The next-generation BMW X5 has been spotted again, this time outside the manufacturing plant in Spartanburg, South Carolina in the United States. where it’s set to be built. It appears that it has dropped yet more of its camouflage cladding, here revealing a larger pair of kidney grilles.

Additional use of aluminium, magnesium and carbon-fibre will make the upcoming BMW X5’s structure lighter and more rigid, according to company insiders who indicated so to our spy photographer sources. When it makes its debut, the upcoming X5 is said to weigh 230-270 kg less than the current model.

As par for the new model course, the X5 is also expected to grow in size for improved occupant and luggage accommodation, and in BMW tradition the X5 will feature nearly the full complement of the Munich marque’s four-, six- and eight-cylinder engines, the latter the reserve of the eventual X5 M successor. Petrol and diesel versions of the former will make up the bulk of orders, which will also include a hybrid version.

The unit pictured here could be an M Performance model in the mould of the M550i xDrive, which like the M5 also boasts of a 4.4 litre twin-turbocharged V8 petrol engine, albeit detuned. Here, it is distinguished by its blue brake calipers and a sportier wheel and tyre package.
