Dear Sir,That's 2.47 N/kg or meters/second squared, which is 5.52 mph/second, or a bit under 11 seconds 0 to 60 mph - if you maintain that value of torque, which of course is not constant over the entire rpm range for either an ICE or electric motor/controller. The torque falls off at higher rpm for the electric motor/controller, that be the problem.
but isnt this equation bit deceptive. It depicts that if one increases the wheel torque to a very large number by using high motor torque and gear ratio, the acceleration would be enormous. Practically such a high acc would cause tyres to skid. Is there way to calculate max allowable acceleration considering the point after which the tyre skids?
