What is the fuel consumption per 100 kilometers for a 2.5L engine?
3 Answers
The fuel consumption per 100 kilometers for a 2.5L engine is generally between 13 to 15 liters. Fuel consumption per 100 kilometers refers to the amount of fuel a vehicle consumes when traveling 100 kilometers on the road at a certain speed. It is a theoretical indicator for vehicles. Manufacturers measure this value in an objective environment using a dynamometer installed on the vehicle's chassis, converting it into speed parameters, then specifying the speed to calculate the theoretical experimental fuel consumption data per 100 kilometers for the vehicle model. Summer air conditioning system check: Air conditioning malfunctions are a significant cause of high fuel consumption. Poor cooling performance can lead to increased fan speed and lower temperatures to achieve a cooling effect. Frequent hard braking: Frequent hard braking is a major reason for persistently high fuel consumption in cars. While ensuring safe driving, make full use of the vehicle's inertia. Small-displacement vehicles should not use air conditioning too aggressively: For vehicles exposed to the sun, it is not advisable to turn on the air conditioning immediately after getting in. First, open the windows and set the fan to a higher setting without turning on the air conditioning to expel the hot air inside. Wait until the vehicle has cooled down moderately before turning on the air conditioning.
I drive a 2.5L Camry Hybrid myself, and for daily city commuting, it averages around 5.8L per 100km. On the highway with cruise control, it can drop to 5.2L. But fuel consumption is really unpredictable—my buddy drives a Highlander with the same displacement and it guzzles over 9L. The biggest factor is actually driving technique; aggressive acceleration and braking can instantly spike fuel consumption by 2-3 points. Running the AC at full blast in summer is most noticeable, burning about 1L more than usual. Cold starts in winter are also particularly fuel-heavy. Tire pressure matters too—once when my tires were underinflated on a long trip, it directly added 0.7L per 100km.
This was a common question from customers at the repair shop. We've tested over a dozen 2.5L displacement vehicles. Sedans generally consume between 8 to 10 liters, with midsize cars like the Teana averaging around 9.5L in urban areas. However, SUVs are completely different - 4WD models like the RAV4 start at 11L. Engine technology makes a huge difference; Mazda's Skyactiv can achieve as low as 7.8L, while older naturally aspirated engines typically exceed 10L. Pay attention to oil viscosity too - some owners reported a 1.2L increase after switching to higher viscosity oil. Regular maintenance is key for fuel efficiency - vehicles with severe carbon buildup can consume 15% more fuel.
