On the surface, a second consecutive winter of minimal regulatory change may appear to ease the pressure on the Formula One community. The reality, however, is quite the opposite. Progress under such conditions is a game of diminishing returns - making the quest for every millisecond of performance ever-more crucial. "The biggest challenge for the team over the winter has been finding how we can extract more performance from what was already a very strong Power Unit and chassis concept", confirms Head of Mercedes-Benz Motorsport, Toto Wolff. "The regulations have remained mostly stable for another year, so the development curve has naturally started to level out slightly. But as a group of competitive racers, this is the sort of challenge we love - to find every last bit of performance. "After the success of the past two seasons, the obvious target is to build on what we have achieved so far - to continue to win races and Championships. But you can never take anything for granted in this sport - or rely on past success. Right now, all points are reset to zero. We haven't even begun testing yet, so we have no benchmark against the competition. But we can be certain that they will be stronger than ever, so we need to do the best job out there. In Melbourne, we will see. As they say, when the flag drops... "We gained confidence after the first Championship title in 2014 and therefore approached 2015 in a slightly different way. But our core philosophy remained the same and 2016 is no different. We are confident in our people - but we always take a 'glass half empty' approach. We remain humble, feet on the ground, pushing hard to develop everything from the cars to our wider capability as an organisation in the long term."
