Lexus ES vs Mercedes-Benz EQS: Specs Compared

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Lexus ES burns about $600 of fuel annually against $700 for the Mercedes-Benz EQS. That $100 yearly gap compounds to roughly $500 over five years and $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 Lexus ES leads in both cycles — 135 mpg city and 118 mpg highway against 101 and 105 mpg — so its fuel-efficiency advantage holds whether you commute in traffic or cover long highway miles.

Powertrain choice: the Lexus ES is recorded with 4 distinct engine configurations (SIDI & PFI; Hybrid, SIDI & PFI, 2.5), the Mercedes-Benz EQS with no. Across 40 recorded Lexus ES configurations and 32 for the Mercedes-Benz EQS, 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 Lexus ES is offered with Front-Wheel Drive, All-Wheel Drive, the Mercedes-Benz EQS 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 Midsize Cars and Large Cars respectively — the class drives the interior volume, cargo space and passenger space each one is measured against.
