DSM/Car Design

1G

...Mitsubishi handled most of the interior design and basic engineering. Chrysler did most of the exterior design.

^[1]

The credit for the design of the cars is still debated today. Both companies claim credit for different design areas. It is a fact that the DSM line is based on a shortened version of the front wheel drive Mitsubishi Galant.

Incorporated into the Diamond Star Motor cars are Galant engines, gearboxes, and suspension pieces. Mitsubishi handled virtually all of the engineering and was also responsible for the cars' interior design. It is hard to say for certain who created the sporty design of the 2+2 seater. Designers from both Chrysler and Mitsubishi were involved in all phases of the styling process, but the two companies disagree about the amount each contributed. It has been pointed out that the original, full-size clay model was produced by Chrysler's West Coast Pacifica design studio. The front bumper and air dam were created from a model submitted by Mitsubishi's California design firm.

Chrysler`s version of the sporty Diamond-Star hatchback coupe was designed in Highland Park, Mich., but uses engine, transmission and other mechanical components supplied by Mitsubishi.

 The '95 Eclipse is the result of a design competition between the Mitsubishi Motors America (MMA) Design Studio in Southern California and a design team at Mitsubishi Motors in Japan.

The U.S. team won.

The goal was to bring to market an affordable high performance sport coupe with advanced safety and handling features. The winning MMA design team consisted of Amy Horoshige, who was born in Hawaii, and Dragan Vukadinovic, who was born in Yugoslavia and raised in Cleveland, Ohio.

"I was thrilled when MMA was selected," says Hiroshige. "'The Eclipse is my generation's car, for my generation's market. I could literally design this car for myself!"

CAD (Computer Assisted Design)

The first generation "Three Sisters" very well could have been designed from the ground up first using Technical Design Computer Software. However, there has been little to no documentation of this released to the public. Figure 11-0.1 of Technical Drawing 12th edition^[5] gives up many hints however, so we shall start there.

The image includes two workers from DSM (they are both wearing the DSM uniform, button-up shirts. The DSM logo and worker's name visible on one of the worker's shirts.)

The workstation they sit at is an IBM RS/6000, type 7012, model 3XX/300 series workstation^[6]. For completeness, the keyboard appears to be an IBM Model-M, the monitor an IBM ??, and finaly the digitizing tablet IBM???.
