The biggest improvement from PGR3 seems to be the dynamic weather system. Taking one step closer to realism, PGR4 will have rain storms and snow flurries that can strike at any time during a race. The weather effects aren't just for show either; driving will become increasingly difficult as weather conditions worsen and cause the in-game physics to change.
Another one of the new features is a revamped career mode as detailed below:
Drivers will be rewarded with a growing fanbase that'll cheer them on, react to their every move and support them through victory. Just imagine hearing the roar of the crowd as you cross the finish line with your own style and flair.
Last but not least, PGR4 will sport a revised Kudos system:
Flair and driving style will now be just as important as technical skill, as players passing their opponent at full speed will pump their fists and exhibit more emotion as they earn recognition with the revised Kudos system. The Kudos will be worthwhile too, because the new A.I. personalities will be able to perform bold new driving maneuvers as they race side by side with other drivers.
