Smarter vehicle comparison
Combined WLTP values don't reflect how you actually drive. Premium gives you a personalized cost analysis that matches your real-world driving.

Why combined WLTP values are misleading
The official "combined" consumption figure is a fixed-weight average of different driving conditions. It assumes every driver spends the same proportion of time in city traffic, suburban roads, country roads, and on the motorway. In reality, your driving pattern is unique.
A driver who commutes mostly on the motorway will see significantly higher fuel consumption than the combined figure suggests, while a city-only driver might do better. The difference can easily be 20-30% in real-world costs.
How premium calculations work
Weighted consumption by driving profile
Instead of using the combined figure, we weight each road type's consumption (city, suburban, country, motorway) by the percentage you actually drive on each. If you drive 60% motorway and 40% city, your weighted consumption reflects exactly that mix - giving you a much more accurate annual cost estimate.
PHEV electric share from daily commute
For plug-in hybrids, the official WLTP consumption assumes a specific charge-depleting ratio that rarely matches reality. We estimate your actual electric driving share based on your daily commute distance and the vehicle's electric range. A 50 km electric range with a 30 km daily commute means most of your commuting is on electricity - and that massively changes the cost picture compared to the WLTP combined figure.
Home vs. commercial charging costs
Electricity price varies dramatically depending on where you charge. Home charging at ~€0.30/kWh vs. commercial fast charging at ~€0.55/kWh can double your per-kilometer cost for EVs and PHEVs. Set your home/commercial charging split and get an accurate blended electricity price.
Depreciation & total cost of ownership
Fuel costs are only part of the picture. Premium includes estimated value depreciation over your ownership period, giving you the true total cost of ownership (TCO). This lets you compare whether a cheaper car with higher running costs actually costs more than a pricier, more efficient one over 3-5 years.
