BMW 4 Series vs Chevrolet Malibu: Specs Compared

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Chevrolet Malibu burns about $1,350 of fuel annually against $2,450 for the BMW 4 Series. That $1,100 yearly gap compounds to roughly $5,500 over five years and $8,800 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 Chevrolet Malibu leads in both cycles — 49 mpg city and 46 mpg highway against 28 and 36 mpg — so its fuel-efficiency advantage holds whether you commute in traffic or cover long highway miles.

Powertrain choice: the BMW 4 Series is recorded with 4 distinct engine configurations (SIDI & PFI; Mild Hybrid, SIDI, SIDI; Mild Hybrid), the Chevrolet Malibu with 2 (SIDI, SIDI; Hybrid). Across 160 recorded BMW 4 Series configurations and 24 for the Chevrolet Malibu, 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 4 Series is offered with Rear-Wheel Drive, All-Wheel Drive, the Chevrolet Malibu 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.

Tailpipe emissions: at their cleanest configurations the Chevrolet Malibu emits 194 g/mile of CO2 versus 285 g/mile for the BMW 4 Series. Emissions track fuel consumption almost exactly, so the cleaner vehicle here is also the cheaper one to fuel.
