Your eyes may glaze over at the mention of a car's "platform," but carmakers lose sleep trying to come up with one that supports the kind of car you'll like. So pay attention.
Watch this: How skateboards are inspiring electric cars
"Platform" refers to what we commonly, and somewhat erroneously, call the chassis of a car: The belly pan, suspension, mounting points for engine, transmission, doors, gas tank and more. It's the most expensive, complicated thing an automaker does so they try to base as many cars as possible on as few platforms as they can. For example, the current
all share a platform, even though they're very different vehicles.
But electric vehicles from
, Rivian, Byton and Faraday, as well as those from stalwarts like GM, use a new kind of platform referred to as a "skateboard," generally defined by these traits:
A low flat battery that is the structural belly of the car. It can be lengthened or shortened pretty easily for different models while creating few intrusions into the floor of the vehicle.
Compact motors at the ends or corners of the skateboard get out of the way compared to the cumbersome engine, transmission and driveline of most combustion engine cars.
Drive-by-wire accelerator, brakes, drive control and even steering removes the hard mounting points and intrusions for all those controls.
Any number of bodies can then be easily designed to ride atop the skateboard since it dictates less of their specifics. This gives a carmaker greater efficiency by reducing assembly line complexity while gaining nimbleness as consumer tastes change.
The skateboard platform may sound like an innovation from the auto industry's recent swing toward Silicon Valley but, in fact, it's generally credited to GM's Autonomy concept car of 2002. That vehicle imagined a skateboard as a way to take advantage of hydrogen fuel cell drivetrain technology. The hydrogen part is still a work in progress but, 18 years later, the idea of a skateboard has proved a prescient one.
