Changes to the technical regulations for this season dictate that 2018’s cars will not feature the shark-fin engine covers and accompanying T-wings that became such a common sight last year. However, that may not mean we have seen the last of the latter… In the drawing below, the green and orange highlighted areas show where bodywork is restricted under the 2018 technical regulations. These were less restricted last year: which led to the loopholes responsible for the emergence of the shark fins and T-wings.

However, even with the tweaks to the rules there remains an area – immediately between the rear wheels where the aforementioned green and orange areas intersect – that can be exploited by the teams. And it’s one that has already been used – by Williams last season.
