I have a 2011 Vehicle. Run the speed limit and do not shut off at red lights. No special hypermiling techniques other than keeping rpm down and not charging lights.
3 Stop Signs, 9 Traffic Lights and 10 Turns.
1 mile of 30 mph
0.5 mile of 40 mph
7 miles of 45 mph
1 mile of 55 mph
3 miles of 60 mph
3 miles of 70 mph
15.5 miles total from a cold start,
Average 25-28 mpg in 15F-80F conditions.
Yes there are many vehicles that could get 25-28mpg under those conditions. Since you are driving with FE in mind I'll assume you're getting a few mpg better than epa average, although there is plenty of variability in driving technique.
Candidates could be a compact pickup or suv, small or mid size sedan.
