Why don't the manufacurers release the vehicles with higher power to start with?

Manfacturers design and build their vehicles for a global market. Due to this they must meet a wide range of fuel and emmisions standards, they also need to take into account altitudes and climates. Luckily for us there is plenty of room to move under European and Australian tolerances, which allows us to extract more performance from the vehicles whilst still being withing the components maximum tolerances.
