Callaway Quantum Triple Diamond Driver Review: Big distance, bigger price tag

Callaway Golf sold more golf clubs than any other brand in America in 2025, and drivers like the Elyte range were a key reason why. It was exceptionally fast, very good looking, and came in a huge array of different types, from the ultra-long Triple Diamond models to the uber-forgiving Elyte X.

The low-spin Elyte Triple Diamond leaves particularly large shoes to fill. Named by many testers as one of the longest, fastest drivers of 2025, it was also among the most prolific drivers seen at a tour level, representing the very pinnacle of what the brand can achieve in terms of generating pure speed and control for better players.

That, however hasn't put Callaway off from making some seriously bold claims with its new Quantum Triple Diamond, promising, as the name suggests, a quantum leap forward in speed and distance. With that, however, comes an even bigger price tag (a jump of £50 on last year's model, to be exact).

So does the Quantum Max- produce the performance to rival the best low-spin drivers of 2026? And perhaps most importantly, is it a big enough upgrade over its excellent predecessor to warrant the higher price point? We took it out on course at Quinta do Lago to find out.

Check out our video review below and scroll on to read our detailed thoughts. Let us know what you think of the new  Callaway Quantum Max driver in the comments below.

Looks & features

While they share similar names, the difference between the Triple Diamond models and their siblings in the Max and Max-D models is far more distinct than that we've seen in previous Callaway driver line-ups.

Straight away you can tell one from the other, and we think the Triple Diamond presents a far more alluring visual package. The 360-degree carbon crown is rendered in clean carbon fibre that wraps around both the crown and the sole, while the Triple Diamond also forgoes the Max's light grey accents for a more streamlined, premium look. It's a lovely thing to behold, particularly with its slimmer 450cc tour-shaped profile, and helps explain why it'll set you back a full £50 more than its more affordable stablemate.

The two Quantum Triple Diamond drivers do, however, share a lot of the same new technologies Callaway is introducing across the Quantum range for 2026. The headliner among these is the brand's new Tri-Force face, which layers titanium and Poly Mesh over an internal carbon fibre insert – a combination of materials Callaway says has never been used in a driver before.

This face has been further engineered with the use of Ai to produce more flex and speed at optimum points across the face, delivering blistering ball speeds and more forgiveness and consistency on off-centre strikes. In the case of the Triple Diamond, Callaway have also used the lighter properties of the carbon crown to push more weight out towards the perimeter of the club, theoretically improving forgiveness.

Performance

Callaway made some pretty big claims in the lead-up to unveiling this driver, chief among them being that the Quantum name represents the 'quantum leap' its new face would provide in terms of ball speed and distance. And make no mistake about it: this is a fast driver – possibly the fastest we've tested in 2026 – but it's also one that takes quite a specific kind of player to get the most out of it.

The Quantum Triple Diamond delivered consistently fast speeds in our testing, impressive distances and a low, penetrating ball flight, with some of the best carry and distance numbers we've seen in any of the drivers we've tested so far this year. 

The new Tri-Force face also provides a much meatier, powerful sensation compared to some of Callaway's previous models, which you'll no-doubt like if you prefer a firmer-feeling driver.

However a small issue remains in the fact that last year's Elyte was, according to a lot of testers, among the fastest drivers on the market. You'll likely only see very marginal gains between the two rather than the huge leap promised in the name, but in the hands of an able higher swing-speed player, the Triple Diamond still produced near-unprecedented ball speeds, making this a surefire contender for the fastest driver on the market right now.

The main issue, as is perhaps to be expected with a lower-spin tour-shaped driver, is that of forgiveness. The Triple Diamond is forgiving by the standard of other smaller low-spin drivers, but will certainly punish mishits with a pretty big drop off in speed and distance if you're not on your game.

It's worth mentioning, however, that Callaway have bridged the gap between the Triple Diamond and Max models with the Triple Diamond Max for the first time as a mainline entry in its line-up, which has a more forgiving 460cc shape and the same low-spin properties. We're yet to test it out properly, but recommend you do so if you want that little extra forgiveness while achieving that lower launch.

Callaway's Quantum Triple Diamond drivers challenge the very upper echelons of distance and speed in the driver category for 2026, and we wouldn't be surprised if external testing revealed the Quantum range, whether in its Max or Triple Diamond form, sat at the very upper end of speed and distance tests once again in 2026.

Is it the 'quantum' leap Callaway are promising? Not quite, but such a leap is always going to be hard to attain with every manufacturer hitting USGA limits already – especially in the case of Callaway which has the unenviable task of one-upping itself over and over again.

All the same, Callaway have a very fast, very high-performing driver for 2026 in the Quantum Triple, with a good degree of adjustability and potentially the fastest ball speeds of any driver on the market – if you have the game to unlock them.

The price of the Quantum Triple Diamond is an issue. It clocks in at a whopping £649 (£100 more than the TaylorMade Qi4D and a full £180 more than a Cobra's new OPTM LS), making it the most expensive driver of any offered by the big five OEMS (aside from PING's new G440 K). We expect that might cost it a few sales in the showroom when push comes to shove. Even so, if can afford the extra outlay, this is still a driver well worth testing.
