Jenson Button and Sergio Pérez unveiled the car, showing that it is a re-design of the MP4-27, last season's car.
McLaren have become the first team to use the new vanity panels allowed this season, as the team have decided to go for a higher nose which is stepped. A similar version to Ferrari's pull rod suspension system from the F2012 is being used on the MP4-28, and the sidepods and the rear bodywork have also been updated.
Jenson Button said: we were extremely strong throughout the whole of the 2012 season, but, for one reason or another, we couldnt quite pull it all together to challenge for the championships."
"Thats something we want to address for 2013. Ive seen just how closely everybody has been working together on this car, and I think weve got the basis for a very strong season."
"This years car is the best weve ever made - I know the engineers have left absolutely no stone unturned in wringing every ounce of performance from every available area. I cannot wait to get behind the wheel and attempt to carry forward the incredible legacy that lives beneath the skin of every single man and woman who works at McLaren."
Well be working extremely hard during the pre-season to ensure we go to the first race with bulletproof reliability. Operationally, too, I think weve learned and developed from last year, and that will help us run a much smoother and stronger campaign.
Sergio Pérez, who will take part in his debut race for McLaren in Melbourne said, "for me, this is a great day, In fact, every day this year has been great: Ive been working hard with my new team to get everything ready for the start of the 2013 season - and its been an incredible journey to get to know this incredible organisation."
The 2013 season will be McLaren's 50th, and they will be hoping to take some trophies back to their Woking base.
