Looks/Style Ranked 2018 Honda Accord 2.0T Touring FWD better.
"The brand new Accord is every bit a luxury vehicle with a Honda emblem. From the stylish looks on the outside, the massive performance upgrades under the hood, and the elegant design and features inside, it blows away the rest of the competition! This is not even a question! Once you test drive the Accord and see the performance of being in sport mode and then switch over to econ mode for a more relaxed ride you will clearly see how this vehicle is hands down the car of the year. "
Family Car Ranked 2018 Honda Accord 2.0T Touring FWD better.
"More spacious, safer, and a smoother ride! I was able to quickly and easily put both car seats in the backseat of the Accord and neither of my daughters were kicking the back of the front seats, which theyre easily capable of doing in the Kia and even my Odyssey! They loved being able to see the navigation screen from the backseat and their comfort made choosing the Accord an easy decision. "
