Mercedes is determined not to let the cracks that have shown in recent races widen sufficiently to give its rivals hope of success in the run-in to Abu Dhabi's F1 finale next month.
With the constructors' title already squirreled away in Sochi, the Three Pointed Star has already hit 50 per cent of its target for the season, and could wrap up the other half should Lewis Hamilton garner the points he needs in Austin this weekend, but team boss Toto Wolff is adamant that there are still aspects of the overall performance that need to be tightened up – especially with Ferrari's Sebastian Vettel still in with a mathematical chance of stealing the drivers' title.
“It's been a proud week for everybody in Brackley, Brixworth and Stuttgart,” he noted, reflecting on the second successive teams' title, “We can talk about chassis and power units winning titles but, really, it's about people. Every one of those men and women is a deserved world champion, and we now have four races left to make sure our 2015 objectives are complete, with the drivers' title still on the line.”
Hamilton heads to Texas with a 66-point lead over Vettel, and needs to outscore the German by nine points to knock him out of contention, but Wolff is aware that Mercedes previous domination has begun to wear thin in recent weeks and is anxious to address those concerns.
“Two retirements from the last three races is not up to our standards, and we must ensure that every little detail is covered to give [our drivers] that opportunity,” he insisted, “Lewis is within touching distance [of the title], but I know that his focus is only on winning the next race. For Nico, bad luck has played a big part this year and it would be a huge mountain to climb, but he is a fighter and we have seen many times that he will keep pushing until the very end.
“Of course, there is still a third party in the mix and we, as a team, must make absolutely sure that our drivers have everything they need to make sure it's a Silver Arrow that comes out on top.”
