer more than 200 miles of range on a full charge. It also features advanced connectivity technologies designed to enhance and personalize the driving experience.

Mother's Day Suggestion No. 2,506

With Mother's Day coming up, we're always looking for new gift ideas to celebrate the occasion, but hot laps around a track might not be the best suggestion for Darius Khashabi. In a video posted on YouTube, Khashabi straps his mom into the passenger seat of his C6 Corvette Z06 for some laps around Sonoma Raceway (formerly Infineon Raceway) at "60 percent" with comical results.
Now this isn't the first time Mama Khashabi has gotten seat time in her son's car around a track, as his YouTube page shows him pulling a similar stunt - with similar results - around Mazda Raceway Laguna Seca last year. Scroll down for the video, but know that the action really gets going at around the 1:40 mark.
