The 2018 Honda Accord strikes out on a different path for mid-size sedans this year. The Accord eschews the typical formula of 4- and 6-cylinder engine choices for a trio of inline-4s.
The base engine is a 1.5-liter turbo-4 borrowed from the smaller Civic sedan. The EPA rates it at 30 mpg city, 38 highway, 33 combined when paired to the continuously variable transmission. That's good enough for an 8 out of 10 on our ratings scale. (Read more about how we rate cars.)
A larger, 2.0-liter turbo-4 is available on top-trim models isn't as efficient. When paired to a 10-speed automatic, the EPA rates it at 23/34/27 mpg. In Sport or Touring trims it's rated at 22/32/26 mpg.
Both 1.5-liter and 2.0-liter turbo-4s can be paired with 6-speed manual transmissions, but they’re less efficient than the automatics. The 1.5-liter version manages 26/35/30 mpg, and the 2.0-liter version is rated at 22/32/26.
Sport-trimmed versions are rated slightly lower due to a different wheel-tire combination that prefers style over efficiency.
Early next year, the Honda Accord Hybrid will join the lineup. It pairs a 2.0-liter Atkinson-cycle inline-4 with a two-motor hybrid system and batteries.
It’ll be the efficiency champ, although officials from Honda haven’t yet estimated its fuel economy. Although it’s a new car, it uses the same powertrain as the outgoing generation and should manage roughly the same, if not slightly better, fuel economy than the last version. Last year the Accord Hybrid was rated at 49/47/48 mpg.
