What is the actual fuel consumption of BYD Qin hybrid without charging?
3 Answers
BYD Qin hybrid's actual fuel consumption without charging is around 7L. Here is some extended information: Regular maintenance: Regular maintenance can reduce the car's failure rate and also lower fuel consumption. Maintenance includes regularly replacing parts such as spark plugs, oil filters, brake fluid, radiator coolant, air filters, steering fluid, transmission fluid, etc. Keeping the vehicle in optimal condition helps reduce fuel consumption. Notes: Heavy acceleration only shortens driving time by 4%, but increases fuel consumption by 37%-40%. On general urban roads, the speed is usually maintained at 50 km/h, with engine RPM around 2000-2500; on highways, the speed is usually between 90-110 km/h, and for every 10 km/h increase in speed, fuel consumption increases by 10%. Reason: Because RPM is the biggest factor affecting fuel consumption; Reducing weight: For every 100KG increase in vehicle weight, fuel consumption increases by 4%~5%.
I've been driving the Qin PLUS DM-i for almost a year now, basically using it as a conventional fuel vehicle without charging. My daily commute involves mostly congested urban roads, with the displayed fuel consumption consistently ranging between 4.2-4.5 liters. Surprisingly, it rises slightly to just over 5 liters when driving on highways. The most pleasant surprise is how frequently the electric motor kicks in during low-speed city driving - starting from traffic lights feels smoother than gasoline cars while being more fuel-efficient. Running the AC at 26℃ has minimal impact on fuel economy, adding only about 0.3 liters when fully loaded. The 45-liter fuel tank provides a range of 900-1,000 km when full, working out to just over 0.3 yuan per kilometer - nearly half the cost of my previous 1.6L Sylphy. Of course, driving habits play a role too; I typically use ECO mode and apply the accelerator gently.
As a hybrid car owner, I believe the key to the Qin's fuel consumption without charging lies in its operating logic. When the battery is low, its DM-i system prioritizes the engine generating electricity to power the motor, functioning like a range extender in low-speed urban driving, thus keeping consumption around 4 liters. On highways, the engine directly drives the wheels, increasing consumption to 5.5 liters, but it's still over 20% lower than comparable gasoline cars. I once conducted a specific test, driving 280 kilometers round trip from Beijing to Tianjin without air conditioning, achieving a combined consumption of 4.8 liters. However, temperature effects should be noted; in winter below zero, battery activity decreases, increasing consumption by about 0.5 liters, while it remains stable in summer. Frequent hard acceleration might push the displayed consumption above 6 liters.
