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.

Cadillac prices the 2020 XT6 crossover from $53,690

Cadillac has announced official pricing for its new XT6 crossover, built in Tennessee. The three-row XT6, Cadillac's first big crossover, starts from $53,690 when it goes on sale later this spring. For that, Cadillac offers the "Premium Luxury" trim level model with front-wheel drive; AWD is optional. Above the Premium Luxury is the XT6 Sport, which comes standard with AWD and starts from $58,090. Both prices include destination charges. The sole engine at this point is the 3.6-liter naturally aspirated V6, which produces 310 horsepower and 271 lb-ft of torque; the transmission is a nine-speed automatic. The Premium Luxury and Sport differ visually, with the former offering more chrome and wood, while the latter has blacked-out trim in place of chrome and carbon trim instead of cabin wood. The wheel design is different between the trim levels, and the Premium Luxury has red taillights while the Sport version has clear tails. The Sport model has continuously adjustable shock absorbers. Both models have seven airbags as standard, as well as an HD rear camera, forward collision alert, automatic emergency braking and front pedestrian braking, front and rear park assist, lane change and blind spot alert, lane keeping assist and lane departure warning and rear cross traffic alert. The lighting is LED front and rear; inside, a heated steering wheel is standard, as is a power folding third-row seat and a remotely folding second-row seat. Seven-passenger seating is standard, and a six-passenger setup is optional with captain's chairs for the second row. There are option packages such as the Enhanced Visibility and Technology Package, which adds an eight-inch gauge cluster display and an HUD, both in color, HD surround vision with recording, and automatic parking assist with braking. The Driver Assist package adds adaptive cruise and enhanced AEB, and one can also specify night vision. The XT6 charges phones wirelessly and is Apple CarPlay and Android Auto compatible as standard. It also has a 4G LTE Wi-Fi hotspot with 3GB or three months' worth of data thrown in, and phones are paired via NFC. Cadillac is taking orders for the XT6 starting in March.

Teaching autonomous vehicles to drive like (some) humans

While I love driving, I can't wait for fully autonomous vehicles. I have no doubt they'll reduce car accidents, 94 percent of which are caused by human error, leading to more than 37,000 road deaths in the U.S. last year. And if it means I can fly home at night in winter and get safely shuttled to my house an hour-plus away — and not have to endure a typical white-knuckle drive in the dark with torrential rain and blinding spray from 18-wheelers on Interstate 84 — sign me up. Autonomous technology will also take some of the stress, tedium and fatigue out of long highway drives, as I recently discovered while testing Cadillac Super Cruise. AVs are also supposed to eventually help increase traffic flow and reduce gridlock. But according to a recent Automotive News article, as the first wave of AVs are being tested on public roads, they're having the opposite effect. Part of the problem is they drive too cautiously and are programmed to strictly follow the written rules of the road rather than going with the flow of traffic. "Humans violate the rules in a safe and principled way, and the reality is that autonomous vehicles in the future may have to do the same thing if they don't want to be the source of bottlenecks," Karl Iagnemma, CEO of self-driving technology developer NuTonomy, told Automotive News. "You put a car on the road which may be driving by the letter of the law, but compared to the surrounding road users, it's acting very conservatively." I get it that, like teen drivers, AVs need a ramp up period to learn the unwritten rules of the road and that a skeptical public has to be convinced of the technology's safety. But this is where I become less of a champion on AVs, since where I live in the Pacific Northwest we already have more than our share of overly cautious human drivers. Since moving here 12 years ago, I've found it's an interesting paradox that a region famous for its strong coffee, where you'd think most drivers would be jacked up on caffeine, is also the home to annoyingly measured motorists. As an auto-journo colleague living in Seattle so aptly put it: "People in the Pacific Northwest drive as if they have nowhere to go." If you drive like me and always have somewhere to go — and usually are in a hurry to get there — it's absolutely maddening.
