The fuel consumption of the 2021 Elantra is 5.40L/100KM. Below is some extended information on the topic: 1. Fuel consumption generally refers to constant-speed fuel consumption: Constant-speed fuel consumption is the vehicle's fuel consumption per 100 kilometers obtained in the constant-speed driving fuel consumption test specified by national standards for certain types of vehicles. 2. Types of vehicles: M1 category, M2 category with a maximum design total mass not exceeding 3.5t, and N1 category compressed natural gas vehicles; M1 category and N1 category vehicles with a maximum design total mass not exceeding 3.5t, tested according to the method specified in GB/T-12545.1-2008 'Test methods for fuel consumption of passenger cars'; M2 category, M3 category, and N2 category, N3 category compressed natural gas vehicles with a maximum design total mass exceeding 3.5t; M2 category, M3 category, and N category vehicles with a maximum total mass greater than or equal to 2t, tested according to the method specified in GB/T-12545.2-2001 'Test methods for fuel consumption of commercial vehicles'.

Having driven the 2021 Elantra for almost two years, the fuel efficiency has been quite good overall. The gasoline version averages around 33 to 35 miles per gallon (mpg) combined. In city traffic with congestion, it drops slightly to about 28 mpg, while highway cruising easily exceeds 38 mpg. The hybrid version performs even better, achieving a combined 48 to 50 mpg, making it particularly economical. I've noticed that driving habits significantly impact fuel consumption—gentle acceleration, maintaining tire pressure at 32 PSI, and regular oil changes can optimize fuel efficiency by about 5%. Fuel consumption increases slightly when using air conditioning in summer, and cold starts in winter also consume a bit more. Checking the vehicle's condition before long trips is a good practice, as a well-maintained car ensures efficient operation.

What Causes White Smoke and Water Dripping from the Exhaust of a Diesel Engine?

White smoke and water dripping from the exhaust of a diesel engine indicate that the coolant from the radiator has entered the engine interior, usually due to a damaged cylinder head gasket. Coolant, also known as antifreeze coolant, prevents the cooling liquid from freezing during cold winter parking, which could otherwise crack the radiator or damage the engine cylinder block. Many people believe that antifreeze is only used in winter, but in fact, it should be used year-round. A diesel engine is an engine that burns diesel fuel to release energy, with advantages including high torque and good fuel economy. The working process of a diesel engine shares many similarities with that of a gasoline engine, with each working cycle also going through four strokes: intake, compression, power, and exhaust.
