Design
The Cimarron used the front-wheel drive GM J platform with a 101.2 in wheelbase. Employing unibody construction, the suspension, which was calibrated with GM's "F41" suspension, used front MacPherson struts which were mounted to a subframe, lower control arms, coil springs and a stabilizer bar, while a torsion-beam rear axle, along with rear stabilizer bars, was shared with the Buick Skyhawk and Oldsmobile Firenza and was borrowed from the GM X and A platforms.[11]
To distinguish the Cimarron from the Chevrolet Cavalier and its Buick, Oldsmobile, and Pontiac counterparts, Cadillac standardized many of the available features offered on J-platform cars at the time. The listed retail price for 1982 was $12,181 and the standard equipment were air conditioning, additional sound insulation, Trianon deep-pile carpeting including the trunk, aluminum alloy wheels on steel-belted radial tires, twin power adjustable side view mirrors, leather-wrapped steering wheel, full instrumentation including tachometer (the only Cadillac to have this at the time), courtesy lights, intermittent wipers, rear window defogger, and AM/FM stereo.[11] Its interior featured simulated aluminum trim, notably initially foregoing simulated wood trim, which was added in later years with appearance updates. Leather was offered for the upholstery and door panels only in the Cimarron, and the name "Cimarron" was embroidered on the seatback surface. Digital instruments were offered in 1986 along with Touch Climate Control air conditioning, and a leather and faux suede upholstery option was later offered.[12][13] The dashboard assembly was shared with the Cavalier and the Sunbird, while the Firenza and Skyhawk shared an entirely different design. Twilight Sentinel and fog lights were added as standard equipment in 1983.
Available options for 1982 included automatic transmission for $370, cruise control for $155, tilt steering wheel for $88, power windows for $216, power door locks for $12, power driver and passenger seats for $366 for both, Vista Vent with rear tilt sunroof for $261, and a choice of a cassette player, $153 with a separate choice offering a CB radio for $560.[12][13] Additional convenience and appearance options available were twin lighted vanity mirrors for $92, power trunk release for $29, door edge guards for $22, license plate frame for $12, trunk lid luggage rack for $98, carpeted floor mats front for $38 and rear for $22, trunk mat for $18 and whitewall tires for $55. With the exception of its upholstery and model-specific special suspension tuning, J-platform sedans from other GM divisions could be optioned nearly identically to a Cimarron, though doing so would raise prices close to the Cimarron's base price.[6]
Powertrain
For 1982, the Cimarron was equipped with a Chevrolet-built 1.8 L four-cylinder engine, producing 88 hp (the first four-cylinder Cadillac since the 1914 Cadillac Model 1914 and the first engine below 2.0 L displacement since 1908). For 1983, the engine was enlarged to a Chevrolet-built 2.0 L and given throttle-body fuel injection, though engine tuning would drop peak output to 86 hp. For 1985, a Chevrolet-built 2.8 L V6, which was shared only with the Chevrolet Cavalier coupe and Oldsmobile Firenza hatchback, was added as an option, producing 130 hp; the V6 became the standard engine for 1988 but was not available in the Cavalier or Firenza sedans. Both engines were paired with a four-speed or five-speed manual depending on model year, with a three-speed automatic as an option, shared with other division vehicles.
