I'm checking!!

Sorry Dad

You can come out if you promise to be a good boy.

the mud flaps are to small to stop the spray up the back window, but have read this on anther forum and may give it a try.

I paid £12.00 for some polypropylene sheet and fitted them myself, easy peasy, mine are now 3" longer and keep the rear window clear

I'm surprised. I've got larger 'Rally' style mudflaps pop-riveted onto OE mudflaps and I still get spray onto the rear window and have to use the rear wiper. Maybe my currently fitted winter tyres don't help.

Yesterday evening I was in the unusual circumstance of being on the Motorway near home, no rain but the road was completely sodden from a recent heavy shower and there were no other vehicles either behind or in front of me. Driving at ?? mph it was amazing to see the plume of spray following me with, about 10 car lengths behind, the edges being wrapped inwards into vortices.

Talking of rain, opted not to try get through a flooded road this afternoon; think the Yeti would have made it no problem, however I thought better of it after remembering what happened to rockhopper and took a longer route home via a small detour (see below).

Oh did give a lift to a lady who had tried to drive through in a Peugeot 206 van but lost the engine half way across. Some people had push her back out but then left her by the side of the road and drove off.

I'll try

System at work has allowed me a little "play".

One of the spoilers in question:

They do a couple of other very similar ones.

Your description of the squared tail is the Kahm Effect.

Graham, is this a signal that you train-ed in aerodynamics?

Well. This is weird - the 3 times I've driven in rain so far in the Yeti have left me looking in the rear view mirror thinking how odd it was that I still didn't need to cycle the wipers. Compared to my Subaru anyway, which needed it left on intermittent most of the time. And it had a spoiler.

Coincidentally, the 3 times I've driven in the rain I also had 2 bikes loaded onto my towbar mount carrier. And I also remember being surprised at how dry the bikes were.

So completely converse to what was said earlier, I (probably incorrectly) formed the opinion that the straight back was actually better for keeping rain off the rear glass, and protecting items in the car's wake. I'm sure I'm wrong ... and I have zero aerodynamics knowledge to speak of ... but that's just how it was for me.

I can see some rain heading my way on the radar, and I have to head to the shops this arvo ... so I'll be keep to see whether it was a one-off thing or perhaps just the wind direction those days.

Oh, I have stock mudflaps.

I find speed is an influencing factor i.e. pottering around town there is little spray to the rear window but at higher speeds, on the Motorway, there is shed loads of it (or should that be buckets?)

For comparison my wife's Roomster is afflicted with the same issue but my previous Octavia never had a drop of spay on the rear window, it seemed that the airflow remained 'attached' to the roof & rear window to sweep/blow it off.

I'm surprised. I've got larger 'Rally' style mudflaps pop-riveted onto OE mudflaps and I still get spray onto the rear window and have to use the rear wiper.

Are they made with a smooth surface that will break the water into a fine spray when it hits it (and make matters worse) or like the 'astro turf' ones fitted to lorries that are designed to stop the water turning into spray?

Interesting and very valid point. The former.

They are made from heavy duty 4mm flexible plastic, MSA approved/required for rallying; more designed to stop stones than spray.

I did investigate using the 'astro turf' type SprayGuard material that is a legal requirement for trucks these days but decided that, on a little ol' Yeti, it was a bit of overkill apart from being quite bulky, heavy and costly.

That's spooky - I was just thinking that since I got the car in February, the three times I've driven it in the dry, I was surprised how dusty the car got

"Driven it three times in the dry" ... yup, sounds about right for Ireland

I'm watching this with interest. Betty's botty does get messy and requires the wiper on almost all the time, so anything that can be done to reduce this the better.

It was the same on a previous Vectra Estate, a Zafira hire car and to some extent a Corrolla T-Sport hatch a had 10 years ago.

The worst was the Zafira with the Yeti a close 2nd with the Vectra. I've always put it down to a vertical rear end!

The bloke who fitted the spoiler (or whatever name you want to give it) hasn't been on to tell us if it works though.

As Bahnstormer said, around town it is not too bad, but over 30mph and I need to start using the rear wiper. The back of my car is plastered at the moment after the last few days.

TP, as for going through water, as long as it isn't deep enough to go over the bonnet, you might be ok

fording depth should be about 180mm officially I seem to remember - the bottom of the sills, but I have been though much deeper.

you may have seen this:

and this:

PS neither of those was the deep water one , just muddy.

Thanks Mike,

just me chickening out but I felt happier driving round as I had the option.

Been through deep water before in an old Astra TDI van which struggled to make headway in first gear (water level was well over the sill). Nearly lost the motor due to a large 4x4 coming through the other way putting a bow wave over both the bonnet and roof

Hi team,

Try Yeti ownership in Australia where road builders put zero thought into the possibility that it might rain! Honestly I think sometimes the rear window gets wetter than the front in the wet. It is as discussed an aerodynamic issue which made me have 2 thoughts. If you go fast enough can you outrun it and use it as a valid excuse to the policeman that you were just trying to maintain good visibility in all directions :-) and 2, do rear venturi spoilers reduce the effect just as you get on high performance super cars and the new Kia Cerato Hatch? It would make for an interesting look on a Yeti!

How about the rear diffuser?

Personally not a fan of the look, but would it solve the problem?

Don't really understand what the problems are with you guys in the South and rain - I thought you were all on hose pipe bans cos you haven't got any rain!

Its not stopped raining since they banned us from using the bl--dy hose pipe

Nothing to do with the actual rain as such, it's how much is being retained in water sources such as the South Downs aquifer balanced against demand.

Unfortunately our politicians just don't get that population expansion and subsequent house building etc. combined with a warming climate will eventually be far beyond natures limits of provision. The only real answer in not an Indian rain dance but Government finding fair ways or discouraging all forms of population expansion but thats one very hot potato to deal with and it would take a much braver politician than those we have now to take on that mantle.

+1 they are thinking of building 1000 houses around this area without any thought to the over stretched demand on a few old water supply systems

I don't believe you! You have a drought but complain when it rains!

Well so long as water is privatised you don't expect them to give up profits to give you water do you?
