TaylorMade R540 XD. TaylorMade's 500 Series driver range comprises three models - the R510, R540, and R580. All are titanium. Using a two-piece face weld, the R500 Series' clubhead is composed of a high-strength titanium body and a cold-rolled titanium clubface. Manufacturing the clubface separately allows TaylorMade to make it ultra-thin yet extremely strong, so that it generates a more efficient energy transfer at impact, creating a higher COR. In 2003, the 500 Series won its third consecutive major championship when TaylorMade Tour Staff pro Mike Weir won the Masters using a R580. The TaylorMade R540 XD features a bigger head size and a longer, deeper clubface than the original R540. It also has an improved Inverted Cone Technology that provides a larger COR Zone, which equals higher ball-speed delivered by a larger area of the clubface.
