What is the fuel consumption of the Citroen C6?
2 Answers
The combined fuel consumption of the Citroen C6 is 6.3-6.4L/100km. Currently, there are 8 models of the Citroen C6 available for sale. The 2021 400THP Comfort Edition has a combined fuel consumption of 6.4L/100km. In the 2020 models, the 360THP Comfort and 360THP Luxury versions both have a combined fuel consumption of 6.3L/100km. The 400THP Premium, 400THP Premium Nappa Edition, 400THP ORIGINS Centennial Limited Edition, 400THP Luxury, and 400THP Flagship versions all have a combined fuel consumption of 6.4L/100km. The above figures are NEDC combined fuel consumption, which is the data measured under the NEDC test cycle. The actual fuel consumption is higher than these values, ranging from 8.0-9.2L/100km. Here are 5 tips to help reduce fuel consumption while driving: When starting the vehicle, use a low gear, gently press the accelerator, and gradually increase speed. Avoid suddenly pressing the accelerator hard, as this can multiply fuel consumption. Gentle acceleration and braking, early braking: While driving, gently press the accelerator to avoid sudden increases in engine RPM and prevent the car from shaking during operation, making it more fuel-efficient. By anticipating road conditions and applying slow, even acceleration or braking, fuel economy can be improved by up to 20%. Maintain proper tire pressure: Keep tire pressure at the manufacturer's recommended level. For every 2 PSI below the recommended value (approximately 0.2 in metric units relative to the standard pressure of 2.4), fuel consumption increases by 1%. Regular vehicle maintenance or inspections: Regular oil changes can reduce carbon buildup (carbon buildup can cause ignition issues, sluggish acceleration, increased fuel consumption, and in severe cases, even cylinder misfires). Regularly check and replace the air filter if dirty, and clean or replace the fuel injectors, spark plugs, and throttle body as per mileage recommendations. Keep windows closed while driving. Driving with windows open increases wind resistance, which in turn increases the resistance the car faces, requiring more power and thus increasing fuel consumption.
I drive a 1.8T Citroën C6, which shows about 10-11L/100km fuel consumption in city traffic jams, and drops to around 7L on highways. During my last road trip with AC on and full load, the actual measured consumption was 8.2L/100km. This is normal for a mid-size sedan of this size, especially considering its 1.6-ton curb weight. The fuel consumption was alarmingly high when I first got the car, but improved significantly after the first maintenance. Now at 30,000 km, it's basically stabilized. My advice is not to obsess over the dashboard display - calculating over two full tanks gives the most accurate reading.
