Audi TT vs Chrysler 300: Specs Compared

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 $2,650 for the Chrysler 300. 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 Audi TT leads in both cycles — 23 mpg city and 31 mpg highway against 19 and 30 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 Chrysler 300 with 4 (3.6, 5.7, 6.4). Across 12 recorded Audi TT configurations and 38 for the Chrysler 300, 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 Chrysler 300 with All-Wheel Drive, 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 Large 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 Audi TT emits 340 g/mile of CO2 versus 389 g/mile for the Chrysler 300. Emissions track fuel consumption almost exactly, so the cleaner vehicle here is also the cheaper one to fuel.
