Titleist has expanded their driver family once again with the newest TSi collection. They’re calling the new additions the “longest, straightest, best-looking, and best-sounding Titleist drivers ever.”

From the top of the swing, TSi’s player-tuned aerodynamics are designed to propel the clubhead faster towards the golf ball. At impact, the powerful ATI 425 face launches the ball with added speed. High inertia properties produce an extremely stable clubhead, intended to provide 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 maximize distance.
• TSi3 is for players capable of creating more consistent contact or requiring more precise control over CG placement, featuring a new SureFitCG Track Design For advanced speed-tuned performance.

“TSi is simply better when it comes to all four fundamentals of driver design – distance, accuracy, looks and sound,” said Josh Talge, Vice President, Titleist Golf Club Marketing. “ATI 425 is an incredible breakthrough for driver performance, but it's just one piece of the puzzle. Every aspect of TSi has been optimized 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.”

ATI 425 AEROSPACE TITANIUM FACE
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 what Titleist calls their fastest driver face, while maintaining the durability properties required for consistent maximum performance.

Made by a single foundry in Pittsburgh, ATI 425 was initially developed for ballistic armor and has since been used in many aerospace and industrial applications, including 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 center for easy alignment at address.

PLAYER-TUNED AERODYNAMICS & SOUND
The improved shaping of TSi allows the clubhead 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 clubhead speed for greater ball speed and distance. The new head shapes feature a tour-requested softer toe profile that looks square at address.

MULTI-DIMENSIONAL STABILITY
While golfers often equate “high MOI” with heel toe forgiveness, Titleist R&D employs a more holistic approach to MOI design. TSi also optimizes 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-optimized 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.
