I was wondering.. what are the best ESC's for 10s?

I'm really looking forward to the new HV CC ESC, but I was wondering, what kind of current ESCS support 10s for cars?

I've seen very cheap heli/plane escs used for 10s in cars, but how much know how does this actually require? Do you need to modify the ESC itself?

Any info on 8s+ escs and how to use em in cars would be greatly appreciated! :)
