Wolff says Mercedes need to be "vigilant" of reliability issues
Toto Wolff has said that Mercedes must be careful not to get complacent and suffer from reliability issues this weekend at Silverstone.
Although Mercedes haven't suffered problems with their cars that would cause them to lose points or wins, Wolff has revealed that they have had plenty of small issues.
According to Crash.net, Wolff said: “We've also had a number of reliability issues that could have easily robbed us of a considerable amount of points, so we know that we need to stay vigilant and perform to the best of our abilities if we want to be in the fight this weekend.
“Austria exposed the biggest vulnerability of our car and it meant we couldn't challenge for the win at any point of the weekend.
“We've been working on our cooling for a while, but the combination of high temperatures and altitude in Spielberg ultimately meant that we had to do too much temperature management to be competitive.
“We will continue to work on this to have a better fighting chance at future races in the heat.”
