When Ferrari took the wraps off its new FXX K track machine in Abu Dhabi last week, it conspicuously left out some key details. Sure, the Prancing Horse marque told us how much power it produced, and what it had done to the aero package to make it hug the track even closer than the road-going LaFerrari on which it's based – but it didn't tell us just how fast it will go, or how much it will cost. The latest reports, however, seek to fill in those blanks.

The FXX K will lap the company's Fiorano test track in 1 minute 14 seconds. That would make it five seconds faster than the LaFerrari, a solid second ahead of the 599XX Evoluzione and two seconds faster than the original FXX. However it seems to fall short of the eight- to nine-second gap those previous XX derivatives opened up over the road-going models on which they in turn were based.

So it seems, for the time being at least, that the 1:11.9 lap time recorded by the 333 SP – an open-cockpit sports prototype from the late 1990s – will remain for now the fastest car this side of an F1 racer ever to lap the circuit. The outright record stands at under 56 seconds and belongs to Michael Schumacher in the ten-cylinder F2004 he drove to his seventh and final world championship.

As for the FXX K's production, Ferrari will build fewer than 40 of them, and that they've all been spoken for – at a price of about S$4m a piece. If you're not one of those forty fortunate souls to have put down their deposit.
