The official combined fuel consumption of the RDX two-wheel-drive model is 8.2L/100km, and that of the four-wheel-drive model is 9L/100km. The actual fuel consumption is related to the vehicle condition, road conditions, and personal driving habits. Vehicle fuel consumption is influenced by the following factors: 1. Advanced automotive technology is crucial for fuel consumption. The vehicle's own weight, body design, and engine thermal efficiency are three key automotive technologies related to fuel consumption. 2. Good vehicle condition is the foundation of fuel efficiency. In addition to keeping the car clean, proper maintenance is essential, such as lubricating wheel bearings regularly, replacing the air filter element periodically, and checking the brake system promptly. 3. Incorrect driving habits can significantly increase fuel consumption. Smooth acceleration, steady driving, and timely gear shifting are the most basic fuel-saving techniques. Start smoothly without stomping on the accelerator for a sudden burst of speed; instead, press the accelerator gradually to allow the car to start and move at a steady speed. When waiting at a red light, avoid competing with neighboring vehicles for a quick start. On the road, try to maintain a steady speed. Except in emergencies, avoid sudden acceleration and braking, refrain from weaving through traffic to overtake, minimize accelerating in low gears, and avoid revving the engine before shifting gears. Additionally, coordinating clutch engagement and accelerator pedal use accurately is important, as doing either too early or too late can increase fuel consumption.

I've been driving an RDX for two years, and the fuel consumption really depends on the usage scenario. For daily city commuting with frequent traffic lights, the fuel consumption is around 11-13 liters per 100 km. It's more economical on highway cruising, roughly 7-8 liters per 100 km. If you floor it in sport mode, the consumption can instantly spike to over 15 liters. Mine is the AWD version, which burns about 1 liter more per 100 km compared to my friend's FWD model. The fuel tank capacity is 60 liters, and a full tank can get you over 500 km. Using the heater in winter doesn't affect fuel consumption much, but running the AC in summer adds about 1 liter per 100 km. Overall, it's slightly more fuel-efficient than the Highlander but thirstier than the Lexus NX, given its high-power 2.0T engine. I recommend installing a fuel consumption app to track real data, as the official figures aren't very accurate.

As a car enthusiast, I've studied the fuel consumption performance of the RDX. Its 10AT transmission is tuned for sportiness, resulting in relatively high fuel consumption in stop-and-go city driving, typically above 11L. However, it's surprisingly efficient on highways, achieving as low as 6L when cruising at 1500 rpm. The AWD system adds some burden, with combined consumption around 10L. The older 3.5L model had a baseline consumption of 15L, while the new 2.0T shows significant improvement. Actual tests reveal that using 92-octane gasoline consumes about 0.3L more per 100km compared to 95-octane. When compared to the BMW X3 or Mercedes GLC, the RDX delivers equivalent power but consumes about 0.5L more fuel, which can be seen as a compromise for its sporty character. Maintaining tire pressure at 2.5bar helps save fuel.

I usually drive the RDX to pick up and drop off my kids, so here's some practical experience. The fuel consumption of this car is highly dependent on driving style: driving gently in the city consumes just over 10L/100km, while stepping on the gas pedal hard when in a hurry can push it up to 14L/100km. It's more fuel-efficient than most SUVs on the highway, maintaining a speed of 110 km/h consumes just over 8L/100km. Using the AC in summer adds about 1L/100km, and the auto start-stop feature really saves fuel—don't turn it off. When the fuel tank indicator lights up, you can still drive about 60 km, so don't panic. Over three years, I've driven 40,000 km, with the dashboard showing an average fuel consumption of 9.6L/100km, and actual measurement at 10.1L/100km—not much difference. Fuel consumption drops by about 0.3L/100km after , and a dirty air filter significantly increases fuel consumption.

Just test drove the new RDX last week with a special focus on fuel consumption. The test car's instrument panel showed a historical combined fuel consumption of 10.2L, which is close to the official data. After 20 minutes of driving in congested urban areas, the fuel consumption rose from 9.8L to 12.3L. It dropped to around 7L when cruising at 80km/h on the elevated highway. The salesperson mentioned that feedback from existing customers indicates real-world fuel consumption typically fluctuates between 9.5-11.5L. Notably, the intelligent AWD system increases fuel consumption by about 7% compared to the FWD version. The RDX's cylinder deactivation technology actually provides limited fuel savings, while the start-stop system contributes more significantly. In the same price range, the Q5L demonstrates better fuel consumption control.

After reviewing fuel consumption reports from North American owners, the domestic version of the RDX shows slightly higher fuel consumption. Their typical figures are around 9L in urban areas and 7L on highways. Given differences in fuel quality and road conditions, adding 10% is reasonable. This car has a notable fuel consumption characteristic: cold starts are particularly fuel-intensive, with winter short trips reaching up to 15L—the shorter the distance, the higher the consumption. The fuel tank design is somewhat conservative, requiring frequent refueling on long trips. Media tests have shown that fully loaded with air conditioning on mountain roads can reach 14L. It's recommended not to use only 95 octane fuel; mixing in 92 octane has no impact on fuel consumption and saves money. Using 0W-20 oil instead of 5W-30 can save about 0.4L per 100 kilometers.
