The 2009 Pontiac Vibe will be officially unveiled at 4:00PM EST today during an event called the Vibe Slam. You can watch the live reveal here, but we're on hand in person and will bring back all the material info on Pontiac's new people mover for your perusal. Of course, one could argue that the Vibe was debuted last week at SEMA when Toyota debuted its essential clone, the Corolla Matrix. In fact, aside from appearances, there appear to be hardly any mechanical differences. Returning to the Vibe lineup after a hiatus is an all-wheel-drive option and the GT model. Unfortunately, coupling a power-sapping all-wheel-drive system to the car's tiny top shelf engine, a 154-hp 2.4L four-cylinder, is a recipe for the antithesis of excitement. We'll bring you more official info after the car is unveiled at 4PM, but until then you can watch the 2009 Pontiac Vibe motor along on video thanks to a few clips that snuck onto YouTube early.
