Manual transmission cars do not need ESP. ESP stands for Electronic Stability Program, which reduces the power transmitted by the transmission to bring an out-of-control car back on track. The working principle of ESP is: it judges the driving state based on sensor signals and uses a control unit for precise calculations. When situations like spinning, understeering, or oversteering occur, it individually controls each wheel to improve vehicle stability. The functions of ESP are: 1. Precisely controlling the braking process of one or more wheels and distributing the braking force applied to each wheel; 2. The EPS system automatically adjusts the engine's output torque to control the vehicle's speed; 3. Forcing the car to generate a rotational torque around its center of mass, replacing the driver in adjusting the car's direction.

As a long-time car owner, I believe manual transmission vehicles also need ESP. Having driven manual for over a decade, ESP can be a lifesaver in rain or snow. Once when turning on icy roads, the rear wheels suddenly lost traction, and ESP immediately intervened to help stabilize the direction. This system doesn't discriminate between transmission types—it automatically monitors each wheel's speed, reduces engine output when tires lose grip, and individually brakes the slipping wheels. Manual cars are more prone to fishtailing during sharp turns or on slippery surfaces, where ESP helps prevent skidding accidents. Europe has mandated ESP for all new cars since 2014, regardless of being automatic or manual. Spending a few thousand extra for ESP when choosing a car is far more cost-effective than post-accident repairs, and crucially, it can prevent rollover risks in critical moments.

I recommend all manual transmission car owners to install an ESP system. Last month, my cousin's accident on a mountain road was a lesson: his front wheels skidded while driving a manual transmission down a steep slope, and the car almost went off the road. ESP can analyze the steering wheel angle and the vehicle's lateral movement speed in real-time, actively applying brakes before losing control. Many people think that manual transmissions have good handling and don't need it, but shifting mistakes or excessive throttle can more easily cause skidding. Nowadays, domestic manual transmission cars in the 100,000 yuan price range basically come with ESP as standard. This system will alert you to the vehicle's status through the dashboard indicator lights, which is especially important for novice drivers. You might not need it often, but in emergency avoidance situations, you'll know it's worth it.

Manual transmission cars indeed benefit from having ESP. I've analyzed track day vehicle data and found that manual cars equipped with ESP demonstrate higher cornering limits. This system incorporates steering angle sensors and yaw rate sensors, capable of detecting loss of control risks within 0.05 seconds. The power interruption during manual gear shifts can easily cause sudden changes in traction, which ESP effectively compensates for. Many manufacturers, like Volkswagen with their manual Golf models, now make ESP standard equipment. It proves particularly useful on frosty winter roads by preventing understeer or oversteer. While it may slightly increase purchase costs, the safety improvement is significant.
