The 2012 ADAC Zurich 24 Hours of Nürburgring was the 40th running of the 24 Hours of Nürburgring. It took place over May 19–20, 2012.
For 2012: The race was limited to a maximum of 190 cars/entries (down from a limit of 250 entries in 2011[1]), which started in 3 groups of up to 70 cars (maximum). Each entry must have between 2 drivers (minimum) and 4 drivers (maximum). Drivers may drive more than one car (2 maximum). All drivers were permitted to drive 3 hours per stint (maximum) with all refuelling and pit stops included. All drivers were required to take a MINIMUM REST TIME of 2 hours (whether driving 1 or 2 cars).[2]
New in 2012: There was an exciting new "Top-40" qualifying format for the 40 fastest cars on the starting grid, which took place, Friday, after the first 2 qualifying sessions: "the 40 fastest teams will battle it out on Friday afternoon for the positions at the front end of starting group 1".[3]
As in previous years, the Top 40 Qualifying cars eligible to start, must have flashing lights installed (for better identification of the Top 40 competitors) behind the windscreen on the passenger’s side.[2]
In 2012, there were 28 classes split into 4 divisions.
