What's the top speed on your car?

If you are saying that weight does not effect the top speed of a car then. You should be able to take your theory to the extremes and it would still hold true.

Once I overloaded the back of the work truck with cement a (96 F-350 1 ton with a 460) the truck would barely move and when it did get going it would not exceed 65 MPH. The cement did not affect the aerodynamics so was it not the weight that slowed the trucks top speed.

If weight is not a factor then why do cars and trucks have a tow rating. According to your theory if you can get the load to move then you can take it all the way up to your vehicles top speed taking the wind drag of the trailor into account of course.

So you are saying that if a car is topped out at 150 MPH and all of the sudden you throw an extra 2000 lbs of weight in the car that it will slow down but will eventually regain its speed of 150 MPH.

If you are saying that weight does not effect top speed but does effect acceleration
then (Force = Mass * Acceleration) it appears to me that if I could effect the acceleration of a car with weight then I would also effect the force or speed since force is a buy product of mass times acceleration....
