McLaren MP4-23 - rear bodywork 11 January 2008
Compared to the MP4-22, the rear of the car has been visibly lowered, with the exhaust pipes now placed further to the side. There are new movable covers (1), which could be replaced with cooling slits as the season progresses. The winglet behind the venting chimney (2) has also been refined. Rather than being curved, as on the MP4-22, the profile of its top edge is now completely flat. This increases the quantity and pressure of the airflow directed towards the rear wing, and uses the low pressure of the exiting hot exhaust gasses to accelerate that airflow.
