IFMAR 1:8 IC Track World Championship

The IFMAR World Championship for 1:8 IC Track Cars (officially the IFMAR 1:8 IC Track World Championship), commonly known as the IC Track Worlds, is an international radio-controlled car racing competition sanctioned by the International Federation of Model Auto Racing (IFMAR). The championship has been held biennially in odd numbered years since 1977.^[1]

The event is contested using 1:8 scale on-road cars powered by internal combustion (IC) engines running on a nitromethanol fuel mixture.

History

The inaugural 1:8 IC Track World Championship was held in 1977.^[1] Early editions were primarily dominated by American & British manufacturers, reflecting the origins of competitive radio-controlled car racing.

During the late 1980s and 1990s, European drivers and manufacturers became increasingly competitive. Italian driver Lamberto Collari emerged as a dominant figure in the category, winning multiple world titles between 1989 and 2009.^[2]

From the 2000s onwards, Japanese and European manufacturers such as Mugen Seiki, Kyosho, and Serpent have been prominent, contributing to ongoing advancements in chassis design, aerodynamics, and engine performance.^[3]
