Subaru Legacy vs Volkswagen Jetta: Specs Compared

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Volkswagen Jetta burns about $1,750 of fuel annually against $2,050 for the Subaru Legacy. That $300 yearly gap compounds to roughly $1,500 over five years and $2,400 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 Volkswagen Jetta leads in both cycles — 42 mpg city and 48 mpg highway against 27 and 35 mpg — so its fuel-efficiency advantage holds whether you commute in traffic or cover long highway miles.

Powertrain choice: the Subaru Legacy is recorded with 3 distinct engine configurations (SIDI, 2.5, 3.6), the Volkswagen Jetta with 3 (SIDI;, SIDI, 2.0). Across 16 recorded Subaru Legacy configurations and 51 for the Volkswagen Jetta, 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 Subaru Legacy is offered with All-Wheel Drive, the Volkswagen Jetta 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 Midsize Cars and Compact 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 Volkswagen Jetta emits 200 g/mile of CO2 versus 295 g/mile for the Subaru Legacy. Emissions track fuel consumption almost exactly, so the cleaner vehicle here is also the cheaper one to fuel.
