Callaway say this allows them to improve the forgiveness and promote high launch and lower spin off the tee.

Callaway say the XR Speed has the lightest and most flexible face they’ve ever produced which should produce fast speed over a larger area.
Callaway XR Speed driver vs XR16: The results

I tested the Callaway XR Speed driver with the new Project X Hzrdus Blue shaft which is 65g and has a flex of 6.0. It’s supposed to be a ‘mid-spin’ shaft.
I used the exact same shaft in the XR16 driver.
When I started hitting the XR16 I remembered why I liked it so much first time around. It’s the sound and feel off the face – it just feels like the ball is coming off so quick.
It’s easy to use and is forgiving on the mis-hits. But it was going a bit too high, and at times, spinning too much.
I actually found myself adjusting my technique to try and keep the ball down.
When I started hitting the XR Speed, I also really impressed with the sound and feel. But it’s more solid and meaty than the XR16. It’s not as high pitched.
The XR Speed had a bit less spin than the XR16 for me which is one of the reasons why we had a little bit more carry.
The best carry of 247 yards with the XR Speed puts it right up there with the best drivers I have tested in 2018.
Callaway XR Speed driver review: NCG verdict
If you currently use the XR16 is there enough improvement in the XR Speed to warrant the upgrade?
For me, there were definite improvements but these could have been down to suitability for my swing rather than genuine performance gains.
Unless my XR16 was completely battered, I wouldn’t be rushing out to buy the XR Speed.
However if my driver was four or five years old and I was looking for an upgrade and looking to spend around £300 – then the XR Speed would be right at the top of my shopping list.
If there’s a better driver out there for the same price at the XR Speed then I’m yet to test it.
