The engine most commonly found in the 2012 Hyundai Elantra is a 1.8-liter inline-four gasoline engine, delivering about 148 horsepower.
In the United States, this 1.8-liter engine powers the majority of trims, with a choice of a six-speed manual or a six-speed automatic transmission. In some international markets, Hyundai offered a larger 2.0-liter inline-four engine on certain Elantra variants. This article outlines the main engine options for the 2012 model year and how they were deployed across markets and trims.
Engine options by market and trim
Below are the primary engine configurations that appeared on the 2012 Elantra, noting which were standard in the U.S. and where the alternatives were available.
- 1.8-liter inline-4 gasoline engine (part of Hyundai's Gamma family) producing approximately 148 horsepower and 131 lb-ft of torque. Paired with either a six-speed manual or a six-speed automatic transmission, depending on trim.
- 2.0-liter inline-4 gasoline engine (Nu family) available on select overseas markets and trims. This larger engine offered higher output for buyers outside the U.S. market.
In practice, most U.S.-market 2012 Elantras used the 1.8L engine with standard transmission choices, while the 2.0L option was not widely offered domestically but appeared in some international configurations.
Performance and efficiency
Fuel economy and performance varied by engine and transmission. The 1.8L model generally provided competitive efficiency for its class, with mpg figures differing slightly between the manual and automatic transmissions and by driving conditions. The 2.0L variant, when available, offered more power, typically at a modest sacrifice to fuel economy.
Summary
Overall, the 2012 Hyundai Elantra’s standard engine was a 1.8-liter inline-4 gasoline powerplant delivering about 148 hp, mated to either a manual or automatic transmission. A larger 2.0-liter engine existed, but primarily in non-U.S. markets. This combination made the Elantra a practical choice in its year, balancing balanced performance with fuel efficiency.
