Mario Kart Wii Vehicle Chart

The following is an extensive chart containing every vehicle in Mario Kart Wii, ranked in all seven categories from 1 to 36 by their statistical values. Red Highlights are Small Vehicles (Red for Karts, Pink for Bikes), Blue Highlights are Middle Vehicles (Blue for Karts, Light Blue for Bikes), and Green Highlights are Large Vehicles (Green for Karts, Light Green for Bikes).

Baby Daisy

History:

When they were children, Luigi and Daisy were known to hang out on occasion. From far off Sarasaland, Daisy would often visit the friendlier Mushroom Kingdom, but as things turned darker, the Baby Versions of Mario, Luigi, and even Peach found themselves transported to a calmer future where games reigned rather than battles with the likes of Baby Bowser, Kamek, and Princess Shroob. Baby Daisy was furious that Baby Luigi had left her, although he was admittedly fretful of her driving. She was eventually able to contact Prof. E. Gadd and get herself transported into the future as well.

Wii:

Mario Kart Wii is the first of only two appearances of this desperately unnecessary character. The game makes up for this however, but making Baby Daisy both one of the better Small Drivers and incessantly cute. Every racer in Wii has access to Six Karts and Six Bikes of his or her specific Size Class, all of varying stats to suit different playing styles. Additionally each character adds his or her own bonuses to various stats. Baby Daisy is the fastest Small Driver in the game, tied with Luigi, and the second-heaviest, tied with Baby Peach. She also has a small Mini-Turbo Bonus, the only Baby to do so. Her Vehicle-Specific Stats are as follows:

She really takes best advantage of the Blue Falcon's blistering speed, which is very un-Small-like in nature, but her natural boosts help to counter the usual weaknesses of any Small Character. The Tiny Titan or Jet Bubble are probably going to be better options. Her one Staff Ghost is on Moo Moo Meadows where she uses the Booster Seat in 01:37.856. The Expert Staff Ghost on the same track pulls a 01:25.909 in the Bullet Bike, which is another great Vehicle for her. Baby Daisy is just one of the best Small Drivers around.

Tick Tock Clock

History:

Within Princess Peach's Castle, on the third floor there is a Mystical Clock. The records of its existence go back as far as the construction of the castle itself and it's possible that the structure was built around its time-warping energies rather than the other way around. The Clock is actually a portal to an infinite dimension where time is as manipulable as paint on a brush. It is an extremely dangerous place to explore, but after Mario was able to use the Star Power to conquer its perils he pressured Peach to turn it into a racecourse for profit. Peach never felt great about doing so however, and eventually turned the rights over to Daisy. It remains a dangerous locale for explorers and racers alike, not only because of the deep mysteries surrounding its power and origins.

DS:

This course is actually a relatively simple Figure 8, although there are a good amount of moving parts and gears to throw riders off. Beware of the massive pendulum as well as the spinning clock hands. If you travel in the correct direction of the gears racers can get a bit of a boost but they are hindered by traveling in the opposite direction. It's actually a course more suited for fast Drivers who can haul ass on straightaways with minimal correction (and luck) needed to avoid the pendulum and other hazards. Someone in the ROB-BLS would do nicely here.

The Ghost here is Daisy for some reason who does a 1:54:903 in the Light Dancer. This track has only appeared in DS although it's popular enough to be a likely candidate for a remake someday.
