Ranger Posted April 5, 2006 Share Posted April 5, 2006 Hi Chain Gang, an old motor homing mate of mine lives up a very steep hill in Briton Ferry, average tarmac surface, but on a wet day F.W.D.s just will not go up, he got fed up with having to reverse his F.W.D.motor home up it on wet days so has gone back to rear wheel drives. It is OK for him he can afford Mercs. I'm not knocking all F.W.Ds, I had a mini when I was working, with chains on the front wheels no snow ever stopped it, but the wife had a Wolseley 1885 S, same idea as the Mini but twice the size and weight, it was hopeless, as far as traction was concerned, even got front wheel spin taking off from traffic lights on a good dry road.

enodreven Posted April 12, 2006 Share Posted April 12, 2006 Hi, I know they use 4WD and FWD for rally cars but i don't think i have heard of any one using a RWD rally car for more years than i care to remember ?? anyone know WHY ?? I have also been told that there is a problem with RWD motorhomes and the floor heights ? i don't know if this is a problem or not ? Oh i drive a RWD mercedes C220 CDI auto estate with ABS ASR etc, and the hand book tells me to turn off the ASR ? when on snow or ice ? i though that was when they were most needed ?

Ranger Posted April 13, 2006 Share Posted April 13, 2006 Hello Enodreven, I expect most rally cars are FWD because most cars are built that way these days, the only RWD seem to be expensive ones like Mercs BMWs & Volvos etc. It is of course a lot cheaper to build FWDs the complete unit goes in as one lump on the production line instead of having to join up the drive to the back axle. In general FWDs do not make good tow cars, with a few exceptions like Citroens, but they have been building FWDs since goodness knows when. I wonder how a rally driver would get on with a motor home??? Link to comment Share on other sites More sharing options...
David Dwight Posted April 13, 2006 Share Posted April 13, 2006 Hi Ranger. Yes citreon's make good tow cars. We changed from a Volvo 245 to a Citreon BX for towing the Citreon won hands down. As to you other query yes Ex rally drivers do drive M Homes a bit hairy on some of the Forest sections though. David Link to comment Share on other sites More sharing options...
colin Posted April 13, 2006 Share Posted April 13, 2006 Most formula 1 drivers seem to have motorhomes I wonder what their lap times are? Link to comment Share on other sites More sharing options...
Yorkshire Tyke Posted April 13, 2006 Share Posted April 13, 2006 Hi the problem with floor heights on RWD MHomes is that you require space for the drive shaft and Diff. that means that the floor HAS to be higher than RWD; where the rear wheels just realy serve to stop the rear end scrapeing on the ground Link to comment Share on other sites More sharing options...
Clive Posted April 17, 2006 Share Posted April 17, 2006 I thought most rally cars are now 4X4 with special limited slip diffs, variable ratio whatsists odd percentage front / back power split etc?? C. Link to comment Share on other sites More sharing options...
colin Posted April 18, 2006 Share Posted April 18, 2006 Not sure what the situation is this year as rallying is almost as bad as F1 for rule changes, but couple of years ago 4x4 teams where complaining because rules ment FWD cars had a massive advantage on tarmac stages.
