The two-door Honda Z debuted in October 1970 and was marketed until 1973 in most countries. American sales (only with the larger 598 cc engine) lasted for model years 1970 through 1972, ending prior to the 1973 introduction of the
Civic. Marketed as the "sport coupé" version of the
N600, the two were sold side by side at American motorcycle dealerships until the first stand-alone automobile dealers opened to market the Civic. Total production was 40,586 units. In certain countries, such as the US, the Z600 name simply reflected the engine's size of . The smaller-engined Honda Z360 was available in Japan (and other markets, such as Australia) with a twin. In the UK they came only in 600 cc form and were called simply "Honda Z" with no mention of the engine size in the name. As with all cars in the
kei class, the Z360's specifications were tightly governed. The Z360 originally featured an air-cooled, 354 cc, two-cylinder
SOHC engine with a four- or five-speed transmission driving the front wheels. Outputs were at 8,500 rpm for the Act and Pro versions, and at 9,000 rpm for the sportier TS and GS models. The Z600 model's 598 cc
SOHC engine was rated at . In December 1971, the Z360 received a facelift and a water-cooled engine, it also produced at 9,000 rpm. Only a month later, the 31 PS engine used in the lower spec variants (Standard, Deluxe, Automatic, Custom) also became water-cooled. The engine's technical achievements reflected influences from Honda's larger, 1.3 L, air-cooled four-cylinder used in the
Honda 1300 coupe and sedan. The Z featured
coil sprung and independent front suspension and leaf springs on a beam axle rear suspension. The interior accommodated two adults, with a very small rear seat. A rear glass hatch with a black plastic surround opened to a shallow cargo area. Below the cargo area a compartment, accessible via a lid beneath the number plate, held the spare wheel and tools. Later versions, after a November 1972 facelift, deleted the extra lid and also moved the license plate down to the position it vacated. These also received the new
EA engine of , now only available in a more powerful, version. Production ended in 1974, after the new Civic had arrived and the
oil crisis had diminished the market for "fun" cars.
Europe In Europe only the Z600 was marketed, as the Z360 had been considered underpowered. 918 cars were sold in Europe, most of them in France and Switzerland. A large number of these cars found their way to Germany (where it had not been marketed), where the engines were downsleeved to 242 cc in order to fit a particular "Class IV" category of
driver's licenses which did not require an exam. These models first appeared in 1969 after the last 250 cc car in regular production, the
Goggomobil 250, had been discontinued. The engine offered from and provided a top speed of . ==1998–2002==
