Well, it is certainly very much like the aston. Obviously because the original DB7 designer Ian Callum is also the head of Jaguar design.
My design Critique:
The aluminium body is probably going to be good. Saves weight, increases rigitidy. Look at the new XJ. Jag did a fantastic job with the aluminium construction are are likely to do so here. (unlike the past generation audi A8, where no weight reductions, or handling improvements were apparent). Platform is probably similarly based on the Aston VH, as both are in the Ford Premier group.
I personally know that 440 bhp is very much enough. But these days, all people hear is about 500, even 600 bhp. By the time they make this into an XK (this is still concept) its competitors will be on top of them, unless that 440 is base and there is still a more powerful one. Look for the porsche 911 variants, Mercedes SL, Maserati GT, and BMW 6. It needs to be competitive in its field. 440 as a top model will NOT be enough. ie. SL55: 493, M6: 500.
The profile of the car is very classy, nice and curvacious. Looks good, looks beautiful, looks like an aston. So what. Astons look nice.
Headlight are ugly, as are those front air scoop things that look out of place. Grill, maybe too high; reminds way too much of a ford taurus. I wonder if they too that part from the ford parts bin... yikes. Side air outlets are a little wierd, sort of like the Range rover ones. I can live with them. Rear lights are pretty bad again. Althoughit may make loading easier, this lifting hatch makes it too much like a wagon or hatchback; I would prefer to see only the trunk lift, rather than the rear window as well.
Interior is a shock. Not a bit of wood. I disagree, Jag cant do this. Where is the polished wood and creamy conolly leather? "dimpled" aluminium sheets wont do. Jag, clean up your act and bring your market niche together. Jag owners want luxury, as much wood as a Rolls, and yet in a light and sporty vehicle. Unless I am old fashioned and wood isn't popular anymore. Good job on ditching the J gate. Manual isn't necessary, but a tiptronic is required.
Nice, but needs some changes before it can turn into an XK. Its a little too daring, obviously a concept will be.
