What is the actual fuel consumption of the 2021 Passat?
2 Answers
The actual fuel consumption of the new Passat is 6.8L/100km; overall, it performs quite well in terms of fuel efficiency. However, in real-world driving conditions, fuel consumption is influenced by multiple factors, so the specific fuel consumption should be based on actual usage. Main factors affecting fuel consumption: Spark plug carbon deposits: If spark plugs accumulate excessive carbon deposits or become worn out, it can lead to decreased ignition energy and stability, resulting in increased fuel consumption. Intake system cleanliness: Its cleanliness directly affects the engine's performance, thereby impacting fuel consumption. Special attention should be paid to the air filter and throttle body. Fuel injector cleaning: The quality of fuel atomization from the injectors directly affects engine combustion, leading to higher fuel consumption. Experts recommend cleaning the fuel injectors approximately every 60,000 kilometers. Tire pressure monitoring: Low tire pressure increases the contact area between the tires and the road surface, which not only raises fuel consumption but also causes damage to the tire sidewalls. Additionally, it poses a risk of tire blowouts during high-speed driving, so maintaining proper tire pressure is essential.
Last time I drove my friend's 2021 Passat on a long trip, I paid special attention to the fuel consumption. The 1.4T version is indeed fuel-efficient on the highway, with cruise control keeping it just over 6L/100km, but during rush hour traffic in the city, it can spike to over 9L. I also tried the low-power 2.0T version—driving gently gives a combined fuel consumption of around 8.5L, while aggressive driving pushes it close to 10L. I’ve heard some experienced drivers can get it down to 7.5L using eco mode and anticipating road conditions, but my foot isn’t that light. The 66L fuel tank is quite spacious, but with the recent price hikes for 95-octane gas, watching the meter tick up during refueling is painful. Oh, and the heater really guzzles fuel in winter, especially on short commutes, where it can add over 1L to the consumption.
