All Mario Kart games have difficulty modes named after engine classes: 50cc, 100cc, 150cc etc. In some Mario Kart games, the engine classes do not actually correspond to in-game variables, so e.g. there is no single value that is "50" for 50cc and "100" for 100cc. Instead, each engine class is custom-crafted with different values and the "cc" numbers are just for the player's benefit.

However, in Mario Kart 7, the "cc" number is actually a real variable in the game's code that can be changed to create any possible engine class. If it is made greater than 150cc, the karts predictably become even faster. Interestingly, there is behavior for negative engine classes, which is shown in the footage.

All regular acceleration (so Rocket Start being exempt from this) actually accelerates the kart backwards. Note how Yoshi appears to go forward from the Rocket Start but then immediately starts accelerating backwards uncontrollably.
