IFMAR 1:8 IC Track World Championship
From Wikipedia, the free encyclopedia
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 even-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. These cars are typically four-wheel drive (4WD) and feature lightweight pan-style chassis combined with highly aerodynamic bodyshells, commonly based on fill sized Le Mans Prototype (LMP) designs, optimised for high-speed racing on asphalt circuits.[2]
The championship is one of several IFMAR world titles in radio-controlled car racing, alongside categories such as the IFMAR 1:8 IC Off-Road World Championship and the IFMAR 1:8 Electric Off-Road World Championship.[1]
The inaugural 1:8 IC Track World Championship was held in 1977.[1] Early editions were primarily dominated by North American competitors and 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.[3]
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.[2]
