From the Manufacturer

This year, M2 driver also comes in a D-Type variant, which features a draw-biased design to help golfers eliminate a right miss and gain more distance with a straighter ball flight. The D-Type driver (“D” representing draw) combines multiple draw-biasing design technologies to deliver an average of 12 yards—and up to 20 yards—of built-in draw-bias to help players who consistently fight fade-to-slice trajectories find more fairways. In addition to the multi-material construction, a Geocoustic sole, and an active Speed Pocket, the D-Type is more heel-weighted, has slight offset, and uses advanced visual cues to promote a square face at address and a more draw-biased face at impact.
