Audi TT vs Lexus LC: what the numbers mean

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Audi TT burns about $2,350 of fuel annually against $2,550 for the Lexus LC. That $200 yearly gap compounds to roughly $1,000 over five years and $1,600 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 Lexus LC leads in both cycles — 27 mpg city and 35 mpg highway against 23 and 31 mpg — so its fuel-efficiency advantage holds whether you commute in traffic or cover long highway miles.

Powertrain choice: the Audi TT is recorded with 1 distinct engine configuration (SIDI), the Lexus LC with 2 (SIDI & PFI, SIDI & PFI; Hybrid). Across 12 recorded Audi TT configurations and 23 for the Lexus LC, 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 Audi TT is offered with All-Wheel Drive, the Lexus LC 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 Subcompact 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 Lexus LC emits 298 g/mile of CO2 versus 340 g/mile for the Audi TT. Emissions track fuel consumption almost exactly, so the cleaner vehicle here is also the cheaper one to fuel.
