Although they haven’t come out and said that the weight of their car and driver at the recent season opening Australian Grand Prix was the reason they weren’t on par with the race winning Ferrari driven by Sebastian Vettel, Mercedes boss Toto Wolff has conceded that they need to reduce the weight of their car by a few kilograms.

Speaking to the German press, Wolff explained that their new car is not at the minimal weight allowed by the FIA, 728kg, instead it was 5 kg’s over, so work is underway to reduce the weight in the hope it will give them back the edge they have had over their rivals for the past three successive seasons.

Lewis Hamilton was heard telling the team over the radio at Albert Park that he was struggling for grip, causing him to pit a lot earlier than his rival, the added weight wouldn’t be helping the situation at all.

Mercedes is not the only car carrying a bit of extra weight however, with Force India also admitting the same concerns.
