ACCELERATION FT/SEC.² SURMOUNTABLE GRADIENT Torque curve, car weight, displacement. As hill climbing is so closely related to acceleration it is affected in exactly the same manner by car weight, displacement, the torque curve etc. The remarks made under the heading of Acceleration on these subjects therefore apply in this case. A normal car would gain practically nothing in speed and lose accelerating capabilities. contd :- | ||
