Background:
Plymouth XNR
- XNR is named after its designer – Virgil M. Exner (XNR = Exner)
- Ghia in Italy pounded out the body
- It was released for the Show circuit in 1960
- The color was Red
- It was powered by a 200HP Six-Banger.
- The 1961 Valiant looks to have some of the styling cues of this car – especially the trunk lid (less the fin) and size.
- It was being built during the time when Exner was frustrated with what was happening to his 1963 designs.
History:
Far offset position of the hood scoop suggests that the XNR may have been equipped with "Hyper-Pak" long ram 4-bbl. intake and ductile cast iron split exhaust (it is known to have had dual exhaust). The street Hyper-Pak used a re-jetted Carter 2948S AFB and generated 194 horsepower. In a 1960, 30-mile compact car race at Daytona Beach (televised nation-wide on CBS, sponsored by Chevrolet), Hyper-Pak Valiants took 1st through 7th place, defeating all Falcon and Corvair challengers. First place Valiant driver Marvin Panch's average speed was 122.282 mph.
Other Valiant-based concept cars: Chrysler 250 (Ghia body, Chrysler built), Asymmetrica (Ghia body, but not built by Chrysler, "St. Regis" (Ghia body, but not built by Chrysler). Then, of course, there was Tex Smith's, Steve Swaja-designed, "XR6" which was built by Barris Customs, Gene Winfield, Gordon Van's Body Shop and Smith himself. This car was cover feature of August 1963 HRM (on which it is pictured parked next to an F-104). This car was slant-6-powered and featured triple Weber DCOE side-draft carbs.
Technical:
Body was made by Ghia.
