The W01 engine cover is mainly consisted of 4 different parts , the upper one with the pointed extension ( I prefer to call this extension humpback fin marked with No1 ) , the double side parts ( No 2 ) , the exhaust covers at both sides ( No3 , to permit mechanics access the exhaust zone easily) and the black colored gearbox covers ( No 4 ) . At cockpit sides there are two removable covers that can be easily replaced with vented ones to aid cooling in hot conditions . To construct a complete W01 engine cover mechanics have to combine 8 parts in total .
The new major Spanish aero package included also new sidepod panels (the third version since the launch of the W01 ) to increase the volume of air passing inside the zone formed by the panel and the sidepod surface in a way to change aero distribution towards the rear .
Those new panels were retained till the end of the season .
Part of the new major update package launched at Spain was also a new floor splitter . The longer wheelbase made the team to change the car’s weight distribution and to remove some of the ballast housed inside the splitter .As a consequence the splitter was lowered in height and became more efficient aerodynamically with a smaller frontal section as it had to house much less ballast . Finally the side vented sections were also rejected .
W01’s initially featured a large and boxy floor splitter with wavy sides to guide airflow more efficiently under the car . The oversized Mercedes splitter , compared to other teams much smaller design , was the result of the team’s decision to house a really large amount of ballast inside it . During late winter testing and at the first 2010 race at Sakhir , the W01 had an updated splitter with additional holed side sections to improve further the aero efficiency of the car’s underbody .
The Mercedes W01 car had been launched featuring 2009 BGP001 panels design and it was obvious that a new panel would show up soon before the first 2010 race and so it did happen .
The new panel which was also tried during late winter tests has a more boxy profile with the intense rear cut to be vanished . Another major difference was the addition of an extra winglet extending towards the inner zone to smoothen the air circulation between the panel and the sidepod surface . Lastly the lower panel section is inclined in a more intense way towards the inner to alter airflow around the sidepod bottoms , a change triggered by the introduction of a new diffuser at Sakhir also .
