An automobile delivers 30 hp to its whells when moving at a constant speed of 22 m/s

Given the simple relationship between horsepower and acceleration, this would be equivalent to an automobile delivering 120 hp when slowly accelerating.

the way to calculate how much power goes through the drive train is to multiply the number of wheels by the engine's horsepower rating which will give you total horsepower distributed by engine size. for instance, 6-wheel drive 6×300=1800, 6×60=360 so for this case 1800/360=5. so in this example it might be thought that two engines are viable options provided they generate 900 or more hp each for six-wheel drive based on one application. furthermore, not only does every tire have a certain rolling radius but also contact area with roads decreases at higher speeds due to tires scrubbing
