The 2007 Honda Civic Coupe offers two primary power levels depending on trim: about 140 horsepower for the standard 1.8-liter engine, and about 197 horsepower for the sport-focused Si model.
In 2007, Honda’s Civic Coupe was part of the eighth generation (2006–2011). The standard trims (DX, LX, EX) used a 1.8-liter i-VTEC engine rated at around 140 hp, while the high-performance Si trim used a 2.0-liter i-VTEC engine rated at about 197 hp. Transmission choices varied by trim, with the Si featuring a 6-speed manual and the standard trims offering either a 5-speed manual or a 4-speed automatic. In short, horsepower depends on the engine and trim rather than body style alone.
Power by trim
Before listing the horsepower figures, note that the two main engine options in the 2007 Civic Coupe drive the published horsepower numbers for each trim.
- 1.8-liter four-cylinder (DX/LX/EX): 140 horsepower
- 2.0-liter four-cylinder (Si): 197 horsepower
The standard trims deliver their power through either a manual or automatic transmission, while the Si is equipped with a 6-speed manual gearbox, which helps translate the engine’s 197 horsepower to road performance.
Transmission options by trim
Before detailing how the transmissions relate to the horsepower figures, it’s helpful to know the available gearboxes for each trim.
- DX/LX/EX: 5-speed manual or 4-speed automatic
- Si: 6-speed manual (exclusive to this trim)
In practice, the horsepower numbers come from the engine specification, while the transmission affects acceleration feel and gearing, not the official horsepower rating itself.
Why the numbers vary
The two power levels reflect Honda’s use of two different engines within the same model line. The 1.8-liter engine was designed for efficiency and everyday driving, producing 140 hp. The 2.0-liter Si engine was tuned for higher performance, yielding 197 hp and a more aggressive torque curve. This split is common across late-model Civics, where sportier variants offer a significant boost in horsepower over the base trims.
Summary
For the 2007 Honda Civic Coupe, expect about 140 horsepower in the DX/LX/EX trims with the 1.8-liter engine, or about 197 horsepower in the Si with the 2.0-liter engine. Transmission options vary by trim, but the horsepower figures are determined by the engine choice. The coupe body style itself does not change these numbers—the trim and engine do.
