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.

Hear the new Cadillac CTS-V torture some tires

The 2016 Cadillac CTS-V seems like the type of wonderful gift that Santa might cook up in his workshop for one extraordinarily good boy or girl. However, the first chance for most people to actually see the super sedan and its carbon fiber pieces in real life is at the 2015 Detroit Auto Show in January. As a stocking stuffer until then, Caddy has released this video highlighting the latest V-Series roasting its tires better than any dinner for the holidays. With the supercharged 6.2-liter V8 from the Chevrolet Corvette Z06 nestled into the CTS-V's engine bay, the Cadillac certainly has quite a bark coming from its exhaust. The mill might be detuned slightly from the 'Vette to 640 horsepower and 630 pound-feet of torque, but that's still plenty for this smoky application. Enjoy this tease of the future V-Series, ahead of the Detroit show.

2021 Cadillac Escalade Interior Review | Tech-forward fortress

Of all the interiors that are vital to Cadillac’s success, the new 2021 EscaladeÂ’s is arguably the most important. ItÂ’s supposed to be the best GM can muster, and the previous generation was a distant second to the classically elegant Lincoln Navigator. Cadillac didnÂ’t try to copy LincolnÂ’s success with its redesigned full-sizer, instead opting to follow a more generic theme of tech-forward luxury. When we say tech-forward, though, we mean it. The 38 inches of curved OLED screens we covered in our Escalade infotainment review absolutely dominate the dash in a brazen display of opulence. There isnÂ’t much room for anything else to take center stage, but whatÂ’s there is extremely nice. Large swaths of wood trim stretch across the dash and also adorn a substantial part of the center console. ItÂ’s harder to find something that doesnÂ’t feel like soft-touch leather, wood or metal trim than it is to find cost-cutting materials. There are certainly some areas with the usual black plastic for buttons, but every car company that isnÂ’t Rolls-Royce resorts to plastic at some level. The seating position and ergonomics of the Escalade are a big step up from past models. There was a feeling of claustrophobia in previous Escalades with the whole interior being built up around the driver in an unfriendly manner. This Escalade tones that down with lower and flatter surfaces, along with just being bigger in general. That feeling of expansiveness is great for decompressing and relaxing in the available heated, cooled and massaging seats. Riding in the back is almost as lovely. Switching to an independent rear suspension and making the vehicle longer means more passenger and cargo space (10.3 cu-ft more than before with the third row up). The majority of this is realized in the third row (10.4 inches more than before), where even large adults can sit comfortably with a laid-back seating position. Before, if your knees weren't in your face, it's probably because you gave up and hitched a ride with someone else. A BMW X7 or Mercedes-Benz GLS will still outclass it for materials and third-row features, but the Escalade wins on sheer bigness. Getting back there is a breeze with a huge walkway, though putting the seat back into place is borderline annoying, requiring much more physical effort than a powered second row would. As big as the third row is, sitting in the second row is even better thanks to the massive dual screens mounted to the front headrests.
