Inside Batmobile ...
In about 1973, Corgi produced a Batmobile with hard plastic tyres. These were actually whizzwheels on a thin, flexible axle so the car would roll very freely. Unfortunately, this meant the pulsating exhaust flame was eliminated. Also, the spacing of the axle posts was closer together to accommodate the thinner axle and the molding for the plastic seats and suspension changed to account for the thinner axles (first picture) and non-pulsating exhaust flame (but these latter two changes are not visible from an external perspective).
On the second picture, see broken front suspensions.
