I think your 2018 CTR and your 2016 SS calculations are off, if your weight for the 2018 CTR is correct and hp is correct it should be
2018 CTR 3100 lbs 316HP = 9.81 lbs / HP
2016 SS 3650 lbs 455 HP = 8.02 lbs / HP
That's one nice looking Civic. I can't wait till we get them in at our local dealership!! G26, what were your impression of the LED lights? Do the lighting seem as good as HID's?
