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.
Although diesel cars obtain 25 to 35 percent better mileage and emit less carbon dioxide than similar gasoline cars, they can emit 25 to 400 times more mass of particulate black carbon and associated organic matter (soot) per kilometer [mile].
