Sprinkled around Cobo Hall this morning in the wee hours of the 2011 Detroit Auto Show, we discovered a number of promotional images from Toyota teasing the big Prius announcement that's coming later this afternoon. We don't know with 100 percent certainty, but the ad sure makes it look like the secret Prius concept to be unveiled later today will be, ta da!, a smaller Prius hatchback.
From what we can gather, the diminutive hatch will officially be unveiled in a few hours, but we thought the new Prius family line-up – featuring (from left) the Prius Plug In, the Prius MPV, the standard Prius and the new hatchback – was worth sharing. Stay tuned for live pics and the full details once we're back form the Toyota press conference. Until then, discuss if you'd like to go for a spin in the smallest version of the world's best-selling hybrid.
