2018 Hyundai Sonata: Specs and Features, Reviews, and Most Common Problems

Hyundai has always been known for its safe, practical, and economical vehicles. The 2018 Hyundai Sonata does not stray from this formula. With seven different trim models to choose from, there is a Sonata that is right for you. From the base model Sonata SE to the top trim Sonata Limited, Hyundai’s wide variety for their flagship sedan leaves nothing on the table. However, some have begun to sprout worrying reliability issues. Reviews place the 2018 Sonata under the familiar competitors, but not for what you think.

What kind of engine does the 2018 Hyundai Sonata have?

There are three different engine packages for the 2018 Hyundai Sonata lineup, as noted by MotorTrend. Starting with the most common, coming in four of the seven variants, is the 2.4-liter four-cylinder engine. Available in the SE, SEL, Sport, and Limited trims, this naturally aspirated package offers 185 horsepower and 178 pound-feet of torque.

Secondly, the Sport 2.0T and Limited 2.0T trims share a 2.0-liter turbocharged 4-cylinder engine. The turbocharged models crank out 245 horsepower and 260 pound-feet of torque. Impressive numbers considering these models still get 23 MPG City / 32 MPG Highway. Last but not least, the 2018 Sonata Eco trim houses a 1.6-liter turbocharged 4-cylinder engine. The lack of displacement over the other turbo trims gives the package a five-mile-per-gallon jump in city and highway driving. This does come at a cost, however, as the engine only produces 178 horsepower and 195 pound-feet of torque.

What’s the interior of the 2018 Hyundai Sonata like?
