In 2010, the Honda Civic offered several engine options depending on trim and market: a standard 1.8-liter inline-4 for most models, a higher-output 2.0-liter inline-4 for the Civic Si, and a hybrid powertrain pairing a small gas engine with an electric motor. A limited natural gas GX version was also available in select markets.
Engine options by trim
Below are the main engine configurations that appeared in the 2010 Civic lineup, with the typical specs associated with each powerplant.
1.8-liter inline-4 (LX, EX, EX-L)
Before listing the key specs, note that this is the standard engine for most non-Si Civics in 2010, prioritizing a balance of performance and efficiency.
- Displacement: 1.8 L
- Configuration: inline-4
- Valvetrain: i-VTEC
- Horsepower: about 140 hp
- Torque: about 128 lb-ft
The 1.8-liter engine served as the core powertrain for the majority of Civics in the 2010 model year, delivering reliable everyday performance.
2.0-liter inline-4 (Civic Si)
Next, the performance-focused Si variant used a more powerful engine designed for heightened responsiveness and sportier driving dynamics.
- Displacement: 2.0 L
- Configuration: inline-4
- Valvetrain: i-VTEC
- Horsepower: around 197 hp
- Torque: around 139 lb-ft
This engine is paired with a 6-speed manual transmission and underpins the Civic Si’s sporty character.
Civic Hybrid: 1.3-liter gas engine with IMA
For efficiency-focused buyers, the Civic Hybrid combined a smaller gasoline engine with an electric motor as part of Honda’s Integrated Motor Assist system.
- Gasoline engine: 1.3 L i-VTEC inline-4
- Hybrid system: IMA electric motor
- Combined horsepower: around 110 hp
The hybrid powertrain emphasizes fuel economy over outright acceleration, appealing to efficiency-minded drivers.
Civic GX: natural gas version (limited markets)
A limited natural gas version existed in select markets, built on a standard 1.8-liter platform but modified to run on compressed natural gas (CNG).
- Engine: 1.8 L i-VTEC adapted for CNG
- Fuel: compressed natural gas
- Availability: limited to certain fleets/markets
The GX variant offered an alternative fuel option for buyers in regions with CNG infrastructure.
Summary
The 2010 Honda Civic’s engine lineup covered a broad spectrum: a common 1.8-liter inline-4 for most trims, a stronger 2.0-liter inline-4 for the Civic Si, and a hybrid system combining a 1.3-liter gasoline engine with an electric motor for improved efficiency. A rare GX variant used a CNG-modified 1.8-liter engine in limited markets. This mix allowed buyers to choose based on performance, efficiency, or alternative-fuel considerations.
