GM Ultium tech can scavenge heat from everywhere, even you

GM likes to give us tidbits about its Ultium platform from time to time, and today it’s telling us about the platformÂ’s ability to capture waste heat from the propulsion system. In addition to capturing from the propulsion system, it can also capture humidity from both inside and outside the vehicle and even from passengersÂ’ body heat. Yes, you, your family and/or your friends are a usable heat source as far as GM EVs are concerned. It then deploys the heat in an advantageous way. If at this point, youÂ’re screaming, "Heat pump!" youÂ’d be right. WeÂ’re talking about an elaborate heat pump system that GM is using for its Ultium-based vehicles. Every Ultium-based GM vehicle gets this system that is covered by 11 patents and four publications. The waste heat it collects is used in a number of ways, but its primary use is to heat the cabin quickly and efficiently. GM claims it can heat the cabin of its Ultium-based vehicles quicker than vehicles with traditional internal combustion engines. Plus, when put to use, GM claims that using the heat pump provides its EVs with up to 10% more range than theyÂ’d have without. Beyond heating the cabin, the heat pump is capable of putting waste heat to use by preheating the battery prior to charging so that you can charge quicker. The system can even cool the propulsion system in preparation for Watts to Freedom (WTF) launch control starts. GM says this was vital in helping the Hummer EV achieve its bonkers 0-60 mph time of about 3 seconds. “Having a ground-up EV architecture gives us the freedom to build in standard features like UltiumÂ’s energy recovery capabilities,” said Doug Parks, GM executive VP of global product development, purchasing and supply chain. “This helps us squeeze more efficiency, performance and overall customer benefit out of our EVs.” GM says itÂ’s been developing heat pump technology since the EV1 and its heat pump. This is the modern evolution of that technology, and GM says itÂ’s going to be implemented in every Ultium-based vehicle as a standard feature.

GM execs fired over fraudulent India emissions testing

General Motors hadn't had a recall in India since 1995. That changed when it was discovered that certain employees were playing tricks with local emissions testing in order to ensure passing grades for engines. More than ten GM Powertrain employees in India and the US have been let go over the ensuing emissions flap, including Sam Winegarden, VP of global engine engineering, a man who has been with the company since 1969, leading development of some marquee powerplants.
According to Automotive News, an internal investigation revealed that employees "violated testing procedures," sometimes swapping specially prepared low-emissions engines during testing regimes for the Chevrolet Tavera SUV equipped with the 2.0-liter and 2.5-liter engines. Employees were also manipulating weights in order to get vehicles placed into different emissions categories. The discovery has led to GM recall the 114,000 Taveras produced over an eight-year period and halting their production and sale.
The Economic Times of India reports that the issue is due to "a faulty component." GM has developed a solution to the issue, and once it is validated in testing and approved by the Indian authorities, the recalled vehicles will be fixed at dealers and production will resume.

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.
