Vehicle Profile
Profiles are public-knowledge approximations, not manufacturer-certified figures.
Entering your car's own reading gradually corrects the estimate above toward reality — it doesn't replace it.
About the numbers. Eco Efficiency, Power & Regen, and Trip stats are estimates calculated on this device from GPS speed and a generic physics model — not a reading from your car. All data stays on this device only.
