Lucid Gravity Highway Range Test: 'Not Quite As Expected,' And Here's Why

• The Lucid Gravity SUV is rated to be a long-distance champion at 450 miles of EPA-rated range.
• But State of Charge's Tom Moloughney did the usual 70 mph run down to nearly empty, and achieved 345 miles at 3.0 miles per kilowatt-hour—not Lucid's usual landmark efficiency. 
• Tom got in touch with Lucid's engineers, and the carmaker says there may have been a problem with the SUV's rear drive unit.
