Herta's Cadillac hopes fade as Bottas fears Aston leapColton Herta will return to Cadillac's Formula 1 car in Hungary, but his intended path towards a full-time seat in 2027 is becoming increasingly uncertain. Herta joined Cadillac after a successful IndyCar career and was widely regarded as being prepared for a future Formula 1 race seat. That could strengthen Bottas' position after the Finn recently dismissed rumours that Herta was being prepared to replace him as complete bullsh*t . Bottas' immediate concern is not his own Cadillac future, but Aston Martin's enormous upgrade package debuting in Hungary. Bottas admitted he is worried the Adrian Newey-led overhaul could abruptly leave Cadillac dead last.
