Mercedes remains humble - Wolff
Toto Wolff is adamant Mercedes is not taking anything for granted despite being the outstanding performer in the opening two pre-season tests of 2014.
While Renault-powered teams such as reigning champions Red Bull have struggled, Mercedes' works team has undoubtedly made the most headway in Jerez and Bahrain. The gulf was so big at stages that while Mercedes was running its first race simulation of 2014, Lotus was recording its first testing laps of the pre-season.
Their performances so far would arguably make Mercedes early title favourites but team director Wolff insists no team has ever won the Formula One title in the opening two months of the year, hinting there is still plenty for the team to work on at the second Bahrain test this week.
"Humility is the word that comes to mind. There have been many 'test world champions' in the past," Wolff told German news agency DPA. "We are very aware that Ferrari and the Renault teams will come back. It is only a matter of time and I don't doubt that for a second."
"This team [Red Bull] has won the world championship four times and has one of the best drivers in the field. The issue of reliability is far from solved. I assume that the first issue has to be getting to the end of the race. We have had some good tests but we have no reason to fall into jubilation."
