No—the 2018 Civic Sport does not have a turbocharged engine; it uses a 2.0-liter naturally aspirated inline-four. Turbocharged power is available in other trims of the Civic lineup, such as those with the 1.5-liter turbo engine.
To understand what that means, it helps to look at how the 2018 Civic lineup was organized and which engines paired with which trims. The Sport sits in the lower-to-mid range of the lineup and is distinguished by its naturally aspirated powertrain, while the turbocharged 1.5-liter engine powers several higher trims and the sportier Si variant in the broader Civic family.
Engine options by trim (2018 Civic US)
Before listing the engines, here is a quick overview of which trims typically paired with which engine in the 2018 Civic lineup.
- 2.0-liter inline-four, naturally aspirated: about 158 horsepower and 138 lb-ft of torque; used in the LX and Sport trims, with transmission options including a 6-speed manual or CVT depending on configuration.
- 1.5-liter turbocharged inline-four: around 174-180 horsepower with 162-177 lb-ft of torque; used in higher trims such as EX-T, EX-L, and Touring, typically paired with a CVT and offering strong mid-range torque.
In short, the Sport trim itself does not employ the turbocharged 1.5-liter engine; turbo power is found in other Civic trims. For fans of a turbocharged drive, the higher trims (EX-T, EX-L, Touring) are the ones to target in 2018.
Notable performance differences between NA and turbo engines
The two engine families deliver distinct character. The 2.0-liter NA is simple, reliable, and adequate for everyday driving, with predictable response and typically a more linear power delivery. The 1.5-liter turbo offers stronger torque at lower RPM and a more responsive feel in acceleration, especially at highway speeds, but it can come with different fuel economy characteristics depending on driving style and transmission choice.
What this means for buyers and drivers
Understanding which engine powers which trim helps buyers set expectations for performance, fuel economy, and price. If you want turbocharged acceleration and you’re shopping for a Civic, you’ll want to compare the EX-T, EX-L, or Touring trims (and potentially the Si in the broader Civic family) rather than the Sport.
Summary
The 2018 Honda Civic Sport does not have a turbocharged engine. It relies on a 2.0-liter naturally aspirated engine, delivering sufficient power for everyday driving with the Sport’s own character. If turbo power is a priority, look to the higher trims with the 1.5-liter turbo or to other performance-focused variants in the Civic family.
