Hyundai Sonata vs Jaguar XF: Specs Compared

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Hyundai Sonata burns about $1,200 of fuel annually against $2,300 for the Jaguar XF. 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 Hyundai Sonata leads in both cycles — 50 mpg city and 56 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 Hyundai Sonata is recorded with 4 distinct engine configurations (SIDI; Hybrid, SIDI & PFI, SIDI & PFI; with Stop-Start), the Jaguar XF with 3 (SIDI, 2.0, SIDI; FFV). Across 81 recorded Hyundai Sonata configurations and 45 for the Jaguar XF, 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 Hyundai Sonata is offered with Front-Wheel Drive, All-Wheel Drive, the Jaguar XF with Rear-Wheel Drive, All-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 Large 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 Hyundai Sonata emits 100 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.
