The new seven-speed gearbox comprises of two dry clutches fitted with electric motor-driven actuators. According to KIA, it is 7 percent more efficient than the six-speed and improves acceleration times 5 percent. We may even see the new seven-speed gearbox in vehicles next year; however it has not been said when it will make its way to the U.S.
Combining battery, electric motor, and a small engine supercharger the new mild hybrid system increases power by 15 to 20 percent. The electric motor allows for a pure electric mode at low speed and cruising situations. Powered by a 48-volt lead-carbon battery, the mild hybrid battery is said to do better in cold weather as well as easier to recycle.
