Interesting......After seeing those autoweek pictures, I think that everything except for the front fascia and the detailing (like in the lights and in the interior) represent the rear car. It almost looks as if the fascia is an add-on, not necessarily meant to be there but added for visual interest.
No doubt Jaguar took some inspiration from Aston Martin in designing this model, and that's a good thing. I really hope they stay true to this concept when the production model comes around. Jaguar's lineup could definitely use this model, but it'll take more than this to save them...
Can you call it 'inspiration', if they were both designed by the same guy?
This will help Jaguar on it's way back to profitability, but the next S-Type is widely acknowledged to be the crucial car to pull them out of the red. According to the editorial in last month's Top Gear magazine, those who have seen it, all say it's the most beautiful car Ian Callum's ever designed.
