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.

2021 Cadillac CT5 Review | Is the price (and size) right?

The Cadillac CT5, which was brand new for the 2020 model year, took the place of the CTS in General Motors’ luxury sedan portfolio. Its mission is the same as the car it replaced: compete on equal footing with the German trio of Audi, BMW, Mercedes-Benz along with Japanese brands Acura, Infiniti and Lexus. But it does so with a radically different package than the CTS. In place of the sharp corners and angular greenhouse of its predecessor is a smoother sedan with a flowing fastback shape. The new CT5 is also around $10,000 cheaper than the CTS it replaces, despite the fact that the two are within a few inches in exterior dimensions. So while it may be sized similarly to the cars it used to compete with, including the BMW 5 Series and Mercedes E-Class, it's now priced like a 3 Series or C-Class.  Clearly, Cadillac thinks this refined strategy will position the CT5 to better compete against those established luxury players. The car itself drives quite well and is stylish, well equipped, and that price-to-size ratio gives it a unique proposition to attract buyers away from the Europeans. What's new for 2021? The CT5 finally gets CadillacÂ’s Super Cruise semi-autonomous technology for 2021. It's the latest version that includes Lane Change on Demand functionality, but itÂ’s only available on Premium Luxury and V-Series trim levels. CaddyÂ’s sport sedan also gets a 12-inch digital gauge cluster with multiple themes, including a Track theme on the high-performance CT5-V. A new Diamond Sky special edition package will be offered on Premium Luxury CT4 and CT5 models, adding interior and exterior styling upgrades along with all-season run-flat tires on unique wheels. Additional updates include wireless Apple CarPlay and Android Auto, and a console-mounted rotary infotainment knob that enables left and right clicks to more easily navigate the infotainment system. 2020 Cadillac CT5 View 22 Photos   What's the CT5Â’s interior and in-car technology like? The Cadillac CT5 interior can best be described as “nice enough.” Unfortunately, "nice enough" isnÂ’t quite good enough to compare favorably with Audi, BMW, Mercedes-Benz or Volvo. We'd say it's not good enough to compare with cross-town rival Lincoln, either, but they won't be selling sedans in 2021.
