MINI Cooper vs Nissan LEAF: what the numbers mean

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Nissan LEAF burns about $650 of fuel annually against $700 for the MINI Cooper. That $50 yearly gap compounds to roughly $250 over five years and $400 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 LEAF leads in both cycles — 131 mpg city and 111 mpg highway against 119 and 100 mpg — so its fuel-efficiency advantage holds whether you commute in traffic or cover long highway miles.

Powertrain choice: the MINI Cooper is recorded with 3 distinct engine configurations (SIDI & PFI, SIDI, 1.6), the Nissan LEAF with no. Across 135 recorded MINI Cooper configurations and 26 for the Nissan LEAF, 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 MINI Cooper is offered with Front-Wheel Drive, the Nissan LEAF 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 Subcompact Cars and Midsize Cars respectively — the class drives the interior volume, cargo space and passenger space each one is measured against.

Cooper vs LEAF: common questions

Which is better on gas, the MINI Cooper or the Nissan LEAF?

The Nissan LEAF is the more efficient of the two: it reaches 121 mpg combined versus 110 mpg for the MINI Cooper, a 11 mpg advantage and costs about $50 less per year to fuel.

Which costs less to run per year?

By EPA estimates at 15,000 miles a year, the Nissan LEAF runs about $650 a year in fuel at its most efficient configuration, versus about $700 for the MINI Cooper — a difference of roughly $50 per year.

What engines do the Cooper and LEAF offer?

MINI Cooper: SIDI & PFI, SIDI, 1.6. Nissan LEAF: no engine data on record.

Are they in the same vehicle class?

The EPA classifies the MINI Cooper as Subcompact Cars and the Nissan LEAF as Midsize Cars, so they aren't a like-for-like match on size.
