In most configurations, a Honda Civic powered by a 1.8-liter engine produces around 140 horsepower. The exact figure depends on the model year and market.
Understanding the 1.8-liter Civic engine
The 1.8-liter Civic engines belong to Honda’s inline-four family and were tuned differently across generations and regions. While the labeling may vary (hp vs PS), the common output hovers around the 138–140 horsepower range, with torque typically around 128 lb-ft (174 Nm). Market-specific tuning and emissions requirements can create small variations in published numbers.
Before listing specific figures, note that multiple generations used a 1.8-liter setup, and exact horsepower can differ by country, model grade, and year. The breakdown below covers typical published values for widely sold Civic 1.8L configurations.
Typical horsepower by region and generation
Before the list, this paragraph explains that the bullets illustrate common published horsepower figures for 1.8L Civics across markets. Values may vary by year and emissions tuning.
- US-spec 1.8-liter Civic (often the R18A1 era, 8th/9th generation): about 140 hp (104 kW) at around 6,300 rpm; torque around 128 lb-ft (174 Nm) at about 4,600 rpm.
- European-spec 1.8 i-VTEC: typically listed as around 138–140 hp (roughly 102–104 kW), with some markets using 140 PS (approximately 138 hp) and torque near 173–174 Nm depending on variant.
- Other markets and model years: commonly fall in the same ballpark—roughly 138–140 hp—with minor differences due to fuel octane and specific tuning.
As newer Civic generations introduced smaller turbocharged engines or larger non-1.8 options, the availability of the 1.8L engine varied by market. If you’re looking for the exact figure for a specific car, share the year and country and I’ll pull the precise rating.
Bottom line
The standard 1.8-liter Civic typically delivers about 140 horsepower, with a torque figure around 128 lb-ft. Exact numbers can differ slightly by year, market, and emissions equipment.
Summary
For most 1.8-liter Honda Civics, horsepower sits around 140 hp (roughly 138–140 hp depending on labeling and market), with torque near 128 lb-ft. Check the exact engine code and regional specification for the precise figure for a given vehicle.
