Let the cool, fresh air in and keep the interior heat out with these low profile window deflectors. WeatherTech Side Window Deflectors are designed with precision machinery and will be a perfect fit for your vehicle. Crafted in Germany, WeatherTech Deflectors are made of the highest quality 3mm lightly-tinted acrylic material available. WeatherTech Side Window Deflectors allow you to let in the fresh air and give you an OEM look. Nosecone stock a huge variety of different designs including side and top deflectors so their web site is well worth looking into.LED BULBS! - Quality HID Kits! - LED Dome Lights! - Car Mats! - K&N Filters - AND MUCH MUCH MORE!!! Unfortunately I do not have the benefit of before and after fuel consumtion figures to prove my theories but I have gained enough benefits to justify the effort and cost.
#Subaru forester forum side window deflectors plus
I got rid of my front window as I reckon 7 windows plus a skylight is too much in one living area. With a hinge at the top I can lift it up to create a canopy to hang washing out of the rain. An added benefit is if you hinge it as I did you get a storage cavity under which I stored my spare wheel plus sullage hoses and all extension cords, thereby removing clutter and hiding stuff from thieving fingers. I have fitted a Nosecone to the front of my caravan, as it was rebuilt with a square blunt front like a brick dunny so I had to do something to assist airflow. The Caravan test concluded that fuel saving was around 11% but stability and less turbulence was a welcome benefit. Granted this is also to generate lift, which we dont need when towing but also to allow the pressure wave in the front to slip off with minimum drag. An aircraft wing is blunt in front and tapers to a thin edge at the back. One study I read suggested the rear of a vehicle must taper down as per an aircraft wing to stop the negative pressure at the back which creates drag as you suck this air along as you drive. In reality you are simply increasing the frontal area by adding a deflector, and hence have to punch a bigger hole through the air. Most vans are too far away fron the tug to benefit from the deflectors ability to lift the air over the van. If you read the research that Caravan magazine did, in conjunction with Nosecone, they came to the conclusion that adding a cone to the front of the caravan closed up the gap between the tug and van as that is where the turbulence swirls and creates rocking motion. Like you I have often considered making a wind deflector and mount it on the carry bars of the Terry but if you dont get the correct angles it will probably cost you more in fuel than what it is worthĪny way I will continue to watch this thread to see what other members come up with You could also look at the possibilty of a nose cone on the front of the van especily if you have the type of van with no front window and even if it does have a front window I am sure you can speak to a fibre glass company to manufacture a nose cone I seem to remember a few old style of vans I think they were the Yorks and Viscounts that used to have a bulbous front end at the top it would have served a purpose maybe early style wind deflector or maybe just where the top cupboards were where as now most new style vans have slope back fronts. To be more aerodynamic they not only have to deflect the wind upwards but also outwards / sideways so as to try to reduce the drag along the side of the van and that's more difficult to achieve with a home made deflector I agree they were common years ago but they seem to have disappeared from the scene - the older deflectors were basically a piece of flat metal on an angle so were not very aerodynamic The article was the 1 where the car / van travelled in opposite directions I have thought about making and fitting a wind deflector for the car when towing the van because after I raised the height of the van suspension by about 5 inches / 125 mm the fuel consumption of the car increased by about 2 litres / H K so the thought was a deflector may help
