Factors that *do* directly influence a car's top speed include:
* Engine power and torque: More powerful engines allow for higher speeds.
* Aerodynamics: A more aerodynamic design reduces drag, allowing the car to reach higher speeds.
* Gear ratios: The transmission's gear ratios determine how engine power is translated to wheel speed.
* Rolling resistance: The friction between the tires and the road affects speed.
* Weight: A lighter car requires less power to reach a given speed.
While wheel placement indirectly influences some of these factors (for example, a wider track might improve stability, indirectly affecting handling at high speeds), it doesn't directly add or subtract from the car's potential top speed.
