We live in the mountains of western North Carolina, USA.
Our house is at the foot of a mountain and easily accessible.
Our neighbors are at the top of a rutted, dirt/gravel road that is quite steep and curvy.
Our front-engine, front-wheel-drive Honda Fit can make it up there, but
it is a bit of a challenge, with a fair amount of tire slipping.
I've also driven a 4wd truck up there, again, with a lot of slipping.
On a recently rainy day I drove our rear-engine, rear-wheel-drive Maeve up there and
she went right up with almost zero slipping.
I thought I might have to slow to a 1~2mph crawl to prevent slipping, but mostly was going 4~6MPH.
Reminded me of my old rear-engine/drive VW days, except the VW wasn't capable of
going super-slow on really steep roads - had to keep the engine RPMs up.
The pulling action of FWD has the advantage in snow, but
if I had to choose one or the other, it would be Maeve for year-round usefulness.
Thanks and good health, Weogo
