The Callaway Quantum Triple Diamond (TD) driver arrives with a clear intent: to reclaim Callaway's dominance at the top end of the better-player driver market.
After a somewhat quiet year where the Elyte family struggled to gain widespread traction, could the Quantum TD offer a return to form with its tour-inspired, compact 450cc head built for speed, workability, and a penetrating flight?
I’ve been testing this new offering extensively to see if the next-gen of A.I. optimization delivers the performance better players demand and position the Quantum TD among the best golf drivers in the game…
The Quantum TD is built around what Callaway is saying is a breakthrough Tri-Force Face. This technology layers ultra-thin, high-strength Titanium, Poly Mesh, and Carbon Fiber into a fully integrated system - a combination never before used in driver face design.
This is paired with an ‘AI-Optimized Face Design’, where every part of the face is tuned to optimize speed, spin, and launch based on real impact patterns. Furthermore, the 360° carbon chassis is Callaway's lightest and strongest yet, freeing up weight for precise CG placement.
I have to say I was astounded when I first put the Quatum TD in behind the ball for testing; I thought I had entered a time warp! The look behind the ball is barely distinguishable from the Ai Smoke Triple Diamond of a couple of seasons ago. I mean, it is quite remarkable to be honest. We often see similar looks from manufacturers, but I don’t know if I’ve ever seen a model replicated so closely from this angle before.
Some may deem this as unimaginative and repetitive, while many others will be delighted at the return of a very popular playing profile from an extremely popular previous model. I would be interested in your opinions in the comments section below…
I would be lying if I said I was in love with the shaping; in truth, the last three low-spin drivers from Callaway have all been a touch on the triangular side in terms of playing profile to me.
For some reason, I personally lean towards rounder shapes in the driver, although that would be my only criticism of an otherwise excellent-looking head.
From the other angle, the sole aesthetic is as good as Callaway has produced in many years, in my opinion. The dark carbon weave, minimal branding, and very subtle red accent colors give it a mean, sophisticated, and high-tech appearance that looks fantastic in the bag.
My first hits with Quantum TD were extremely enjoyable. The feel is superbly powerful, providing a hefty crack at impact that really lets you know the ball has been hit. It’s not a muted thud; it’s an explosive sensation that matches the speed output on offer.
Performance-wise, the Quantum Triple Diamond is a beast. I gathered my data on my Foresight Sports GC3 launch monitor, and the first thing to say is that it is quick in terms of ball speed. Extremely quick.
In my testing, it was only second behind the TaylorMade Qi4D in that respect, and that was primarily because the aerodynamics of the TaylorMade driver simply allowed me to move it quicker through the air. Crucially, the Quantum Triple Diamond actually produced more bang for its buck for me in terms of a higher smash factor, suggesting the Tri-Force Face is more efficient at transferring energy.
The adjustability on offer is also a key feature for the better player. In the neutral setting, its ball flight offered a slight left-to-right bias for me, and shifting the 9-gram weight in the rear over to the toe side will genuinely help those who want to take the left side (for the right-handers) of the golf course completely out of play.
After a somewhat underwhelming year in 2025, Callaway is well and truly back, fighting at the very top end of the driver market with the Quantum Triple Diamond.
It combines raw speed with a tour-proven shape and meaningful adjustability. For the high-speed player looking for a penetrating flight and a powerful feel, this driver is a serious contender.
The Callaway Quantum Triple Diamond driver will be retailing at $699.99/£649.
