Is my high wh/mi normal for my P84+?

[Djsmooth56]

So I just got back from a trip primarily on back roads around Michigan and thought I would see some pretty good wh/Miles average, but ended up averaging about 350! Here are my specs, I’m hoping some of you experts out there can tell me if this is normal or an indication of something wrong I need to address.

2014 MS P85+
Adaptive air suspension
About 110k on the odometer
Staggered 20” MX slipstreams
Recent drive about 400 miles
Minimal winds, about 75* average temp
Cruise set at 60 mph with minimal stops
Overall average of about 350 wh/mi
Only able to get about 140 miles from a full charge in this condition.

Any help is appreciated

The wheels aren’t doing you any favors

Check tire pressures. I would over inflate slightly. Most likely this is a result of the wheels.

My experience on backroads are they are not best for Wh/Mile average, too many curves and I tended to slow down into and accelerate out. Don't read too much into one trip, too many factors can distort. What is you lifetime Wh/mile, My '14 P85 averaged 305.
