The 2007 Honda Civic EX uses a 1.8-liter inline-4 i-VTEC engine (code R18A1), a DOHC design delivering about 140 horsepower and 128 lb-ft of torque, paired with either a 5-speed manual or 5-speed automatic transmission.
In the seventh-generation Civic (2006–2011), the EX trim prioritized a balance of efficiency and everyday performance. This engine is front-wheel drive and should not be confused with the higher-performance Civic Si, which uses a different 2.0-liter powerplant.
