What engine is in a 2007 Honda Civic?

Most 2007 Honda Civics are powered by a 1.8-liter i-VTEC inline-four (engine code R18A1). However, the exact engine depends on trim and market: the performance-focused Si uses a 2.0-liter DOHC i-VTEC (K20Z3), the Hybrid pairs a 1.3-liter i-VTEC (LDA) with Honda’s Integrated Motor Assist (IMA), and select models include a factory CNG version (GX) based on the 1.8-liter. Outside North America, additional 1.4-, 1.6-, 1.8-, 2.0-, and 2.2-liter options were offered.

Engines by market and trim (2007 model year)

North America (U.S./Canada)

In the U.S. and Canada, the eighth-generation Civic lineup offered distinct powertrains across trims, from economy-focused models to performance and alternative-fuel variants.

• DX, LX, EX (and most mainstream trims): 1.8L i-VTEC inline-4 (R18A1), approximately 140 hp.
• Si (coupe/sedan): 2.0L DOHC i-VTEC inline-4 (K20Z3), approximately 197 hp.
• Hybrid: 1.3L i-VTEC inline-4 (LDA) with IMA electric motor, combined output approximately 110 hp (CVT only).
• GX (Natural Gas): 1.8L i-VTEC inline-4 tuned for CNG (R18-based), approximately 113 hp.

These engines prioritized efficiency and reliability, with the R18A1 serving as the volume model, the K20Z3 delivering high-rev performance for the Si, and the Hybrid/GX offering lower emissions and fuel-cost advantages.

Europe and other regions

Engine offerings varied more widely outside North America, reflecting local emissions rules, fuel preferences, and performance variants.

• 1.4L i-DSI inline-4 (L13A): roughly 83–90 hp (market-dependent), focused on economy.
• 1.8L i-VTEC inline-4 (R18A2): about 138 hp, the common mainstream European choice.
• 2.2L i-CTDi diesel (N22A2): about 138–140 hp, strong torque for efficiency and motorway use.
• Type R (FN2): 2.0L DOHC i-VTEC (K20Z4), roughly 197–201 hp depending on rating standard.

Outputs in these regions may be quoted in PS or kW, so published figures can differ slightly from U.S. hp ratings, though real-world performance is comparable within each trim class.

How to confirm which engine your Civic has

If you’re unsure which engine is in your specific 2007 Civic, several identifiers on the car and its documentation can verify it quickly.

1. Under-hood emissions label: Typically on the underside of the hood or near the radiator support; often cites engine family/code.
2. Engine code stamping: Look on the engine block (front/side), where the alphanumeric code (e.g., R18A1, K20Z3) is stamped.
3. VIN decoding: A dealer or reputable VIN decoder can map your 17-digit VIN to the exact engine/trim.
4. Owner’s manual/build sheet: Trim and powertrain details are usually listed.
5. Dealer service department: Provide your VIN for an authoritative lookup of the engine and original equipment.

These methods ensure you identify the precise engine and avoid confusion across trims and markets.

Key specs at a glance

Here are the headline figures most shoppers and owners reference for U.S.-spec 2007 Civics.

• 1.8L R18A1 (DX/LX/EX): ~140 hp; SOHC i-VTEC; gasoline.
• 2.0L K20Z3 (Si): ~197 hp; DOHC i-VTEC; high-revving performance tuning.
• 1.3L LDA + IMA (Hybrid): ~110 hp combined; gasoline-electric hybrid with CVT.
• 1.8L R18-based (GX): ~113 hp; factory Compressed Natural Gas (CNG) application.

Exact horsepower and torque can vary slightly by testing standard and market, but these figures reflect widely cited factory ratings for the 2007 model year.

Summary

The 2007 Honda Civic most commonly uses the 1.8-liter i-VTEC (R18A1) inline-four, while the Si features the 2.0-liter K20Z3, the Hybrid pairs a 1.3-liter LDA with IMA, and the GX runs a CNG-tuned 1.8. Outside North America, additional 1.4-, 1.8-, 2.2-diesel, and Type R 2.0-liter options were available. Check your under-hood label, engine stamping, or VIN to confirm your specific engine.
