The complete sound of the car: http://www.roadandtrack.com/new-cars/news/a26065/koenigsegg-regera-sound/
The car doesn't really make 1800HP due to the fact that the third electric motor doesn't supply power, because if it were to do so, it would've been all-wheel drive and it could've increased the weight. All the electric motors are spread out, with the two on the rear delivering the power along with the 5.0L twin turbo V8 engine, making it a some sort of MR car.
Well, from that tweet that there were guys from Sony using microphones to record the car's engine seems promising, but it's more likely than not going to land into Driveclub, because it is obviously more supercar-centric.
Since this car goes into production this year, shouldn't the title be 2016 and not 2015? If it's 2015, it needs to have a car show attached to the title, like Geneva Motor Show....
Drove this in Driveclub last night (through the Downforce events), it's really fast like it's not a car at all, it's a spaceship with a twin-turbo hybrid V8 and with wheels.
Just a little heads-up, if the Regera were to feature in GT Sport, chances are it will be in Gr. X (for concepts, Vision cars, electric vehicles, safety cars, non-street legal track-day cars and other such road/racing cars that do not belong into any other category). This is due to its direct drive system and the lack of a gearbox, thus making the car behave like an electric vehicle.
