How Much Horsepower Needed to Cruise?

This not exactly the subject topic line I wanted to use, but needed to keep this from looking too off-topic.

At lunch, someone was mentioning someone with a go-cart could go 78 mph with a 5.5 horsepower 2-cycle engine. That got me thinking about a couple of things:

- How much horsepower does the Insight need to cruise at 50, 60, 70 mph?

- How much lighter can the Insight be made? I know the Insight2 concept car is about 1500 pounds, 300 less than the Insights on the road.

The actual HP depend on the car. A smooth EV1 or Insight would be <20. A brick-shaped SUV is likely 30 hp.

As for the go-kart, I can believe 5.5 hp = 78 mph max. It's low to the ground with minimal resistance.

Likewise VW's 240 mpg car can go 60mph with only 4 hp @ 2000rpm -
