I was watching the RPM's on my scanguage and it got me to wondering, is there a red line for the ICE and/or does it have a governor to keep it from redlining since, in reality, there is no RPM gauge.
Between the transaxle setup and all the electronics governing it, I doubt there's any way in hell to over rev it.
Gen 1 4500 RPM Gen 2 5000 RPM Gen 3 5200 RPM (Includes PHV and v) I have no hard info on a c, sorry. It's power peak is at 4800, but I do not find a redline.
The car won't let you hurt the ICE. If you hit a good hill going 80mph with the cruise on, it'll rev to 5k RPM (on my Gen2) and hold it till the load decreases. It sounds the same as if you tried to hold it at 4900RPM, not cutting fuel or spark like if you hit the limiter in a manual transmission car. Floor it the next time you get on the freeway (safety first, of course). You'll hear it revving up and then stop and hold the max RPM.
Redline is not an issue. Your engine is governed by the computer. I've seen my 2012 C get to about 4884rpm.
Another situation where it will spin up to max RPM and hold is when you're going down a steep hill with the shifter in "B" ("brake" mode, usually known as "L" for "low" in other cars) with a completely full battery (all battery gauge bars lit). The car can no longer use regen as a braking force and so the engine RPMs go way up to compensate by using maximum compression braking.
These are "fly-by-wire". Your input to the gas pedal is simply a request. The car will accommodate the request as it sees fit.
Or as the avengers would put it, "I recognize you've made a decision to overrev the engine, but given that it's a, stupid nice person decision, I've elected to ignore it." SM-G892U ?
