The MP4-28 features significant revisions compared to the MP4-27 as the team felt that the MP4-27 had reached the end of its development cycle, and that starting over would give the MP4-28 a wider scope for development.[13] A pullrod front suspension similar to that of the Ferrari F2012 was introduced, the sidepods were revised to improve airflow over the rear of the car, while the rear suspension geometry was reconfigured to be more aerodynamic whilst incorporating a wishbone system designed to manage rear tyre wear by adding camber to the rear wheels as the speed increases, and relax as the car decelerates.[14] The car's centre of gravity was altered by reducing the weight of the rollhoop and engine cover, allowing the team to raise the car's nose.
