F1 has two big issues for 09

Two important changes are slated in Formula One next season. Alongside the return of slick tires, F1 will see the introduction of aerodynamic innovations and the Kinetic Energy Recovery System, KERS.

However, BMW Motorsport Director Mario Theissen stated that unless teams are already hard at work on both these issues, they will find themselves in trouble with the development of their car for the 2009 season.

"The two big issues are KERS and the 2009 aerodynamics package," he said on the team’s official website. “Anyone who has not yet started to work on aerodynamics will really struggle to be ready in time."

Theissen also knows what the main focus of development on the successor to the F1.08 will be…

"The main difference is definitely the omission of all additional aerodynamic elements. This will result in the bodywork having a different appearance."
