In 2013, the Mizuiro Motor Company released a kei hatchback called the Kaga, which served as a throwback to their success selling inexpensive kei cars that held their own on the track. While it had a lot to offer in terms of performance and became a strong seller, it was outclassed by its competitors' vehicles, which boasted more interior space and all-around practicality.
Not to be outdone, the Kaizoe (介添え) made its debut in 2015. Taking on a tall, boxy shape, it offered more room while still keeping the weight down to 618 kg (1362 lb). Improvements were also made to the engine, now a 658cc inline-four that runs smoother and quieter than the Kaga's three-cylinder. It makes more power as well, capable of 46 kW (62 hp).

The Kaizoe S in turquoise
Taking after the motorsports-oriented Kaga Cup, a rallycross Kaizoe was entered in several rally events. Its engine output was raised to 217 kW (291 hp), and despite the weight increase to 702 kg (1548 lb), it seemed to be a solid performer.

The Kaizoe Rallysport
After finding out about the Kaizoe's high centre of gravity the hard way, tuners began to fit their cars with widebody kits and stance them. While many tuned Kaizoes were derided for their cheap appearance, they were considerably more stable in corners. One tuner in particular gave their widebody Kaizoe a massive upgrade, replacing the engine with a massive 2328cc turbocharged inline-three churning out 664 kW (890 hp) at its peak. The turbocharger itself is big enough that it protrudes from the front for maximum thermal efficiency.*

*I couldn't flip the engine model around without it turning a pretty hue of "no material" orange. What makes this especially frustrating is that the intakes are facing rearward. If somebody knows how to fix this, please let me know.
