Mercedes will be in a position to win the Formula One world championship in 2014, according to company boss Dieter Zetsche.
Speaking at the Detroit motor show, Zetsche admitted that the team's results last year, where it finished fifth in the constructors' championship and scored one win with Nico Rosberg, were not good enough.
"Formula One is a very visible platform, and there's no doubt we spend a lot of marketing budget on competing as we consider it close to our core business," said Zetsche.
"But as its so visible people see pretty quickly if you succeed or not, and if the results are up to your expectations. For Mercedes those expectations must be that we are up there at every race competing for victory.
"Even though we had one win last year, you cannot say we were in a position to be considered winners everywhere. So that is why we have made changes - a new driver, a new chairman and more to come.
"What we saw was that the engine was the best, or up with the best, and drivers who were among the best. The real problem lay with the chassis and we are working on that.
