Just by looking at the 1/X concept (pronounced "one-Xth"), it’s not difficult to make a connection with the Prius. However, despite what you may think, the 1/X is not actually previewing the next-gen Prius but a smaller hybrid expected to go into production in 2011. We talked to At 3,900 mm long (153.5-inches) the 1/X is 545 mm or 21.5-inches shorter than the Prius but according to
The 1/X is equipped with a mid-mounted plug-in hybrid powertrain with a displacement of just 500cc (0,5-litres) that allows charging from an external power source and a longer electric-motor cruising distance. And guess what people; the 1/X is rear-wheel drive! Now if that’s not good news, we don’t know what is! Well, maybe that the 1/X's fuel consumption is about two times better than the Prius, but we'll stick to the mid-mounted, rear-wheel-drive layout.
