Mario Kart 8 in-game statistics
The following tables include all statistics for the both the drivers and vehicles part of Mario Kart 8 in the format used internally by the game, as well as the tables used to convert those statistics in in-game statistics. These data are the ones present in version 4.1 of the game.
Statistics in in-game format
Just like Mario Kart 7, the game stores statistics for drivers and parts in points. In each statistics, the sum of the points for the driver, body, tires and glider is a number ranging from 1 to 20, called Level (Lv) in Mario Kart 7, that then determines the values of the related in-game statistics. To obtain the value shown in the bars of the menu, three points are added to the Level and the result is divided by four. The following statistics are used by the game:
Bodies' Statistics (BD)
Drivers' Statistics (DV)
Tires' Statistics (TR)
Gliders' Statistics (WG)
Statistics Translation Tables
The following tables are used by the game to convert the points of each statistics into actual in-game stats.
Important notice: since Mario Kart 8 in-game statistics are directly derived from Mario Kart 7 and since in that game the statistics' tables included headers for columns and rows, that have not been included in Mario Kart 8 tables, the names of such headers will be used here as well, denoted in italics. In the case of anti-gravity statistics, that are still directly derived from preexisitng Mario Kart 7 statistics, only the common part of the headers will be used, still denoted in italics.
There are three in-game statistics related to weight, that are known in Mario Kart 7 as KartBound_MassL, KartBound_MassH and KartBound_MassD. KartBound_MassL is used when the vehicle on a standstill is bumped by other vehicles using a boost given by a Dash Mushroom, KartBound_MassH is used when bumping other vehicles using a boost given by a Dash Mushroom, while it's not known in which conditions KartBound_MassD is used.
Acceleration is determined by two factors, whose names in Mario Kart 7 are Drive_AccLmtFwd and Drive_SpdKfFwd. Drive_SpdKfFwd actually determines how fast the vehicles accelerates, while Drive_AccLmtFwd works as a limiter, fixing the maximum amount of speed increase per frame. It is important to note that, while Drive_SpdKfFwd determines relative acceleration, i.e. how much the fraction of current speed to maximum speed increases over time, Drive_AccLmtFwd determines the maximum increase in absolute speed per frame, i.e. the maximum amount of distance units/frame that can be added to the current speed in each frame. Since the top speed is relatively low in all engine classes except for 200cc, Drive_AccLmtFwd is very frequently not a limiting factor, causing different acceleration values to have the same effective acceleration.
On-Road Traction (ON)
This statistic is unaffected by the Level. The related in-game statistics in Mario Kart 7 have SlipRt in their names. It controls how much the vehicle slips in normal (not off-road) sections of the tracks, but is set to the same value of 0.75 regardless of the level.
(Off-Road) Traction (OF)
There are 2 in-game statistics related to Traction, named BrakeRt and SlipRt in Mario Kart 7, that are applied to three types of off-road terrains (named DIRT, SAND and ICE in Mario Kart 7), each one of which has three degree (indicated with L, M, H in Mario Kart 7). BrakeRt is the relative maximum speed while in off-road terrains, while SlipRt determines how much the vehicle slips in said terrains.
There are two in-game statistics related to Mini-Turbo, called Dash_FrmMiniT_Lv1 and Dash_FrmMiniT_Lv2 in Mario Kart 7. The first is the length of the Mini-Turbo boost in frames, the second is the length of the Super Mini-Turbo boost in frames.
Speed (SL, SW, SA and SG)
There are two in-game statistics related to speed, named SpdMaxFwd_L and SpdMaxFwd_H in Mario Kart 7: the first is the maximum speed without coins, expressed in distance units/frame, the second is the maximum speed with 10 coins, expressed in distance units/frame. Interestingly, Air Speed has only one in-game statistics, called Wing_SpdMaxFwd_N in Mario Kart 7 and expressed in distance untis/frame as well, suggesting that the maximum speed while gliding is unaffected by coins.
Handling (TL, TW, TA and TG)
There are three in-game statistics related to handling, known as Drive_DirRotH, Drift_DirRotH and AutoDrift_ChargeRt in Mario Kart 7. The first is proprotional to the angular velocity while steering and to the angular velocity during the automatic drift, the second determines how much the drift can be widened or made sharper, while the third is how fast is the automatic drift charged while steering in a direction. When at full charge, the automatic drift begins. Drifting and automatic drifting can begin only if the speed of the vehicle is greater than 55% of its top speed, when such treshold is passed, the smoke coming out of the exhaust pipes suddenly disappear. Air handling has only two in-game statistics, named Wing_StickLR_Roll and Wing_StickLR_Move in Mario Kart 7, that are respectively proprotional to how much the vehicle rolls (tilts sideways) and actually changes direction over time while steering during a glide.
