Gram Strategy to Achieve Optimal Weight Reduction

Mazda currently puts emphasis on the optimal weight reduction of the all-new Mazda MX-5 model in its latest TV commercial. As the most popular small-size convertible automobile model , Mazda should, of course, do whatever it takes to achieve the best performance of its new MX-5 model. The MX-5 released in the European market weighs 998kg in total per vehicle, so it has never been easy to achieve a 50:50 weight distribution when a driver is also sitting in the car and the goal of super lightweight.

Engineers of Mazda are now using “Gram Strategy,” which means the addition of any extra gram of weight has to be avoided. The simplest example should be screws. Torx screws (which demonstrate the same function with less head areas compared to other screws installed on the right side of the car) are installed on the left side of the MX-5. As each of these Torx screws is 8g less than other generally used one, a car in need of thousands of screws can thus achieve more weight reduction. That is why MX-5 can weigh the same as its first-generation model but with more powerful performance.
