The 2023 Honda Civic offers two engine options: a 2.0-liter naturally aspirated inline-4 and a 1.5-liter turbocharged inline-4.
In more detail, the base powertrain is a 2.0-liter engine delivering 158 horsepower and 138 lb-ft of torque, while the optional turbocharged 1.5-liter four-cylinder produces about 180 horsepower and 177 lb-ft of torque. The turbocharged engine is used on most mid- and upper-level trims for stronger acceleration, while the 2.0-liter engine serves as the standard configuration on the entry-level models. A high-performance Civic Si variant uses a tuned version of the turbocharged engine, increasing output further.
Engine options
The Civic lineup for 2023 includes two main engine options. Review the details below to understand how they differ and where they appear in the trim levels.
- 2.0-liter inline-4 naturally aspirated engine — 158 horsepower and 138 lb-ft of torque.
- 1.5-liter turbocharged inline-4 engine — 180 horsepower and 177 lb-ft of torque.
In summary, the turbocharged 1.5-liter engine powers most of the higher trims for enhanced performance, while the 2.0-liter engine is used on the base configuration.
Additional notes on performance variants
For completeness, the Civic Si (a performance-oriented version of the Civic) uses a tuned version of the same turbocharged 1.5-liter engine and delivers roughly 200 horsepower. The turbocharged engine is not exclusive to the Si, but the Si version pushes output higher than the standard 1.5-liter setup.
Summary
The 2023 Honda Civic is available with two engines: a 2.0-liter naturally aspirated inline-4 (158 hp, 138 lb-ft) and a 1.5-liter turbocharged inline-4 (about 180 hp, 177 lb-ft). The turbocharged option powers most higher trims, while the base configuration relies on the 2.0-liter engine. A performance variant, the Civic Si, uses a tuned version of the turbocharged engine with higher output.
