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.

Rumor: 2016 Chevy Volt gets 53 miles EV range, 40% increase

While we're still waiting for the official word from GM, news is creeping around the Internet that the 2016 Chevy Volt will get a big boost in all-electric range and gas-burning efficiency. According to new rumors out today, the second-gen Volt will be able to go 53 miles on a full charge, have 106 MPGe and be able to get 42 miles per gallon on the official EPA numbers. Compared to the outgoing first-gen Volt (38 miles EV range, 98 MPGe, and 37 mpg) these are all impressive increases. The all-electric range boost of almost 40 percent is the biggest surprise, though. We knew the new Volt would get better numbers than the first-gen model, but when GM debuted the car in Detroit earlier this year, it said it suspected the Volt would get a 50-mile range, 41 mpg and 102 MPGe. We'll be keeping an eye out for official confirmation of all these new numbers. Volt drivers are already making most of their driving miles electric. The number sits at about 80 percent currently, and GM has said it expects this to climb to 90 percent in the new model. GM said in May that the 2016 Volt will start at $33,995, a bit lower than the current Volt's MSRP of $34,170 before any tax breaks. So, for less money you'll be getting much better fuel economy. What's not to like about that? Preorders are already open for interested buyers in some parts of the country.

2017 Chevy Bolt charged up for production

Chevy's decision to call its new electric car the Bolt has stirred controversy and confusion, but regardless, it's well on its way to becoming a production reality. The prototype captured in these shots is heavily camouflaged, but the crossover/hatchback styling cues are still evident. The car also has a tall greenhouse, slight creases in the sides, and a sloping roofline in back. There's a rapidly rising body line that makes for less glass for rear passengers, but that's probably part of the camo. The Bolt is expected to arrive for 2017 and will be sold in all 50 states. The Chevy Bolt carries the promise of bringing EV technology to a broader audience. Chevy said the car will cost about $30,000 after possible tax incentives and could have a range of 200 miles. It will be assembled at General Motors' Orion Assembly factory north of Detroit. The Bolt will augment the plug-in hybrid Volt in Chevy's green fleet, and it will compete against vehicles like the BMW i3 and Nissan Leaf. Related Video:
