Why Are Top Sports Cars Mostly Manual Transmission?
1 Answers
Reasons why automatic transmissions are unsuitable for racing: lower gear-shifting efficiency, greater power loss, and inability to withstand high torque. Manual transmissions are lighter than automatic ones, with manual transmission cars generally weighing about 50kg less than their automatic counterparts. Physical mass affects acceleration, so manual transmission cars are also slightly faster by about 1.5 seconds. Below is an introduction to manual transmissions in sports cars: 1. Supercars: Almost all are semi-automatic, meaning they can be manually controlled or automatically adjusted by the car. Sports cars emphasize control and speed, which automatic transmissions generally cannot perfectly achieve. To obtain a better driving experience, manual shifting is necessary. 2. Manual Transmission: Manual transmission cars have only one gearbox and one clutch, but sports cars have dual clutches, with one responsible for even-numbered gears and the other for odd-numbered gears. This ensures uninterrupted power transmission, allowing for automatic shifting as well as a manual mode, similar to semi-automatic transmissions. Sports cars typically use paddle shifters for gear changes, which are standard configurations. Supercars, with their powerful gearboxes and clutches, can complete a gear shift in as little as 0.3 seconds.
