Diamond Star Motors Heritage:
A joint venture between Chrysler and Mitsubishi Motors, established in 1985. Diamond-Star Motors (DSM) primarily manufactured Mitsubishi-designed vehicles for both the Mitsubishi and Chrysler brands in North America. The platform used for the Laser, Talon, Eclipse, and Galant is a testament to this collaboration.
First Generation:
1989-1994. Featured distinctive styling, front-wheel drive and optional all-wheel drive. The turbocharged GS-T and AWD GSX models were performance benchmarks. The Chrysler Laser was a rebadged Mitsubishi Eclipse.
Second Generation:
1995-1999. Significant redesign with more aerodynamic styling. Offered naturally aspirated and turbocharged engines, with AWD remaining a key option. Mitsubishi Eclipse and Eagle Talon were largely similar, while the Chrysler Sebring Coupe replaced the Laser in Chrysler's lineup for the latter part of this generation.
Production Location:
Normal, Illinois, USA (Diamond-Star Motors plant)
Performance Awards:
The Mitsubishi Eclipse GSX and Eagle Talon TSi AWD were frequently lauded in automotive magazines (e.g., Car and Driver, MotorTrend) for their performance and value in the sport compact class during the 1990s.
Sport Compact Rankings:
Consistently ranked among the top affordable performance cars of their respective eras.
