Not in horsepower. In power per tonne — the one number that puts a Polo and a Panamera on the same scale. Type a Dutch plate and see where the car stands against every combustion car in the country.
The plate goes straight from your browser to the RDW's open data. Hoscorp never sees it and never stores it.
Out of every hundred Dutch cars with an engine, — have less power per tonne than this one.
Computed with the same physics model Corso uses, from power, mass and body shape. A prediction, not a measurement.
Half the fleet sits below this. An average Dutch car takes something like ten seconds to reach 100.
Distribution of power per tonne across the Dutch fleet.
This car cannot be compared fairly, and that is not the car's fault.
For an electric car the register records only continuous power: the output the motor can sustain indefinitely. Not what it delivers when you flatten the pedal. That second number — peak power, the figure the car actually accelerates on — is recorded nowhere.
A petrol car does have a peak figure on file. So the two cannot be laid side by side, and you get no percentile and no estimated 0–100 here. A number we made up would be worse than no number.
This car cannot be compared fairly, and that is not the car's fault.
A hybrid has two power sources. The register lists the output of the combustion engine, and separately at most the continuous output of the electric motor — but nowhere what the car delivers as a whole. Nor can you simply add them up: they do not peak at the same moment.
Take the petrol engine alone and a Toyota Prius lands in the 1st percentile at over seventeen seconds to 100, where the real answer is closer to eleven. That result is not cautious, it is wrong. Hence no number.
Continuous power. — per tonne, if you used this figure — which everyone pulling this data does.
Unknown, to everybody. The peak output of this vehicle is not a publicly registered fact.
Dutch cars sit in the same category, and every comparison site using this open data gives all of them the same wrong figure.
Together that is over two million cars — close to one in five on the road — whose power the official register does not describe. Every site, every comparison tool and every insurer pulling power from this data pulls the wrong number for them. Including us. The difference is that we say so.
Asking the server…
Everything above comes from a paper car: power, mass, an assumed drag area. It knows nothing about your tyres, your gearbox, your launch, or your day. On average it lands within about 8% — on an eight-second car that is more than half a second either way.
Corso measures the same 0–100 with the phone already sitting in your car, and publishes the uncertainty it was measured to. A time of ±0.05 s is gold. Most attempts do not get there, and that is the point.
