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 follows up Lambda CUV stop-sale with tire recall

In late January, General Motors announced a stop-sale for about 6,281 examples of the 2015 Chevrolet Traverse, GMC Acadia and Buick Enclave because of the possibility for the treads cracking on their 18-inch Goodyear Fortera HL tires. At the time, GM said that this would also eventually lead to a safety campaign to repair the problem, and the National Highway Traffic Safety Administration has just published those details. GM's recall covers 5,876 of the three Lambda platform crossovers to replace their tires. According to NHTSA, if the treads crack, there could be a loss of pressure and possible failure. Goodyear already announced its own recall of the tires after internal testing found small tread cracks. The company did not believe this was safety issue, but the problem did put the rubber out of compliance with federal laws. The business's safety campaign covered an estimated 48,512 tires. Of those, around 32,000 were reportedly made for GM to either be fitted to vehicles or sold as replacements. The remainder went to the aftermarket. Goodyear's portion of the recall is expected to begin around February 20. RECALL Subject : Tire Tread Cracking/FMVSS 110 Report Receipt Date: JAN 28, 2015 NHTSA Campaign Number: 15V044000 Component(s): TIRES Potential Number of Units Affected: 5,876 All Products Associated with this Recall Vehicle Make Model Model Year(s) BUICK ENCLAVE 2015 CHEVROLET TRAVERSE 2015 GMC ACADIA 2015 Details Manufacturer: General Motors LLC SUMMARY: General Motors LLC (GM) is recalling certain model year 2015 Buick Enclave vehicles manufactured December 9, 2014, to January 14, 2015, 2015 Chevrolet Traverse vehicles manufactured December 9, 2014, to January 20, 2015, and 2015 GMC Acadia vehicles manufactured December 9, 2014, to January 16, 2015, and all equipped with Goodyear P255/65R18 Fortera HL tires. These vehicles are equipped with tires that may experience tread cracking. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) No. 110, "Tire Selection and Rims and Motor Home/Recreation Vehicle Trailer Load Carrying Capacity Information for Motor Vehicles with a GVWR of 4,536 kilograms (10,000 pounds) or Less." CONSEQUENCE: If the tire treads crack, a loss of tire pressure and possible tire failure may result, increasing the risk of a crash. REMEDY: GM will notify owners, and dealers will replace the tires that were manufactured within a specific date range, free of charge.

2020 Ford Escape hybrids vs other crossover fuel sippers: How they compare on paper

Along with a new generation of Escape, Ford also reintroduced the world to the 2020 Ford Escape Hybrid. And if that weren't enough, Ford is adding a plug-in hybrid version. This is a sign of the times: people are more crossover crazy than ever, but are also seeking ways to use less fuel, whether it's for environmental or purely money-motivated reasons. The Ford hybrids aren't the only fuel-efficient compact crossovers on the market. They will be going head-to-head with conventional hybrids including the 2019 Kia Niro, 2019 Nissan Rogue Hybrid and 2019 Toyota RAV4 Hybrid. There are other plug-in hybrids including the 2019 Subaru Crosstrek PHEV, 2019 Mitsubishi Outlander PHEV and the plug-in version of the 2019 Kia Niro. There are even a couple diesels in the form of the 2019 Chevy Equinox and 2019 GMC Terrain. So we've rounded up the details on all these crossovers to see who leads and lags in criteria such as power, fuel efficiency, space and price. Check out all their details below. 2019 Subaru Crosstrek Hybrid View 68 Photos How do their engines and fuel economy compare? Conventional Hybrids and Diesels Let's face it, if you're buying one of these crossovers, one of the things that matters most to you is just how frugal with fuel they are. We'll start off with the conventional hybrids and diesels, and the clear victor is the Kia Niro, which in base FE trim, manages to hit 50 mpg combined. This is thanks to it sharing its powertrain with the Hyundai Ioniq, the Hyundai equivalent of the Toyota Prius. Buyers should take note that only the FE returns such high fuel economy. The LX and EX drop to 49 mpg, and the S Touring and Touring get 43. Even then, the least efficient Niro is the most efficient of the normal hybrids and diesels. It is nearly the least powerful, though, with 139 horsepower. Just behind it is the Toyota RAV4 Hybrid. It delivers 40 mpg combined, and it has an ace up its sleeve: it comes standard with all-wheel drive. Every other vehicle in this powertrain group has front drive standard, and the Niro isn't available with all-wheel drive at all. If that weren't enough, the RAV4 Hybrid also boasts the most power at 219 horses. While we can't say anything about Escape Hybrid fuel economy, we do know that it will make 198 horsepower, which is close to the class-leading RAV4. The least powerful of these is the Equinox and Terrain, and they return the worst fuel economy at 32 mpg.
