it's light weight, and that affects accel, but or top speed, u
need a lot more power.
A car's max speed depends on 3 things:
Max power output.
Its tyre rolling resistance
Aerodynamic drag
This is assuming that it is geared so that peak power in top gear
coincides with the max speed, otherwise there is a small
penalty.
in turn, tre rolling resistance(TRR) depends on the resisitance
coefficient, the weight of the car, and to a limited extent on
speed. aerodynamic drag depends on the frontal area of the car, its
drag coefficient(Cd), and the square of the speed.
At very high speeds, aero drag is so much higher than the TRR that
TRR can be disregarded.
it would be simpler to calculate a car's max speed with known
figures than to do it from scratch, because u need knowledge of the
car's frontal area n CD, plus its power output.
Anyways, what is the max power of the hyundai Getz? i can do a
simple calculation of how much u have to increase the bhp if u want
a higher top speed.
