TaylorMade's Qi4D is one of the lowest-launching, lowest-spinning drivers we've tested—and that needs some unpacking
The latest robotic analysis was supposed to be a clean year-over-year look at TaylorMade's Qi4D lineup against Qi35 and Qi10. The headline was already half-written before the data came in, with Qi4D launching lower and spinning less than what came before.
But what pulled this piece open was the size of some performance gaps.
At roughly 95 mph, Golf Laboratories' swing robot noticed the standard Qi4D launched 0.8 degrees lower and spun 421 rpm less than its Qi35 predecessor at the same 10.5-degree static loft. The Qi4D LS dropped 440 rpm of spin in one cycle. Peak height on the standard head fell almost 14 feet. Carry distance was down by six to eight yards across all three models, but total distance largely held because the ball came out at a shallower descent angle and produced more roll.
For a 95-mph swinger eyeing the new lineup, that analysis could be a red flag. Low launch and low spin can benefit golfers with a positive AoA (angle of attack) and speed in the tank. But for golfers with a neutral AoA, those same numbers can put the ball on the ground earlier than expected.
That's where this analysis ended up, not just how much lower the Qi4D launches and spins, but whether the driver remains playable for the swing speed it'll most often be sold into.
Numbers at a glance
All averages are 54-shot robot-test results at ~95 mph club speed. Year-over-year deltas show how launch angle, spin rate, dynamic loft and peak height have moved since the Qi10 launch in 2024. Red numbers indicate where Qi4D delivers less than its Qi35 predecessor.

The shift TaylorMade engineered into the Qi4D is large enough to warrant pausing on the mechanism before the rest of the numbers make sense. Every other metric that moved this generation—lower launch, less spin, lower peak height, shorter carry—traces back to one decision at impact: how much loft the face actually delivers when it meets the ball.
On a 10.5-degree head, the Qi35 generation produced 19.1 degrees of dynamic loft at impact. The Qi4D produces 12.9. That's a 6.2-degree reduction in one production cycle on the same static spec, and it explains why nothing else in the Qi4D dataset looks like the lineup it replaced.
The standard Qi4D is the cleanest illustration. Ball speed and club speed essentially held, but flight efficiency suffered along the way, the predictable consequence of a face that delivers six fewer degrees of loft on the same swing.
The Qi4D LS family followed the same script with a bigger dip: 440 rpm of spin shed and 15.6 ft of peak height shaved compared to Qi35 LS, plus a 2.9 mph ball speed drop that pulled down overall efficiency.
The Qi4D Max, TaylorMade's high-MOI chassis, is often a good fit for mid-handicaps and slower swings, but it still gave back 153 rpm of spin and 8 ft of peak height versus Qi35 Max. The pattern is consistent across the board—low launch, low spin and lower peak heights—and the consistency itself is the tell. This isn't a head-by-head retune. It's a significant change in how the face delivers loft.
Launch and spin observations
Each driver plotted by its average launch angle (vertical axis) and spin rate (horizontal axis). The 2026 Qi4D family (squares) sits noticeably lower and further left than the previous two generations. This is the visual story of "low launch, low spin," and it's also why the Qi4D's ball flight looks different in the air.
Plot the nine drivers in the launch-and-spin plane and the picture gets even more interesting.
Compared to last year's Qi35 lineup, the Qi4D family pulls down and left. All three 2026 heads launch between 9.3 and 10.9 degrees and spin between 2,500-2,900 rpm, while the Qi35 trio launches between 10.1 and 11.5 degrees and spins between 2,900 and 3,100 rpm.
But the Qi10 generation didn't launch high either. The Qi10 LS sits at the bottom of the chart at 8.7 degrees of launch—lower than any Qi4D head—and the standard Qi10 and Max both land just below 10 degrees. The Qi35 LS at the top of the chart—11.5 degrees of launch, 3,110 rpm—looks like a different driver category from the Qi4D LS at 10.8 degrees and 2,670 rpm. It has an LS stamped on the head, but the launch and spin characteristics have been tweaked.
A 95-mph swinger optimizing for carry distance generally wants launch in the 10-to-14-degree range and spin in the 2,300–3,000 rpm range; that's a very conservative fitting window.
Read across the three generations, and the launch story isn't a one-way drop. All three Qi10 heads launched below 10 degrees. Only one Qi4D head does—the standard at 9.3 degrees—while the LS and Max both clear the floor.
The real generational shift is in spin. Every Qi4D head spins less than its Qi10 and Qi35 counterparts. That's where the flatter trajectory comes from, not from launch angle on its own.

