The 2008 Honda Civic offered multiple engine options depending on model and market. The standard gasoline Civics used a 1.8-liter inline-4, there was a high-performance Si with a 2.0-liter engine, and a Civic Hybrid combined a smaller gasoline engine with an electric motor. In short, there isn’t a single engine across all trims.
Gasoline powertrains for standard Civics
Below is a summary of the gasoline engines that powered most 2008 Civics in the United States, along with typical outputs and transmissions.
Engine options and performance
- 1.8-liter i-VTEC inline-4 (R18A1) producing about 140 horsepower and 128 lb-ft of torque; available with either a 5-speed manual or a 5-speed automatic transmission, depending on trim.
- 2.0-liter i-VTEC inline-4 (K20Z3) producing about 197 horsepower and 139 lb-ft of torque; paired exclusively with a 6-speed manual transmission in the Civic Si.
The above outlines the gasoline engines used in the non-hybrid Civics for the 2008 model year, including their common outputs and drivetrain pairings.
Civic Si: the performance engine
The Si variant delivers sport-oriented performance with a specially tuned 2.0-liter engine designed for higher revs and greater power.
- Engine: 2.0-liter i-VTEC inline-4 (K20Z3)
- Power output: approximately 197 horsepower
- Torque: about 139 lb-ft
- Transmission: 6-speed manual (standard on Si)
The Si’s engine is distinctive within the 2008 Civic lineup for its higher output and manual-only transmission, targeting enthusiasts seeking more spirited driving.
Civic Hybrid: gasoline engine with electric assist
The 2008 Civic Hybrid combines a smaller gasoline engine with Honda’s Integrated Motor Assist system to improve efficiency, rather than outright performance.
- Engine: 1.3-liter i-VTEC inline-4 (engine code L13A) paired with Honda's IMA electric motor
- Total system output: about 110 horsepower (combined)
- Transmission: CVT (Continuously Variable Transmission)
- Notes: The hybrid relies on electric assist for efficiency, with the ability to run on electric power at low loads and speeds
In the hybrid, the emphasis is on fuel economy and smooth, quiet operation rather than pure acceleration.
Summary
For the 2008 Honda Civic, engine options varied by model: most Civics used a 1.8-liter i-VTEC engine; the sport-oriented Civic Si used a 2.0-liter i-VTEC engine; and the Civic Hybrid used a 1.3-liter i-VTEC engine with Honda’s IMA electric motor. Buyers could choose based on preferences for performance, efficiency, and features, with distinct powertrains tailored to each trim.
