Does keeping autohold on consume more fuel?

Keeping autohold on does consume more fuel. Here is a related introduction to the autohold automatic parking function: 1. Autohold, the English name for automatic parking, refers to an automatic braking function. After activating this function, for example, when stopping at a traffic light, it is equivalent to not needing to pull the handbrake, simplifying operations by avoiding the use of manual or electronic handbrakes. Automatic transmission models also do not need to frequently switch between D to N or D to P. 2. Automatic parking is an extension of the ESP function and is controlled by ESP components. When the vehicle is temporarily parked and needs to restart after a short period, the parking in this situation is completed by the ESP-controlled braking. The computer uses a series of sensors to measure the vehicle's level and wheel torque, determines the vehicle's tendency to move, and applies an appropriate braking force to the wheels to keep the vehicle stationary.
I've been using autohold for my daily commute and have gotten so used to it that I don't feel it consumes more fuel. During red lights or traffic jams, it automatically holds the brakes for me, saving me from the fatigue of constantly pressing the brake pedal. Autohold only activates when the car comes to a complete stop, and the engine maintains its normal idle speed—it's not much different from regular idling. It doesn't consume fuel as aggressively as running the AC or accelerating hard. Over the years I've driven this car, my fuel consumption has remained stable. Autohold places minimal load on the engine; fuel efficiency mainly depends on gentle acceleration when starting—just ease onto the throttle to save fuel. Remember, modern car systems like this are designed to be energy-efficient. Using autohold long-term won't increase fuel costs; in fact, it makes traffic jams more comfortable. For maintenance, just check the brake pads regularly—it's hassle-free overall, so don't worry about it holding you back.
I think having autohold on basically doesn't affect fuel consumption, it really depends on how you use it. It takes over the braking system when the car is stationary without adding extra mechanical load—the engine is still running as usual, and idle fuel consumption remains the same. I've checked my car's data, and the dashboard fuel consumption shows no noticeable change with autohold activated, unless you frequently start and stop the car, causing the engine to restart repeatedly—but that's more of a driving habit issue. The system itself is efficient, and keeping it on actually enhances safety, eliminating the need to constantly engage the brake at red lights, which is especially helpful for beginners. I recommend using autohold wisely in combination with cruise control, switching between them on highways to maintain steady overall fuel consumption.
I often keep the autohold function on during my commute, and I haven't noticed any significant increase in fuel consumption. Mainly because it activates when the car is stationary, and the engine is already idling without any additional load, so it naturally doesn't affect fuel consumption. Fuel consumption depends more on your driving style, such as rapid acceleration or driving at high speeds with excess weight, which really burns fuel. The autohold function only serves as an assist and even saves wear on the brake pads. There's no problem with long-term use, so feel free to keep it on.
