The 49-year-old took his rides for a spin on former business partner and fellow Russian oligarch Viktor Kharitonin’s world-famous track.
Kharitonin closed the track for two days in order for the billionaires to play with their toys.
Abramovich also brought a Ferrari FXX, a Bugatti Veyron, a Ferrari 488 GT3, a Mercedes-Benz AMG GT3, a Lamborghini Reventon and an Aston Martin Vulcan.
A Nurburgring instructor, Tatiana Golovlyovo, said: “Usually track days are organised for the owner of the Nurburgring, Viktor Kharitonin. This is an exclusive event for the owner and his friends, nobody else (apart from the staff and crew working for event) can enter the property.”
Reports suggest the businessmen spent the first day racing on the ‘Nordschleife’ (‘Northern Loop’), which covers 13 miles.
The second day involved the shorter GP Strecke, which spans 3.2 miles.
The Russian moguls also tested the entire range of the Porsche sports cars and the single-seated “Formula-BMW” vehicles throughout the event.
