4 CYL Designation

baabootoo · Mar 20, 2021

On my 2019 Scat Pack, when in the mileage screen, 3 down clicks from the speed, it showed Average MPG, Instant MPG, and a circular gauge. In the middle of the circle, it would show "4 CYL" when it was in it; in STREET Mode or ECO Mode. My 2015 Hellcat never shows it, no matter what. I'm not sure 100% it's in 4 CYL mode, but will check in a couple of days. Did all models show this then? Thanks.

No MDS, or 4 cycle mode, on Hellcats; luckily.

6.4l has MDS. 6.2l Hellcat engine does not.

Yes as stated above, the 5.7 & 6.4 hemi engines both have MDS/4 Cylinder mode. Only available with the 8 speed auto. The 6 speed manual cars do not have the cylinder deactivation

Damn, ok, thanks people.

Run in Sport mode and no more MDS. [emoji106]

No, I WANTED MDS. I'm abnormal..............

I didn't mind it either as there is a way around it when you don't want it. But on the highway, it is worth a solid 4 mpg.

Exactly! I was worried someone had tuned it out since it was used.
