Lamborghini Huracan vs Mercedes-Benz SL-Class: Specs Compared

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Mercedes-Benz SL-Class burns about $3,300 of fuel annually against $4,450 for the Lamborghini Huracan. 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 Mercedes-Benz SL-Class leads in both cycles — 21 mpg city and 28 mpg highway against 14 and 21 mpg — so its fuel-efficiency advantage holds whether you commute in traffic or cover long highway miles.

Powertrain choice: the Lamborghini Huracan is recorded with 1 distinct engine configuration (SIDI & PFI), the Mercedes-Benz SL-Class with 4 (SIDI, SIDI; Mild Hybrid, SIDI; PHEV). Across 34 recorded Lamborghini Huracan configurations and 40 for the Mercedes-Benz SL-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 Lamborghini Huracan is offered with All-Wheel Drive, Rear-Wheel Drive, the Mercedes-Benz SL-Class with All-Wheel Drive, Rear-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 Two Seaters and Two Seaters 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 SL-Class emits 379 g/mile of CO2 versus 532 g/mile for the Lamborghini Huracan. Emissions track fuel consumption almost exactly, so the cleaner vehicle here is also the cheaper one to fuel.
