What Engine Does the 2010 Honda Civic Have?

The 2010 Honda Civic typically comes with a 1.8-liter SOHC i-VTEC inline-four (about 140 hp) in most trims; the performance-oriented Si uses a 2.0-liter DOHC i-VTEC (197 hp), the Hybrid pairs a 1.3-liter gasoline engine with an electric motor (110 hp combined), and the GX runs a 1.8-liter engine tuned for compressed natural gas (about 113 hp). Availability varies by trim and market.

The U.S./Canada Engine Lineup by Trim

Honda offered several distinct powertrains in the 2010 Civic across sedan and coupe body styles in North America. The following list outlines each trim’s engine, key outputs, and transmission pairing so you can match specs to the car you’re looking at.

• DX, LX, EX, EX-L (Sedan/Coupe): 1.8-liter SOHC i-VTEC inline-4 (engine code R18A1), approx. 140 hp at 6,300 rpm and 128 lb-ft at 4,300 rpm; 5-speed manual or 5-speed automatic.
• Si (Sedan/Coupe): 2.0-liter DOHC i-VTEC inline-4 (engine code K20Z3), 197 hp at 7,800 rpm and 139 lb-ft at 6,100 rpm; close-ratio 6-speed manual with helical limited-slip differential.
• Hybrid (Sedan): 1.3-liter SOHC i-VTEC inline-4 (LDA) with Integrated Motor Assist (electric motor), combined output about 110 hp and 123 lb-ft; continuously variable transmission (CVT).
• GX (Natural Gas Sedan): 1.8-liter inline-4 adapted for CNG, about 113 hp and 109 lb-ft; 5-speed automatic; ultra-low emissions configuration.

These configurations covered the breadth of Civic buyers in 2010, from efficient commuting (Hybrid, GX) to mainstream daily driving (1.8L) and sport-focused performance (Si).

Technical Notes and Characteristics

Beyond basic specs, several engineering details distinguish the 2010 Civic’s engines. The points below summarize technologies, drivability traits, and maintenance-relevant highlights.

• i-VTEC control: The 1.8L and 2.0L engines use Honda’s variable valve timing and lift for a balance of efficiency and high-rpm breathing; the 2.0L Si’s DOHC setup is tuned for performance and revs to an 8,000 rpm redline.
• Timing chains: The gasoline engines (R18A1, K20Z3, and LDA hybrid unit) use timing chains rather than belts, reducing routine replacement intervals.
• Fuel and economy: The 1.8L runs on regular 87-octane gasoline; the Si’s 2.0L typically recommends premium for best performance. Hybrids leverage electric assist for improved city efficiency, while the GX’s CNG fuel dramatically cuts tailpipe emissions.
• Emissions tech: The Hybrid employs a battery-assisted system (IMA) to augment the 1.3L engine; the GX is engineered for very clean combustion on natural gas compared with conventional gasoline.

Together, these elements explain why the 2010 Civic range spans from ultra-efficient to enthusiast-oriented without changing platforms.

How to Identify Which Engine Your 2010 Civic Has

If you’re unsure which powertrain is in a specific car, these practical checks can help you confirm the engine quickly and reliably.

1. Trim indicators: Look for badging—“Si,” “Hybrid,” or “Natural Gas/GX.” Non-Si, non-Hybrid, non-GX models are typically the 1.8L.
2. Tachometer cues: Si models have an 8,000 rpm redline; other gasoline models are lower. Hybrids include battery state-of-charge/assist gauges.
3. Under-hood label: The emissions label on the underside of the hood lists the engine family/code (e.g., R18A, K20Z, LDA) and fuel type.
4. Transmission and controls: Si uses a 6-speed manual only; Hybrid has a CVT shifter pattern; most 1.8L cars offer 5-speed manual or automatic; GX models were automatic-only and have CNG-specific fueling hardware.
5. Documentation: The owner’s manual, original window sticker, or a VIN-based build sheet from a dealer can confirm exact specs.

Using two or more of these checks usually provides definitive identification without specialized tools.

Global Variations to Know

Outside North America, the 2010 Civic’s engine mix differs. The European lineup centered on 1.4- and 1.8-liter i-VTEC petrol engines and a 2.2-liter i-DTEC diesel, while performance variants like the Civic Type R used a high-revving 2.0-liter. In Japan, 1.8- and 2.0-liter petrol options were common, including a Type R sedan (K20A) in certain years. Always verify regional specifications when shopping or sourcing parts internationally.

Summary

In 2010, most Honda Civics in North America used a 1.8-liter SOHC i-VTEC four-cylinder, the Si stepped up to a 2.0-liter DOHC i-VTEC performance engine, the Hybrid combined a 1.3-liter gasoline unit with an electric motor, and the GX ran a CNG-tuned 1.8-liter. Trim and market determine the exact engine, so check badges, the under-hood label, and documentation to be sure.

Is a 1.5 or 2.0 engine better?

1.5 Turbo vs.
This engine is ideal for those who prioritize fuel economy and everyday usability. In contrast, the 2.0L turbo engine delivers a robust 252 horsepower and 260 lb-ft of torque, providing a more exhilarating driving experience with greater towing capabilities.

Does the 2010 Civic have VTEC?

The Civic Si Sedan and Coupe serve as the performance cornerstone for the Civic lineup with a 197-horsepower, 16-valve, DOHC, 2.0 liter i-VTEC 4-cylinder engine mated to a close-ratio, 6-speed manual transmission.

Is the 1.7 L Honda motor a VTEC?

In May 2004, alongside the introduction of a 2.0L i-VTEC variant, a 1.7-liter VTEC variant unofficially replaced the 1.7-liter VTi-S variant.
