First of all, hey guys im new to the forums

So last month i bought a cpo 08 g37 journey fully loaded and yesterday i heard squeaking when i backed out the driveway so i took it to the dealer to check it out. So they gave me a loaner vehicle which is a g37 sedan and dam...the sedan feels more responsive than my g37 coupe??? What could be the reason for this? It cant be the gas because i use 91 on my coupe. Any tips? (I'm a car noobie)

 

Probably the 5at vs. the 7at

 

I argee, I just traded in my 08 coupe with a 5 speed auto for a 2011 sedan with the 7 speed, it is quicker in the lower gears.

 

^ Most likely its the 7AT vs 5AT

 

Or 2008 vs 2011
