Jaguar is only months away from revealing next-generation XJ saloon, which is scheduled for a debut on July 9th at a special presentation in London before going on sale by the end of the year. We’ve already had a glimpse at the final version following the release of an official teaser at last week’s Shanghai Motor Show, and now a prototype has been spotting racking up some laps at Germany’s Nurburgring circuit.

The new XJ will be the first model feature the next-generation of Jaguar's aerospace-inspired aluminum body architecture, and it will be available with the carmaker’s latest 3.0L V6 turbodiesel and 510hp (380kW) 5.0L supercharged petrol V8. A plug-in hybrid variant is also rumored to be launched one year after the regular model, though no confirmation has been made on this yet.

As indicated by the past teaser shot, Jaguar designers have focused on alleviating many of the current XJ’s criticisms – namely the outdated styling and lack of engine options. One insider who had seen concept sketches for the car described it as looking like the C-XF’s features had been draped over an Aston Martin Rapide.

Previous spy shots revealed that the headlights will likely share some XF traits, though the rear could get fully-modern LED units of a unique design, possibly sharing hints of the Bentley Continental GT Flying Spur – one of the cars Jaguar would eventually like to rival with its new XJ.

High-tech features inside are said to include pressure sensing buttons, combined with backlit glass panels and the retracting transmission selector knob used in the XF.
