Jaguar XF vs Mercedes-Benz E-Class: Specs Compared

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Jaguar XF burns about $2,300 of fuel annually against $2,700 for the Mercedes-Benz E-Class. That $400 yearly gap compounds to roughly $2,000 over five years and $3,200 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 Jaguar XF leads in both cycles — 31 mpg city and 42 mpg highway against 25 and 33 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 Mercedes-Benz E-Class with 4 (SIDI; Mild Hybrid, SIDI; PHEV, SIDI). Across 45 recorded Jaguar XF configurations and 136 for the Mercedes-Benz E-Class, 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 Mercedes-Benz E-Class with All-Wheel Drive, Rear-Wheel Drive, 4-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 Mercedes-Benz E-Class emits 115 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.
