Audi e-tron S vs Toyota bZ4X: what the numbers mean
Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Toyota bZ4X burns about $650 of fuel annually against $1,000 for the Audi e-tron S. That $350 yearly gap compounds to roughly $1,750 over five years and $2,800 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 Toyota bZ4X leads in both cycles — 131 mpg city and 107 mpg highway against 73 and 78 mpg — so its fuel-efficiency advantage holds whether you commute in traffic or cover long highway miles.
Drivetrain and class: the Audi e-tron S is offered with All-Wheel Drive, the Toyota bZ4X with Front-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 Standard Sport Utility Vehicle 4WD and Small Sport Utility Vehicle 4WD respectively — the class drives the interior volume, cargo space and passenger space each one is measured against.
