Red Bull has publicly debuted its RB12 as it braces for a challenging year after a troubled 2015 season.
Red Bull, which last week unveiled its 2016 livery in London, claimed four successive titles between 2010 and 2013 but slipped behind Mercedes when the sport introduced V6 power units in 2014.
The outfit regressed further in 2015 as it slipped to fourth in the standings and finished on the podium only twice.
That led to an acrimonious split with power unit supplier Renault, though the French manufacturer will continue to provide engines, albeit under the guise of new Red Bull partner Tag Heuer.
"Obviously the late engine decision last year was a challenge but we found a solution in time and the whole team has worked incredibly hard to recover over the winter," said team boss Christian Horner.
"Therefore, we’re looking to build on the significant progress we made in the second half of 2015 and to carry that momentum into the early races of this season.
"My hopes for this season are that we genuinely make progress from where we were last year; that we get our heads down and we really develop the car well and hopefully with some performance coming on the power unit side as well, that will allow us to get closer to some of our immediate rivals."
Three-time race winner Daniel Ricciardo and Daniil Kvyat will race the RB12 this year.
