Civic Si in Greater Westford

  • Daily drive: Short gearing and early torque make Route 27 gaps easier; rev-match helps on rolling two-lanes toward Carlisle
  • Winter note: The Si is FWD; pair with dedicated snow tires for the steeper bits near Nabnasset. Keep rev-match on for smoother, controlled downshifts on slick days.¹
  • Weekend play: Easy hop to Devens for autocross or a spirited loop across the Acton–Concord backroads—then back in time for coffee on Littleton Rd.
2025 Honda Civic Si - Power and Performance

2026 Honda Civic Si Power and Performance

The Si’s 1.5-liter turbo is tuned for real-world punch, with torque plateauing early for quick response out of tight bends on Powers Road and Graniteville Rd. A single-mass flywheel sharpens rev response, and the rev-matching 6-speed makes smooth downshifts second nature. The helical LSD helps the Si put power down cleanly as you unwind the wheel.¹

  • Output: 200 hp / 192 lb-ft, redline 6,600 rpm
  • EPA: 27/37/31 mpg—impressive for a manual sport compact.²
  • Steering & brakes: ~11.46:1 steering ratio (≈2.17 turns L-L); 12.3-in vented fronts / 11.1-in rears

Dimensions & key specs

  • Wheelbase: 107.7 in • L/W/H: 184.0 / 70.9 / 55.5 in • Curb weight: 2,952 lbFuel tank: 12.4 gal

Track/AX tip: For local SCCA at Devens (Moore Army Airfield), a set of 200-treadwear summer tires in the stock 235/40R18 size sharpens turn-in and braking. (Honda does not list a factory summer-tire package for 2026; choose aftermarket rubber seasonally.)⁴⁸
