The size of a Formula One car’s cockpit opening must
comply with strict specifications. Compliance with these specifications
is tested by lowering a specially made template into the cockpit.
addition to this, the cockpit must meet numerous other requirements. A
driver must be able to get in and out of the car without removing
anything other than its steering wheel. Once strapped into the car with
all his safety gear on, he must be able to remove the steering wheel and
get out within five seconds, and then replace the steering within a
further five seconds.
The car’s survival cell structure, designed
to protect the driver in the event of an accident, must extend at least
300mm beyond the drivers feet, which must not be forward of the
front-wheel centre line.
