In the past few months there’s been a flurry of news about Jaguar Land Rover’s expanding production base.

The company has already opened a factory in Changshu, China, with local partner Chery. The Range Rover Evoque and its sister car, the Land Rover Discovery Sport, are being built there, and, eventually, the long-wheelbase version of the new XF.

However, the capacity of Changshu is limited to around 130,000 units at the moment and the localised production is mostly needed to avoid China’s significant import taxes.

Work on building a small plant in Brazil is also under way; this should start producing Discovery Sport models in 2016. The plant is quite modest, however, with an initial capacity of 24,000 units a year.

In addition, JLR has just signed a deal with Austrian company Magna to build vehicles under contract. Based in Graz, Magna has been building the Mini Countryman since it was launched and also builds other cars, including the Mercedes-Benz G-Class.

The British company won’t say what will be made at Graz, but the new Evoque Cabriolet is one of the most likely candidates.

There have been reports that JLR is considering a factory in Mexico. Although there's no confirmation, Mexico’s low wages and the North American free trade deal make it an ideal country from which to export to the US. Indeed, it has just been announced that Ford is moving production of the Focus and C-Max from North America to Mexico.

But none of JLR’s overseas production facilities will be as big as the one currently being finalised for a site that's tipped to be somewhere in eastern Europe.

Tipped to be a £950 million investment and have a capacity of up to 350,000 units annually, the new factory will be in either Poland or Slovakia, according to local media reports.

No car maker, especially when it is building lower-value vehicles, can ignore wages that could be as low as £6.25 per hour in Poland and £7.50 in Slovakia, compared with as much as £18 per hour in the UK.

Although neither country has publicly announced that it is in talks with JLR, Polish deputy prime minister  Janusz Piechocinski said at the end of June that the country had reached the sixth round of negotiations with a premium car manufacturer for the construction of a new plant.
