Daniel Ricciardo says Red Bull's chassis improved so much throughout the season that it was as good as the Mercedes by the end of the year.
Red Bull struggled at the start of 2015 with an uncompetitive power unit, but Ricciardo was also unhappy with the car's handling. As the season wore on, Red Bull's results improved with a double podium in Hungary, second place for Ricciardo in Singapore and a spell leading in the wet in the United States.
Asked about his feelings regarding this year's Red Bull chassis, Ricciardo replied: "It’s a tough one.
"It’s frustrating. If we had more power we could probably win races, but at the same time it’s quite cool that we know we have good guys in the team and we have a good car. It’s frustrating but it is quite rewarding because the guys know the work they are doing is working.
"For me, we didn’t have the quickest car at the start of the year, the chassis had some deficiencies, but I think what the team has done is make the chassis pretty much back to where it was last year, which is as good as the Mercedes."
Red Bull will continue to run a Renault power unit in 2016, though the engine will be badged as a Tag Heuer.
