2012 C250 has a higher gear ratio than 300 - to make sure it's same or slower as 300 after the 250 shed 400 lb and got the same power LOL.

I am guessing they just changed the diff gear because it is simplest
and cheapest - just makes sense.

Anyone know for sure if the 250's software will notice if it has the 300 differential gearing?
