The Brazilian Grand Prix will continue to be held at Interlagos until 2020 after the circuit signed a new contract.

The old contract for the race was due to expire in 2014, but Bernie Ecclestone has agreed a new deal with Sao Paulo mayor Fernando Haddad that will ensure Interlagos remains on the Formula One calendar for the next seven seasons.

A key condition of the new agreement is the construction of a new pit and paddock complex at the circuit. The new development will be located on the straight between turns 3 and 4, with construction due to begin next year and be completed in time for the 2015 race.

Interlagos first hosted a non-championship grand prix in 1972 and then a championship race the year after. It has been the venue of the Brazilian Grand Prix on 30 occasions in total.
