So Lucid developed a proprietary “boost” technology—it declined to give WIRED precise details—to raise incoming 500-volt power to match the pack’s 926 volts. It says only that it uses the rear motor unit to do so, presumably through one of the windings acting as a DC-DC inverter. The boost function delivers up to 225 kW from a v3 Supercharger.

Lucid also moved the Gravity’s charge-port door from the left-front fender to the left rear, just as it is today on Tesla cars—allowing the Gravity to use current Tesla v3 Superchargers with their characteristically short cables. While two pre-production cars at the drive event had both ports, any Gravity you can buy comes with a NACS connector—along with a CCS-NACS adapter. And, laudably, the company worked with Tesla to do the software integration that allows proper Plug and Charge at Tesla chargers: plug in the car, walk away, and all the authentication and billing is done on the back end, automatically.

Keeping 12-Volt Batteries Healthy

Another electrical trick: the Gravity uses a “Micro DC-DC converter” to trickle-charge the Gravity’s 12-volt batteries from the traction battery, rather than only recharging them periodically. That greatly extends the life of any 12-volt battery, a century-old technology not designed for regular deep discharges before recharging. Why two 12V batteries? For redundancy, so it can park safely at the side of the road even if one battery is damaged in a crash.

Lucid says the Gravity’s sensor suite—12 exterior and two interior cameras, 5 radars, one lidar, and 12 ultrasonic sensors— will “enable Level 3 autonomy,” it’s still rolling out certain of its premium ADAS features via over-the-air updates. The full feature set of DreamDrive 2 Pro is planned for a fall delivery; that includes not only hands-free enhanced cruise control, but also the unique “Curb Rash Alert” to sound an alarm if a driver is in danger of scraping a wheel on a curb.

Not a Butch SUV, but What Is It?

EV design sometimes takes advantage of the packaging opportunities, with a short beveled nose and a longer cabin (see the Tesla Model 3, Jaguar I-Pace). Other makers (like BMW) shy away from anything that suggests their EVs aren’t “regular” cars, meaning proportions tha...
