Jaguar XF 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 $2,300 for the Jaguar XF. That $500 yearly gap compounds to roughly $2,500 over five years and $4,000 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 Jaguar XF leads in both cycles — 31 mpg city and 42 mpg highway against 30 and 40 mpg — so its fuel-efficiency advantage holds whether you commute in traffic or cover long highway miles.

Powertrain choice: the Jaguar XF is recorded with 3 distinct engine configurations (SIDI, 2.0, SIDI; FFV), the Nissan Sentra with 2 (SIDI, 1.8). Across 45 recorded Jaguar XF 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 Jaguar XF is offered with Rear-Wheel Drive, All-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 Midsize 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 289 g/mile for the Jaguar XF. Emissions track fuel consumption almost exactly, so the cleaner vehicle here is also the cheaper one to fuel.
