The late 90s was short of a peak of light weight and aerodynamics. Often at the cost of safety to some extent. The insight was one of the lightest and slipperiest. But it had a heavy battery pack (now removed) that was used as a power booster for the ICE. EPA was 53mpg which was good for the time.
This guy basically built a DIY VW XL1. Except he did it with 30% 100cc less displacement and no restrictions on emissions.
The XL1 got 240mpg for reference, 73 should be way to get and he could probably do way better with a tank of engineers and things like start/stop that the VW team had.
Edit: I was thinking the VW was a 1 liter but it’s 800cc.
