On the press release, the British car manufacturer said this concept was created to introduce Jaguar's new, highly-advanced, modular aluminum architecture, but i think there's more behind the C-X17. I believe this is the first time we will see how the company's upcoming crossover will look like.
Jaguar will also bring the XJR, XFR-S, XF Sportbrake and the F-TYPE to Frankfurt. There was a rumor saying that the production version of the F-Type coupe was going to be shown in Germany, but for now that seems to be false.
The live presentation will take place on September 9, around 17h CET.
