Well, I now know mine is faster stock for stock because I was ahead by 2 to 3 car lengths to 80 MPH. No other traffic was around and we had 3 lanes of open road for about a mile. I didn't think it would be that much of a difference but I just kept pulling on him so I shut it down at 80. No reason to keep going!!! He had a tough time looking at me at the next light, but that's the way it goes. My car may not be able to handle as well as the 2015, but it sure is nice to be a little quicker.
