After a difficult opening pre-season test at Jerez, Red Bull’s chief designer Adrian Newey is struggling to completely get to grips with the issues on the RB10.

The world champions had a disastrous week at Jerez completing just 20 laps over four days as well as finishing slowest on the timings.

The poor reliability seems to be a mix of the usual tight, aerodynamic design of Newey’s RB10 and the cooling issues and other problems engine supplier Renault are having with their new V6 power unit.

“We need to redesign certain things,” Red Bull’s Helmut Marko told Germany’s Auto Bild.

“It’s annoying, but I keep remembering that in 2010 we also did not test in the first week.”

History of course tells us that despite missing the opening test that year, Red Bull and Sebastian Vettel went on to claim the first of four straight world titles, in one of the closest title battles in years.

Despite that positive thought, however, things look to be a little more serious this time. Auto Bild reports Newey as saying he has “no idea” if he can sort out all of the RB10′s issues to his very high standard.

Marko, however, has confidence in the 55-year-old.

“Adrian’s concept is good in principle — I think our car is very elegant, and beautiful cars are usually also fast.”

The sense of belief that Red Bull can solve their issues is not just within the Milton Keynes squad neither as their rivals also think the RB10 will be right in the mix.

“Red Bull and Renault have had a big handicap not to have driven the four days, but it is too early to talk about overturning hierarchies,” said Mercedes’ Toto Wolff.

“It’s not good for F1 that a manufacturer is in trouble, but I am sure they will come back strongly. Hopefully a bit less than before!” he added.

Speaking about their driver Sebastian Vettel the Austrian continued: “First, they have an outstanding driver.

“Secondly, they have put together a group of people that works very well. Thirdly, they have the resources from the parent company.

“So there’s no reason that Red Bull will not once again be the benchmark,” he concluded.
