If gas prices continue in the direction they're going, it won't be long before Americans begin demanding vehicles like this little space wagon concept, which made its international debut in Geneva. The fifth concept vehicle presented by Mazda in the last six months, this six-seat people mover is built on architecture borrowed from the all-new Mazda3 platform. Powered by the same transverse-mounted 16-valve 2.3-liter/169-hp MZR engine found in the Mazda3 and Mazda6, its four-speed Activematic transmission can be operated in automatic or pseudo-manual modes. The bright cabin was designed to balance utility, comfort, and quality, and is accessible via dual sliding doors that open to three seating rows, each with two individual leather-wrapped captain-style chairs. For flexibility, the second- and third-row seats easily fold away to provide a nearly flat cargo floor. While it is labeled a concept, Mazda hints that it could be the foundation for a future space wagon. The fact that we're seeing it again stateside hints that might be ready for production.
