What is the top speed of my car?

Top speeds will obviously vary with the modifications to the vehicle.  However, the top speeds for stock vehicles are in the following neighborhood: 
-  1G AWD:  around 140 MPH / 225 km/h 
-  1G FWD:  140 MPH / 225 km/h 
-  2G AWD:  somewhere around 130-140 MPH. 
-  2G FWD:  some cars are speed limited to 130 MPH - see What are the differences between a M/T turbo and an A/T turbo?
