Here's a half-baked idea for a 15HP diesel engine: you could do a gasoline/diesel hybrid. Have the engine drive a fifth wheel located beneath the cargo floor of your Civic wagon. Use the gas engine when you need to go 0-60 in less than a minute, and use the diesel for cruising. It's a poor man's cylinder deactivation / bi-fuel scheme.

However, 4.5HP will give NEV-like performance in any road car. 40mph, tops. 0-30, eventually.

In order to achieve highway speeds, you're going to need a streamlined, two- or three-wheeled vehicle, preferably under 500lbs.
