Infiniti Q50 vs Nissan Versa: Specs Compared

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Nissan Versa burns about $1,750 of fuel annually against $2,450 for the Infiniti Q50. 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 Nissan Versa leads in both cycles — 32 mpg city and 40 mpg highway against 29 and 36 mpg — so its fuel-efficiency advantage holds whether you commute in traffic or cover long highway miles.

Powertrain choice: the Infiniti Q50 is recorded with 4 distinct engine configurations (SIDI, 3.5, 2.0), the Nissan Versa with 1 (1.6). Across 60 recorded Infiniti Q50 configurations and 26 for the Nissan Versa, 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 Infiniti Q50 is offered with All-Wheel Drive, Rear-Wheel Drive, the Nissan Versa with 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 Midsize Cars and Compact Cars respectively — the class drives the interior volume, cargo space and passenger space each one is measured against.

Tailpipe emissions: at their cleanest configurations the Nissan Versa emits 253 g/mile of CO2 versus 286 g/mile for the Infiniti Q50. Emissions track fuel consumption almost exactly, so the cleaner vehicle here is also the cheaper one to fuel.
