Honda N600
The roads in Japan outside the cities were very bad in the 1950s
and 60s with speeds of 50 to 60 Kilometres per hour being the
norm, it wasn’t until the five year road building programme
beginning in 1971 that greater speed were possible.
Honda introduced their first front wheel drive car in 1966 the
N360. It was fitted with a transversely mounted air cooled O.H.C
four stroke parallel twin cylinder engine. Honda had extensive
experience of this type of engine in their motorcycles. Other
versions were the N400, N500, and N600, made from 1967 to 1973,
that had engine sizes to match the name. Over 1.1 million examples
had been produced by 1971 when the "N" series cars were replaced.
In 1970 Honda began producing the Z range of two seat miniature
coupe's based on the N range mechanicals, from the Honda Z360 Kia
cars to the Z600 which was for sale in markets other than Japan.
Production ceased in 1972 with over forty-thousand made. As well
as the Z models Honda made the Life model from 1971 to 1974,
larger and with a water cooled engine it was more refined than the
Z models.
Daihatsu began production of a model in the Kia car category in
1966 the Fellow. With a water-cooled two-stroke twin-cylinder
engine of 356cc producing 23hp. It had a front engine, rear wheel
drive layout. It was in production until 1970. Daihatsu's
replacement for the Fellow, was the Fellow Max. First produced in
1970, it had a 360cc two-stroke twin-cylinder engine, located at
the front and driving the front wheels. Subaru replaced the 360
with the R2 in 1969, still with an air-cooled two-stroke engine of
356cc. This was replaced with a water-cooled version in 1971 and
production ceased in 1972. In 1967 Suzuki replaced the Suzilight
with the Fronte 360 LC10, it had a rear mounted lightweight
tree-cylinder air-cooled two-stroke engine the produced 25 hp that
gave it a maximum speed of 110 km/h. Mazda resumed Kei car
production with the Chantez in 1972. It had a water-cooled
two-stroke engine at the front driving the rear wheels. Kia car
sales had increased steadily, reaching a peak of 750,000 in 1970.
Throughout the 1970s the government kept reducing the benefits
offered to Kia vehicles, which combined with ever stricter
emissions standards to lower sales drastically through the first
half of the decade. Honda and Mazda withdrew from the
manufacturing of passenger Kia cars in 1974 and 1976 respectively,
then sales steadily declined, reaching a low water mark of 150,000
passenger cars in 1975, eighty percent less than 1970 sales. Many
were beginning to doubt the continued existence of the Kia car,
New standards were announced on 26 August 1975, increasing the
overall length and width restrictions by 200 mm and
100 mm respectively.
1972 Mitsubishi Minica
Engine size was increased to 550 cc, taking effect from
January 1, 1976. To take advantage in changing regulations,
Daihatsu substituted a 547cc single overhead camshaft
four-stroke engine for the two-stroke engine in 1976 again a
twin cylinder unit. This was carried over to a new body
shell in 1977, the name be changed to the Max Cuore. Production
ceased in 1980. The Subaru Rex replaced the R2 in 1972 and was in
production until 1992. During that time the rear mounted 258cc
two-stoke engine was replaced with a four-stroke until that was
later increased to 490cc then finally to 540cc. A Mitsubishi
Minica with a single overhead camshaft, four-stroke engine the F
4, was introduced in 1972 and was in production until 1989 as with
the Subaru, the engine capacity was increased as regulation's
allowed.
In 1976 Suzuki introduced two new Kia cars the Cervo SS20 a two
seat rear engined model and the Front 7-S a four seat also with a
rear engined both with a three-cylinder inline two-stroke engine,
The Front initially with a 443 cc version later sharing the
539 cc version with the Cervo. Export versions of the Cervo as the
SC100 were fitted with a four-cylinder water-cooled overhead
camshaft engine of 797 cc or 970 cc. The Front 7-S was
produced until 1979 and a later version of the Cervo the SS40
until 1990. Suzuki introduced the first in the line of Fronte/Alto
models the SS30/40 in 1979 and produced it until 1984, it had the
T5B 539cc three-cylinder engine at first that was replaced
by a 543 cc single overhead camshaft three-cylinder four-stroke
engine in 1980. The engine was transversely mounted at the front
driving the front wheels that were sprung by coils struts the rear
axle being dead beam located and sprung by leaf springs. Export
versions of the Alto had 796 cc version of the same engine and was
also in production in India by Maruti as the 800
model. Interest in the one litre engined car in Japan was at a low
ebb in the late sixties and seventies with only three new models
during that period The Subaru 1000 produced between1966 to
1969, it being the first front wheel drive Subaru models
also the first with a horizontally opposed water-cooled
four-cylinder engines in this case with a capacity of 977 cubic
centimetres. The Datsun Sunny B10 also known as the Datsun 1000
had a front engine rear wheel drive layout with a 988 cc
four-cylinder inline water-cooled overhead valve engine. I am
unable to determine the chassis type; but it had independent front
suspension by wishbones and a transverse leaf spring, the live
rear axle was hung on leaf springs. It was in production for only
four years from 1966 to 1970. The Daihatsu Charade was a new front
wheel drive model with a new three-cylinder belt driven overhead
camshaft engine the Daihatsu C series engine of 843 cc or 993 cc.
Japanese Car of the Year in 1979 and was made with
successive revisions from 1977 to 1993. It was assembled from kits
in many countries around the world.
Daihatsu Charade
During the period covered in this chapter the two stroke engine
had given way to the four stroke engine in all models and seen the
emergence of the three cylinder four stroke configuration not seen
since the beginning of the century, an engine type that would
become dominant in the ultralight car in the future. The trend
towards the front wheel drive layout was well under way and would
dominate in the future.
