Turbocharged 1.5-liter Engine

What’s the Benefit?
This engine delivers exhilarating acceleration while operating with excellent efficiency.

The Feature:
The current-generation Civic line received the first turbocharged engine powering Honda-badged automobiles in the U.S. market.

  • In addition to the intercooled turbo, this EarthDreams® Technology powerplant features direct injection, Variable Timing Control (VTC) on both camshafts and a dual-exhaust system.
  • Instead of employing VTEC® to spread torque throughout the rpm range, it uses the torque-expanding benefits of turbocharging. 
  • Thanks to careful tuning and use of a relatively small-diameter turbine wheel, Honda’s version of the forced-induction engine exhibits negligible turbo lag—a phenomenon that bedevils many of its turbocharged competitors—so response to the throttle is quick.
  • As configured for the Si, this engine uses different pistons, valves and turbocharger tuning to increase peak power production to 205 hp and 192 lb-ft of torque.
  • Plus, that torque peak starts low and stays strong a long time as the revs rise, for a sustained blast of acceleration.
  • Perhaps most remarkable of all, this engine can provide all that exhilaration while receiving excellent EPA fuel-economy ratings.36
