Mercedes announced on 16 November 2009 that it had purchased a controlling stake in Brawn GP, returning to Formula 1 as a full works team for the 2010 season.
The timing was extraordinary. Brawn GP had just completed one of the sport’s great one-season stories, winning both championships after rising from the remains of Honda’s withdrawn works team. Mercedes had supplied the engine for that title run and now moved to take control of the operation itself.
From rescue team to factory project
The purchase by Daimler and Aabar gave Mercedes control of a lean, championship-winning organisation based at Brackley. It also connected the chassis team more directly with Mercedes’ engine operation at Brixworth. That structure would become one of the most important technical foundations in modern Formula 1.
At first, the new Mercedes works team was not dominant. The early seasons were uneven, and the project had to build staffing, facilities and competitive habits. But the decision gave Mercedes the platform it needed before the 2014 hybrid regulations transformed the championship.
The deal behind a dynasty
With hindsight, the Brawn GP purchase is one of the decisive business moves of modern F1. It turned a rescued team into a manufacturer programme, preserved the Brackley operation and set up the structure that later carried Lewis Hamilton, Nico Rosberg and Mercedes through an era of extraordinary success.
On paper, it was an acquisition. In championship terms, it was the start of a dynasty with a very sensible invoice attached.
