vehicles do not consume much fuel, with an average fuel consumption of 7 liters per 100 kilometers. Below are the specific reasons for high fuel consumption in cars: 1. Affected by Temperature: Fuel consumption fluctuates due to temperature changes. In winter, when temperatures are low, fuel consumption tends to increase slightly. 2. Lack of Regular Maintenance: Dirty engine oil and air filters can also lead to increased fuel consumption. Dirty oil results in poor lubrication, increasing resistance in the engine's moving parts, which requires more energy to overcome, thus raising fuel consumption. 3. Excessive Carbon Buildup: Carbon deposits commonly accumulate in the throttle body, fuel injectors, intake manifold, and piston tops. Excessive carbon buildup in any of these areas can cause incomplete combustion, leading to higher fuel consumption.

I've driven several cars, including both 1.4T and 2.0T models. Fuel consumption does increase in city traffic jams, especially for older models. But on highways, they're truly fuel-efficient - my Passat only consumes just over 6 liters per 100km on highways. The turbocharged engines paired with DSG transmissions are quite intelligent, maintaining steady throttle can effectively control fuel consumption. The later hybrid versions are even more economical - my neighbor's Tiguan L PHEV can run 50km on pure electric power. Actually, Volkswagen's fuel consumption is average among its peers - German cars are heavier but have lower drag coefficients. For daily use, monthly fuel costs are around 800 yuan, mainly depending on how heavy your right foot is.

Our Lavida has been running for five years at home, with all fuel consumption records kept. The 1.5L automatic transmission model consumes 11L/100km in pure urban driving with AC on during summer, dropping to 9L when AC is off in spring/autumn. The most fuel-efficient scenario is maintaining 60km/h steady speed on national highways, achieving a tested 5.3L/100km. Fuel consumption decreases by about 0.5L after the first for new cars, and switching to full synthetic oil also helps. Once when spark plugs needed replacement but weren't changed in time, consumption suddenly soared to 13L/100km. The new 1.5T+48V mild hybrid version is much more economical than our old model - a friend's new Golf only consumes 8L in urban driving.

After 20 years of car repairs, I've found that the key to Volkswagen's fuel consumption lies in . I've seen customers with high fuel consumption in their Bora, which dropped by 2 liters immediately after replacing the oxygen sensor. Regular carbon cleaning for the EA211 engine is crucial; cleaning the throttle body every 30,000 kilometers can save fuel. Never overlook tire pressure, as underinflated tires can increase fuel consumption by 5%. Cars with auto start-stop do save fuel at red lights, but frequent starts can easily damage the battery. Using 95-octane fuel burns more efficiently than 92-octane, but the cost per kilometer is actually about the same.

Comparing Japanese, German, and American cars, Volkswagen's fuel consumption performance is quite balanced. The difference in fuel consumption between the Sagitar and Civic is only about 0.5 liters, but the chassis quality is significantly better. The newly released 1.5T EVO engine features cylinder deactivation technology, allowing two cylinders to shut off at constant speeds. Recently, while testing the Lamando L for a client, I was shocked to see a fuel consumption of 4.9L at a steady 80 km/h on urban expressways. Remember not to pile up junk in the trunk—every 100 kg of extra weight increases fuel consumption by 7%.

Recently tested fuel consumption for ten company cars, with the Tharu 1.5T being quite representative. With AC on in congested traffic, actual measurement was 10.2L/100km, while highway cruising only required 5.8L. The hybrid version of the Tayron was even more impressive, consuming just 5L in city driving when fully charged. Be careful not to overfill the engine oil, as exceeding the upper limit on the dipstick can increase fuel consumption. For those who primarily drive short distances, it's recommended to take a highway trip each quarter to clear carbon deposits. In winter, avoid idling to warm up the engine for more than 1 minute; driving gently while warming up is more fuel-efficient.
