2017 Honda Civis Si Has Finally Arrived

For the first time in Civic Si history, an advanced turbocharged engine powers the Civic Si Coupe and Si Sedan. An enhanced version of the 1.5-liter 16-valve DOHC direct-injected turbocharged powerplant that powers EX-T, EX-L and Touring Civics, the new Si engine pushes performance on multiple fronts. It's rated at 205 hp at 5700 rpm and offers an impressive 192 lb-ft. of torque between 2100 and 5000 rpm. That's an increase of 31 hp and 25 lb.-ft. of torque, as compared to other 1.5-liter turbocharged Civic models.

The new Si also marks a bold shift in strategy when compared to the previous generation 2015 Civic Si. With a displacement reduction of 36-percent compared with the normally aspirated 2.4-liter engine that powered the previous Si, the new 1.5-liter engine is lighter, more compact and more efficient. With the help of a sophisticated, electronically controlled, intercooled turbocharging system, the new Si offers the same peak 205 horsepower as its predecessor, but at a lower, much more quickly accessible rpm. More important, the new turbo engine offers a decisive peak torque advantage over a far broader rpm range. The result is a highly responsive powertrain that advances the Si's fun-to-drive mission.

Of course, some things have not changed in the new Si. It is still offered exclusively with a 6-speed manual transmission for the maximum in driver control and tactile connection, though the all-new gearbox offers a slicker shift action-and revised ratios to suit the power delivery of the new turbocharged engine. And to help put power to the ground, as in the past, a helical limited-slip front differential is standard.

The Civic Si engine is EPA Tier3/Bin125 and CARB LEV 3/ULEV125 emissions compliant. The new, more efficient engine and transmission, along with improved aerodynamics and a major reduction in running resistance, result in substantially enhanced performance and fuel efficiency, compared to the previous generation (2015) Civic Si 2.4-liter.
