No one said anything about putting in a bigger motor. Just leave the puny 1.0 litre 67 horsepower motor in there. The weight reduction of removing the hybrid system will result in a greater horsepower to weight ratio anyway. The elctric motor produces 6 horsepower, not 7 hehe. So replace nothing, just remove the electric motor and its battery pack. What would the car weigh then? What would its horsepower to weight ratio be then? Interesting questions. Maybe in a few years when I can afford a 2000 Insight with 160,000 miles I'll buy one and when the battery in it dies, I'll try it! And remember, there's always engine off coasting and bump starting.
