This is an app competeing for accelarateing from 0 for 100kph. This app is based on the strong and original physics engine calculating relation of an engine rpm, a torque and an energy, a car speed and an energy, and a clutch temperature that lost as a thermal energy. That makes you enjoy launching the car! It’s little bit difficult and fun! In the battle mode, you can compete against the computer. If you win, you can tune the car up! Let’s get the champion of the clutch meet! The operation is simple. Your left thumb operates a clutch, and another thumb operates a throttle. When signal is black out, bite the clutch partially, and open the throttle. Important thing is balance on the throttle and the clutch.
