[VIDEO] See a Koenigsegg One:1 rumble its engine in the showroom image

A Koenigsegg One:1 is the star of a brand new video which is showing the “megacar” rumble its engine inside a showroom.

The fastest road-legal production supercar of our times is the Koenigsegg One:1 and considering the fact that this is one highly exclusive and very expensive vehicle, almost every appearance is making cameras, or alarms in this case, go wild. The clip posted below is showing such a “megacar” rumble its engine inside a showroom which made a Ferrari 599 GTB start its alarm.

As you probably remember, the Koenigsegg One:1 has been officially presented to the public, in its current form, back in March this year, during the 2014 Geneva Motor Show. The supercar in question is the fastest ever production model and it is said to have a top speed of 450 km/h. This is possible thanks to the 5.0 liter V8 aluminum engine which is found under its hood, as this is producing a total output of 1,341 HP (986 kW) and 1,371 Nm (1,011 lb-ft) of torque, available from 6,000 rpm. The One:1 name is coming from its power to weight ratio as this is weighing 1,341 kg.
