In both real world and rally who tests? In USA the emissions testing is what is called "self certification" which as explained to me by the Certification Engineer at Saab years ago means they send in data to US EPA and say "It does this" and that's it. Since I run a business that specialized in the Ford "Taunus" V4 which Saab used (1,5 liter for all markets from '67 thru 1980 except USA for 71 thru end or 73 when we got the "Big Block" 1,7 liter...) I asked about the use of 1,7 for the last 3 years of importation "what did you do about emissions" (the 1500 V4 was 90mm bore, and 58.6mm stroke and 9:1 compression, the 1700 was 90mm bore, same rods and 66.8 stroke and 8.0 compression...but same cam, same everything else)
In short similar stuff but really quite different, so I asked. He said "Oh we knew we're just schedule to sell those for 2-3 more years so we just sent in the same data as before..It is self certifying so why bother"
