Say hello to Callaway's two newest drivers

A driver face designed using artificial intelligence? Equipment editor James Savage gets his hands on the Epic Flash and Epic Flash Sub Zero

Our Callaway Epic Flash driver vs. Epic Flash Sub Zero driver test took place at Moor Allerton in Leeds.

We attended the brand’s launch event at their Carlsbad HQ in California to learn all about the new technology then put the drivers head-to-head in Moor Allerton’s fantastic indoor fitting studio.

Data was gathered using both Flightscope and SkyTrak launch monitors.

Callaway Epic Flash driver vs. Epic Flash Sub Zero: First impressions

Callaway Epic Flash

Epic is back! Well, it never really went away as it continued to run alongside the Rogue line which was launched last year.

But we’ve got some cool, new technology in the Epic Flash drivers which Callaway are very excited about.

If you were a fan of Epic first time around you should be excited too.

The looks at address are quite similar to the originals – they are a bit more compact than the super-forgiving Rogue models.

They have that same super-premium look but are interestingly both adjustable this time around.

We will still have the three Rogue (regular, draw, sub zero) drivers available in 2019 which Callaway say are a tad more stable and forgiving with their ‘weight-back’ design.

But the Epic Flash is promising even more ball speed than ever thanks to some all-new technology.

The key new tech in the Epic Flash is something called a Flash Face.

It has variable thickness and aims to offer more ball speeds right across it. It’s actually thinner in the middle which Callaway say means the odd drive you hit right out of the middle will go miles.

But it’s the way Callaway created this face which is most interesting.

They invested a lot of money in what they are calling a ‘super computer’ where they were able to input all of the relevant data about how to make a fast driver.

What materials, what size and shape, what tolerances it has to work to.

After around 15,000 iterations, this is the driver face the computer came up with.

They say it would take a normal computer or laptop around 34 years to run the same calculations.

The result is a face which claims to offer 1.5mph extra ball speed on their existing models.

The Epic Flash and Epic Sub Zero drivers also have the Jailbreak technology we saw two years ago in the original models.

This helps to add further ball speed by allowing the face to take more load at impact thanks to two titanium bars connecting the crown and the sole.

And the use of a super-light triaxial carbon crown means enough weight has been saved to add a moveable weight on the rear of the sole of both new drivers.

Callaway are certainly talking a good game with the Epic Flash but how do these new models perform?

That’s enough about the technology – how do they perform? Find out on the next page…
