If the British Geological Survey's seismologists picked up any tremors in Warwickshire last month they can more than likely be explained by Aston Martin's new chief executive striding into his Gaydon office for the first time.
Tobias Moers has arrived from Mercedes' AMG business with a formidable reputation. A results-driven businessman who doesn't fear a challenge - and doesn't mind being feared - and whom executive chairman Lawrence Stroll hand-picked from a very short shortlist.
The arrival of 54-year-old German Moers should also have shaken Milton Keynes, Maranello and Enstone. For all the distracted talk about Racing Point's 'Pink Mercedes', the competition should be rather more concerned about the overall ambitions of Stroll, Moers, and their technical partners at Daimler, to position Aston Martin at the forefront of Formula 1.
