The Daihatsu Fellow Max is a small Japanese automobile in the Kei car class. Originally introduced as the Daihatsu Fellow, the name was partially retained for its successor, the Max Cuore (1977), and then revived in 2000 for the Daihatsu Max.

360cc era

Fellow

On 9 November 1966, Daihatsu introduced the Fellow, also known as Daihatsu 360 in export markets. Originally only available in DeLuxe and Super DeLuxe equipment levels, a Standard version joined in February 1967. Also available with a wagon body (Fellow Van), as a mini-pickup truck and as a panel van from June 1967, the L37 was conventionally built with a front-mounted engine and rear wheel drive. It used a 23 PS iteration of the 356 cc, water-cooled two-cylinder two-stroke "ZM" engine already seen in the Hijet and a four-speed manual transmission. The self-lubricating ("Oil-Matic") little engine weighed only . The Fellow was the first Japanese car to be equipped with rectangular headlights.

As a result of Honda's 31 PS N360 being introduced early in 1967, a Kei-car horsepower war broke out, with Honda, Subaru, Suzuki, Mazda, and Mitsubishi contributing competitors. Daihatsu's response, the Fellow SS, was presented at the 1967 Tokyo Motor Show in October but did not go on sale until June the next year. A Le Mans-style sportscar prototype, the P-5 with the SS engine was shown alongside. The 32 PS "SS" could do the 400 meter sprint in 21.2 seconds.

The Fellow also received a slight facelift in October 1967, with a new dashboard and steering wheel most noticeable. Another minor change came in January 1969, with a fixed driver's side headrest and seatbelts installed because of new safety regulations. In July, along with what was literally a facelift (the front bumper was now mounted higher), the lesser engine's output increased to 26 PS and a comparatively luxurious "Custom" version was added at the top of the lineup. The size of the taillights also increased somewhat. An electric version called the Daihatsu Fellow Van EV went on sale in September 1969.

Fellow Buggy

A beach buggy version was introduced simultaneously with the other three body styles. While highly prized by collectors today, the Buggy only sold about 100 examples and was only available for a single model year. The 440 kg Fellow Buggy was not actually a "real" Fellow, as it was built on a Hijet S37 chassis, with fibre-reinforced plastic bodywork. The Buggy also used the Hijet's lower powered () engine, providing a top speed of .

Fellow Max

In April 1970, the front-wheel drive L38 Daihatsu Fellow Max was introduced to replace the rear-wheel drive Fellow. Originally only available as a two-door sedan and three-door van (L38V), a hardtop coupé with a lower roofline and a somewhat baroque front-end treatment was added in August 1971 (L38GL). SL and GXL Hardtops received standard front disc brakes. In October 1972 a four-door version (L38F) appeared; it was the only four-door Kei car at the time of its introduction. Dimensions were 2,995 x 1,295 mm as dictated by the Kei car regulations, although the wheelbase was stretched by 100 mm to 2,090 mm. The engine was a 360 cc two-cylinder two-stroke ("ZM4"), offering at the time of introduction. In July 1970 the SS version appeared, featuring a twin-carb, 40 PS (SAE) version of the ZM engine (ZM5) - a specific output of over 112 PS per litre. Top speed was 120 km/h, compared to 115 km/h () for the lesser versions. This highly tuned engine had an 11:1 compression ratio, versus 10:1 for the ZM4 engine, and required high octane gasoline. With a narrow powerband at the high end of the range, its expansion chambers in the front and rear meant that noise levels were elevated.

In October 1972, for the 1973 model year, engine outputs dropped somewhat, to 31 and 37 PS respectively to lower fuel consumption and meet new, more stringent emissions standards. These engines were called ZM12 and ZM13 respectively.

In export markets, this car was usually sold simply as the "Daihatsu 360". In Australia, where the car went on sale in early 1972 as a two-door sedan, it was called the Max 360X. It was the cheapest new car available in Australia at the time. Unaffected by emissions regulations, it was equipped with the 33 PS version of the engine; in a period road test by Wheels magazine it reached and managed the sprint to in 33.2 seconds. It was also sold as the Daihatsu 360X in New Zealand.
