When introduced, the Shelby CSX was touted as having a near-perfect blend of raw power and road performance. The 1989 Shelby CSX provided the evidence that the Shelby performance ideal was still quite alive and kicking. This model would represent the final type of Dodge Shelby produced. Production was limited to 500 vehicles (including two prototypes) and with the completion of these cars; Carroll Shelby's direct involvement with Dodge was complete, although he continued to work on projects with Chrysler. This was often in the form of taking advisory roles, which included the development of the Dodge Viper and Viper GTS.

The engine was the main point of appeal in this model of car. When setting out to design a true road machine, this component is generally the starting point, and the Shelby CSX was no exception. Beneath the hood is an intercooler-equipped 2.2-liter four-cylinder engine, featuring a variable-nozzle Garrett turbocharger. The turbocharger unit was described as providing a V-8-like response, virtually eliminating any turbo lag. This unit is paired up to a five-speed Getrag gear-set that allows the CSX to accelerate “off the line like a rocket.” With a 175 horsepower rating, the CSX is able to cover the 0- to 60-mph run in less than seven seconds, with a top speed of approximately 135 miles per hour. With performance numbers such as these, the CSX was able to out-perform certain performance coupes that cost two to three times as much.

The CSX is prepared in a manner that is not based on engine performance and straight-line speed only; the Chrysler-based CSX is also equipped with a special Shelby suspension system. Four-wheel disc brakes, coil springs, dual anti-sway bars, Monroe Formula GP shocks and struts, 15-inch Goodyear Gatorbacks and Shelby sport composite wheels (“Fiberide” presented in gold-tone) combine forces to make the handling experience predictable and fun.

This red example has a gray interior that features bucket seats and a center console. Factory aerodynamic elements are seen with front and rear spoilers, plus aero-inspired skirts between the front and rear wheels. The CSX is said to be like-new and still has the plastic covering on the seats and steering wheel, plus records show the mileage as actual. The stickers have never been removed, including the window sticker. This era of Shelby involvement reflected his thrill and desire to see the driving of a high performance vehicle become an affordable experience.
