Disastrous is the only word to describe Mercedes' result during the Austrian Grand Prix weekend, with another strategic blunder and a double retirement after running one-two in the early stages. But the team has a very good reason to be extremely happy with one aspect of the weekend.
The major aerodynamic upgrade package introduced at the start of Friday practice worked very well and, on top of the phase 2.1 engine introduced for the French GP a weekend earlier, it suggests Mercedes has taken a potentially decisive step forward in terms of pace.
After all, the ongoing development war between Mercedes, Ferrari and Red Bull is what will decide the outcome of this year's championship. Long gone are the days of a single mid-season update, which was often called the B-spec.
