Lucid Air vs Mercedes-Benz CLA-Class: what the numbers mean

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Lucid Air burns about $500 of fuel annually against $600 for the Mercedes-Benz CLA-Class. That $100 yearly gap compounds to roughly $500 over five years and $800 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 and highway economy: the Lucid Air leads in both cycles — 149 mpg city and 142 mpg highway against 127 and 124 mpg — so its fuel-efficiency advantage holds whether you commute in traffic or cover long highway miles.

Powertrain choice: the Lucid Air is recorded with no distinct engine configurations, the Mercedes-Benz CLA-Class with 3 (SIDI; Mild Hybrid, SIDI, SIDI; FFV). Across 41 recorded Lucid Air configurations and 55 for the Mercedes-Benz CLA-Class, the wider the engine spread the more the real-world fuel efficiency depends on which version you actually buy, so check the specific model year and drivetrain rather than the headline number.

Drivetrain and class: the Lucid Air is offered with All-Wheel Drive, Rear-Wheel Drive, the Mercedes-Benz CLA-Class with All-Wheel Drive, Rear-Wheel Drive, Front-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 Large Cars and Compact Cars respectively — the class drives the interior volume, cargo space and passenger space each one is measured against.
