Toyota bZ4X vs Volkswagen ID.4: 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 $650 for the Volkswagen ID.4. That $0 yearly gap compounds to roughly $0 over five years and $0 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 122 and 104 mpg — so its fuel-efficiency advantage holds whether you commute in traffic or cover long highway miles.
Drivetrain and class: the Toyota bZ4X is offered with Front-Wheel Drive, All-Wheel Drive, the Volkswagen ID.4 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 Small Sport Utility Vehicle 4WD and Small Sport Utility Vehicle 2WD respectively — the class drives the interior volume, cargo space and passenger space each one is measured against.
