Marque developed by the Colt Car Co. in the UK to circumvent the 11 per cent market share limit that Japanese automakers had set themselves in the 1980s. Someone at Colt noticed that Mitsubishi Australia was manufacturing its own version of the Galant Σ (A160), the Sigma, and that it would not qualify within the 11 per cent. As an exercise, it did not work. The cars were rugged and simple but nothing special; the Australian origin, played on in advertisements at the time, meant little to British consumers. The cars lasted less than a year on the market (1982–3); some sold under their original Mitsubishi Sigma name very briefly after Colt became Mitsubishi and there was a change within management at the importer.
