2026 Honda Civic Si vs 2027 Kia K4: price, specs and what it costs in Frisco
Base trims, published figures from each brand’s own spec sheets. I show the starting price of both cars and the rows where the Civic Si comes out ahead; the K4 wins rows of its own, and its full sheet is on Kia’s site. What I can add that a spec sheet can’t is what the Civic Si actually costs on our lot today.

| Starting MSRP | $31,495 | $22,390 |
| Horsepower | 200 hp | 147 hp |
| Torque | 192 lb-ft | 132 lb-ft |
MSRP excludes destination. Figures are each brand’s published base-trim numbers at the time of the last competitor refresh and can change with a model year.

What I’d do before choosing
Drive both, back to back, on the roads you actually use. Numbers settle the budget; the seat, the sightlines and the way it pulls away from a light settle the rest. If the K4 turns out to be the better fit for you, I’ll say so. I’d rather you buy the right car.
