The Sonata is available in two trim levels: the standard Sonata ($14,999, or $15,499 with an automatic transmission) and the high-trim GLS ($16,999, or $17,499 with the automatic). The two Sonatas are distinguished by some basic mechanical differences, as well as features and equipment.
The standard car is powered by a 2.4-liter inline four-cylinder engine and comes equipped with rear drum brakes. While the 2.4-liter engine makes just 137 horsepower, the GLS comes with a 2.5-liter V6 that produces 170 horsepower without a significant drop in EPA mileage estimates. The GLS also gets four-wheel disc brakes.
