There will also be a phased increase in assembly line capacity.Details of the expansion will be unveiled in a fortnight by BMW's board director for production, Dr Norbert Reithofer, at a special event at the Oxford plant and will raise the German car maker's investment in the site to more than £400m.The Oxford plant has 4,500 employees and operates 11 shifts a week. But spare capacity at the factory has run out.The bulk of the investment will be in a second paint shop to unblock the biggest bottleneck in production at the Oxford plant. BMW, the German car giant, is to embark on a major expansion of its Mini factory in Oxford, which will involve investment of about £150m and create hundreds of jobs. The expansion is likely to increase the capacity of the plant to between 250,000 and 300,000 vehicles a year and follows soaring demand for the iconic car. Mini production last year reached nearly 190,000 after the introduction of a convertible version in the summer. Steve Davies, of Numis Securities, said: "Holding out for 60p may be a little optimistic: mid-50s is probably a more realistic figure unless a rival bidder emerges.".
