Sochi, Russia - Mercedes team boss Toto Wolff isn't taking anything for granted despite Lewis Hamilton leading the Formula One standings by 40 points with just six races left. The Russian Grand Prix has been won every year by the Silver Arrows, but a change of date could cause problems.
Mercedes has won at Sochi on each of the four occasions the Russian Grand Prix has taken place but team chief Toto Wolff says it cannot rest on its laurels as Lewis Hamilton closes in on a fifth Formula One title. Victory for Hamilton last time out in Singapore, after a stunning pole lap which came out of nowhere, put him 40 points ahead of Ferrari's Sebastian Vettel with six races remaining this season.
Hamilton won in 2014 and 2015 in the Russian Black Sea resort when the race took place in October. It was moved to May and April in the past two years, when team-mates Nico Rosberg and Valtteri Bottas prevailed. Wolff is a little concerned by the switch in date.
"With the race being held in late September, we're going back to weather conditions that will be similar to those of 2014 and 2015, when the Russian Grand Prix took place in early October," he said. "We don't have any data from the current regulation cars in those conditions in Sochi, so this adds another challenge to the race.
"We have a good track record in Sochi but we know that Ferrari and Red Bull will give it everything to break our winning streak, so we must fight as hard as ever to make sure we bring home as many points as possible."
