Top speed for Oldsmobile alero sedan?

The top speed of an Oldsmobile Alero sedan isn't a fixed number readily available from a single source. It varies depending on the specific model year (as engine options and other factors changed), the condition of the vehicle, and even road conditions.

However, based on various sources and owner experiences, you can expect the top speed to be in the range of 110-125 mph. This is a *theoretical* maximum; attempting to reach this speed is dangerous and illegal. It's also important to remember that this speed will likely only be achievable under ideal circumstances, and real-world conditions will significantly reduce the attainable speed.
