SHANGHAI, China -- Daniel Ricciardo says the Red Bull's lack of rear downforce is visible when comparing on-board footage of his laps with those of the Ferrari and Mercedes drivers.
Despite high expectations ahead of the season, Red Bull emerged as the third fastest team at the opening round in Australia with a significant gap to the front. Although the RB13's Renault power unit is lacking performance to its rivals, Ricciardo believes the aero package -- which has historically been a Red Bull strength -- is a key area where the team is lacking.
"I think for me at the moment we don't have enough rear grip, so downforce basically," he said.
