I wouldn't be surprised if Lucas had a new landspeeder built and reshot the scene for the SE. The curve of the windshield is different and it goes back farther towards the actors' heads. There's an indent on the back of the engine nacelle in the 1977 shot that is not there in the SE shot.

Maybe it really is a different take from the 1977, just from an angle a little different so that different details showed up. But my theory is it's a reshoot.

The 1977 shot was a pickup done at the last minute in the California desert with doubles for the actors. So Lucas would not have a problem doing a reshoot, I think.
