The 2.4-liter Tucson is powered by Hyundai’s Theta II 2.4L inline-4 gasoline engine. It typically makes about 170–176 hp and 168–169 lb-ft of torque, with exact figures varying by model year and market.
Engine family and core specs
The 2.4L engine is part of Hyundai's Theta II family, a naturally aspirated 2.4-liter inline-4 with double overhead cams and variable valve timing. It uses multi-point fuel injection and is designed to balance reasonable fuel economy with solid pulling power for a compact SUV. In the Tucson, it has appeared with different transmissions over its lifespan, including automatic options and, in some markets, a manual transmission.
Model-year availability and regional variations
Availability of the 2.4L option is tied to generation and market. In the United States, the 2.4-liter engine appeared in earlier second-generation Tucsons (roughly model years around 2010–2012), while newer Tucsons generally shifted to smaller engines or turbocharged setups. Outside North America, the 2.4L has been more commonly offered in various trims and generations. If you're shopping used, always verify the exact engine code and output for your specific VIN.
Notes on maintenance and reliability
As with any engine, keeping up with scheduled maintenance is crucial. The Theta II 2.4L uses a timing chain, not a belt, but oil and cooling-system maintenance remains essential to long-term reliability. When inspecting a used Tucson with this engine, check for typical wear items on a 2.4L four-cylinder, such as seals and gaskets, and ensure the cooling system and fuel-injection components are in good condition.
Summary
In short, the Tucson's 2.4-liter variant is powered by Hyundai’s Theta II 2.4L inline-4 gasoline engine, delivering roughly 170–176 hp depending on year and market. Availability varies by generation and region, so buyers should confirm the exact specifications for their vehicle’s year and market.
