  • Hint: Use a descriptive title for your new message
    If you're looking for help and want to draw people in who can assist you, use a descriptive subject title when posting your message. In other words, "I need help with my car" could be about anything and can easily be overlooked by people who can help. However, "I need help with my transmission" will draw interest from people who can help with a transmission specific issue. Be as descriptive as you can. Please also post in the appropriate forum. The "Lounge" is for introducing yourself. If you need help with your G70, please post in the G70 section - and so on... This message can be closed by clicking the X in the top right corner.

I recently took a road trip in the "New to me" 2021 G80 Prestige V6 RWD. I was pleasantly surprised with 31 mpg. I was wondering if this is good or average? I know the around town MPG is about 20 MPG. And short trips in town I'm lucky to get 16 MPG.

Can't speak exact apples to apples, but I get about 26mpg highway on my 3.5 GV80 which is AWD and a good bit heavier.
Your G80 mpg seems normal to good range within that framework.
I have noticed for me, the shorter the trip, the worse the mileage--It takes at least 4-5 miles of non-stop and go (speed independent) to get up to par mpg, but then it performs as advertised.
Overall, in 65% ex-urban/ 35% highway I have gotten about 21mpg ave over the past 3000 miles, and a small part of that is hill/mountain driving.

Sounds similar to what I'd get over time. Short trips in cold weather hits it hard. On the way to a store 2 miles from my house it would be 12 mpg, on the return trip with the engine a bit warmer would be 14 mpg. If I got on the highway, it would jump to double that.

Yea....the short trips around town running errands the mileage is pretty poor. But when Genesis stated 27 mpg for highway and I got 31 I was more than happy.
