The Hyundai Elantra Hybrid is powered by a 1.6-liter Atkinson Cycle four-cylinder gasoline engine and an electric motor integrated into its 6-speed dual-clutch automatic transmission. The engine and electric motor combined produce 139 total system horsepower and 195 pound-feet of torque,
In our 2022 Elantra Hybrid Limited its rated by the EPA at 19 mpg city, 52 mpg highway and 50 mpg combined. The base Blue models are rated higher at 53 mpg city, 56 mpg highway and 54 mpg combined – a difference mostly attributed to its smaller tire width.
The engine itself is composed of an aluminum block and head with variable valve timing. Electrical power is provided from a 240V 1.32 kWh Lithium-ion battery mounted underneath the rear seat along with a 12V accessory battery in the same location. Thus, you won’t find a 12V battery here in the engine compartment.
Following the airflow, the intake charge starts at the front just above the radiator and makes its way to a cleverly design intake plenum and filter assembly mounted atop the engine itself. Air then travels down to the plastic composite intake manifold just below it at the front of the engine.
Once the combustion process is complete, the exhaust exits at the rear of the engine directly into the catalyst assembly.
Doing your own service and maintenance on the Elantra Hybrid is much like any other car. The first and most important item of note is that you should avoid handling the bright orange high-voltage wiring associated with the electric drive and control system. If you don’t know what you are doing and mishandle these components you can be killed.
That aside you can find the engine coolant reservoir at the passenger side of the engine compartment seen by its bright pink coolant. Just ahead of that on the passenger side is the windshield washer reservoir.
Checking the engine oil is done nearby at the passenger side front of the engine, the bright yellow dipstick highly visible. The oil filler cap is located nearby at the top of the engine. The air filter is mounted at the top of the engine, you can see our separate video linked below in the information on how to replace it.
The brake fluid reservoir is found at the driver side rear of the engine compartment. Notable is that Elantra Hybrid uses and electronically controlled brake system instead of a traditional powerbooster and cylinder.
Nearby is the engine ECO and to its right is the main fuse box where you can also find the main 12V access point. Here, Hyundai has provided a handy fuse removal tool. If you are looking for a place to jump-start the Elantra Hybrid, read your manual first regarding the 12V reset button and procedure.
Lastly, the coolant reservoir for the high-voltage electrical control systems can be found at the driver side front of the engine compartment. It uses the same coolant as the engine and can be topped off and managed much the same.
