EPA Fuel Economy: 35/40 mpg
The Hyundai Sonata hybrid shares most of its mechanical components with the Kia Optima, so it should come as no surprise that the Hyundai has the same horsepower and fuel-economy ratings as the Kia. As a result, the Sonata hybrid carries a sticker price that’s a marginal $175 more expensive than that of the Optima hybrid.
The main difference between the two cars concerns design. Though the Optima hybrid looks only mildly different than traditional models, the Sonata hybrid takes wears a drastically different face. Instead of the elegant chrome waterfall grille on other versions, the hybrid has a gaping black plastic grille. Aerodynamic five-spoke wheels and clear taillights also distinguish the hybrid from normal Sonata models.
