Why is the Elantra's fuel consumption high?
2 Answers
Possible reasons include damaged spark plugs. Worn spark plugs can reduce ignition energy, causing uneven combustion of the air-fuel mixture, which leads to slower acceleration and increased fuel consumption. Below are relevant explanations about fuel consumption: 1. Fuel consumption per 100 kilometers: This refers to the fuel consumed when a vehicle travels 100 kilometers at a certain speed on the road. It is a theoretical indicator for vehicles. Manufacturers measure this value under controlled conditions using a dynamometer installed on the vehicle chassis, converting it into speed parameters, then calculating the theoretical experimental fuel consumption data per 100 kilometers for the model. 2. Road condition fuel consumption: This is a fuel indicator calculated based on values obtained from repeated tests where vehicles drive specified roads at regulated speeds and times. Also called multi-condition road cycle fuel consumption, the standard specifies that each cycle includes various driving conditions, recording parameters such as gear shift timing, parking duration, driving speed, acceleration, braking, and deceleration. This method yields values closer to real-world conditions.
I drive a lot and noticed a sudden increase in fuel consumption, so I checked if it was due to my driving habits. Friends who like to accelerate and brake aggressively, take note: every time you stomp on the gas pedal, the engine's fuel injection volume surges, and the fluctuating RPMs consume a lot of fuel. Frequent starting and braking in city traffic also burns more fuel—maintaining a steady speed of 60 km/h is the most economical. I previously adjusted my driving style by anticipating red lights and easing off the throttle early, as well as keeping windows closed on highways to reduce wind resistance, which directly lowered my fuel consumption by 2%. Using the air conditioning and compressor can also increase fuel consumption by about 10%, so for short trips, it's better to roll down the windows for ventilation. Underinflated tires increase rolling resistance, forcing the engine to work harder, and a trunk full of heavy items also consumes more fuel.
