Lexus RC vs Nissan Sentra: Specs Compared

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Nissan Sentra burns about $1,800 of fuel annually against $2,900 for the Lexus RC. That $1,100 yearly gap compounds to roughly $5,500 over five years and $8,800 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 Nissan Sentra leads in both cycles — 30 mpg city and 40 mpg highway against 22 and 32 mpg — so its fuel-efficiency advantage holds whether you commute in traffic or cover long highway miles.

Powertrain choice: the Lexus RC is recorded with 1 distinct engine configuration (SIDI & PFI), the Nissan Sentra with 2 (SIDI, 1.8). Across 50 recorded Lexus RC configurations and 38 for the Nissan Sentra, 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 RC is offered with All-Wheel Drive, Rear-Wheel Drive, the Nissan Sentra 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 Subcompact Cars and Midsize 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 Nissan Sentra emits 262 g/mile of CO2 versus 345 g/mile for the Lexus RC. Emissions track fuel consumption almost exactly, so the cleaner vehicle here is also the cheaper one to fuel.
