but since the benefits of upgrading the pre AP cars are microscopic I will delay the upgrade anyway. .. If they fix the Nav and DAB-radio I will reconsider...
there's a thread on improved wh/mi in rwd cars on 7.0. Appears to be ~10%. I'm experiencing. Assumption is it's related to torque sleep. That's not microscopic! If they find another 10% in 7.1, they can move the battery gauge wherever they want IMO.
