Rory McIlroy and Aldrich Potgieter are tied at the top of the PGA Tour's driving distance chart. Both average 330.3 yards, according to Golf Monthly's October 28 breakdown, taken before the Mexico Open. That is about 24 yards past the Tour average.
They got there with different drivers. McIlroy plays a TaylorMade Qi4D. Potgieter plays a PXG Lightning Tour Max. Look down the rest of the top 10 and no two players share a driver head.
If one club were the secret, the ten longest hitters in the world would have found it. They haven't. That tells you where distance with driver actually comes from.
The PGA Tour's 10 longest drivers and what's in their bags
| Player | Avg. drive (yds) | Driver |
|---|---|---|
| Rory McIlroy | 330.3 | TaylorMade Qi4D |
| Aldrich Potgieter | 330.3 | PXG Lightning Tour Max |
| Michael Brennan | 327.0 | Titleist GT3 |
| Nicolai Højgaard | 325.1 | Callaway Quantum Triple Diamond Max |
| Marco Penge | 324.7 | PXG Lightning Tour Mid |
| Rasmus Højgaard | 323.0 | Callaway Paradym Ai Smoke Triple Diamond |
| Chris Gotterup | 322.9 | Ping G440 LST |
| Min Woo Lee | 322.4 | Callaway Quantum Triple Diamond |
| Gary Woodland | 322.2 | Cobra OPTM Max K |
| Jesper Svensson | 321.8 | Titleist GTS4 |
That is six brands and ten different heads. Even the Højgaard twins play different Callaways.
Golf Monthly's own explanation for the distance points away from the clubhead. It credits gym work and technology, and says these players fine-tune their spin and attack angle to get the most from the speed they have. The driver is a fitting decision at the end of that chain, not the start of it.
How to gain distance with driver: the three numbers that matter
Every drive comes down to the same three things. A launch monitor measures all of them.
1. Clubhead speed sets the ceiling
Clubhead speed is the single biggest input to how far the ball can go. A perfectly fit driver can't make a 95 mph swing hit it like a 120 mph swing. The Stack System's own data puts it at roughly 2.7 yards of driver distance per mph gained.
2. Strike turns speed into ball speed (smash factor)
Smash factor is ball speed divided by club speed. A centered strike transfers the most energy. A heel or toe strike leaks yards before the ball has even left the face. For a lot of golfers, this is where the easiest yards are hiding.
3. Attack angle, launch and spin decide what the ball does with that speed
Too much backspin and the ball balloons and drops. Too little and it falls out of the sky early. Attack angle with driver is a big part of this. Swinging slightly up through the ball lets you launch higher with less spin. Swinging down on it does the opposite, which is why "hit down on it" is the wrong thought with the big stick. The better picture is swinging through and past the ball, not chopping at it.
This is where a driver fitting earns its keep. A different head or shaft can tune launch and spin. It cannot add speed you don't have, and it cannot fix a strike that wanders across the face.
What to do before you buy a new driver
Find out which of the three numbers is costing you. Then work on that one.
Measure first
You can't train a number you've never seen.
- Stack Radar is a portable doppler unit that reads swing speed, ball speed, estimated carry and smash factor. It also reads swing speed with no ball, which matters for speed training.
- FlightScope Mevo Gen2 goes further: spin rate, spin axis, launch angle, angle of attack and spin loft, plus video of every shot. Indoors, spin readings need the included metallic stickers or Titleist RCT balls.
Then train the ceiling
If clubhead speed is the limit, speed has to be trained on purpose. It doesn't arrive from hitting more balls at the range.
- TheStack Speed Trainer is a weighted training club with five stackable weights and app-guided programs written by biomechanist Dr. Sasho MacKenzie. It needs a speed radar to train with, sold separately.
- The TheStack + Stack Radar bundle puts both in one box.
- The Stack reports an average gain of 10.1 mph across its users. That is a company average from people who did the programs, not a promise for any one golfer.
2022 U.S. Open champion Matt Fitzpatrick has credited TheStack for his own speed gains. Our post on how Matt Fitzpatrick sharpens his iron play covers the other side of his practice.
Then think about fitting
Once your speed and strike are where you want them, a fitting can tune launch and spin around them. In that order, the fitting is worth far more.
Common questions
Does a new driver add distance?
It can, if your current driver launches or spins badly for your swing. A fitting fixes launch and spin. It won't add clubhead speed or fix off-center strikes, and those two usually hold more yards.
What driver does Rory McIlroy use?
McIlroy plays a TaylorMade Qi4D with a Fujikura Ventus Black 6 X shaft, according to Golf Monthly. He moved into it at the end of 2025.
What driver does Aldrich Potgieter use?
Potgieter plays a PXG Lightning Tour Max with a Fujikura Ventus TR Black 7 X shaft. He signed with PXG in January 2026 after using Titleist.
What is a good smash factor with driver?
The ceiling allowed under the equipment rules is about 1.50. The closer you get, the more of your clubhead speed is reaching the ball. Track it on a launch monitor rather than guessing from feel.
The takeaway
The ten longest hitters on Tour agree on almost nothing about drivers. They agree on speed, a centered strike, and launch conditions dialed in to their swing. Those are trainable, and measurable at home.
In December we're publishing a full swing speed chart: what speed you need for each carry distance, and how to train toward it.
