As a result of the way the legislation was written when a vehicles engine is operating in a region where it might be on an emissions drive cycle it operates in quite a different manner than when it is outside such a region. The problem is when transitioning from one mode of operation to another it is almost impossible to keep the emissions to a minimum, it is equally detrimental to fuel economy and driveability. In short the way Automotive OEMs calibrate vehicles because of the emissions legislation and competitive market in which they operate has caused almost all of the cars on our roads today to have reasonably poor emissions, fuel economy and performance relative to what is actually possible. Auto Upgrades envisaged cars that are calibrated to deliver optimum performance, drive-ability, fuel economy and great real world emissions.
