Titleist Introduces New TSi4 Driver
An Ultra-Low Spin Design with Advanced Speed Complements Popular TSi2 and TSi3
CARLSBAD, Calif. (February 17, 2021) – The introduction of the new Titleist TSi4 driver provides golfers seeking ultra-low spin performance with the advanced speed and distance gains that have made Titleist TSi2 and TSi3 the most played driver models this season on the PGA Tour.
The new TSi4, the driver choice of Adam Scott, Russell Henley and Richy Werenski, among others on the PGA Tour, is engineered to be a high-speed, ultra-low spin design – challenging the notion that a driver designed for extreme spin reduction can’t produce that level of ball speed.
“The TSi4 fulfills the ultra-low spin product within our TSi lineup,” said Stephanie Luttrell, Director of Titleist Metalwood Development. “For those players that need aggressive spin reduction to improve their distance, we now have that product in the TSi lineup.”
The Center of Gravity (CG) is the lowest in the TSi family of drivers and it is also the most forward. That allows the driver to deliver less dynamic loft and less spin at impact, providing that low spin promise. A higher Moment of Inertia (MOI) in the TSi4 also contributes to a higher launch, overall trajectory, and produces more distance for that target player. At 430cc, with a very classic, small pear-shaped profile and improved sound and feel, the TSi4 is also the most workable of all TSi drivers.
“In general, high spin comes from players that either come over the top, have a steep attack angle, or are adding significant loft at impact,” said Luttrell. “So, the TSi4 is not strictly reserved towards high speed players, but absolutely dedicated towards all golfers who require spin reduction in order to improve their distance by producing a longer, more piercing ball flight.”
ATI 425 AEROSPACE TITANIUM FACE
Faster in the air and faster at impact, all Titleist TSi 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 – that combine to produce the longest, straightest, best-looking, and best-sounding Titleist drivers ever.
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.
ATI 425 Aerospace Titanium is 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. 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 company in golf that uses this material.
PLAYER-TUNED AERODYNAMICS & SOUND
The improved shaping of the TSi4 allows the club head to move faster through the air and deliver more power at impact. The TSi4 has been aerodynamically engineered to reduce drag up to 6 percent (versus prior generation TS4 model), increasing club head speed for greater ball speed and distance.
While golfers often equate “high MOI” with heel to toe forgiveness, Titleist R&D employs a more holistic approach to MOI design. TSi optimizes sole to crown performance by producing higher inertia values versus the prior generation TS models and delivers 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.
The TSi4 features Titleist’s patented SureFit hosel with 16 independent loft/lie settings, plus headweight adjustability (in two-gram increments, ranging from -4g to 4g) to create a more consistent and optimized ball flight through precision fitting.
CT TESTED AND MAXIMIZED
Every TSi4 driver is precision manufactured to the tightest tolerances and measured multiple times to ensure performance is at the maximum allowable limit.
ULTRA-THIN TITANIUM CROW
The thinnest cast titanium crown in the game allows weight to be redistributed low and forward for reduced spin.
The aerodynamic design of TSi4 – featuring a 430cc classic, pear shape – reduces drag, allowing golfers to swing faster for increased club head speed and more distance.
