Ferrari F14 T - Montreal engine cover 09 June 2014
In an effort to improve the efficiency of their overall package, Ferrari tested a much tighter-fitting engine cover in Montreal, featuring longer sidepods and - as can be seen in the main drawing - extending further at the rear of the car, finishing inside the rear tyres. The main function of the new configuration was to help the overall cooling, although that came at the cost of downforce. It would therefore only have been of use in Montreal and Monza, due to the higher average speeds of the two tracks. Ferrari, however, decided the package didn't offer enough benefit in terms of cooling, and reverted back to their original configuration (inset).
