I have a 2018 Civic LX coupe with a manual. And a 2020 Civic Sport sedan with a manual.
Plan to sell the 2020 to get a 2022 Civic Sport Hatchback with a manual.
All 3 have the same K20C2 - 2 liter engine, same HP and torque.
158hp/138lb-ft
Even the same gear ratios.
Weight:
2018 LX coupe: 2739 lbs
2020 Sport sedan: 2838 lbs (+99 lbs)
2022 Sport HB: 2932 lbs (+193 lbs)
Found this politically incorrect old MT article discussing weight reduction effect on performance.

"With calculations complete, final numbers show a horsepower to weight ratio of 18.18. For every 18.18 lb removed, the car will gain approximately one horsepower. The same properties apply for the torque figures as 1 lb-ft of torque is gained for every 22.04 lb removed from the vehicle. Keep in mind the calculations were made with a 165 lb driver on a bone-stock Civic. If your weight is on the heavier side, plug in your own numbers before dividing, Porky!"

So maybe a 10hp and 8lb-ft "loss" between the 18 coupe and the new hatchback.
Will probably switch to some lightweight Enkei TS-10s when I get the 2022.
Wish Honda had added a little more push to the base engine.
