A 4 stroke of 150HP usually only gives 135HPmax at the wheels, times the gear ratio.
Eg: if you have an overdrive gear ratio of 0,97:1 as 4th gear, being closest to a direction drive, and 134HP at the wheels with a direction drive, your car is only getting the performance of a 130HP at best. In 6th gear, if your gear ratio is 0.75:1, you're essentially only getting 97.5 HP in final gear, from a car which engine gives 150HP.

Yes I understand the concept of what you mean as I'm engineering (gear reduction and efficiency), but your not gonna need more than 20-30 hp to maintain 70. Horsepower to overcome drag at 80 mph would be around 40% more which still would only be like 1/3 throttle.
Also EVs still have gear loss its just minimized since they only have a final drive system forgoing the transmission unit. So no free cake here.
