The 2012 Kia Sorento engine is the heart of this versatile midsize SUV, offering a balance between everyday usability and solid performance. That year, Kia offered two primary engines: a 2.4-liter inline-four producing 175–191 horsepower and a 3.5-liter V6 generating up to 276 horsepower. Both engines were paired with a six-speed automatic transmission, designed to provide smooth shifts and reliable power delivery across city and highway driving.
