Red Bull's extensive Austrian Grand Prix upgrade package felt like a "B-spec" car, according to the team's former mechanic Calum Nicholas, who suspects a hidden weight reduction programme played a big part in the team's return to form.
The Milton Keynes outfit arrived at the Red Bull Ring with a substantial list of updates. The official FIA documentation listed seven modifications, heavily targeting flow conditioning. The revisions featured changes to the sidepod inlets, engine cover, floor top and underside, rear corners and rear suspension fairings.
