Sky's compression ratio???? (12:1 vs 14:1)



the compression ratio in US website is 14:1.

the compression ratio in Canada website is 12:1.



which one is correct?????

[standsideways]

The skyactiv-g 2.0L is 13:1

The skyactiv engines that use the 4-2-1 header gets a bump to 14

The dirty diesel is 14:1

And just for shts and giggles the 2.3 DISI is about 9:1 iirc

Neither. You dont have the 4-2-1 exhaust.

Your car is 13:1

No. Without the header and on 87 octane gas compression is 12:1. Kimy27 we covered this in another thread.
