There are 3 versions of the Honda Civic Si.
- The first Honda Civic Si was released in 2001. It was modeled after the 1:1 car produced for the SEMA Show.
- The second Honda Civic Si was released in 2002 and is very similar to the 2001 casting, except this version has door mirrors and an opening hood.
- The third Honda Civic Si was released in 2003. This hatchback has dropped the "Si" and added "Type R" in more recent releases.
- The fourth Honda Civic Si was released in 2006. Like the 2001 casting, it was modeled after the 1:1 car produced for that years SEMA Show. A special version of this casting was actually given out at the SEMA Show in 2006. Hot Wheels produced a "Wide Body Kit" that can fit any 1:1 2006-2008 Honda Civic to make it look like this casting.
