It is common practice to monitor tyre temperatures, but after last year's events in the US, it was seen as even more important at Indianapolis this year - not only to ensure safety, but also to try and extract maximum performance from the tyres. During practice all the teams constantly monitored...
A heavily revised version for Indy, designed to increase the car's high-speed performance, reportedly one of its weaker points to date. Compared with the previous design, the spoon profile (1) is now wider and slopes down less abruptly than before. The small winglets (2) on the inner edge of the...
Honda have tried two configurations at Indianapolis, a low-downforce one giving more straight-line speed on the main straight, and a high-downforce one providing more grip in the twisty infield section. The low-downforce version features a deep but smooth curved spoon profile at its centre, together...
A new version for Indianapolis, featuring a completely flat main profile and flap. This provides less downforce, but at the same time reduces drag, hence improving top speed on the long straight. To guarantee adequate grip, especially in the slow infield section, both front and rear wings feature...
One of the changes Renault have brought to the North American races is this rear wing, with a revised wing profile, flap and endplates. The profile is now flat, rather than bending downwards at its extremities. This helps reduce drag, with minimal downforce loss. The endplates lose their wide slit,...
For Indy, the diffuser's side walls have been dramatically revised. Gone is the knife-edge profile at the base of the central section and in its place is a small, upward-curving lip. The diffuser is no longer parallel with the ground over its entire length. Instead it bends upwards, reducing the...
