Here you are a few shots from the final chase in THX 1138.
The dark blue and white cars (labeled "T6" and "H5") are modified Lolas T70 MkIII, although they were erroneously reported as Chaparrals in the past.
The motorbike is said to be a Triumph (some brightening needed to see the details).
Then you have a couple of cars still to be identified. Maybe Lolas too?

i listed out the green, white and red ones separately since they're all slightly different. then also listed the motorcycle. here's the link to check if i added them correctly:
