What is the difference between auto start-stop and autohold?
2 Answers
The differences between auto start-stop and autohold are: 1. Different functions: Auto start-stop is a system that controls the engine's start and stop; autohold is an automatic parking function that automatically engages the handbrake. 2. Different purposes: Auto start-stop temporarily turns off the engine when the vehicle stops after braking; automatic parking actively holds the brake for the driver when the vehicle stops after braking. Auto start-stop automatically shuts off the engine during temporary stops while driving and automatically restarts the engine when it's time to move forward. Autohold refers to an automatic braking function. When activated, for example, when stopping at a traffic light, it eliminates the need to pull the handbrake.
After years of driving, I've noticed a significant difference between auto start-stop and autohold. Auto start-stop turns off the engine at red lights or in traffic to save fuel, and it restarts immediately when you press the accelerator, which is great for saving some money in the city but can be a bit annoying with the AC on in summer. Autohold, on the other hand, automatically locks the brakes after stopping, preventing the car from rolling, which is especially handy on slopes when waiting for traffic lights—no need to keep your foot on the brake pedal. The biggest difference is that start-stop saves fuel and energy, while autohold offers safety and convenience by preventing rollback. Using them together efficiently in daily driving can be very effective, like using start-stop plus autohold for a relaxed break at long red lights. However, you might want to manually turn off start-stop on bumpy roads to avoid frequent engine shut-offs. New car features are great, but they take some getting used to.
