It does not have VR. It does, however, contains more lens elements. Weight reduction is probably down to outer material being plastics as well as plastic moulded lens elements.

I doubt very much a lens of this quality has plastic moulded lens elements. Optical properties of plastic aren't as good as glass yet. The weight savings are purely due to the use of lighter materials in the barrel.
Kind regards, Wim
