Look beneath the squiggles of the Red Bull-Renault RB11's monochrome dazzle testing livery, and it's clear that the four-time champion team's new design is aggressive, especially with its nose treatment, sidepods and front brake ducts.
While Red Bull was the only team to deny Mercedes wins in 2014, outgoing technical director Adrian Newey estimated its peak power deficit was around 10 per cent, worth nearly six tenths of a second per lap. Windtunnel gains of the same magnitude are hard to come by, and Mercedes also gained ground in what is usually Red Bull's trump card area of aerodynamics last year. A big step is required for 2015.
Since 2009 Red Bull has set the bar for aerodynamic and chassis performance, and its four subsequent championships were all won with cars exploiting the Renault engine's exhaust gases to create downforce. With this advantage negated by 2014's new power unit and aero regulations, Red Bull was left with a huge loss in downforce, a lack of power, and unreliability.
