So Lucid developed a proprietary “boost” technology—it declined to springiness WIRED precise details—to rise incoming 500-volt powerfulness to lucifer the pack’s 926 volts. It says lone that it uses the rear centrifugal portion to bash so, presumably done 1 of the windings acting arsenic a DC-DC inverter. The boost relation delivers up to 225 kW from a v3 Supercharger.
Lucid besides moved the Gravity’s charge-port doorway from the left-front fender to the near rear, conscionable arsenic it is contiguous connected Tesla cars—allowing the Gravity to usage existent Tesla v3 Superchargers with their characteristically abbreviated cables. While 2 pre-production cars astatine the thrust lawsuit had some ports, immoderate Gravity you tin bargain comes with a NACS connector—along with a CCS-NACS adapter. And, laudably, the institution worked with Tesla to bash the bundle integration that allows due Plug and Charge astatine Tesla chargers: plug successful the car, locomotion away, and each the authentication and billing is done connected the backmost 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, alternatively than lone recharging them periodically. That greatly extends the beingness of immoderate 12-volt battery, a century-old exertion not designed for regular heavy discharges earlier recharging. Why 2 12V batteries? For redundancy, truthful it tin parkland safely astatine the broadside of the roadworthy adjacent if 1 artillery is damaged successful a crash.
Lucid says the Gravity’s sensor suite—12 exterior and 2 interior cameras, 5 radars, 1 lidar, and 12 ultrasonic sensors— volition “enable Level 3 autonomy,” it’s inactive rolling retired definite of its premium ADAS features via over-the-air updates. The afloat diagnostic acceptable of DreamDrive 2 Pro is planned for a autumn delivery; that includes not lone hands-free enhanced cruise control, but besides the unsocial “Curb Rash Alert” to dependable an alarm if a operator is successful information of scraping a instrumentality connected a curb.
Not a Butch SUV, but What Is It?
EV plan sometimes takes vantage of the packaging opportunities, with a abbreviated beveled chemoreceptor and a longer compartment (see the Tesla Model 3, Jaguar I-Pace). Other makers (like BMW) shy distant from thing that suggests their EVs aren’t “regular” cars, meaning proportions that could location a combustion motor up front. Lucid sits firmly successful the archetypal camp. The rear doors are huge, entree to the 3rd enactment is arsenic casual arsenic immoderate conveyance we’ve tested, and a 6’6” workfellow was capable to ascent into that 3rd enactment and beryllium with immoderate semblance of comfort.

It’s each astir the drag, oregon much precisely, lessening it to each past imaginable grade to wring greater scope retired of a fixed artillery capacity. Lucid quotes a resistance coefficient of 0.24, singular for a conveyance this large—though Cd figures from antithetic makers can’t beryllium compared owed to varying methods of measurement. Combined with a remarkably airy value of conscionable 6,000 pounds (thanks to aluminum construction), the slippery plan produces an ratio of up to 3.6 miles/kWh (450 miles from a 123-kWh pack). It varies with instrumentality size (smaller is better) and rider configuration (5 seats is amended than 7).
Drives Smaller Than It Is
Our vehicle, the 7-seat exemplary with 20- and 21-inch wheels (front and rear), showed conscionable 2.22 miles/kWh aft an energetic thrust done the foothills of Los Olivos, California. But our driving was hardly emblematic of the affluent suburbanite-family duties the Gravity volition astir apt see.
We did immoderate acceleration runs, took it concisely to extra-legal speeds connected limited-access highways, and cycled regularly among the 3 thrust modes: Smooth (normal), Swift (sport), and Sprint (fastest). Smooth gave a somewhat engaged ride, portion Swift felt much controlled and precise. Sprint was the astir “German” of the three. We mostly toggled betwixt the past two, but the differences among them were much subtle and overmuch little pronounced than successful different EVs WIRED has driven.
