Nissan claims the new Quest will offer more functionality and comfort without sacrificing space or driving prowess. That, and it will go on sale in early 2011. Beyond that, what we know is what we can see, and what we can see is that while the last Quest looked something like a puffed-up Versa, the new one looks to be based in part on the 2007 Nissan Forum Concept. Though more restrained than the Forum, the new Quest clearly cribs some of its front-end styling from the concept. The rest, though, will have to wait until the van officially debuts, likely sometime later this year.
