Renault Sport prepared the only development of its power unit-face to Austin. The French manufacturer spent 11 of the 12 tokens available and yet, Red Bull and Toro Rosso were dismissed by their use. The complicated conditions because of the hurricane, ‘Patricia’, and the eventual penalty were the reasons given for not using the new engine in the united States. Also mounted this engine in the GP of Mexico due to the lack of a set up prior and the own requirement of a circuit situated at a high altitude. on the occasion of the Brazilian GP, Red Bull will premiere the new engine of Renault.
The austrian team will mount the new unit of power, something that will not make your affiliate team. Toro Rosso will not make use of the new engine in the rest of the season. That does not diminish that for Red Bull it is a fundamental test. To check the evolutionary leap of the new power unit is a necessary step to face-to 2016, as the possibility of mount Renault engines of ‘white label’ is tangible. In fact, there is the possibility of seeing Renault to supply its combustion engine to the team, while Red Bull developed its own ERS.
The only unknown is the policy used by Red Bull at Interlagos. It is unknown if both Daniel Ricciardo as Daniil Kvyat will be using the new Renault engine, or whether on the contrary it will be only one of them in charge of checking the performance of the new power unit in the RB11. The use in one of the cars can serve as point of comparison and tends to be common practice in a good number of teams. Without going more far, Fernando Alonso had access to the new Honda engine before his teammate Jenson Button. We will see that decide to.
