Rivian R1S vs Volvo EX90: what the numbers mean
Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Volvo EX90 burns about $800 of fuel annually against $900 for the Rivian R1S. 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 Volvo EX90 leads in both cycles — 104 mpg city and 91 mpg highway against 94 and 77 mpg — so its fuel-efficiency advantage holds whether you commute in traffic or cover long highway miles.
Drivetrain and class: the Rivian R1S is offered with 4-Wheel Drive, Part-time 4-Wheel Drive, All-Wheel Drive, the Volvo EX90 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 Standard Sport Utility Vehicle 4WD and Standard Sport Utility Vehicle 4WD respectively — the class drives the interior volume, cargo space and passenger space each one is measured against.
