Golf Monthly's Callaway Big Bertha Fusion driver review, a new model said to help more golfers find the fairway off the tee

Product Overview

Overall rating:

Callaway Big Bertha Fusion driver


  • Feels incredibly solid at impact across the clubface and as a result, most will experience a tight dispersion and more fairways found.


  • Some golfers won’t generate the distance they’re looking for from their driver.

Key technology
Callaway has relaunched the Fusion franchise with an aerospace-grade titanium exoskeleton called an Exo-Cage. This has been paired with a crown and sole made from triaxial carbon, a material that is over 65 per cent less dense than titanium and more than 35 per cent thinner than Callaway’s previous composite material. This allowed Callaway engineers to relocate 35g inside the clubhead to optimise CG and increase the MOI. The triangular shaping of the head raises the MOI even more. To maximize speed, a Speed Step is positioned on the front of the crown to reduce aerodynamic drag.

GM Review

The profile of this driver harks back to the old FT-iZ driver, long from front to back and triangular in shape. You can see the triaxial carbon on the rear of the crown, almost creating a snakeskin effect, and combined with the red trim creates a very snazzy prospect in the bag.

Most club golfers would benefit from finding more fairways than a few extra yards and so the appeal of this model is significant. You may not achieve your fastest club speeds, especially if you opt for the shorter of the two shaft length options, but the stability of the clubhead at impact and the feeling of power as you pepper numerous points on the face is noticeable.

Knowing that the forgiveness is there helps you swing more freely and in sync, rather than trying to steer the ball down the fairway. Distance was still very impressive on well-struck drives. It feels very lightweight to swing, although you would think the head shape wouldn’t make it especially fast through the air. That said, this is helped by the inclusion of the Speed Step crown, which features on the Callaway XR16 driver and is said to reduce aerodynamic drag.

All in all, this driver is geared more towards the inconsistent ball striker that requires assistance in tightening his or her dispersion over longer carries, but that’s not to say it’s short by any means.


Ideal for golfers that can’t keep the ball in play regularly but who don’t want to lose yards by switching down to a hybrid or iron off the tee.
