Only if you're talking about the trap speed of a car over a measured distance. If a car has an indefinite distance to accelerate to its maximum speed it will reach that same maximum speed as another car with more or less weight; it's only speed-limiting factor at that point is friction in the drivetrain (wheel bearings, gears, rolling friction from tires) and in the air over the car itself (drag or air resistance). It's just like the concept of terminal velocity; a falling object will keep accelerating until its air resistance becomes equal to its gravity; then it will continue to fall at a steady speed.
