I have a r/c car that I'd like to use 8 of the 3.2v AA batteries instead of the typical 8 1.2v AA. There are two capacitors one is 2200uf 10v the other is 220uf 16v, if i replace them with 35v of the same capacitance will that work. Thank you
Will changing the capacitors for ones with higher voltage but same microfarad allow me to use higher voltage batteries

The voltage is the maximum the capacitor can withstand before the dielectric breaks down, and does not factor into the capacitance (measured in farads, \$F\$). Use a capacitor with the same capacitance, and the same or higher voltage rating.
Also, \$Q\$ is charge, and although it is the product of voltage and capacitance, you must use the applied voltage, not the rated.
The photo is helpful. I suspect it's a Chinese part that is numbered similarly to the Panasonic FP series.
That would make it a 220\$\mu\$F/50V 105°C RoHS low-impedance part, size code "G" (10mm⌀\$\times 10.2\$mm tall)
Of course if it's not a genuine Panasonic part (and I don't think it is, the markings don't look like the Panasonic parts I have) the characteristics may not be the same (and chances are they will be, at best, equal).

The simple answer is no. The whole system is engineered to use a particular supply voltage, there's no telling how many different things could go wrong if you overvoltage it by such a great degree (not just by 10% or 20%, by 160%!).
The less simple answer is that it would be possible. With some serious reverse engineering, know-how, and cash for quality parts, you might be able to safely overvoltage a cheap r/c car. Although, you would probably be better off just buying a better r/c car.
