In the U.S. market, the 1990 Civic sedan typically produced about 92 horsepower from the standard 1.5-liter engine.
Across other markets, Honda offered a 1.6-liter option with roughly 105–110 horsepower, and there were high-performance variants in select regions that delivered substantially more power. The exact figure depends on market, trim, and emissions specifications, making the 1990 Civic sedan a range rather than a single fixed number.
Engine options by market
The following summarizes the main engine configurations and their horsepower figures associated with the 1990 Civic sedan, noting that availability varied by country and trim.
US-market 1.5L engine
In the United States, the 1990 Civic sedan primarily used a 1.5-liter engine in base trims, delivering modest horsepower suitable for daily driving.
- 1.5-liter four-cylinder (D-series): about 92 hp
That 92-horsepower figure corresponds to the commonly-equipped US 1990 Civic sedan baseline.
Non-U.S. markets — 1.6L option
In many overseas markets, Honda offered a 1.6-liter engine that produced more horsepower.
- 1.6-liter four-cylinder (D16A family): around 105–110 hp
This displacement increase yielded roughly 10–18 hp more than the 1.5L option, depending on market and emission standards.
High-performance variants (VTEC) in select markets
In certain regions, notably Japan and other specialized markets, the Civic offered a 1.6-liter DOHC VTEC engine for higher performance.
- 1.6-liter DOHC VTEC (B16A): approximately 150–160 hp, depending on spec
These higher-power variants represented the horsepower peak for 1990-era Civics but were not typical for the U.S. sedan lineup in 1990.
Summary
The 1990 Honda Civic sedan’s horsepower varied by engine and market: around 92 hp for the common U.S. 1.5L base, about 105–110 hp for the 1.6L option in other markets, and up to roughly 150–160 hp in VTEC-equipped variants found in select regions. For most U.S. owners, the baseline figure of about 92 hp is the relevant benchmark, while international versions offered modest and substantial upgrades depending on the configuration.
