as the guys have said ,, Renault sport used the ph1 in 4x4 form in the french superproduction 1988,,and supertourisme 1989 championships,, they were racing bmws, mercs,peugeots, porches, chevys etc,, they won the title in 1988 with ragnotti driving(grey car in above pics),, and came second in the 1989 title with bousquett driving,(red cars)
additionaly i found out today that a privateer entered a 21turbo into the 1990 and 1991 supertourisme championships, and i reckon from the pic i have of it that it must be teos car(which i thought was just someones very expensive replica)
renault sport also ran their own "europacup" versions in their own series which as dave said, they ran before a few of european f1 and truck racing meets similar to the cliocup series and WSR by renault today
during the early 90's a few privateers bought the ex europacup cars and ran them in various saloon championships in europe such as the Belcar series in holland/belgium, and some entered road style rallies
also renault turkey ran 3 europacup cars in turkish touring car championships at the same time renault had the europacup series in europe
also our very own bob claxton still races his europacup in the northen saloon car championships in the UK, another guy in holland races his over there, and a custom made europacup/quadra still races in belgium
a few were also used in various rally championships but not very successfully, a few still rally today
chris klinkert one of our members has a grpn car that won the manx rally again in the early 90's
lastly, two cars were built to attempt to break the world speed record on ice and broke the record making approx 155mph on ice,,(this has been broken since)
the superpros are all in the museum, along with 2 europacups, the ice record car, and a few grpn/a cars
theres about 20-25 europacups that i know of around europe
