| contd:- -3- When comparing this car with the standard 40/50 HP. on narrow roads and hill climbing, the difference in gear ratio must be born in mind. The standard 40/50 car has been 14/52 compared with 16/52 on the EAC.11. A lower geared axle fitted to this car would give a very much better impression of power under average running conditions.
