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.

2016 Chevy Volt ads strike frustrating, yet familiar, chord

Sometimes, it's hard to let go. In the six years that GM has been advertising and selling the Chevy Volt, one dominant message is that the car is an EV without any range anxiety. On the one hand, this is a positive thing: our car does something that other electric vehicles don't. Of course, there's another, more reasonable take on the message that EVs only equal limited range: don't promote this viewpoint if you ever plan on selling a pure EV. But, of course, this is exactly what GM is doing with a new ad for the 2016 Chevy Volt. Called Elevator, the spot (watch it above) compares driving an all-electric car with riding in an elevator getting stuck. Your Nissan Leaf might run out of electricity, the ad says, and that would be as uncomfortable as being trapped between floors. The main problem, of course, is that Chevy also offers the Spark EV and is getting ready to sell the Bolt EV. Does the company think that everyone will forget these anti-EV commercials when it come time to shop for a Bolt? Even worse, does GM think we've forgotten the Anthem ad for the Volt back in 2010? Apparently, so. Elevator isn't the only ad for the 2016 Volt that GM debuted today. The other, called Time Capsule (below), takes a swipe at the Toyota Prius. Trouble is, there are two easy ways to dismiss this ad as well. First, and most obviously, if GM is against using old technology, then why does it continue to shove a 100-year-old fossil fuel engine into almost every car it builds? Second, attacking the Prius for using 15-year-old tech – when said tech is still able to mop the floor with any hybrid from GM in the fuel economy race - is more like an admission of defeat than anything to be proud of. "Hey look, the Prius uses technology from the '90s," GM says. To which the observant viewer will ask, "Well, then why can't you build a 50-mile-per-gallon hybrid, GM?" It's also worth noting that Chevy has been on a misguided advertising streak as of late. We bashed their ads that suggested its Silverado is better than the F-150 because it uses steel instead of aluminum, too, especially since those commercials used shark cages and stupid superhero costumes in an attempt to make a point. Chevy, stop assuming we're all idiots. Please. Now, the 2016 Volt is a great car and I know that GM can make a darn good Volt ad (like this one), so seeing the company shoot solid fuel-efficient technologies in the back (again and again) is just frustrating.

Diesel details: Comparing Ram 1500 EcoDiesel, Chevy Silverado Duramax, Ford F-150 Powerstroke

With specifications for the 2019 Ford F-150 Power Stroke diesel already out, and the details on the 2020 Ram 1500 EcoDiesel and Chevy Silverado Duramax (and its GMC Sierra twin) trickling out, we felt it was a good time to start comparing the full-size trucks' light-duty diesels. Bear in mind, we've only driven one of these new diesel trucks, so we'll be sticking to numbers for now. Some numbers haven't been announced yet, either, but stay tuned, because we'll be updating this post with additional specifications as they become available. And if you want to compare any other versions of these trucks with other vehicles, be sure to check out our comparison tool. Now let's start comparing, starting with our big chart of numbers below. As we can plainly see, these trucks are quite closely matched. Each one has six cylinders, a displacement of 3.0 liters and a turbocharger to boost it. The output of each is somewhat close, too. The Ram 1500 EcoDiesel is the torque king at 480 pound-feet, 20 more than the GM trucks and 40 more than the Ford. The GM trucks win on power, though, with 277 ponies, 17 more than the Ram, and 27 more than the Ford. GM does report that you get their trucks' peak 460 pound-feet of torque from 1,500 rpm to 3,000 rpm, whereas the others only report peak torque at a particular point in the rev band, but all of these trucks should have wide, flat torque curves as you would expect from modern turbodiesels. 2020 Ram 1500 EcoDiesel View 8 Photos Engine output is only one part of the truck performance equation. We also have towing and payload capacity, as well as fuel economy. With towing, the Ram 1500 is the current leader with a maximum capacity of 12,560 pounds. That tops the Ford F-150's 11,400-pound tow rating by well over 1,000 pounds. The F-150 can carry 2,020 pounds in its bed, but we don't know yet whether that's better or worse than the Ram or the GM trucks. We also don't have numbers for the GM trucks' towing capacities. View 9 Photos As for fuel economy, the Ford F-150 manages a thoroughly impressive 22 mpg in the city and 30 on the highway with two-wheel drive. Choosing four-wheel drive drops those numbers to 20 and 25 respectively. The fuel economy numbers for the Ram, Chevy and GMC haven't been revealed yet, but for some comparison, we can look at the old Ram EcoDiesel. That truck's best fuel economy was 20 in the city and 27 on the highway with two-wheel drive.
