History

The Shincha was co-developed by HAAI and Fokkusuōto from 1989-1998. The car made it’s debut on a motor show on the 17th of January 1991, getting the most interest shown towards it from all the kei cars on display. Following the good reception of the car, it was released to the public in October of 1991 with a price tag of approximately 18 400$. The economy and kei size made it quite affordable, but it was slightly difficult to work on due to the size limitations.

In 1997, the Shincha saw a minor facelift, getting turbos in the higher trim ranges which were boasted to improve fuel economy and power delivery even further. With them came the fully performance-oriented SUPER-TURBO, but with a slight catch. The engine produced less than the other top-of-the-line turbo models. Instead of the 64hp as allowed by kei regulations, the SUPER-TURBO made only 60hp and with a big economy hit with the 95 RON octane that the car was advertised to use. But for those who still bought the “lesser model”, got advised to use 98 from the sellers themselves. The seemingly pointless TURBO switch in the glovebox overrode the ECU to make full advantage of the higher octane, pushing the engine up to 82hp and 88lb-ft of torque, with a slightly improved fuel economy.

In September of 1998, a test driver in a car magazine figured the quirk out, writing about it in his segment. This led to a court case for Fokkusuōto, through which they settled on being banned from the ability to sell for the kei segment again. Nowadays, it’s debated whether or not the Shincha SUPER-TURBO will remain the undefeated performance kei car forever, or whether it even is a kei car at all.

Big thanks to Sukki Blue for collaborating with me on this. The engineering part was almost entirely done on his part. It was a blast to make this.
