* Gear ratios: Different gear ratios will affect the top speed achievable.
* Tire size: Larger tires will change the effective gearing.
* Road conditions: Wind resistance, road grade, and even air density play a role.
* Vehicle modifications: Any modifications to the engine, exhaust, or other performance aspects will alter the top speed.
While factory specifications are rarely given for top speed, you'll often see estimates ranging from 140-150 mph for a stock 1996 Camaro Z28. However, these are *estimates* and reaching these speeds is not recommended due to safety concerns and potential legal ramifications. It's important to remember that top speed is not the primary focus of a car's design and reliable data is rarely released.
