How fast can you go in second gear?

Answer 1

The maximum speed a car can go in 2nd gear is primarily dependent on the gears in the car's transmission. It can also be affected by the overall diameter of tires on the car as well as the maximum engine speed of the car's engine. To determine the maximum speed for a specific car you would need to have knowledge of that specific car's maximum engine speed, the transmission's 2nd gear ratio and final drive ratio, and the overall diameter of the tires on the car. Adding a larger wheel/tire combo will increase the top speed in each gear. Increasing the car's maximum engine speed, or redline as it's commonly referred to, via an aftermarket chip or computer reflash, will allow a higher maximum speed in each gear as well. Without modification, most factory cars will have a maximum 2nd gear top speed between 60mph and 70mph. This figure typically goes up for larger engined vehicles and down for smaller engined vehicles. The more gears a car has will generally mean a lower maximum speed in the first few gears. A sportbike can achieve a speed over 100mph in it's 2nd gear
