It is now 15 years since the first new Mini was produced in the company’s Oxford plant.
The BMW Group is also marking its 100th year this year and the automaker has played a key role in the success of the revamped Mini.
More than 2.5 million Minis have been produced at the UK plant, with 80 per cent exported to more than a 100 different countries.
Frank Bachmann, managing director of Mini in Oxford, said: "Mini is an iconic British brand that has made a remarkable journey over the past 15 years. In that time we’ve more than doubled our capacity and gone from producing just one model to an entire range of MINIs that have proved hugely popular with customers around the world."
The plant produces around 1,000 cars per day and the model remains popular with buyers.
Mr Bachmann added: "We celebrate what’s been achieved so far and look forward to an even brighter future here in Oxford – the heart of Mini production."
