One of the world’s poster children for conspicuous consumption will get an EV variant for 2023. The Escalade-sized EV will be based on that other gross polluter–turned–green machine, the forthcoming Hummer EV by GMC. The full-size electric SUV might also get the same superlative 1,000 horsepower as the Hummer, and it will be built using GM’s Ultium battery technology and modular electric vehicle platform.
