The Development Division constantly seeks to manufacture new cars by developing next-generation technology and responding sensitively to ever-changing environment and lifestyle trends. The division pursues concept, styling and design in a quest to realize the ideal car. This persistent spirit of development is the source which gives birth to next-generation cars. The Development Division is responsible for planning and visual design which bring satisfaction to customers, as well as the technical design, testing and evaluation process which support the product appeal. These various functions are made possible by the teamwork of the division.

according to the measurement or the teardown investigation of
those to evaluate the performances or ease of use.

8. 2. DEVELOPMENT DESIGNING
2/13/2016 Compiled & Edited by Velmurugan Sivaraman 8
Carry out consistently the process of the concept making
through to the production drawing fix in conformity with the
corresponding vehicle concept.
The development designing department makes the basic
concept about parts/system’s specifications and performances,
cost, etc., reviews and makes drawings of the structure and
shape, and then fixes the production drawings consistently.
The development designing department makes drawings by
optimizing the structure and shape with the digital technology,
and then feeds back the test and evaluation results, etc. of the
prototype parts to seek higher quality and performances.
