My friend's new S75 gets 257 miles at 90%???

[aus]

My buddy just picked up a S75 about 2 weeks ago, and he was showing me on the Tesla App he gets around 25x miles range at 90%. I was pretty shocked since my S85 (Nov 2015 with around11,800 miles) gets around 240 miles at 90% charge.

Is this pretty typical? I wouldn't have believed it if I didn't see it on his phone. Now I want to trade "up" and possibly lower my monthly payment if Tesla wants my car back.

They must have put the wrong battery in at the factory!

Your friend has the system set on ideal miles instead of rated miles.

He has his set to "Ideal" miles instead of "rated".

He has his set to "Ideal" miles instead of "rated".

Or your friend is driving at 45 miles per hour or downhill most of the time.

I didn't even know there was an "Ideal Miles" setting.
I'm assuming it's under some setting in the center panel?
