I like to call it the Tumbler b/c that's what Lucius Fox named it in the script.
Anyway, looks interesting, and cool to finally see it moving and everything. The design for the vehicle is still freaking hideous and butt ugly. Also get a look at the Gotham City Police Department cars, they look a lot like modern generic cop cars.
One thing I did notice, it looks like the car chase is being shot without any CG or blue/green screens. It really looks like Christopher Nolan is serious about shooting Batman practically with little or no computer graphics at all.
