Driving the Volt under gasoline power is a lot like driving any other gasoline-powered car. When you step on the gas hard, demanding a lot of power, the gasoline engine revs up to supply it. When you let off the gas, it slows back down.
The biggest difference between a gas-power versus an electric-power car is that there's no transmission. Electric motors don't need gears or gear shifts.
