Infiniti Q50 vs Toyota Crown: Specs Compared

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Toyota Crown burns about $1,500 of fuel annually against $2,450 for the Infiniti Q50. That $950 yearly gap compounds to roughly $4,750 over five years and $7,600 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 Toyota Crown leads in both cycles — 42 mpg city and 41 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 Toyota Crown with 1 (SIDI & PFI; Hybrid). Across 60 recorded Infiniti Q50 configurations and 8 for the Toyota Crown, 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 Toyota Crown 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 Midsize Cars and Midsize 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 Toyota Crown emits 214 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.
