CAR Magazine has pictures of the Opel Meriva Concept, a U.K.-only car with a brand-new door system. You may notice that this car looks awfully like the Saturn Flextreme we posted about yesterday—which makes sense, since Saturn has morphed into a way to buy Opel vehicles in the U.S. At any rate, the Meriva Concept features the FlexDoor system, which appears to be a combination of conventional front doors and rear-hinged rear "suicide" doors.

"Unlike the similarly apertured Mazda RX-8 - where the two doors interlock to close, eliminating the B-pillar--the B-pillar remains," the article said. "But that's not to dismiss it--the Meriva's doors are actually an ingeniously simple solution for families and the elderly. Conventional rear doors separate front and rear passenger compartments when they're open, making it hard to load children into the back. They're also difficult for the elderly. The Meriva solves the kid problem, while a handle on the B-pillar allows the less mobile to lower themselves backwards into the car."

Other features on the concept include a variable-height trunk floor, new hatch and rear door glass that "maximizes visibility" — how exactly do you improve on clear? More Windex? — and a nifty panoramic roof that's split in two by a central steel beam.
