The new XCG-4 series offers legendary performance. Available in a 276-gram super-ultra-light and 310-gram ultra-light editions, these turbo-charged drivers are guaranteed to thrill and inspire like no other club has before.With the development of the XCG-4 driver, Exotics engineers have carried out extensive work to create one of the lightest, most aerodynamic drivers in golf. The XCG-4?s new sleek design and heavily-radiused sole allow for a more streamlined, fluid head shape that minimizes drag as the driver cuts through the air. Powered by the game?s most advanced lightweight shafts, the XCG-4 is a true distance weapon of the tee.The heart of the XCG-4 is an advanced head design that features a titanium face and sole, an amorphous carbon crown, two amorphous carbon sole inserts, and two tungsten sole weights. The ultra-light weight carbon frees up 27 grams of weight that is strategically positioned in the lower rear of the clubhead to improve MOI by more than 15% over previous versions. The result is longer tee shots that hold the target line even on off-center contact.To maximize spring-like effect, Tour Edge engineers created the Boomerang face. This supercharged design offers multiple levels of variable face thickness that maximize the rebound effect from more points on the face. By thinning and thickening the face, the v-shaped boomerangs allow for the maximum elongation of the titanium for enhanced feel and hotter rebound. The new design increases the XCG-4?s rebound to 243ct ? up from 232ct in the XCG-3. With just one swing of the XCG-4, you?ll feel and see the difference.The ultra-light version of the XCG-4 delivers the lightest driver on the market with a total club weight of only 276 grams. It features a 45-gram ultra-light Graphite Design Tour AD 46? shaft and a 26-gram Winn Lite grip. The standard version weighs 310 grams and comes with a Fujikura Motore 55-gram, 45.5? long shaft and a Golf Pride New Decade grip. Give both models a test drive and experience for yourself the heart and soul of Exotics.
