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.

Almost half of US Cadillac dealers say no to ELR plug-in hybrid

If you've got $75,995 (or so) burning a hole in your pocket and a hankering for the new Cadillac ELR, you'd better call your local dealer before you burn up shoe leather and gasoline to head down there. According to a report on Edmunds, only about 56 percent of the brand's 940 dealers have signed up to carry the premium plug-in hybrid. As much as we'd like to see the more affluent among us driving on electricity, we can certainly understand the dealers' apparent lack of enthusiasm. The article cites costs of up to $15,000 for tools and training to sell the ELR. Show floor real estate is another consideration for dealers who aren't enthusiastic about sacrificing space for a for a vehicle with initial sales – just 46 units nationwide in the first two months, but that volume is expected to increase – that are as mediocre as our first drive impressions. Still, for those locations that co-habitate with Chevrolet dealers who already participate in the Volt program, the extra expenditure shouldn't be too onerous. The two vehicles share the same basic electro-mechanical drivetrain, so those dealerships should have most of the needed infrastructure already in place. The bulk of ELR sales, according to Cadillac's global marketing director Jim Vurpillat, are expected to be in along the coasts, in places like California, Miami and New York.

Cadillac moving back to Detroit after four years in New York City

After four years in New York City, The Wall Street Journal reports that Cadillac is moving its headquarters back to Detroit. This comes about four months after former head Johan de Nysschen was ousted from the automaker for a variety of reasons, including slumping sales and a product line not in concert with consumer tastes. It's also months after a Cadillac spokesperson told The Detroit Free Press that "It's 100 percent that we're staying [in New York City], that was never a question." Let's be clear about this, the move to New York was not Cadillac's biggest issue. As contributing editor James Riswick reminded us this morning, "the decision to sell three similarly sized large sedans, a variety of obsessive BMW-fighting cars, and only one crossover was not done while they were in New York." That was all planned years ago, before de Nysschen ever joined the company. He may not have righted the ship, but he didn't set it on its course. Note that the XT4, Caddy's second crossover after the SRX-replacing XT5, is just now hitting the market. The move to Manhattan was meant to give Cadillac more autonomy and put its leadership in a place where they could get a sense of what a luxury car buyer wants and needs. Detroit is great, but it can be an echo chamber, especially in a company as large and storied as General Motors. The problem is that Cadillac still relies heavily on Detroit and that poor communication was slowing development, according to the report. Steve Carlisle, a long-time GM employee, took over the brand after de Nysschen was let go. He and more than 100 others work in New York. Related Video:
