Titleist TSi Drivers: Aerodynamic Aerospace Advantage

The new Titleist TSi2 and TSi3 drivers push the boundaries of speed through advanced engineering and material breakthroughs, including a new ATI 425 Aerospace Titanium face construction never before used in golf.

Hailed as the longest, straightest, best-looking and best-sounding Titleist drivers ever, the new models transcend the advancements of the original Titleist Speed Project. TSi2 and TSi3 hit retail shelves on November 12 with fittings already available at locations nationwide.

From the top of the swing, TSi’s aerodynamics propel the clubhead faster toward the ball. At impact, the powerful ATI 425 face launches the ball with added speed. High inertia properties produce an extremely stable clubhead for more consistent speed and spin across the face.

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.

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 conventional titanium alloys used in golf.

The exceptional ductility of ATI 425 (30% higher than 6-4 Titanium) allowed engineers to produce Titleist’s fastest driver face, while maintaining the durability required for consistent performance. The face also features a new high-contrast graphic design that accentuates the center for easy alignment.

Made by a single foundry in Pittsburgh, ATI 425 was initially developed for ballistic armor 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 golf company that uses this material.

Both TSi2 and TSi3 have been aerodynamically engineered to reduce drag up to 15% (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.

This 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% 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.

Every TSi driver is precision manufactured to the tightest tolerances and measured multiple times to ensure performance is at the maximum allowable limit.

The TSi3 features a new SureFit CG track technology with 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 and T2 (most toe biased) – allowing players 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 2g increments, ranging from -4g to 4g) for precision fitting.

TSi has become the most played driver on both the PGA and European Tours since being introduced to players the second week of 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 US Open, TSi was the most played driver model at Winged Foot.

More than 150 players across the world’s professional tours have played new TSi2 or TSi3 models in competition over the past five weeks. There are currently 20 players in the Official World Golf Rankings Top 100 carrying a new TSi model, including four in the Top 20 using TSi3 – Justin Thomas, Adam Scott and two uncontracted players.

“TSi just looks fast and it sounds like a missile coming off the face,” said Thomas. “Those weeks where I’m not hitting it consistently in the middle of the face, I feel like this [TSi driver] is going to give me the opportunity 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.”

TaeHoon Kim was the first Titleist player to win with a TSi wth his victory in the Korean PGA Tour’s Genesis Championship, using a TSi2 driver (9.0) and a TSi2 (15.0) fairway.

Titleist has been the most played driver on the PGA Tour for two seasons running.

Golfers can experience the new TSi metals by attending a Titleist fitting day or trial event in Singapore, Malaysia and Thailand. To find an event or book a free TSi metals fitting, click here.
