Its all about rolling resistance, momentum, and wind resistance. Tall narrow tires, a long skinny body, and a low Cg (either through weight, or by using aero to achieve it). Look at land speed record vehicles. They are NOT shaped like a lemans car (ie., glorified ferrari/mclaren/etc). Jet bodies are another example. Long, round, and narrow.
If you could get into the programming, you'd want to use as little of your available juice as possible to get up to a certain speed, then crank it up for the high speed burst. Maybe gearing it so that it'll barely get out of its own way to start - as long as you can up to speed and shut down prior to thermalling........heck you might be able to do this without spending much. Maybe spending the money on some custom wheels and a build your chassis based on those land speed vehicles....now I've talked myself into possibly trying one of these!
