The 7th generation Elantra has a total of 7 models currently on sale. Among them, the 2021 1.5L-CVT-TOP Flagship Edition, LUX Premium Edition, and GLX Elite Edition have an NEDC fuel consumption of 5.4L per 100km. The CVT-GLS Leading Edition has an NEDC fuel consumption of 5.3L per 100km. The 240TGDi-DCT-TOP Flagship Edition, DCT-LUX Premium Edition, and DCT-GLX Elite Edition have an NEDC fuel consumption of 5.2L per 100km. The fuel tank capacity of the 7th generation Elantra is the same for all models, at 47L. The distance that can be covered with a full tank of fuel is as follows: 1.5L-CVT-TOP Flagship Edition, LUX Premium Edition, and GLX Elite Edition can cover a distance of 47/5.4*100=870km with a full tank. The CVT-GLS Leading Edition can cover a distance of 47/5.3*100=886km with a full tank. The 240TGDi-DCT-TOP Flagship Edition, DCT-LUX Premium Edition, and DCT-GLX Elite Edition can cover a distance of 47/5.2*100=903km with a full tank. The fuel consumption of a car is directly related to five major factors: driving habits, the car itself, road conditions, natural wind, and environmental temperature. Specific factors that can increase fuel consumption are as follows: Driving habits: Aggressive driving, such as sudden acceleration, frequent overtaking, and not easing off the throttle before a red light, can increase fuel consumption. The car itself: Cars with larger engine displacements generally consume more fuel than those with smaller displacements because larger displacements usually mean higher power, requiring more gasoline to burn and perform work. Heavier cars also consume more fuel because greater weight requires more driving torque. Road conditions: Driving on dirt roads, muddy roads, soft surfaces, or mountainous roads increases resistance and fuel consumption. Natural wind: Driving against the wind or on windy days increases the car's resistance and fuel consumption. Low environmental temperatures: When the engine block is cold, the gasoline injected during a cold start does not atomize easily, requiring more gasoline to be injected for combustion, which increases fuel consumption. Additionally, at low temperatures, the engine's computer controls the engine to run at higher RPMs to warm up, which also increases fuel consumption.

I've been driving the 7th-generation Elantra for a while now. My actual fuel consumption is about 8-9 liters per 100 km in city traffic, and it easily drops to 6-7 liters on the highway, with an average mixed driving of around 7.5 liters. This is largely related to my driving habits—driving more aggressively increases fuel consumption, while smoother driving saves a lot more fuel. The aerodynamic design is quite scientific, providing a strong sense of smoothness while driving, which helps save fuel. I recommend regularly checking tire pressure and maintaining the engine to prevent buildup of impurities, as this can increase fuel consumption by about half a liter. Overall, I feel this car is quite suitable for commuting—economical, affordable, and stable—a significant improvement over my old car.

I haven't owned my seventh-generation Elantra for long, but its fuel efficiency has truly delighted me. Driving around the city, morning traffic pushes consumption to around 8L/100km, but it easily stays above 7L during other times. Highway trips are even more economical - a recent road trip with friends averaged just 6.5L/100km, saving me considerable money. Actually, fuel economy isn't just about the car; driving techniques matter too. By gently accelerating and avoiding sudden braking, I immediately saw improved mileage. Maintenance isn't complicated either - just regular oil changes and air filter replacements. With lower fuel expenses now, I feel this well-designed car makes daily driving completely stress-free.

The 7th-generation Elantra has decent fuel consumption control. I get around 7.5L/100km on regular roads. The key is its efficient engine - the 1.5L displacement balances power and fuel economy, and the optimized aerodynamic design makes it even more fuel-efficient on highways. After long-term driving, I noticed driving habits make a big difference - maintaining steady speed saves nearly 1L/100km compared to frequent overtaking. Paying attention to the lubrication system and tire pressure during maintenance helps keep consumption low. Overall, this performance meets my expectations for a fuel-efficient car.

What is the purpose of an automotive air conditioning blower?

