List of Mario Kart 7 pre-release and unused content

These are beta elements for Mario Kart 7.

E3 2010 demo

 * Alpine Pass and Mario Circuit didn't have a ramp where the glider could be activated. Also there were no ramps because Nintendo didn't confirm that tricks would appear in the game.
 * Wuhu Island Loop does not have a ramp on the bridge.
 * Mario Circuit didn't have any ramps present in the grass.

E3 2011 demo

 * The demo included the Spiny Shell with wings in the item roulette. In the final, it is replaced with the wingless version.
 * Several ramps in Alpine Pass are not present.
 * The Screaming Pillars in DK Jungle do not have the occasional scream.

Scrapped Customisation Parts
A kart frame named Bullet Duck was mentioned on several websites, but was not seen in the game. Also a kart called Banana Buggy was mentioned, which is likely an early name for the Bolt Buggy, because this kart is called Banana Buggy in many languages other than English (excluding Spanish, in which case it is called the Banana Kart). The Streamliner was mentioned due to a recognition mistake. It was actually the Blue Seven.

Other

 * Oddly, in the Nintendo Press Conference 2011 Footage, the Lucky 7 doesn't have a chequered border. Said border is strangely present in the final version.
