Many of the Pokmon within the Dream World will have abilities that the Pokmon you transfer over from Diamond, Pearl, Platinum, HeartGold & SoulSilver don't normally have, such as Vaporeon with Hydration and Glaceon with Ice Body. A few are also available in-game and others through events.
Hybrid cars have smaller, more efficient internal combustion engines than conventional vehicles because the electric motor provides additional power when needed. The smaller engines produce less pollution. Gasoline engines in hybrids automatically shut off when stopped and restart when the accelerator is pressed.
A hybrid car is a car that uses two or more sources of power. The most common type of hybrid car is the gasoline-electric hybrid car, which is powered by a gasoline engine and an electric motor.
