Hadn't looked at it that way, but don't think so. The 'silver car' Esprit prototype debuted in 1972, this car is circa 1979. It basically resembles every other Grp 5 running at the time.
In the bottom picture, if you squint you can see the Europa shape in the roof-line and windows/greenhouse.
I have a couple slot cars of this (and just about every other Lotus)
I didn't know this Europa based car ran into the 1980's.
