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