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.
Drivers will appreciate impressive power output: 174 horsepower in most trims.
Torque production is admirable as well, at 162 lb-ft for most models.
Plus, that torque peak starts low and stays strong a long time as the revs rise, for a sustained blast of acceleration.
As configured for the Si Coupe, this engine uses different pistons, valves and turbocharger tuning to increase peak power production to 205 hp and 192 lb-ft of torque.
Perhaps most remarkable of all, this engine can provide all that exhilaration while receiving excellent EPA fuel-economy ratings.36
