Description
Overview
The Tamiya Audi 90 Quattro Racing recreates one of the most dominant and technologically advanced touring cars of the late 1980s American racing scene. The full-size Audi 90 quattro Racing flourished at American races in 1989, particularly in the IMSA GTO series where it dominated against larger-displacement V8 rivals. Powered by a 2.2-liter inline-5 turbocharged engine producing over 700 horsepower, combined with Audi's legendary Quattro all-wheel-drive system, this car showcased engineering superiority that would influence motorsport for decades to come.
This R/C model assembly kit faithfully captures the aggressive wide-body design of the racing legend, featuring a polycarbonate body that's significantly wider than the road car. The muscular form includes flared fenders, lightweight carbon and aluminum panel details, and the distinctive two-level rear wing that made this car instantly recognizable. Built on the reliable TT-02 chassis with dedicated +4mm offset white dish wheels, this model delivers authentic scale proportions while providing excellent handling characteristics.
