Recently took a road trip to Pittsburgh from Philadelphia. And then on the way home got a new all time best! 58.2 max wooo! I've largely got the mountains to thank for this as before this long essentially straight downhill trip. My previous best was 49.8 I believe. I was holding out to crack that magic 50 number but just didn't drive anywhere that gave me the opportunity.
This is purely due to circumstance though for anyone still doubting this. I kinda knew this was always the case when people would post crazy numbers but it's still fun to hit it yourself Typically highway mileage in my car on relatively flat ground is around 40mpg, and city driving is between 25-30. So not complaining at all, that's great mileage and one of the main reasons I got this car but when people post these images I just want to be clear, that's cuz they live near a hill
