Mazda announced the CX-60, a mid-size SUV that embodies the joy of driving, which is the real pleasure of the Mazda brand, while combining the high safety performance and environmental performance required of modern cars. This product is the top batter in the Large product lineup, and it plays an important role in taking Mazda's brand value management to the next level. As Mazda's unique approach, we have developed a new type of vertical automatic transmission (AT) in order to pursue a human-centered development philosophy and realize the joy of driving with "Jinba Ittai". In developing the new AT, we focused on dramatic improvements in transmission functions such as intermittent, synchronous, and transmission efficiency, and instead of using a fluid torque converter, we adopted a mechanical clutch mechanism like a manual transmission to create a direct start. We aimed for high response and smooth shifting performance, and high efficiency by reducing resistance. At the same time, by optimally incorporating gear ratio setting and shift control, driving with a sense of rhythm that matches human senses is realized, and by designing a compact design, an ideal driving posture is realized, and with the car. I made it possible to feel the ultimate sense of unity. In order to satisfy the environmental performance that is becoming more severe year by year, we have adopted a structure that can incorporate a 48V mild hybrid and plug-in hybrid electric drive system.
