Why hatchback has rear wiper one?
-
Hatchback .. you know .. those cars with no backside.
I've seen many with rear wipers. How come?
Other than Evo, which sedan has rear wiper? -
Peugeot 406.
My guess is that the steepness of the rear windshield affects visibility in the wet somehow... -
Actually that question is still under heavy scrutiny.
The cheapest hatchbacks have rear wipers, but the most expensive saloons don't. As for which other sedan that has rear wipers, i think the lexus LS400 as one. -
People say hatchback more susceptible to rear splash.

sounds logical.Originally posted by ditzy:People say hatchback more susceptible to rear splash.
I hope Porsche has rear wiper too .. 'cos her backside is quite thin. -
Ahh yes! Rooster tails!Originally posted by ditzy:People say hatchback more susceptible to rear splash. -

more susceptible to rear splash but still the incline is greater right? so water should flow down faster and the aerodynamics will help?
what is rooster tail? -
I still cannot figure out how come the evo has a rear wiper.
does the evo rally car have rear wiper? how about the subaru wrx rally version? -
The spray kicked up behind the car as it moves forward in wet conditions. The sedan's boot stops it from reaching the rear windscreen.Originally posted by Icemoon:what is rooster tail? -
It's not necessary, actually.Originally posted by Icemoon:I still cannot figure out how come the evo has a rear wiper.

When I was young, I actually thought the air travelling over the vehicle as it sped will blow it strong and rough. So I attached a balloon with a string and tied it to the rear window of the van. The van moved faster and faster, but the balloon didn't move a fcuking bit.Originally posted by Icemoon:I thought for a moment . .suddenly don't sound logical liao.

If your car has a backside and another vehicle rear ended you - everything ok. Just a lot of hassles fixing the rear damage.
In hatchback, no backside means other vehicles occupants splatter their brains and blood on your rear windscreen, so must have wiper so you can see clearly to report to police the licence number of vehicle that damaged you.
That is why hatchbacks have wipers.
If you drive expensive vehicles without wipers, why you worry about an accident?
Throw enough money at a problem and the problem goes away ...... -
Cos the engineers felt like putting one on it?Originally posted by Icemoon:I still cannot figure out how come the evo has a rear wiper.

Theres a theory for this..
That the way the windscreen is positioned and due lack of a boot.. dust and mud tends to cumulate more on the rear wind screen than a car with a boot. Thus a wiper is necessary.. -
hmm .. I thought if you wipe a dry wind screen, the wiper will spoil very fast?Originally posted by LRRP:Theres a theory for this..

the rear wind screen can shoot out water or not?

Depends on whether it comes it a washer jet that allows it to do so.Originally posted by Icemoon:the rear wind screen can shoot out water or not? -
well.. my logical explaination is that...
HB cars rear windscreen is more tilted.. the wind resistance from the front cutting through the car will not come into contact or hardly come into contact with the water droplets.. so when driving in the rain, visibility is poorer because the water will not be pushed away.. hence, a wiper is needed to clear the water..
on the other hand.. sedan's rear windscreen is more towards "horizontal". i believe since of the angle difference, the wind resistance coming from the front have more chance to come into contact with the droplets at the rear end.. pushing away water.. therefore no wiper is needed..
i may be wrong.. but seems logical to me though.. -
why ah? simple analogy can answer it ever cycled on a wet or muddy path without a rear mud guard over the rearwheel? ever notice the nice mud splatters on yr shirt after that?
