The 2018 Civic LX is not turbocharged; it uses a 2.0-liter naturally aspirated engine.
In the 2018 lineup, Honda offered two engine options across Civics: a 2.0L inline-four in the LX and base trims, and a 1.5L turbo in the Sport, EX, EX-L, and Touring trims. The LX’s 2.0L engine delivers 158 horsepower and 138 lb-ft of torque and can be paired with either a 6-speed manual or a CVT. The turbocharged 1.5L engine, found in the higher trims, typically produces about 174 horsepower and 162 lb-ft of torque with a CVT; the performance-oriented Si uses a specially tuned 1.5L turbo that makes 205 horsepower and 192 lb-ft of torque.
Engine options across the 2018 Civic trims
For quick reference, here is a breakdown of which trims use the 2.0L naturally aspirated engine and which use the 1.5L turbo.
- LX: 2.0L naturally aspirated engine (not turbo)
- Sport: 1.5L turbo
- EX: 1.5L turbo
- EX-L: 1.5L turbo
- Touring: 1.5L turbo
- Si: 1.5L turbo tuned to 205 hp
In short, if turbo power is a priority, the LX will not meet that requirement; consider Sport, EX, EX-L, Touring, or the Si for higher performance.
Summary
The 2018 Honda Civic LX is not turbocharged. It relies on a 2.0-liter engine, while turbocharged power is available in higher trims with the 1.5-liter turbo engine. For the most spirited version, the Civic Si uses a more aggressively tuned turbo engine with 205 horsepower. Overall, the LX serves as the non-turbo entry point in the 2018 Civic lineup.
