Engine and Transmission Rating:
There’s only one available powertrain for the Civic Si, and it’s very good-although its small turbo engine does suffer from boost lag when the revs are low. The six-speed manual is a joy to row.
What’s New for 2018?
While the Si would benefit from the extra pep that comes with increased power, its current price and performance slot nicely between the 180-hp Civic Sport and the 306-hp Civic Type R. That said, we don’t mind that Honda has not altered the Si’s powertrain for 2018.
2017 Honda Civic Si
The Si is powered by a 205-hp turbocharged 1.5-liter inline-four that sends its power to a six-speed manual gearbox and then on to the front wheels. The engine makes its 192 lb-ft of torque fairly low in the rpm range, but you’ll still want to keep the revs above 3000 to feel the engine in its full glory.
Once you’ve found the torque, zipping around in the Si is a gas. The car is light enough that you’ll rarely want more power-it sprints to 60 mph in 6.3 seconds-even though some of its competitors offer significantly more horsepower. And once you’ve mastered the springy clutch, the transmission and the engine play well together.
