I came up with this :

Only a rough draft, but it seem's to work Ok, you can even 're-use' the rear quarter window ( rotated ) ... bonus ? ...
Add : Um - I might revise that window, as in the later sketch it didn't work so well ...


It should be a relatively simple job in cutting back to the sill line & then re-graft bits back in a suitable place. It will require some reworking of 'tray' in back though - I don't have any details of how that would go as yet ...

Add : I've also taken the top off the rear tail gate & spoiler and moved them forward, it could also be an option to make the rear window openable, not sure if it would work though ... ? ... It would also require re-hinging of the tailgate on bottom + checking to see if it opens with out hitting anything, like the bumper ...

More Details : It would primarily be based on the XV / Impreza platform, with the following makeup :
- Engine : XV : FB-20: 2.0 L H4 ( t/c Diesel ) ?
- Transmision : 5/6 - speed manual + get the low range dual from L series ?
- Differentials : lockable type - TBA ?
- Wheebase : XV : F: 2,635 mm, R: 2,644 mm
- Wheels : 17 x 7.0-inch 5-spoke aluminum-alloy. Dark gray with machine finish.
- Tires : 225/55 R17 95H all-season
- Spare : Full size, located under tray ?
- Fuel Tank : Relocate Forwards ? Bigger ?
- Length : XV : 4,414 mm
- Width : XV : 1,750 mm
- Height : XV: 1,570 mm
- Curb Weight: Approx 1,020 kg ( Roughly based on a XV & removal of unwanted bits )
- Colour: Plasma Green ...
Add : The overall length of tray would be short ? ( approx 1300 mm by my reconing ) ... So depending on your need, you could use the longer sedan version of the Imprezza body, which is apparently approx 100 mm longer, but its tail lights + rear end is different to the XV - or you can add a bit more to rear after the rear wheel arch, although other options of extending just behind the B pillar make it far more complicated ...

Anyone interested ?
Add : If you find one that has been rear ended + going cheap, then this may be a candidate for this mod ...
Edit's : Add more details + Second Sketch + add more - Feb 2014 ... Add Colour & Fuel Tank - April 2014 ...
