Red Bull Racing unveiled their new RB11 at the first test ahead of the new F1 season in Jerez, Spain on Sunday morning.
Donning a unique livery just for testing, Daniel Ricciardo completed a handful of installation laps around the Spanish circuit.
“The design of the RB11 has been very much about understanding what we learned from last season, which was a big regulation change as far as the power unit is concerned and the packaging that goes with that and setting about optimising the car from those lessons,” said Chief Technical Officer Adrian Newey.
“We’ve been pushing to the limit as usual,” added Team Principal Christian Horner.
“We had a very tight timescale for the car to be prepared in time for the first test, but that’s normal in this team. If you’re not on the limit you’re not trying hard enough.”
