The first thing big difference I've discovered playing Trackmania 2 over its predecessor is navigating narrow turns. Wonder Hairpin is setup to help you learn just that by way of a long sweeping right-hander that narrows the further you drive in. The trick is maintaining a power slide through the apex while setting up the car for a clean exit. The support beams near the finish just spice up an otherwise simple track.
As always intros and replays are setup for your viewing pleasure.
