It takes approximately 20 to 30 HP to keep a car with good Cx moving at a constant 65MPH in calm air
Our TV's with brick like Cx, guessing would be about double at around 40 to 60 HP required
Engineer's know this and design to the best portion of the ICE's torqure/HP spots for each gear...and another why of todays many more gears in automatic trannies
Plus, ICE's have low fuel efficiency (gasser about 25-28 percent and diesel about 40 percent) , so there are many potential improvements
