The 2010 Honda Civic’s 1.8-liter engine delivers 140 horsepower (SAE net).
For the 2010 model year, Honda’s 1.8 L inline-4 in US-spec Civics—covering LX, EX, and EX-L trims—produced 140 hp at 6,300 rpm and 128 lb-ft of torque at 4,300 rpm, with the powertrain choices typically including a 5-speed manual or 5-speed automatic transmission. The horsepower figure reflects SAE net ratings and is consistent with typical performance expectations for this generation.

Context and driving implications
Horsepower is a measure of an engine's raw output, but real-world performance also depends on gearing, weight, drivetrain, and aerodynamics. In the 2010 Civic, the 1.8 L engine is paired with either a 5-speed manual or a 5-speed automatic and delivers suitable daily drivability with reasonable acceleration for a compact sedan.
Historical context
During the 2010 model year, the Civic lineup emphasized efficiency and reliability, with the 1.8 L engine remaining the standard powerplant across most trims. The higher-horsepower performance variant for the Civic lineup is the Si, which used a more powerful 2.0 L engine, but that engine is not the 1.8 L discussed here.
Summary
In summary, the 2010 Honda Civic's 1.8 L engine delivers 140 horsepower (SAE net) at 6,300 rpm with 128 lb-ft of torque at 4,300 rpm, providing balanced performance for daily driving across LX, EX, and EX-L trims.
