No Tesla P100D? I was expecting that at or near the top.
Top 100 quickest launchers 2020
50 kph is speed at which very powerful cars have not had a chance to deliver all the power to the ground.
Below 50 kph it's all about traction. All wheel drive vehicles have clear advantage here, at least in theory.
Modern 2 wheel drive vehicles also benefit from electronic traction control and launch control which helps to keep wheel-spin under control.
Lighter vehicle with good traction is capable of quicker launches than some heavy, more powerful vehicles.
The 0 - 50 kph time is, perhaps, underrated as a measure of road car performance, because we more often sprint to 50 at the traffic lights, than we do 0 - 100 kph. If "real world performance" is your primary concern, you should consider the 0 - 50 kph times.
This list is limited by available data and new vehicles will be added as new data arrives.
