Avia » D-series
The Daewoo Avia's new management team staked a demanding goal consisting of development and implementation of a completely new medium duty truck, which would cover the 6 to 9 tonnes weight class and would be fully competitive in the western markets in terms of design. The vehicle cab, which got a completely new design and provided a maximum comfort both to driver and crew, was the most significant component of the vehicle. The English Daewoo designers took a part in the development of the new cab and its interior, while Daewoo Avia specialist designers were responsible for the project co-ordination, and engine/chassis development. The new vehicle known as Avia D Series had its debut in the Czech market in the end of 2000. The major change that came along with the Avia D 60/90 Series vehicles was mounting of new self-constructed and self-produced engine titled as Avia D432.100, and Cummins ISBe 150 or ISBe 170 engine (England). The Cummins engine, with its more even speed-torque characteristic, has applied its advantage namely in more distant transports. Since 2002, the manufacturer has been offering two German ZF company’s gear-box types with the vehicles. Specifically, it comprises the ZF S5-42 five-speed gear-box or ZF S6-850 six-speed gear-box.
In the middle of 2000s the model range has been updated. The new models received new Cummins ISB4.5E5 Euro 5 engines with an output of 160, 185 or 207 hp. The updated model range has became much wider and includes the next models: D60 (GVW is 5990 kg), D65 (GVW is 6490 kg), D70 (GVW is 6990 kg), D75 (GVW is 7490 kg), D80 (GVW is 7990 kg), D85 (GVW is 8490 kg), D90 (GVW is 9000 kg), D100 (GVW is 9990 kg), D110 (GVW is 10990 kg) and D120 (GVW is 11990 kg).
