I'd be reluctant to burn him at the stake.I ran the T-100 on the stretch of 80-mph interstate out in W.Texas between Monahans and Van Horn.She was still pulling over 31-mpg,and that was with hilly terrain. And at 100-mph airspeeds at 80-mph road speed she only dropped to 28.The Bimmer may be hitting it's stride there at 80.Don't know.BSFC is a funny thing!If someone can get the max.torque rpm and the gearing for that car,we could probably learn something.
