Emissions and safety regulations conspired to compel significant changes to the fourth-generation MG Midget. The traditional A-series engine was replaced by a 1493cc engine from the Triumph Spitfire - this engine, while similar in output to the 1275cc A-series, was better able to cope with increasingly-stringent emissions regulations. Large black rubber bumpers were fitted front and rear, and the suspension ride height was raised to better withstand crashes with larger vehicles.
