The DOHC inline-4 engine, code-named Theta, debuted this year in the 2009 Hyundai Sonata sedan, where it makes 175 hp and 168 lbs-ft of torque.

The engine is will be available with a six-speed automatic transmission. In a Sonata with an automatic transmission, the new engine returns 22 mpg city and 32 mpg highway.

Also, starting 2010 or 2011 the Tucson will also be offered with four-cylinder engines.
