The BBC takes a look inside the new vehicle, which is going to be produced at BMW's plant at Cowley.
Workers at the factory that produces the Mini car have backed a three-year pay deal, according to the Unite union.
Staff at the Cowley plant in Oxford have voted in favour of a pay rise that is worth a minimum of 10% over the three years.
Unite regional officer Fred Hanna said: "This pay deal was the result of intensive pay negotiations between Unite and BMW and recognises the important role of the Cowley workforce within the German car giant.
"Not only is it inflation-proofed, but agency workers at the Cowley site are also covered and will receive the same bonus payments that permanent employees get."

German carmaker BMW has reported a rise in 1.1% rise in worldwide group sales for 2018 to 2,490,664 vehicles.
Sales of the BMW-branded vehicles in particular rose 1.8% in 2018 to 2,125,026 vehicles, with sales in December rising by 1.3% over the Christmas period.
However, sales for the December trading period for the group fell by 0.7% overall, due to an 11.3% fall in sales of Mini-branded cars.
German carmaker BMW's third-quarter operating profit fell 27% to €1.75bn, below analyst expectations, as higher research and development expenses weighed on earnings.
Last month BMW warned its pre-tax profit would fall this year, against earlier expectations for a flat outcome, and cut its profit margin guidance for cars, blaming intense price competition.
