Mario and friends come back for a new installment of the infamous franchise, on Nintendo Wii. There are New features in this installement such as, an online racing mode, new motorbike vehicle types, a special balancing system for new and veteran players, and (in its initial release) a special Mario Kart wheel packaged with the game. There is also a new trick system, you can now perform tricks in the air by moving the steering wheel, or Wii Remote, respectively.
Nintendo Wifi
It will support an online racing mode where players will be able to go against each other in a single race racing simultaneously and an online battle mode.It has been confirmed that it will also feature 12 player online races. It has also been confirmed that there will be online leagues and rankings along with local rankings, which might be on a whole separate channel.

Weapons
The game would feature many of the old weapons and items that have been used in past Mario Kart games, and that a number of new items are also being added.
New:
1. POW block: it will hover over your players's head, and you'll need to jump three times in a specific rhythm to get rid of it…or you'll spin out. - Total CTR rip off
2. Cloud : it will give your player a boost of speed for as long as you hold it, but it has the side-effect of zapping your kart with lightning which will shrink your kart if you hold onto it for too long. It's an item that can be passed from kart to kart by bumping into your competition, almost like a shrinking hot potato.
