"The actions we need to take next year to be competitive [are] quite extreme," the two-time champion said. "For big problems you need big solutions, and I think maybe that helped a bit for the big solutions." Media playback is not supported on this device McLaren's season featured a constant stream of reliability problems, grid penalties for using too many engine parts and uncompetitive performances, largely as a result of the fact Honda's engine was by far the worst in the sport. McLaren's best results were a fifth place each for Alonso and team-mate Jenson Button. Alonso, in an exclusive interview for the BBC F1 Review show, admitted that he "knew they could broadcast" his message in Japan, when he likened the Honda power-unit to one from the GP2 feeder formula, where engines have a third less power than in F1. But he added: "A lot of radio messages they didn't broadcast, a lot of in-laps where we were very thankful of the team because it was very difficult. "Sometimes they change three engines, we were taking one point, two point, close to the points. A lot of positive messages they never broadcast. In Japan, when they broadcast that, probably I knew they could broadcast it." Button, who also made some withering remarks about the car's performance over the radio and joined Alonso in waving from the podium in Brazil after both were knocked out in the first part of qualifying, said: "Most of the stuff I've said has been useful to the team.

Alonso said that McLaren's performance had made it difficult for him to maintain in 2015 the high standards for which he has become famous in F1. "I don't think it was the best of me," he said. "I had some good races but here and there not consistent enough." He singled out his qualifying lap in Japan, which he said at the time was one of the best of his career, and his race at the US Grand Prix as his personal highlights of his season. "In Suzuka, one of the best," Alonso said. "In Austin, it was one of the best - for the first 20 laps in the damp conditions, eight or nine of them I was quicker than Lewis (Hamilton), who was leading the race. "But I could not keep that top level of performance consistently enough. "Sometimes because of the lack of laps, sometimes because of