The function of an automotive blower is to distribute the cold air from the air conditioning evaporator or the hot air from the heater core into the vehicle interior. Below are some details about automotive blowers: 1. The blower primarily consists of the following six components: motor, air filter, blower body, air chamber, base (also serving as an oil tank), and oil drip nozzle. 2. The blower operates via an eccentrically mounted rotor inside the cylinder, where the changing volume between the vanes in the rotor slots draws in, compresses, and expels air. 3. During operation, the pressure difference within the blower automatically delivers lubrication to the oil drip nozzle, which drips into the cylinder to reduce friction and noise while preventing gas backflow. This type of blower is also known as a sliding vane blower.

What are the signs of a bad transmission clutch?

The signs of a bad transmission clutch mainly include the following aspects: First: The vehicle slips, lacks power when starting, and cannot run properly. Second: Abnormal noises during driving, such as a rustling sound inside the transmission. Third: The engine stalls when shifting into gear, or there is a noticeable impact sensation during gear shifting, changing gears, or driving. Additional information: If the transmission is damaged, there will be obvious clunking sounds accompanied by vibrations that can be clearly felt. Furthermore, modern vehicle transmissions are now quite mature, and transmission fluid typically needs to be changed every two years, so it generally does not run low on oil.

How Many Kilometers Should a Vehicle Drive Before Changing Transmission Oil?

There are two scenarios for changing a vehicle's transmission oil, which are: 1. For manual transmission models, the transmission oil should be changed every 60,000 kilometers or every three years. 2. For automatic transmission models, the transmission oil should be changed every 40,000 kilometers or every two years. Additional information: Transmission oil is a crucial component that ensures the normal operation of the transmission. It helps in smoother gear shifting, enhances driving control, provides excellent oxidation resistance for the transmission, reduces rusting of mechanical parts, effectively protects the gear set, minimizes wear and tear of transmission components, and extends the lifespan of the transmission.

What to Do When the Car Washer Nozzle is Clogged?

There are several methods to solve a clogged car washer nozzle: 1. Use a pin or similar tool to unclog it. 2. Clean the nozzle and then spray water a few times. Basic methods for diagnosing common faults in car washers: 1. Washer motor does not run: After pressing the windshield washer button, the washer motor does not run, but the fuse is intact. Possible causes: Open circuit between the fuse box power lead and the washer motor; Open circuit between the washer button switch control lead and the washer motor; Damaged brushes or open circuit in the motor lead; Open circuit in the control switch lead or damaged contacts. 2. Washer runs but sprays weakly or not at all: After pressing the windshield washer button, the washer motor makes a running sound, but the water sprays weakly or not at all. Possible causes: Blocked pipeline between the reservoir and the pump, or clogged nozzle; Slippage between the motor rotor shaft and the pump impeller; Low spring pressure on the brushes, severe dirt on the commutator, partial short circuit in the armature coil, or overly tight pump cover. Pressing the washer button causes the fuse to blow immediately. Faults in the electric washer are often caused by clogged hoses or nozzles. During maintenance, proceed from the outside in and from easy to difficult tasks.

Why is there a gasoline smell when the car just starts?

There are several main reasons why a car emits a gasoline smell upon starting, which are: 1. Aging of the rubber hoses in the gasoline vapor canister (requires replacement). In older vehicles, rubber components in the engine compartment are prone to aging. The rubber hoses connecting the carbon canister to the throttle body can leak into the engine compartment if they age, necessitating timely replacement. 2. Leakage at the gasoline pipe connections (requires tightening/repair). If there is a leak in the gasoline pipes, the gasoline smell may enter the car through the air conditioning system. Leaks usually occur at the joints between pipes, which can be visually inspected by opening the engine compartment hood. Over time, a layer of oily residue will form on the surface if there is a leak, requiring tightening or repair. 3. Reduced sealing performance after disassembling the fuel pump (requires repair). Some car owners may replace or disassemble the fuel pump, and the gasoline smell inside the car could be due to residual substances not being cleaned properly after reassembly. It is best to have a repair shop check if the fuel pump is installed correctly. Generally, disassembling the fuel pump is only necessary when replacing it or addressing related faults. The replacement cycle for a fuel pump is approximately around 100,000 kilometers.
