Design & Looks
Early kei cars were simple two‑seaters like the 1952 Auto Sandal and the 1954 Flying Feather. They fit within strict size limits – 3 m long, 1.3 m wide and 2 m high – which forced clever packaging. Over time, models grew a bit more personality: rounded edges, bright colors, and clever storage solutions that made city parking a breeze.
Performance & Mileage
Kei regulations capped engine size at 360 cc in the early years (now 660 cc). Despite the tiny powerplants, manufacturers tuned them for fuel‑efficiency – often over 70 mpg (≈30 km/l). The Subaru 360, launched in 1958, was praised for its smooth engine and supple suspension, proving a small car could still feel lively on winding roads.
Price & Rivals
The government’s 1955 “People’s Car” plan demanded a price below ¥150,000 (about £4,800 today). Subaru, Suzuki, Mazda, Datsun and Mitsubishi all answered the call, turning kei cars into an affordable alternative to larger Japanese models. By 1960, annual sales jumped from a few dozen to over 77,000 units.
