Minor updates coming to 2017 Chevy Volt

The 2016 Chevrolet Volt has just appeared at dealerships, but already the talk has turned to the mildly updated 2017 model going on sale in a few months. The new Volt has already won the 2016 Green Car of the Year award and is sparking a noticeable uptick in sales over the outgoing model. Chevy is now planning to keep interest in the second-generation Volt strong with some tweaks and increased availability. The main equipment change to the 2017 Volt will be the option of adaptive cruise control on both the base LT and uplevel Premier, according to CarsDirect. While the Volt already offers safety technology such as blind-spot monitoring and forward collision warning, adaptive cruise has been conspicuously absent. But the largest change will be that the 2017 Volt gets nationwide availability. GM decided to focus on strong markets for the original Volt when it chose where to introduce the new model. Buyers interested in the second-generation model have until now been limited to making purchases in states such as California, Maryland and the Northeast. This will all change soon. Conversely, you can have a 2016 Nissan Leaf now in all 50 states, or a 2016 Toyota Prius very shortly. But in our first drive of the Volt, we found it to be, "an efficient, no-compromise EV" and worth the wait for those who don't live in the states with the strictest emissions laws. Perhaps the reason the 2016 Volt is already being given an injection of dealer incentives is because of its relatively short lifespan. The 2017 Chevy Volt should arrive on dealer lots by spring 2016.

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.

Chevy teases next-gen Volt at fan event in LA

Barely two months before its planned debut at the 2015 North American International Auto Show, Chevrolet has released yet another batch of teaser images of its second-generation Volt. Unlike the first image, though, which just showed the car's rear badge, there's a lot more to this quartet of shots. The first three images show off the nose of the next-gen model and come from a fan event in Los Angeles. What we can see is a sleeker front end, with an evolution of the silver grille inserts previously seen on the original Volt and Spark EV. Gone is the current car's split upper grille, in favor of a more conventional arrangement. The sharper, more angular headlights are also an evolution of the lamps seen on the current Volt. Chevrolet also took the opportunity to announce a new location-based charging system that uses GPS to adjust the vehicle's charge settings, including the charge level, while also announcing that the next-gen car will feature more intuitive charge indicators that will be better able to inform owners of their car's charging level. The tech will mean that the Volt 'knows' when it is parked at home, and can thus automatically optimize charging for off-peak times, and so on. Take a look at the teaser images at the top of the page, and then head below for Chevy's press release announcing the new features. Next-Gen Chevy Volt Offers More User-Friendly Charging 2014-11-20 GPS makes charging more convenient Portable charger is easier to access Intuitive visual cues show charge status DETROIT – If there's one thing Chevrolet Volt owners love about their cars, it's being able to recharge the battery easily. Evidence of that is a U.S. Department of Energy study that shows more than 80 percent of all trips by Volt owners did not use the range extender. Chevrolet has made the charging system in the next-generation Volt even easier for customers to recharge the battery – and to check the charge status. The next-generation Volt debuts in January at the North American International Auto Show. "Chevrolet used the real-world experiences of today's Volt owners to make the charging process simpler and more convenient in the next-generation Volt," said Andrew Farah, chief engineer for the Volt.