The most useful thing to know about the Qi4D's flight isn't how much its peak height dropped; it's that the drop didn't show up in total distance the way it did in carry.
The Qi4D heads are reaching roughly the same finish line as Qi35, but the path they take to get there is meaningfully different. Lower trajectory, shallower descent angle, more rollout. That distinction matters for a real-world golfer in a way it doesn't for a robot.
A flatter trajectory rolls farther on firm conditions and stops shorter on soft ones. Carry sits closer to the variability a golfer feels on the course, while total distance is a function of conditions you don't control. The Qi4D is trading carry for roll, and that trade is more course- and weather-dependent than the lineup it replaces.
The numbers confirm the pattern. Standard Qi4D peaks at 55 feet versus Qi35's 69. Qi4D LS peaks at 63 feet versus 79 for Qi35 LS, a 14-to-16-foot apex drop in one cycle. Carry losses ran 6.5 yards on the standard, 7.5 on the Max and 8.1 on the LS. Total distance barely moved: 2.1 yards lost on the Standard, 0.7 on the Max, 3.1 on the LS.
Peak height observations
The Qi4D lineup reaches roughly the same total distance as Qi35, but the path is meaningfully different. Carry yardage dropped 6.5 to 8.1 yards. Total distance moved less than a yard on the Max, about three on the LS. The gap between those two numbers&mdashheld up by more rollout from a lower trajectory&mdashis the entire story of how the Qi4D produces its distance differently than what came before.
Instead of simply rehashing the numbers, we decided to see what would happen when the loft sleeve was utilized. Could it greatly improve launch conditions for those who might not be maximizing carry in the standard setting? The robot makes that argument testable.
Run the same 95-mph swing through 21 head-and-loft combinations across Qi4D, Qi4D LS and Qi4D Max with the sleeve at standard, plus one and two degrees, and the answer isn't a simple yes.
It's also not a no. The sleeve is doing exactly the job it's designed to do. Averaged across all seven head/loft combinations, moving the sleeve from standard to plus one or two degrees produces an extra 0.7 degrees of launch, 263 rpm of spin, 10.4 feet of peak height and 7.3 yards of carry.
Ball speed actually gains 0.7 mph in the process; the adjustment isn't costing energy transfer at this swing speed. The Qi4D's launch and spin shortfall, in large part, is a delivery problem rather than a fixed-head problem.
The 9-degree standard Qi4D is the cleanest illustration of how much that matters. At the stock setting, it produces the shortest carry in the entire test: a 40-foot peak, 1,978 rpm of spin, 212.2 yards of carry. Turn the sleeve up two clicks and the same head climbs to 54.3 ft of peak height, 2,314 rpm and 225 yards of carry, a 12.8-yard carry gain from a 30-second adjustment.
The 8-degree Qi4D LS picks up 12.4 yards of carry the same way. The 9-degree Qi4D Max, the highest-spinning of the Qi4D's lower-lofted heads, climbs from 51 to 66 feet of peak height when turned up.
But the bigger point is where the sleeve can't take you. Even with two clicks of additional loft, the 8- and 9-degree heads don't reach the optimal launch window for a 95 mph swing. Only four configurations land squarely inside it: the 10.5-degree Qi4D LS at every sleeve position, and the 10.5-degree Qi4D at plus two degrees. The lower-lofted heads in this lineup are built for speed and/or a positive AoA.
What the robot data tells us
TaylorMade engineered the Qi4D lineup to launch lower and spin less than what came before. The data confirms they did exactly that, and at a margin meaningfully larger than most year-over-year revisions deliver. For a 105-plus mph player who was over-spinning Qi35, that's a genuine win.
For a 95 mph player walking into a fitting bay, the picture is more conditional. The Qi4D head most likely to fit that swing isn't the standard or the LS at face value, it's the 10.5-degree Qi4D LS, which sits inside the optimal launch window at every sleeve position from stock through plus two degrees, the only Qi4D in the test that does.
The 10.5-degree Qi4D at plus two degrees gets there too. Everything else in the Qi4D lineup either underperforms the previous generation on carry distance at 95 mph or requires a swing speed that the average golfer doesn't have.
That's not a verdict on the driver. It's a fitting reality. The Qi4D is a playable driver for a 95-mph swing, but with one exception in the 10.5-degree LS, you have to fit your way into the launch window rather than sit there naturally.
The Qi4D delofts hard at impact, but the sleeve is what puts the loft back. Anyone considering this driver at 95 mph should plan on spending time with a wrench before deciding whether it works.
