The Ford Fiesta ST RX43 was initially developed by M-Sport as Ken Block’s rallycross car for the 2013 Global Rallycross Championship and X Games. It also served as the lead picture car in Gymkhana SIX and Gymkhana EIGHT.

Engineered for massive torque and explosive off-the-line launches, it was later duplicated by M-Sport as the RX43B for the 2014 FIA World Rallycross season due to scheduling overlaps. Its setup—including suspension, differentials, and engine mapping—is custom-tuned for every event.
