The next-generation X5 will use the same platform as the 7 Series, on the CLAR (cluster architecture) platform. This platform supports steel, aluminium, carbonfibre and magnesium construction, so it's likely there will be a sizeable reduction in weight compared with the lightest of the current X5s, the xDrive35i, which tips the scales at 2030kg.
Another recent sighting was of an X5 M. It was seen driving near the brand's test centre close to the Nürburgring with production-spec bodywork, suggesting the top model, which is predicted to have up to 600bhp from its twin-turbocharged V8 engine, could be launched soon after or alongside the regular car.
