2025 Honda Civic Hatchback Sport

K20

2.0L Naturally Aspirated I4

The naturally aspirated K20 in the Civic is smooth, eager and happy to rev, delivering its power linearly without turbo lag in a way that defines Honda's reputation for sweet four-cylinders.

Part of Honda's celebrated K-series, which debuted in the early 2000s and became a tuner and motorsport legend; the Civic's port-injected variant (K20C2) is built on the same family that spawned the turbocharged Type R engine.

• It uses Honda's i-VTEC, which continuously varies intake cam timing across the whole rev range rather than just switching at high rpm.
• The base Civic's unit shares its K20C engine family and 86mm bore with the Civic Type R's turbo motor, but stays naturally aspirated and port-injected.
• It is among the last port-injection-only engines Honda will build before moving on.
