Titleist introduction of the new TSi2 and TSi3 drivers and is placing emphasis on the fact they are not just an update of the previous TS models but make use of a new design with a very interesting titanium alloy for the face. Both TSi models (Titleist Speed impact) are meant to put the company squarely in the premium end of the very competitive performance driver category.

Interestingly with the pandemic-induced increased number of rounds and subsequent increase in the equipment sales the company is following some of the other club companies by raising the prices. The two new models are $50 more than the ones in the Titleist lineup they replace that were introduced in 2018.

The face of both the TSi2 and TSi3 is made from ATI 425, a titanium alloy not used in golf club manufacture until now that was originally developed for aerospace and applications such as ballistic armor and NASA’s Phoenix Mars Lander.

“ATI 425 is an amazing alloy that leads to a lot of performance benefits,” said Dan Stone, Senior Vice President, Titleist Golf Club R&D. “It’s incredibly strong and maintains elongation under high stress. It let us optimize 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.”

Head shapes have also been modified and according to Titleist data reduce drag up to 15 percent versus prior generation TS models on the theory that less air resistance will result in higher downswing speed and therefore distance.

“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. “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 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.”
