Lexus UX vs Toyota Corolla: Specs Compared

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Toyota Corolla burns about $1,200 of fuel annually against $1,450 for the Lexus UX. 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 Toyota Corolla leads in both cycles — 53 mpg city and 52 mpg highway against 45 and 41 mpg — so its fuel-efficiency advantage holds whether you commute in traffic or cover long highway miles.

Powertrain choice: the Lexus UX is recorded with 3 distinct engine configurations (SIDI & PFI; Hybrid, SIDI & PFI; Mild Hybrid, SIDI & PFI), the Toyota Corolla with 4 (SIDI & PFI, Hybrid, SIDI & PFI; 1-mode). Across 24 recorded Lexus UX configurations and 112 for the Toyota Corolla, 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 Lexus UX is offered with All-Wheel Drive, Front-Wheel Drive, the Toyota Corolla with Front-Wheel Drive, All-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 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 Toyota Corolla emits 170 g/mile of CO2 versus 204 g/mile for the Lexus UX. Emissions track fuel consumption almost exactly, so the cleaner vehicle here is also the cheaper one to fuel.
