I stopped by the Lemay Museum in Tacoma again this past weekend, and noticed some interesting aerodynamic features:
Nice solid wheel, not on a car you would expect:
How about this radiator shroud?
1954 Lincoln Capri!
1986 Owasso Pulse, claimed 100 mpg:
And, the Jetta Hybrid LSR car:
The class it ran does not allow modifications to the body, so no airdam, spoiler, or grill blocks:
But it still managed a 187-mph run on 300hp+electric motor. VW claims Cd .28 for the stock hybrid, but I can't find a number for this car.
