While this isn't racing data, I did check fuel economy with the top up and down
on a road trip to a VTR Convention in my TR6 . With it up, the mileage went up
4 mpg. I attributed that to better aerodynamics with the top up, but that's
just an uneducated guess on my part.
I was also able to observe that a TR4 will lose 500 rpm on the straight at Road
America if the trunk lid comes up and stays up, but that's another story.
