If any car should have had the ability to set the top-speed mark on the straight from Tertre Rouge to the first chicane on Les Hunadieres, or the long curving run from Mulsanne down to Indianapolis, it should have been the current 997-generation 911 GT3 RSR—but it wasn’t. On the first night of qualifying, five Ferraris held the official top speed at an identical 299 km/h (just a hair under 186 mph), this despite the F430’s larger frontal area and slightly higher drag compared to the 911.
