For 2021 the all-new redesigned Hyundai Elantra base engine is a 2.0 liter naturally aspirated Atkinson Cycle four cylinder as equipped in trim grades SE, SEL and Limited as we have here. This engine has been used in the Hyundai Elantra since 2017.
As equipped here in the Limited model with a continuously variable transmission Hyundai calls IVT, 2.0 liter engine is rated by the EPA at 31 mpg city, 41 mpg highway and 35 mpg combined rating. The base model SE is rated slightly higher as it has an idle start-stop system.
It’s rated at 147 horsepower at 6,200 rpm and 132 pound-feet of torque at 4,500 rpm. Being an Atkinson engine, it can delay intake valve timing to maximize the expansion ratio which is combined with a relatively high compression ratio of 12.5:1.
Like many in its class now it has an electronically controlled thermostat that allows the computer to micromanage the engine’s temperature for better fuel efficiency.
Following the airflow, the intake charge starts up front at the air-box that breathes through a snorkel behind the front grille. It then travels down to a throttle body mounted low and into a composite plastic intake manifold with two-step operation.
Though it has modern features like variable valve timing for its twin cams, it still does its job with port fuel injection instead of the direct-injection that is sweeping the industry. This is likely one of the reasons for its rather quiet and refined operation we experience on our recent test drive.
For servicing, the engine compartment is simple and well laid out. The brake fluid reservoir is located at the rear driver side of the engine bay. Next to it is the 12-volt battery and adjacent to it is the main fuse block. Access fuses by removing the plastic cover. A fuse removal tool is provided just inside.
Windshield washer fluid and coolant are right up front on the passenger side and to the middle. Note that access to the alternator and AC recharging ports is also quite good.
Checking and filling the oil also a snap with both the cap and the dipstick clearly seen up on top of the engine. With the engine beauty cover removed you can see the coil packs for the spark plugs which can be serviced with easy access.
The air filter element is located inside the main filter box at the driver side front of the engine compartment. Changing the filter is a quick and easy process accomplished by popping two metal spring clips and lifting the box top away.
Simply remove the filter element to check or replace. Reverse the process to install filter, assuring the rear tabs of the box cover are aligned for proper sealing and latching down with the metal clips. Just be sure not to scrape your new filter element on the metal clips or pinch it in the box cover.
