The 2018 Accord is the 10th generation of Honda's perennially best-selling midsize sedan. All new from the ground up, the new Accord is built on a new platform with a lower, wider stance, a lighter and more rigid unibody structure; a lighter and more sophisticated chassis; three advanced new power units, including Honda Accord's first-ever turbocharged engines, a new 10-speed automatic transmission and a third-generation two-motor hybrid system.
