2015 Jaguar ‘XS’ Spied Testing

A Jaguar prototype spotted in cold-weather testing has given us a new look at the carmaker's upcoming mid-sized sedan, which will slot in below the XF. 

Wearing XF bodywork but measuring much shorter than a production XF, the prototype also sports a lower ride height and different exhaust plumbing, confirming that this is anything but an XF underneath. 

With proportions similar to the Mercedes-Benz C-class and BMW 3 Series, the new Jag will also be rear-wheel drive, with an AWD option in some markets.
