TCC’s Bottom Line
The 2018 Kia Optima Hybrid is a fuel-efficient pick among mid-sizers that doesn’t wear its eco credentials on its sleeves. The 2018 Mazda 6 is a stylish, good handling sedan that finally has the underhood muscle to match. The 2018 Volkswagen Passat does little wrong, but its stoicism means it isn’t much fun.
