The 2015 Honda Civic LX is powered by a 1.8-liter inline-4 engine with Honda’s i‑VTEC technology, delivering about 143 horsepower and 129 lb-ft of torque.
Overview of the US-market engine
In the United States, the ninth-generation Civic (2012–2015) used the 1.8L i‑VTEC engine across LX, EX, and EX-L trims. Here are the core specifications you’ll typically find on a 2015 LX:

Additional context
For comparison, the Civic Si variant used a different engine (a higher-output 2.4-liter inline-4), while later generations introduced turbocharged or larger-displacement options. The 2015 Civic LX centers on the 1.8L i‑VTEC engine as its standard powerplant.
Summary
The 2015 Honda Civic LX uses a 1.8-liter inline-4 i‑VTEC engine (R18A), producing about 143 horsepower and 129 lb-ft of torque, with either a 5-speed manual or CVT automatic transmission depending on the configuration.
