Mini says its operations are currently unaffected at its Oxford plant following the Brexit vote and will continue to be for some time until it's clear how the UK's exit from the European Union (EU) proceeds.
Mini boss Peter Schwarzenbauer said it remained "business as usual".
He added: "For the time being, nothing has changed. I could consider thousands of different scenarios, but we don't know what will happen."
Schwarzenbauer said Mini had made significant investments in modernising its plant in the past two to three years and there was no imminent decision to be made on any future cash injections, because Mini simply "does not have any big investments in front of us".
This compares to Nissan, which had an imminent investment decision to make regarding future model production at its Sunderland plant, prompting it to seek assurances from the British government on Brexit before making a decision.
Schwarzenbauer said Mini was in a similar situation in the US with the recent election of Donald Trump as president.
"Nobody knows what really will happen at the end of the day," said Schwarzenbauer, who pointed to the fact that BMW already has a strong presence in the US. Its Spartanburg SUV plant is the largest BMW factory in the world.
