BMW 7 Series Plug-in hybrid
The window sticker shows one number. This car has three — 24 MPG with a flat battery, 70 MPGe on electricity, and a blend of the two that assumes you drive 64% of your miles on the battery. Which one applies to you is decided by how often you plug in, not by the EPA.

How this is worked out
Your electric share is your daily electric miles over your daily miles, capped
at the 35-mile rated range per charge. That share is costed at the electricity
price and the rest at the gasoline price. The kWh figure is EPA's combE, measured
at the wall, so charging losses are already inside it — you are not paying for
them twice.
Every figure comes from the U.S. EPA's public fuel economy data. We add no estimates of our own; a missing number shows as a dash rather than a guess.

Federal data has at most a handful of owners per car and nothing at all on servicing. If you own one, send what you actually get. It goes on this page with the sample size next to it.
