The reason the 9volt won't work is it's current limited. Yes it's got more volts but it can't deliver the amps needed to make power (watts). Look at a batteries mAh rating. The higher that number the faster your car will be. Example; 9volts but only 400mAh vs 6volts with 800mAh; 9*400 = 3600 while 6*800 = 4800
The NiCads have the lowest energy density (they suck) while the NiMH and lithion ion are high (reasons they're in newer electronics). I'd get some NiMH AA's with really high mAh ratings.
