Lotus continued its struggle with problems which have plagued the Enstone based team since the season kicked off. They intended to overcome their overheating problems and improve straight line speed.
Although the majority of teams used an extremely tight rear end thanks to the low temperatures in Belgium, Lotus had to open it extremely wide. The air outings are asymmetrical as the left one is almost twice as big as the right one. The team still encounter overheating issues: that is why they are deemed to give up aerodynamic downforce in favor of reliability.
Similar to Red Bull Lotus also run an extreme, Monza-spec rear wing to compensate the power deficit. Its main plane is almost horizontal and its flap is massively reduced in height. The endplates featured two slots and the single support pillar housed a very basic, one-element monkey seat.
