Opel Vectra

Fuel type as registered with the RDW. In the Netherlands this directly affects the recurring road tax (wegenbelasting): diesel and LPG are taxed considerably higher than petrol, and full-electric is currently the lowest.

Engine power in Dutch 'pk' (paardenkracht), equivalent to metric horsepower. 1 pk is about 0.735 kW, so the kW figure is roughly pk times 0.74.

One-time Dutch registration tax (BPM) charged on new cars, calculated from CO2. Already paid when the car was first registered in NL — this is not an amount you'd pay again, just context.

Quarterly Dutch road tax (motorrijtuigenbelasting / MRB) every owner pays, calculated from curb weight, fuel type, and province. Shown here as a monthly figure. Full-electric cars currently pay a reduced rate.

Dutch energy efficiency rating from A (most efficient) to G, derived from fuel use and CO2. Mainly relevant for newer cars and can affect lease/tax incentives.

Official CO2 emissions in grams per kilometre, as registered with the RDW. In the Netherlands this figure feeds into purchase tax (BPM) and some employer lease rules.

Curb weight (eigen massa) in kilograms as registered with the RDW. The Dutch recurring road tax (wegenbelasting / MRB) is calculated primarily from this weight plus fuel type.
