Last week I asked what car driver’s manual advised drivers to take off in top gear as there was too much torque in the lower ratios for him to handle? It was Invicta and the advice was in the drivers manual for the four and a half liter Low Chassis Black Prince.
So to this week. By 1931 various US manufacturer’s, including Chrysler, Dodge, Desoto, Dodge, Franklin, Graham, Plymouth, Reo and Graham produced cars with an advanced system. Still used today – what was it?
