Early indications suggest world champions Red Bull may be playing catch up to their nearest rivals.
As Mercedes and Ferrari made for a large proportion of the running on the opening day of pre-season testing, Sebastian Vettel was consigned to three one lap tours of the Jerez circuit in the final 20 minutes on Tuesday.
Some indications over New Year suggested the Milton Keynes based team were running late with their latest car, the RB10, with some reports team boss Christian Horner had asked for a week delay of this week's test.
However, on Tuesday, just ten days after passing the necessary FIA crash tests, the new car was in the south of Spain but it was obvious engineers were still getting to grips with designer Adrian Newey's latest creation.
Indeed mechanics were working well into the night on Monday to put the 10th Red Bull car together in time for today's launch.
When asked why Red Bull were stuck in the garage while their rivals set about discovering what their new cars were like, Horner said it was because of a "silly" installation problem.
Vettel went into a little more detail explaining one of the thousands of parts that make up the RB10 had been wrongly mounted.
"That we managed to put it together in time is a huge achievement," argued team boss Christian Horner.
Vettel also spoke how he believes fans will be unable to grasp the complexity of Formula 1's new cars with the new V6 power units and aerodynamic regulations, an issue the German added could be made worse if reliability remains poor at the start of the season itself.
"If even the engineers are having difficulty, the audience will obviously understand even less," said the four-time champion.
Red Bull were not the only team struggling to understand their latest machinery as McLaren failed even a single lap around Jerez on Tuesday.
It is believed that while they had the car working back in Britain, the car is now suffering hydraulic and electrical issues with the new engine units.
