Making its North American debut at the 1997 Chicago show was the Mercedes-Benz F200 coupe concept. The F200 used a ‘revolutionary drive-by-wire’ technology that eliminated the steering wheels and pedals. Instead, the vehicle was controlled via ergonomically designed, aircraft-style joysticks in the central console and door recess. The most notable exterior feature were the hydraulically operated doors which opened up and forward with a scissors-like movement. This unusual design made for easier entrance and exit of the vehicle, required less space for parking, and allowed the door openings to be some six inches wider than usual.
