2023 Honda Civic Si Sedan Performance

The Civic Si uses a 1.5-liter turbocharged four-cylinder engine with 200 horsepower and 192 lb-ft of torque. It's exclusively paired with a manual transmission and front-wheel drive. Honda hasn't provided 0-60 times or a top speed figure but independent tests attained a 6.6-second sprint. All you need to know is that the Civic Si provides more than enough power for the daily commute, and merging with faster traffic on the highway isn't a chore. Too much power can corrupt the driving experience and the Civic Si's perfect balance of a sharp chassis and that torquey turbocharged engine work wonderfully.

Honda has tweaked the Civic Si's power plant for the new generation. The 1.5L four-cylinder engine remains turbocharged but now generates 200 hp and 192 lb-ft, the latter of which is on tap between 1,800-5,000 rpm, 300 rpm earlier than before. However, peak power has actually declined by 5 hp compared to the outgoing model. Honda says that throttle response has been improved by the implementation of a lighter, single-mass flywheel. In practice, we didn't notice the earlier-arriving torque but there's still pronounced rev-hang from the lightened flywheel. The rev-hang has no real impact on driving, but we imagine service departments are still going to have to explain to some customers that the engine not dropping its revs quickly when changing up is perfectly normal.

As standard, the Civic Si used a six-speed manual gearbox that now has 10 percent shorter throws. For the first time, the Si makes use of a rev-matching system, a piece of tech borrowed from the high-performance Civic Type R. Normal, Sport, and Individual driving modes allow drivers to customize the experience.

Gas mileage estimates for the new Honda Civic Si sedan are good. The sedan will achieve 27/37/31 mpg city/highway/combined. That's a little better than the VW Jetta GLI manual's 26/37/30 mpg.

The Honda has a 12.4-gallon gas tank so should be able to cover approximately 384 miles on a full tank.
