Lynne: Here is the technical answer:

"This question really has no answer. Displacement (liters) and horsepower are two completely different types of measurements. Displacement measures how big the engine is, and horsepower measures the power output. A bigger or smaller engine doesn't mean more or less power."

But let's talk about fuel consumption. Basically, the larger the displacement, the more fuel required to move the pistons (this is over-simplified, of course, because many other factors control horsepower AND fuel consumption). But for example, my 1969 VW bus had a 1.2 Liter engine and did pretty well with probably under 90 hp. The 2013 Prius has:
1.8-Liter Aluminum 4-cylinder DOHC 16-Valve with Variable Valve Timing with intelligence (VVT-i), EV [1]/ECO/POWER Modes; 98 hp @ 5200 rpm

You can always get a Ford F-250:   385  hp @ 5500 rmp (6.2L V8) 

but the only reason you need it is if you own a construction business and regularly haul thousands of pounds of materials.... or you just want to show off!

Just because you can drive 35 miles on an overnight electric charge does NOT mean that the vehicle is "environmentally friendly.

How many horse power in a liter ?  Liters do not mean much to me they sell 2 liter bottles of Pepsi and the engine is a 3.5 liter . .  Not much of an engine !
