Yes top speed is a pretty much a formula that that has frontal area (drag) and square of velocity. Weight/mass only comes in during acceleration. Hence, a car with a lower weight, all else equal, will get to it's top speed quicker, but it's top speed will not be higher than the car with more weight.

As an aside, most times when people say that they want high horsepower cars, they actually want high torque as hp is for pure top speed and torque is for acceleration.

 

Yup. once acceleration = 0 (aka, top speed) mass no longer effects things. Now, a heavier vehicle might have more friction in the bearings and more drag from the tires and the ground.. but its minimal.

 

Thanks for that information. I appreciate it. It's a bit counterintuitive, but it makes sense once you talk it through.

 

one click on the handbrake applies to all tip cars...and make them rwd...

 

anybody try the handbrake trick on 6sp?

 

In for someone confirming the handbrake trick on a 997.1tt 6speed car.
