Mercedes GP team principal Ross Brawn is quietly confident his team have improved sufficiently on their below-par 2010 Formula One car but refrained from making any early predictions on the pace of the new MPG W02.
"With this car we've moved a good step forward with the construction, the weight, centre of gravity," he told the Press Association. "We've recovered a lot of the aerodynamic performance that was lost from the regulations. There are other things like the unity of the design groups, we've a second season with both drivers, and that helps."
Despite everyone having to acclimatise to changes in the new FIA regulations for this year's Formula 1 season, Brawn is content the 2011 challenger will power both Michael Shumacher and Nico Rosberg to better results than last year.
"It's about lots of things all coming together and moving in the right direction," he confirmed. "But you never know if it's enough. You never know if someone is going to make a strong breakthrough. But I'm comfortable we've made real progress over the last six months, and that this car is the culmination of that."
