The Daihatsu Hijet (Japanese: ダイハツハイゼット) is a cabover microvan and pickup truck produced and sold by the Japanese automaker Daihatsu since 1960. Despite the similarities between the Hijet name and Toyota's naming scheme for its trucks and vans (HiAce and Hilux), the name "Hijet" has been in use for Daihatsu's Kei trucks and Microvans since 1960, over two decades before Toyota took control. "Hijet", when transliterated into Japanese, is very similar to "Midget", one of Daihatsu's other mini-trucks. The Hijet competes in Japan with the Honda Acty, Subaru Sambar, Mitsubishi Minicab, Suzuki Carry and the Nissan Clipper.
The first Hijet received a 360 cc two-stroke engine, as was dictated by the kei car laws of the time. The Hijet's development has long followed the evolution of Japan's kei regulations, with an increase to 550 cc in 1976 and then 660 cc for 1990. Exterior dimensions also increased from 3.0 m × 1.3 m (118 in × 51 in) to 3.4 m × 1.475 m (134 in × 58 in). Export versions have usually been slightly larger as bigger bumpers and sometimes wider bodies are fitted. During 1980 the two millionth Hijet was built.
The first vehicle to bear the name Hijet from Daihatsu was a kei truck in November 1960, with the enclosed light van model following in May 1961. The first generation Hijet used a conventional front engine, rear-wheel-drive format with the driver sitting behind the engine, in a similar pickup fashion. The exterior dimensions and engine displacement were in compliance with "kei class" regulations in Japan at its introduction. The 356 cc engine produced 17 PS (13 kW), making for a top speed of 75 km/h (47 mph), normal numbers for the class at the time. As a result, the ability to carry loads was very much reduced. In 1964, the Hijet received a facelift, replacing its cheerful body-colored grille with a more conventional chromed unit.
A heavier duty model of the Hijet, the New-Line (L50P/L50V), arrived in January 1963. It was a half-metre (20 in) longer and could carry 500 kg (1,102 lb) thanks to a larger, 800 cc engine with 41 PS (30 kW). Developed with an eye to export markets, this car did not meet the strict kei car standards of the time and sold only in small numbers. When the first generation Hijet was replaced in February 1966 the New-Line was discontinued.
To maximize cargo carrying space while still staying in the "kei" class regulations, a cabover approach was adopted in 1964, offering buyers the choice between the first generation style or the cabover approach. This generation appearance was also introduced as the larger "New Line Cab" Daihatsu cabover truck (S50, S50T), replacing the earlier L50 New Line. As for its predecessor, it shared its engine with the Daihatsu Compagno. The New Line Cab was built from February 1966 until March 1968.
The cabover bodystyle approach appeared after the 1950 Volkswagen Type 2, the 1961 Ford Econoline, the 1961 Chevrolet Greenbrier, and during the same year as the Dodge A100.
First model change from previous generation saw minor improvements, to include installation of the front door hinges to a conventional implementation as opposed to the rear-hinged door. The design was boxier over all, with a more wedgy appearance. This generation was also offered as an all-electric truck and van.
In September 1971 the fourth generation Hijet appeared, with all-new sheetmetal, initially available only as a truck. The engine remained the ZM 360 cc two-stroke two-cylinder, while the rear suspension reverted to a live, leaf-sprung unit. In February 1972 a new Van was presented, originally marketed as the "Slide Van" as it now featured sliding doors on both sides in addition to a top-hinged tailgate. In September 1974 the front clip and rear bumper underwent light changes to accommodate full-size yellow license plates (hitherto, kei cars had been equipped with smaller plates than normal).
In October 1976 the four-stroke Hijet 550 appeared, with the new 550 cc AB20 engine taking full advantage of the recent new kei regulations. Bigger bumpers meant that all Hijets built after this date are slightly longer, as the 360 received the same external changes simultaneously, including a new front clip. To reflect the new engine, the 550 received the new chassis code "S40". In export trim, where it was sold as the Daihatsu 550 Cab and Cab-Van, this engine has 30 PS (22 kW) at 5,500 rpm, and 4.2 kg⋅m (41 N⋅m; 30 lb⋅ft) at 4,000 rpm. The 550 Van had an advantage of a higher carrying capacity than the 360 Van, at 350 rather than 300 kg (772 and 661 lb respectively).
Less than a year after the introduction of the 550, the wider and longer Hijet Wide 55 (S60) appeared, but the Hijet 550 continued in production and even underwent a facelift in April 1979 and now carried a blacked out grille. In April 1981 the four-stroke S40 Hijet 550 was discontinued, but the two-stroke S38 continued to be available until August 1981 as a low-cost version (by which time the sixth generation Hijet was already on sale). The later ZM-engined versions had 24 PS (18 kW). The two-stroke was also popular in many Southeast Asian markets, where emissions regulations were more lax and its lower purchasing price had a bigger impact.
