These cutaways are really popular; the carmakers like to show us the flow of blinky lights from the brakes to the batteries to the motor and engine. Here's the new 2007 Saturn Vue hybrid. At 27/32 (city highway), it gets better highway mileage than the Escape hybrid, but worse city. I wondered why the Saturn girl said "It is the world's most efficient SUV on the highway." Notice in the background that distinctive "H" hybrid symbol. GM has chosen a very prominent marker for its hybrid lines.
