The Chevrolet Spectrum was a rebadged version of the Isuzu Gemini, sold by Chevrolet in North America from 1985 to 1989 as part of a joint venture. The production of the Chevrolet Spectrum began with rear-wheel drive until developers changed it to front-wheel drive using the T-Car framework. The PF50 chassis designation applied to the original model and PF60 appeared with the 1.8L version while the PFD60 specified the diesel version. Following its Chevrolet Spectrum rebadge the Sohc carbureted engine model of Gemini gained a diesel version by 1983. The first generation Chevrolet Spectrum had dimensions of 4,135 mm in length and 2,405 mm wheelbase that evolved to 2,619 mm wheelbase in the fifth generation. The manufacturer supplied customers with manual gearboxes in addition to automatic transmission options. The Chevrolet Spectrum displayed agile handling because its lightweight structure amounted to a curb weight of around 930 kg. Genuine Chevrolet Spectrum parts availability became a prominent marketing point to let vehicle owners preserve their car performance from factory specifications through proper maintenance.
