Titleist Unveils New TSi Drivers

By: Golfshake Editor | Thu 15 Oct 2020

Deploying advanced engineering and materials, including the ATI 425 Aerospace Titanium face construction that is a first for golf, Titleist has unveiled its new TSi Drivers, which have been created to deliver the longest, straightest, most attractive and best-sounding clubs the brand has released to date.

Available in Titleist authorised retailers from November 12th, with fittings beginning October 22nd at locations nationwide, the new TSi2 and TSi3 models transcend the advancements of the original Titleist Speed Project, accelerating the performance that has made Titleist the most played driver on the PGA Tour for two seasons running.

From the top of the swing, TSi’s player-tuned aerodynamics propel the clubhead faster toward the golf ball. At impact, the extremely powerful ATI 425 face launches the ball with added speed. High inertia properties produce an extremely stable clubhead, providing players with more consistent speed and spin across the face for longer, straighter drives:

TSi2 is designed to deliver incredible speed and accuracy across the entire surface of the face, with a deeper, lower CG to maximise distance.

TSi3 is for players capable of creating more consistent contact or requiring more precise control over CG placement, featuring a new SureFit CG Track Design for advanced speed-tuned performance.

Titleist's Josh Talge said: “TSi is simply better when it comes to all four fundamentals of driver design – distance, accuracy, looks and sound. We continue to make every investment necessary to help players achieve the speed and distance gains they are asking for, without having to make any sacrifices when it comes to performance. ATI 425 is an incredible breakthrough for driver performance, but it’s just one piece of the puzzle. Every aspect of TSi has been optimised to benefit the total package, and it’s the integration of all those parts that drives greater ball speed and an experience at impact that tour players can’t stop talking about."

The first week that TSi drivers were made available on the PGA and European Tours in early September, a total of 57 players immediately made the switch, with more players choosing TSi drivers than any other model across the two events. The following week at the U.S. Open, TSi was the most played driver model at Winged Foot Golf Club.

Justin Thomas said: “TSi just looks fast and it sounds like a missile coming off the face, when I first tested it I hit one drive off the toe and it carried almost 20 yards further than I would have thought. That’s what we want is the bad ones to perform better. Those weeks where I’m not hitting it consistently in the middle of the face, I feel like this [TSi driver] is going to have the opportunity for me to narrow my window and dispersion. The fact that it is faster without giving anything up – I can’t believe how much it’s improved when it already seemed to be the best that it can get.”

ATI 425 Aerospace Titanium Face

Accurately tuned for speed at every point of contact, TSi driver faces are constructed from ATI 425 Aerospace Titanium, a unique material that delivers superior strength, elasticity and durability versus the conventional titanium alloys used in golf. The exceptional ductility of ATI 425 (30 percent higher than 6-4 Titanium) allowed engineers to produce Titleist’s fastest driver face, while maintaining the durability properties required for consistent maximum performance.

Titleist's Dan Stone said: “ATI 425 is an amazing alloy that leads to a lot of performance benefits, It’s incredibly strong and maintains elongation under high stress. It let us optimise the thickness of the entire face to a degree that was never possible before and generate our highest ball speeds ever at points all over the face – not just heel and toe but also high and low. This is not an easy material to obtain, but the benefits to the golfer are beyond anything we’ve ever seen.”

Made by a single foundry in Pittsburgh, ATI 425 was initially developed for ballistic armour applications and has since been used in many aerospace and commercial aircraft solutions, including jet engines and NASA’s Phoenix Mars Lander. Titleist is the only company in golf that uses this material.

The TSi face also features a new high-contrast graphic design that accentuates face centre for easy alignment at address.

Aerodynamics & Sound

The improved shaping of TSi allows the club head to move faster through the air and deliver a more powerful impact. Both TSi2 and TSi3 have been aerodynamically engineered to reduce drag up to 15 percent (versus prior generation TS models), increasing club head speed for greater ball speed and distance. The new head shapes feature a tour-requested softer toe profile that looks square at address.

TSi feels fast in a golfer’s hands and is complemented by meticulous sound engineering that manages vibrations within the club head to deliver a Tour-quality sound.


While golfers often equate “high MOI” with heel to toe forgiveness, Titleist R&D employs a more holistic approach to MOI design. TSi also optimises sole to crown performance, producing up to 13 percent higher inertia values (versus prior generation TS models) that deliver more speed and a tighter launch and spin range up and down the face.

TSi’s speed-optimised MOI works in concert with a low and deep CG position to drive faster ball speed with a high launch, low spin trajectory and exceptional stability for greater distance consistency.


The new TSi3 model features a new SureFit CG track technology that offers five unique positions to adjust club head CG and fine-tune ball flight. The track offers more precise incremental adjustments – H2 (most heel biased), H1, Neutral, T1, T2 (most toe biased) – allowing a player to dial-in their launch conditions.

Both TSi2 and TSi3 feature Titleist’s patented SureFit hosel with 16 independent loft and lie settings, plus headweight adjustability (in two-gram increments, ranging from -4g to 4g) to create a more consistent and optimised ball flight through precision fitting.
