The 2018 Honda Civic is not powered by a V6 engine. It uses four-cylinder power across its lineup.
In 2018, Honda offered two main four-cylinder engines for the Civic: a 2.0-liter naturally aspirated inline-4 in the base models and a 1.5-liter turbocharged inline-4 in higher trims. The performance-focused Civic Si and Civic Type R also rely on four-cylinder engines, but with higher-output tuning. There was no production Civic with a V6 engine in 2018.
Engine options in the 2018 Civic lineup
These are the principal engine choices that were available for Civics in 2018, illustrating how the model stayed with four-cylinder power rather than a V6.
- 2.0-liter inline-4 engine used in the base Civic models (LX, Sport)
- 1.5-liter turbocharged inline-4 engine used in higher trims (EX-T, EX-L, Touring)
- Civic Si — performance variant powered by a turbocharged 1.5-liter four with a 6-speed manual transmission
- Civic Type R — high-performance hatch with a turbocharged 2.0-liter inline-4 and a 6-speed manual transmission
In short, none of the 2018 Civic variants used a V6 engine. If you are seeking a Civic with significant power, consider the Si or Type R, both four-cylinder models designed for performance without a V6 configuration.
Summary
Bottom line: No V6 options exist for the 2018 Honda Civic. The model relied on four-cylinder engines throughout its lineup, with the Si and Type R offering enhanced performance via turbocharged four-cylinders rather than any V6 configuration. For a V6-powered Honda, you would look to other models in the brand's lineup from that era.
