The biggest, baddest Rolls-Royce will soon be here. We've seen spy shots the new Cullinan for months , but this is our first look at the SUV's interior. Though much of it is still covered, we can make out a few details hiding beneath the surface. There's no word on when the new Rolls will hit the streets, but look for a debut sometime this auto show season.At first glance, there seems to be a lot of parts taken straight from a BMW parts bin. BMW owns Rolls, so this shouldn't be too much of a surprise. Still, it's disappointing to see the steering wheel from a 3 Series in place of the handsome, thin-rimmed wheels you usually find in a Rolls-Royce. That said, this could simply be a temporary solution while the car undergoes development. The rest looks a lot like the new Phantom . This includes the digital instrument cluster and various switches and knobs.There really isn't anything new we can glean from the Cullinan's exterior. We've seen this all before. The rear doors are of particular note as they each appear to have two door handles. Look closely and you can see a regular one in the back and what appears to be another up front. The latter suggests it may have suicide doors, though it may simply be a trim piece meant to simulate that iconic Rolls feature. We'll have to wait for the full debut to find out more.
