What does 'efficiency' mean when it appears on an Audi?

[DeAna]

In cars, 'efficiency' refers to the high-efficiency driving mode switching function. This function is designed to cater to an eco-friendly and energy-saving driving mode. When activated, the transmission shifting, engine response, air conditioning, etc., all operate according to the preset energy-saving mode, which can reduce fuel consumption and carbon emissions. Other driving modes in cars include: 1. Economy Mode: Through advanced shifting programs and optimized operation, it effectively reduces the engine's fuel consumption and emissions, making it a highly energy-efficient and eco-friendly driving mode; 2. Comfort Mode: The transmission shifts gears at lower engine speeds, saving both effort and fuel; 3. Sport Mode: Suitable for enjoying spirited driving on winding roads, the engine shifts gears at higher speeds, with very responsive throttle, quick acceleration, and powerful performance.

When I see the word 'efficiency' on an Audi car, it usually refers to the activation of the high-efficiency energy-saving mode in the vehicle's driving mode selection. This mode proactively adjusts the working logic of the engine and transmission, such as reducing throttle sensitivity, making gear shifts occur earlier, and even optimizing the energy consumption of the air conditioning system. Simply put, it allows the car to travel farther with less fuel. I particularly like using this mode for urban commuting as it significantly saves on fuel costs. However, on highways, you may notice that the power output isn't as exhilarating as in dynamic mode. When this indicator appears on the dashboard, it typically means the vehicle is currently operating in its most economical state.

When "efficiency" appears on the Audi dashboard, it indicates the vehicle is operating in a fuel economy priority mode. I specifically tested this feature while driving an Audi A6: it achieves fuel savings by limiting acceleration response, reducing air conditioning power, and enhancing energy recovery. The most noticeable change is that the throttle feels less aggressive when pressed, and the RPM is maintained in a lower range. Once when driving from Beijing to Tianjin using this mode throughout the journey, I surprisingly used 1.5 liters less fuel than usual. However, a reminder: it's best to switch modes when rapid acceleration is needed for overtaking, otherwise, the power might be insufficient.

This is the efficiency mode indicator in Audi's drive select system. When activated, the vehicle automatically enters a fuel-saving state: the transmission upshifts more aggressively, the start-stop system becomes more active, and throttle response becomes softer. I've noticed that in this mode, the air conditioning automatically increases the set temperature to reduce cooling load, and even the power steering becomes lighter to decrease energy consumption. If you've just refueled and are going on a long trip, it's recommended to enable this mode to control fuel consumption.
