Honda Civic trim comparison
2026 Honda Civic Sport vs Si
The Civic Sport starts at $26,695 while the Si is $31,495. That $4,800 gap buys 6 meaningful differences.
This trim jump changes the engine from 2.0L I4 to 1.5L I4 Turbo. Everything else is secondary to whether that powertrain difference matters for how you drive.
If you would notice the 1.5L I4 Turbo every week, the Si makes sense. If not, the Sport is the cleaner stop because this jump matters for the powertrain first and the trim badge second.
Think about this as a monthly tradeoff, not just a sticker gap. The Si adds about $85/month on a typical 60-month loan, or around $5,100 more overall with interest. If that different powertrain is not part of your real use case, the cheaper trim keeps more money in your pocket without changing the core experience you need.
Lock one trim, change the other side, and move through exact pair pages without resetting back to the full lineup every time.
