In 1990, Chrysler released their Dodge Daytona IROC RT concept vehicle onto the auto show circuit.  Although the concept was not exactly the same as the Daytona that would be sold to the public, many of the design elements of the concept would appear on the 1992-1993 Daytonas, such as the fixed headlights, rounded, one-piece taillamps, the cross-hair grill, and the more fully integrated side ground effects.  Under the hood was a single overhead cam, turbocharged, VNT 2.2 liter inline-4 cylinder.  The variable nozzle turbo (VNT) engine provided full turbo boost in only 2.2 seconds.  The claimed performance was 0-60 in 6.1 seconds, with a top speed of 140 mph.  The suspension was independent in front, with a trailing-arm in back.  The tires were P275/40VR17 Goodyear Experimentals on 17 X 9.5-inch cast aluminum wheels.  Two design elements that were on this concept car that never made it into the production vehicles was the all glass roof, and the all-wheel drive system.
