BMW i5 vs Nissan LEAF: what the numbers mean

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the BMW i5 burns about $650 of fuel annually against $650 for the Nissan LEAF. That $0 yearly gap compounds to roughly $0 over five years and $0 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 versus highway split: the Nissan LEAF is the stronger commuter at 131 mpg city, while the BMW i5 pulls ahead on the interstate at 113 mpg highway. If most of your driving is stop-and-go traffic the city figure is the one to weigh; for long-distance highway mileage the reverse is true, and the two vehicles effectively swap places depending on how you drive.

Drivetrain and class: the BMW i5 is offered with All-Wheel Drive, Rear-Wheel Drive, 4-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 Compact Cars and Midsize Cars respectively — the class drives the interior volume, cargo space and passenger space each one is measured against.
