2 cars, both powered by Ford pushrod 5.0 engines. 1st one is highly modified with around 400 HP at the crank, 3.45s, 27 inch tall tire. Weight with me and a half tank is around 3400ish so figure 3100 empty. Second car is 100% stock running gear rated at the factory 225 HP at the flywheel, 3.27s, and a tire less than half an inch smaller. This car weighs about 6-700 pounds more. Car #1 gets about 8-9 more mpg at highway speeds.

At highway speeds, aero drag matters much more than weight does.

I think at 55 the weight is still a very significant factor. Besides, 1987 Mercury Cougar vs 1990 Lincoln Mark VII. It's not a Countach vs a RR Corniche.

Generally aero drag equals rolling drag around 35 mph and rises with the square of speed, so there's much more aero drag at 55 than rolling drag. But you're right, those cars are similar in the aero department.
Engine mods done right will pay off in both power and efficiency.

Yep, car #1 allows for taller gearing at that speed as well. All the little things add up.
