104 SMT007 MAGAZINE I FEBRUARY 2021 trucks, SUVs, and off-road. e EV batter- ies (Figure 1) are specifically designed for storage and are arranged in modules, and grouped into eight-, 12-, and 20-module frames. ere are five drive trains to choose from for front-, rear-, or all-wheel propul- sion (Figure 2). is will provide 450 miles between charging. ey will be controlled from a single digital soware architecture (vehicle intelligence platform) capable of processing 4.5 terabytes of information per second. is is five times more than their current offerings. Current battery research to eliminate rare nickel and cobalt metals is expected to raise this mileage to 500 to 600 miles between charging. e first Ultium product is the new 2021 Hummer EV (Figure 3). As ridiculous at it sounds, the Ultium package for the Hum- mer is rated at 1000 horsepower and capa- ble of 0 to 60 mph in three seconds! To get this kind of performance, you must enter a code, then the Hummer reconfigures the batteries, lowers the chassis, builds up an energy storage, secures your flight har- ness, checks the available road, and awaits your launch command—all with associated sound effects. Normal driving and off-road all have different battery and chassis con- figurations that are pre-defined. At the other end of vehicle design is the new Cadillac Lyriq EV crossover (Figure 4) Figure 2: GM's next-generation EVs are expected to be powered by a family of five interchangeable drive units and three drive assist motors known collectively as "Ultium Drive."
