The Z4 Roadster is now available with a revised folding hard-top for greater ownership enjoyment. Engineers in Munich have enhanced the elegant two-piece folding roof with a reinforced hydraulic system so that it can now be raised or lowered at speeds of up to 25mph. Previously the roof could not be lowered while on the move.
The Z4 is offered as an sDrive 28i, sDrive 35i, and perhaps the sleeper of the BMW range, the sDrive 35is. Next year we should see the Z4 get it’s mid-cycl refresh (LCI) with updated bumpers and taillights expected on the outside and a slightly refreshed interior.
