 Alonso returned to the team for the Malaysian Grand Prix , where the engine was retuned to operate at a higher level of performance and the team introduced a range of aerodynamic updates including sidepod fins and a new front wing . However , Alonso and Button still qualified on the penultimate row of the grid ahead of the Manor Marussia drivers Roberto Merhi and Will Stevens . Both cars retired from the race with mechanical problems . The team did not score any points during the first round of flyaway races , struggling with poor reliability and a lack of engine performance ; the Chinese Grand Prix was the only race where both cars were classified as finishing . Although Alonso repeated the team 's best finish of eleventh place in Bahrain , any hope of improved performance was arrested with the start of the European season at the next round in Spain , where Button finished sixteenth and Alonso retired with brake problems .