In April 1977, production of the truck version of the fifth generation began. Called the "Hijet Wide 55", to draw attention to its wider body and bigger 550 cc engine, this was the first Hijet to reach export markets in any serious numbers. The 547 cc AB20 was a four-stroke, water-cooled two-cylinder unit with a single overhead camshaft and balance axle. Power output is 28 PS (21 kW) at 5,500 rpm, while max torque is 4.0 kg⋅m (39 N⋅m; 29 lb⋅ft) at 3,500 rpm. Export versions, which had to face less stringent emissions requirements, offered 30 PS (22 kW) at the same engine speed and 4.2 kg⋅m (41 N⋅m; 30 lb⋅ft) at 4,000 rpm. The only transmission installed is a four-speed manual with a floor-mounted shifter; export versions could reach a claimed 105 km/h (65 mph) top speed.
The engine is mid-mounted just behind the front axle, and access is gained by simply lifting the front seats. Chassis code is "S60", with the succeeding letter "P" signifying a simple pickup bed with one opening flap; "T" for the three-way dropside pickup; and "V" for the vans.
Three months after the introduction of the pickups (in June 1977), a glassed van with sliding doors and also a "panel van" version were released. The panel van was simply a truck with a box mounted on the rear; this version was not exported. For export, a van version without windows or rear seats was preferred. A low floor dropside bed was added in December 1977, and a minor facelift took place in September 1978. The changes were limited to different colored bumpers and headlight surrounds, and a changed metal grille insert featuring a larger "D" logo. All versions were available in either Standard or Super DeLuxe trims, but in March 1979 a comparatively luxurious "Custom EX" version of the light van was added.
In September 1979, the Hijet Wide 55 underwent a more thorough facelift: A new front clip with a single-piece grille was the most obvious change, while inside there was a new more sculpted dash as well as more comfortable seats which received adjustable backs. The two millionth Hijet was an S60 built during 1980. Production continued until replaced by the sixth generation Hijet in 1981.
In March 1981 the all-new S65 Hijet appeared, now on a slightly longer wheelbase but with the same AB20 engine. New was a flat-floor option for the Vans, and also new was a high-roof option. Power output is 28 PS (21 kW) at 5500 rpm, while max torque is 41 N⋅m (4.2 kg⋅m; 30 lb⋅ft) at 3500 rpm. Most mechanicals were originally the same as before, but in March 1982 the S66, a new four-wheel drive (from October 1983 with optional free-wheel front hubs and front-wheel disc brakes) appeared. From 1982, export versions generally received a torquier 843 cc three-cylinder engine (CD20), called the Daihatsu 850 Cab. The 850 also benefitted from twelve-inch wheels rather than the ten-inch ones used on the smaller-engined models. In 1983 a one-liter version was also made available. In un-catalyzed trim, as sold in many export markets, this model produces 47 PS (35 kW) JIS at 5600 rpm. The four-wheel-drive Hijet was also exported beginning in 1985.
There was also an S70 series version of the S65. Indonesian-built Hijets (by P.T. Astra International) had a longer body on the same wheelbase, and was available with a variety of locally developed bodywork. They were fitted with the one-litre engine subsequent to a decree by the Indonesian government that the smallest car engine built in the country by 1985 would have to be one liter. The rear portion of the body was developed locally, and the dies were also manufactured in Indonesia, thereby lowering licensing fees and minimizing imports. A variety of different minibus bodystyles were offered by a number of small bodybuilders. This Hijet was the most successful model in the fastest growing segment of the market, and represented one eighth of all local vehicle manufacture in 1983. In late 1985 the Indonesian-market Hijet received a light facelift, featuring a new silver-colored grille with five small openings on the right-hand side. This generation of the Hijet was kept in production in Indonesia until 1992.
Also in 1983 the Hijet Jumbo appeared, a high-roofed extended cab pickup with a shorter bed. This meant that there was space for more comfortable seats, with considerable more travel and folding seatbacks. The resulting rear compartment offered small luggage spaces, a flat-folding passenger seat, and a small luggage rack above. The two-wheel Jumbo was available with a fifth gear, as were some versions of the Atrai passenger van. There was also a Hijet Climber series (two- or four-wheel drive), these were fitted with bigger off-road tires and a limited-slip differential.
The S65 was also sold as the Hijet Atrai Van from September 1981, a version specifically intended for passenger use. From October 1983 this became a separate badge in the Japanese market, where the Atrai remains separate from the more workmanlike Hijets. There was also a handicap accessible version of the Hijet S65V, which could accommodate a folding wheel chair. The most surprising news was probably the addition of a turbocharged version in February 1984, also available with four-wheel drive.
A subsidiary of FAW Tianjin began producing the S65 Hijet in 1984, originally as the Tianjin TJ110 but later as the Huali Dafa. The Chinese-built trucklets were only available with two-wheel drive and the 843 cc three-cylinder CD engine, offering 41 PS (30 kW) at 5,500 rpm. The high roof was also available in China. The Huali Dafa was used as a popular taxicab and production ended in 2002.
