Both the 2017 M1 and M2 drivers use a new aluminum loft sleeve, in replace of the existing plastic loft sleeves the company used. The switch to aluminum makes the loft sleeves more durable for club fitters.
The new M2 D type drivers are specifically designed to help students who slice the ball. This club is designed for a little more spin and 12 yards of draw bias.
The 2017 M2 driver has a more rearward centre of gravity that tends to cause drives to fly with excessive spin. To reduce it, TaylorMade made the M2’s Speed Pocket, a slot located on the front of the driver’s sole, three times more flexible than the original model. It also helps improve ball speed on off-center hits, a phenomenon known as “effective Moment of Inertia.”
The M1 440 is designed for golfers who prefer a smaller, more workable driver than the M1 460. It’s said to hit drives with approximately the same launch angle and spin rate as the M1 460, but initial testing proved that it can reduce spin by several hundred rotations per minute. The smaller size of the M1 440 allows TaylorMade to increase the weight in the front-back weight track of the driver to 15 grams, making each of its T-Track weights 15 grams.
