The F 100 research car caused quite a stir at the 1991 North American International Motor Show in Detroit. With this particular study, Daimler Chrysler hoped to inspire numerous aspects of future passenger car development without losing sight in any way of the top-priority concerns of safety and comfort.
With the combined expertise of MBB, AEG-Telefunken, and Dornier - all Daimler subsidiaries at that time - the research engineers of Mercedes-Benz succeeded in devising a car that was brimming with ingenious new ideas and design touches. For example, taking the interior, the driver was not seated on one side as in conventional cars. Instead, the driver"s seat was placed in the safest position of all: in the middle. The idea for this novel seating arrangement stemmed from the finding that only 1.5 people are traveling in each passenger car on average. This statistical revelation led researchers to conclude that the car's safest place should be reserved for the driver.
Spreading out before the driver was a cockpit that featured a color monitor instead of an instrument cluster. As well as showing readings for road speed and engine speed, the monitor could also issue warnings when the tire pressure was too low, the oil needed to be topped up, or there was insufficient washer fluid in the reservoir, for example.
The F 100 could carry five people in all, with two rows of seats in the saloon's rear offering ample space for four passengers. A clever new door concept was developed for convenient access and egress: special hinged pivoting doors were devised for the front, which used an elaborate hinged mechanism combined with two servo units to swing the door up away from the floor. At the rear of the car could be found pivot-and-slide doors, whose light operating mechanism was controlled by an electrically powered servo system similarly to the front doors. This servo function can be found today in various models from Mercedes-Benz.
The electrical energy required to operate this modern-day "Open Sesame!" door opener was drawn from solar collectors mounted on the roof of the F 100. Covering an area of two square meters, this solar "sail" could generate 100 watts of power continuously fed into the vehicle"s electrical system, paving the way for the inclusion of further features. If the car were left parked with the summer sun beating down on it, for instance, the electronics would use the solar power to actuate a mini blower, which would then expel the hot air built up inside the car into the atmosphere. Since 2002, this very same function has been offered as a convenience feature for the Mercedes-Benz E-Class.
Once safely seated inside the car, the driver could concentrate on the task at hand. There was no need to preoccupy himself with adjusting the seat and mirrors to the correct position. That was all taken care of by a small magnetic smart card, a data-carrying device that doubled as the vehicle"s ignition key. The magnetic stripe on the plastic card stored personalized driver data, which was used by the onboard computer to adjust both seat and mirrors into the correct position with the assistance of servo motors. Some years later, the F 200 Imagination appeared featuring a refined version of the smart card system, which went on to celebrate its series production premiere in the Mercedes-Benz S-Class in 1998.
