In the UAE, the primary difference between 's Efficiency and Comfort modes lies in their adaptation to local driving conditions: Efficiency mode aggressively manages the air conditioning and powertrain to save fuel in high heat and traffic, while Comfort mode prioritizes cabin cooling and smoothness over fuel economy. Based on data from RTA Dubai and the UAE Ministry of Energy and Infrastructure, fuel consumption can vary significantly. For a typical GCC-spec Audi Q8 using Super 98, the annual cost difference can be substantial.
| Mode | Estimated Fuel Economy (Mixed UAE Cycle) | Key System Behavior in UAE Context |
|---|---|---|
| Efficiency | ~7.2 km/l | AC compressor runs at lower priority; earlier upshifts; coasting function active. |
| Comfort | ~6.5 km/l | AC prioritizes rapid cooling; softer throttle mapping; suspension at its softest setting. |

I use a 2022 A6 for my daily commute from Sharjah to Dubai. In the brutal summer traffic on Sheikh Zayed Road, I keep it in Comfort mode. The throttle is less jumpy in stop-and-go traffic, and the AC cools the cabin much faster when I get in after work—that's worth the extra few fils per kilometer in fuel for me. I only switch to Efficiency for the occasional weekend trip to Abu Dhabi when the traffic is clear.

As a manager at a used car showroom in Dubai, I advise clients to test both modes. Cars that have spent most of their life in Comfort mode might show slightly more wear on brakes and suspension bushings from the softer, more rolling stops. The fuel economy readout in the trip computer often tells the story. A car that shows a long-term average of below 7.0 km/l for a 2.0L engine has likely been driven mostly in Comfort or Dynamic mode in city traffic, which is normal here. It doesn't hurt the car, but it's a data point on previous ownership style.

For desert driving or even on dusty roads near Al Qudra, avoid Efficiency mode. It reduces throttle response and might cut power when you need it most for maintaining momentum in soft sand. Keep it in Comfort or, better yet, switch to All-Road or Off-road mode if your has it. The priority in the desert is controlled power, not saving fuel.
