Okay, I will try and make this simple and short. I have done 10+ years of electric car research, and am currently converting my first vehicle to electric, so might want to listen to my two-bits... ;)

-What do you want to use this thing for? (off-roading?, just cruising?), there is no way you will ever, ever, ever get near 200km range in something like that, unless you want to spend $12,000 on the battery alone...
To give you a realistic setup for awesome power and a range you can afford (practical costs considered), I personally use a brushed DC system of course (by leaps and bounds the best bang per buck, only option really) with about ~60hp peak, pushed by a ~100volt battery pack (I'll have to look into what brand/size of lead acid cells to go with). Just trying to guess on range, on a flat road (obviously not your intentions...), at 80kph (50mph) you should be consuming (and this is a very rough estimate) approximately 110Wh/mile... so, judging my the major limitations you have with this type of vehicle, you can fit 200 pounds of lead acid batteries on there, which should store 2700Wh (can only use 80% of it), so you are looking at 20 miles range... and this number only goes down when you are off-roading.
But i need to know alot more about what you want, specifically:
-1st, budget
-hp/acceleration times/top speed
-what kind of terrain are you running it on?
-how would you drive it? smooth runner? or a lead foot?
-would you want to step it up to lithium?
