Cadillac OPTIQ vs Lucid Gravity: what the numbers mean
Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Cadillac OPTIQ burns about $700 of fuel annually against $700 for the Lucid Gravity. That $0 yearly gap compounds to roughly $0 over five years and $0 over eight — often more than the price difference between two trims of the same vehicle, and the single largest running-cost line item separating these two.
City versus highway split: the Cadillac OPTIQ is the stronger commuter at 117 mpg city, while the Lucid Gravity pulls ahead on the interstate at 106 mpg highway. If most of your driving is stop-and-go traffic the city figure is the one to weigh; for long-distance highway mileage the reverse is true, and the two vehicles effectively swap places depending on how you drive.
Drivetrain and class: the Cadillac OPTIQ is offered with Rear-Wheel Drive, All-Wheel Drive, the Lucid Gravity with All-Wheel Drive. All-wheel drive typically costs one to two mpg combined against the same vehicle in front- or rear-wheel drive, which is worth remembering when the gap between these two is small. The EPA classes them as Standard Sport Utility Vehicle 2WD and Standard Sport Utility Vehicle 4WD respectively — the class drives the interior volume, cargo space and passenger space each one is measured against.
