Drivetrain and class: the Hyundai Ioniq 6 is offered with All-Wheel Drive, Rear-Wheel Drive, the Tesla Model 3 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 Midsize Cars respectively — the class drives the interior volume, cargo space and passenger space each one is measured against.
