After using one Drag Reduction System (DRS) zone in 2011, the circuit featured two zones for the 2012 race. These were located along the main straight and between Turns 2 and 3, with a single detection point for both zones—similar to the format trialled at the 2011 Canadian and European Grands Prix—located at the entry to Turn 14. Other modifications to the circuit included the introduction of thicker, spongier astroturf on the exit of several corners to discourage drivers from driving beyond the limits of the circuit. Tyre supplier Pirelli brought its white-banded medium compound tyre as the harder "prime" tyre and the yellow-banded soft compound as the softer "option" compound, whereas last year the "prime" compound was the silver-banded hard compound tyre.
