BMW 2 Series vs Subaru BRZ: Specs Compared

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the BMW 2 Series burns about $2,450 of fuel annually against $2,700 for the Subaru BRZ. That $250 yearly gap compounds to roughly $1,250 over five years and $2,000 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 BMW 2 Series leads in both cycles — 27 mpg city and 39 mpg highway against 24 and 33 mpg — so its fuel-efficiency advantage holds whether you commute in traffic or cover long highway miles.

Powertrain choice: the BMW 2 Series is recorded with 3 distinct engine configurations (SIDI & PFI; Mild Hybrid, SIDI, SIDI & PFI), the Subaru BRZ with 1 (SIDI & PFI). Across 93 recorded BMW 2 Series configurations and 26 for the Subaru BRZ, 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 BMW 2 Series is offered with Rear-Wheel Drive, All-Wheel Drive, Front-Wheel Drive, the Subaru BRZ with Rear-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 Minicompact 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 BMW 2 Series emits 279 g/mile of CO2 versus 321 g/mile for the Subaru BRZ. Emissions track fuel consumption almost exactly, so the cleaner vehicle here is also the cheaper one to fuel.
