I have tried out the Felgen’s Sonett III with longitudinal FWD layout - I can’t install a 1.5 liter inline-4 (74.5 x 86 mm bore and stroke), it said “Engine is too big to fit in car”. The same problem also occurred when I tried to install a 2 liter inline-4 turbo in a corvette6317’s Delta.
I also updated the list of longitudinal FWD cars, because I misunderstood at first that B4 is the 4th generation, but it is really an updated 3rd generation (B3). Of course, all pre-1996 Audis (including DKW 3=6/F102/Audi F103 predecessor).
