History of the Toyota Coaster

First generation (U10/B10; 1969)

The Coaster was introduced in February 1969 in 22- and 26-seat forms, using the platform of the Dyna truck. It came with the 1,994 cc 5R petrol engine or the 2,481 cc 2J diesel, all with a four-speed column-shift gearbox, and air conditioning was optional on deluxe models. In February 1972 the 2J diesel gave way to the 3.0-litre B engine with a five-speed column-shift gearbox. A 1977 update moved the range to the B-series codes, added a 2.2-litre 20R petrol, replaced the diesel with the 3.2-litre 2B and introduced a high-roof body. Column shifting was dropped in November 1979, and a 2.4-litre 22R petrol arrived in August 1980.

Second and third generations

The second generation of May 1982 brought a new body with a wraparound windscreen, thicker rear pillars and a single-piece passenger door for high-roof models; the 2B diesel was replaced by the 3.4-litre 3B. The third generation, introduced in January 1993, had a more aerodynamic body and engines including the 4.2-litre 1HD-T turbo-diesel, the 4.2-litre 1HZ and the 3.4-litre 3B. Four-wheel drive arrived in November 1995 with the BB55/BB58, and the 4.1-litre 15B-F diesel joined the range.

The hybrid and the fourth generation

In August 1997 Toyota launched the Coaster Hybrid EV, a series hybrid using a 1.5-litre 5E engine to generate electricity for the motor. The engine ran at a fixed speed, which cut noise, vibration and emissions and improved fuel economy, and it produced 95 PS; the bus was intended for urban use. According to Toyota it was the company’s first production hybrid vehicle, arriving before the Prius, and it stayed on sale until 2007. The fourth generation was unveiled on 22 December 2016, the first vehicle fully redesigned by Toyota’s new Commercial Vehicle company, with airbags, stability control, a ring-frame body and seat-belt pretensioners as standard.
