Do ditch lights lower MPGs?

So I had a 1988 BMW 325iX, in European markets, some of these cars (316i) only came with a drivers side mirror and had a blank plate on the passenger side. Since there was both left and right hand drive variants, there were blank plates for both sides.

I ordered 2 plates and replace both my mirrors with blank plates. My mpg went up by 3mpg because of it. Its pretty amazing how much drag parts sticking out from the body can actually cause.

Not a shit post, I actually did see a pretty big increase in mpg.

 

I don't even have a set of ditch lights. But now I want them.

 

But was that 3mpg on 40mpg, or 3 mpg on 6mpg? Ratios matter.

 

3mpg on 17mpg. Then it all went to shit when I lifted the car, put a roof rack, oversized tires and a snorkel.

 

Soon, the 4th gen forum will be flooded with these type of threads. Lol

 

I turned my ditch lights around so they face backwards. When I turn them on I can take advantage of photonic thrust, much like the NASA light sails for interstellar travel.

The hard part is driving at night with them because boy howdy does Baja Designs make a quality product!

 

Yeah, but the Dakar Rally vibes are forever!

 

Before the snorkel. You didn't mention the rack lights. of course that would make it worse.

 

Highly educational ones, you mean?

 

Ok, I can wrap my head around that!


Someone stole my tailgate, so I will now have better mpgs, right?

 

Autobahn designed cars are better.

My '82 Golf GTI 1.6l (Heron head) has no passenger-side side-view mirror, there is a cover on the mounting hole and came stock from the factory in Hannover with the highly desirable A pillar fairings.

 

My buddy just installed a new bumper last night on his Bronco and installed some BD S2 Pros as reverse lights... he thinks they are overkill. I'll have to give him this info about it helping his MPG.

 

Anything that reduces aerodynamics reduces MPG. Ditch lights probably wouldn’t have a huge effect, but it’s also probably a nonzero effect.

 

My hood ornament really killed the mpg on the car....

Copper plated seagull skull

 

Weight also reduces MPG, no matter how small.

 

Shoulda left the feathers

 

BD do make led light thrusters, but not Tacoma rated.

 

Does it whistle?
