Why the SE rates highest

Lighter, smaller wheels

The SE rides on 16-inch wheels and carries less equipment, which is worth about a mile per gallon against the SEL with the same engine.

The turbo trades a little

The 1.6-liter turbo makes more torque (195 lb-ft) for easier passing, at a 1 mpg cost on the highway versus the 2.5-liter SE.

The hybrids

The 2020 Sonata Hybrid pairs a 2.0-liter engine with an electric motor and a conventional six-speed automatic. The Blue trim's lighter spec earns the 52 mpg combined rating.

The 2026 SEL Sport sits on larger wheels and adds optional AWD, which is why its rating is lower than the 2020 SEL's. The N Line replaced the 1.6 turbo with a 290-horsepower 2.5 turbo.

Keep a used Sonata at its rating

  • Check tire pressure monthly, cold, using the door label. How to find the right pressure.
  • Follow the oil change and air filter schedule in the owner's manual; the turbo engine especially.
  • Use the Smart or Eco drive mode for commuting. Sport mode holds gears longer and costs fuel.
  • Have a check-engine light diagnosed promptly.
