to keep the power on

21:31 Sep 21, 2008 

if you lift your foot (off the accelerator), you will get bogged in the mud and snow as you will allow the tyres time to sink in deep, where as if you keep the power on (the wheels turning at a good speed) you will pull across the top of the mud [Edit / delete]
1 hr
-> although it might be an idea to slow down for the bends!
To keep the power on is not to be confused with speeding :-)
Ie; when a F1 car spins out, "they keep the power on" to prevent it stalling. (keep the engine running)
