About the Subaru Rex KG1
The third-generation Subaru Rex (KG series) debuted in 1986, marking a significant shift towards a more modern, aerodynamic design compared to its boxy predecessors. While the KG1 trim retained the reliable EK23 two-cylinder engine, this generation introduced advanced features to the kei class, including an optional CVT and supercharging in later years. It was designed primarily for the Japanese Domestic Market but saw export success in Europe and Australia under names like the Mini Jumbo and Sherpa. Today, it is remembered as a quintessential 1980s microcar that prioritised urban efficiency and clever packaging.
