Genesis GV80 vs Mercedes-Benz GLA-Class: Specs Compared

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Mercedes-Benz GLA-Class burns about $2,600 of fuel annually against $3,300 for the Genesis GV80. That $700 yearly gap compounds to roughly $3,500 over five years and $5,600 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 Mercedes-Benz GLA-Class leads in both cycles — 26 mpg city and 34 mpg highway against 21 and 26 mpg — so its fuel-efficiency advantage holds whether you commute in traffic or cover long highway miles.

Powertrain choice: the Genesis GV80 is recorded with 2 distinct engine configurations (SIDI & PFI; Mild Hybrid, SIDI & PFI), the Mercedes-Benz GLA-Class with 3 (SIDI; Mild Hybrid, SIDI, SIDI; FFV). Across 21 recorded Genesis GV80 configurations and 43 for the Mercedes-Benz GLA-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 Genesis GV80 is offered with All-Wheel Drive, Rear-Wheel Drive, the Mercedes-Benz GLA-Class with All-Wheel Drive, Front-Wheel Drive, 4-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 4WD and Small Sport Utility Vehicle 4WD respectively — the class drives the interior volume, cargo space and passenger space each one is measured against.

Tailpipe emissions: at their cleanest configurations the Mercedes-Benz GLA-Class emits 306 g/mile of CO2 versus 394 g/mile for the Genesis GV80. Emissions track fuel consumption almost exactly, so the cleaner vehicle here is also the cheaper one to fuel.
