The model | T only had a starting, a cruising and a reverse gear. The same was true in the West Country in 1950 - there were some villages where many cars could not get out in first. However, my point was about applying that to getting uphill in slippery conditions. Think weight distribution calculations in O-level physics .... Regards, Nick Maclaren. |

The message
from (sarah) contains these words: We lived at the top of a hill just north of Edmonton. My mother (who learned to drive in England) regularly had to reverse her Mini up to our drive when the roads were icy, which was most of the winter; she told us it was standard practice in such circumstances. I think she kept a sack of sand or something to put in the boot in the winter to increase traction. Wow! A woman who can reverse! ducks and runs awaaaaayyy... -- Rusty Open the creaking gate to make a horrid.squeak, then lower the foobar. http://www.users.zetnet.co.uk/hi-fi/ |

It was a lower gear than the starting gear. The model T only had a starting, a cruising and a reverse gear. That's a good technique for front-wheel drive cars as well. Not because of the gearing (in general you want to aim to be in a higher gear), but because the weight of the car is mostly on the downhill axle and it gives you more traction. So you reverse up hills? Up steep hills covered in snow and ice(or loose gravel), when you can't get up forwards because the chains don't grip, it normally works. It's a bit scary though. Especially on autobahns :-) There aren't many Autobahns that steep. Luckily. On an empty mountain road with trees and cliffs on either side it's pretty worrying too. -- Tim C. |

The bit over the Schwäbisch Alb was dodgy but that's not half as bad since they built the tunnels some years ago. Anyway, it was rarely snowy as they spray an antifreeze mixture on the road at the top and let it run down the road. The roads have to be pretty steep to make the difference in weight on the axle significant. No m'way gradient will reach that. -- Tim C. |

Of course you always want to be in the highest gear possible for the situation; but these were situations in which first was too high to cope. I thought traction came into it in the sense that you wanted any extra traction over the driven wheels, whichever end of they car they were at, not dependent on the direction of travel -- but not so unbalanced as to imperil the steering.

I thought traction came into it in the sense that you wanted any extra traction over the driven wheels, whichever end of they car they were at, not dependent on the direction of travel -- but not so unbalanced as to imperil the steering. If you're going up a hill in a fwd car and the wheels are spinning you don't have much steering control. I hope it's clear that I'm only asking. This started from a topic about snowfall, not just steep hills. And my comments only apply to slippery roads. If the road has enough grip, and you can't get up then you want a lower gear. If you have enough power, but can't get the grip, the only way to improve that is to get more weight on the driven wheels. If you're going up a steep hill and there's not enough weight on the front wheels to steer, you're never going to get enough traction to drive up it either. That's the least of your problems. Contrary to popular belief rwd cars are normally better at getting up steep slippers slopes that fwd. If you're going up a steep hill in a car, a larger proportion of the weight will be carried by the rear axle. In a rwd car traction would be increased (in the same way as putting a sandbag into the boot). If you haven't enough traction to get up the hill then all you can do is add more weight over the rear axle. If the car is a front wheel drive, then the traction is reduced. To get more traction you increase the weight over the driven axle. You can do this by putting sandbags on the bonnet, or turning around and effectively turning the car into a rwd car. The actual gearing (either first, second or reverse) is less of a factor. Firstly you have to get traction, *then* you can worry about gearing. -- Tim C. |

In my mind's eye I see a single perfect snowflake drifting gently to the ground from a perfect pale grey sky. The driver of a car sees it and screeches to a halt, pointing. The car in the next lane stops, too, and before you know it the entire M1 is sitting gently in the lowering dusk. For no reason whatsoever :-) Sarah, you are poet rather than AA man, and the better for it. sorry AA woman. blush regards sarah -- Think of it as evolution in action. |

A sack of sand on the bonnet would have been even more effective Reversing up would have had a similar effect. We used to be allowed to ride on the bonnet (not allowed to grip the w/screen wipers, only the roof-gutter) for short relatively slow trips off-road, in Drumheller. In the summer. It was extremely good fun, but I can't imagine what any official at all would say about it today -- probably be speechless with rage and horror. regards sarah -- Think of it as evolution in action. |
