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 5,500 rpm, while max torque is 41 N·m (4.2 kg·m; 30 lb·ft) at 3,500 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 received a torquier 843 cc three-cylinder engine, called the Daihatsu 850 Cab. In 1983 a one-liter version was also made available.
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.
