i would not be worried about fitting a kers and a 200l tank for several reasons:
- 200l is a very wide measure. With v8s you could look at considerably less (170 ?).
- a good base for comparaison is to take a pre-refueling era car (say 1992) running for instance a v12... this would volumetrically be quite similar to a v8+kers.
a good example hence could be the mp4-7 running a relatively voluminous Honda v12.

- Dont forget that by 2010, gen2 Kers will likely be a bit tighter and definitely more interesting.
Granted the regulations would probably push the driver back a bit for crash-test reasons but it really is not that bad. You can have a very tight package, not necessarly a super long wheelbase.
The car shown by isalmatron is the 1993 running a ford V8.. much more compact car overall.. but not THAT different.
