Jaguar XF vs Toyota Prius Prime: Specs Compared

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Toyota Prius Prime burns about $1,150 of fuel annually against $2,300 for the Jaguar XF. That $1,150 yearly gap compounds to roughly $5,750 over five years and $9,200 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 Prius Prime leads in both cycles — 55 mpg city and 53 mpg highway against 31 and 42 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 Toyota Prius Prime with 2 (SIDI & PFI; PHEV, PHEV). Across 45 recorded Jaguar XF configurations and 10 for the Toyota Prius Prime, 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 Toyota Prius Prime 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 Toyota Prius Prime emits 50 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.
