Acura TLX vs Toyota GR 86: Specs Compared

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Acura TLX burns about $2,700 of fuel annually against $3,050 for the Toyota GR 86. That $350 yearly gap compounds to roughly $1,750 over five years and $2,800 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 Acura TLX leads in both cycles — 24 mpg city and 35 mpg highway against 21 and 31 mpg — so its fuel-efficiency advantage holds whether you commute in traffic or cover long highway miles.

Powertrain choice: the Acura TLX is recorded with 1 distinct engine configuration (SIDI), the Toyota GR 86 with 1 (SIDI & PFI). Across 50 recorded Acura TLX configurations and 8 for the Toyota GR 86, 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 Acura TLX is offered with Front-Wheel Drive, All-Wheel Drive, the Toyota GR 86 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 Compact 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 Acura TLX emits 321 g/mile of CO2 versus 360 g/mile for the Toyota GR 86. Emissions track fuel consumption almost exactly, so the cleaner vehicle here is also the cheaper one to fuel.
