Respectfully, I'd consider another option before you jump straight to standard mud flaps. I've been tinkering with EVs since the early Tesla days, and honestly, the aero hit you take with bulky guards is real—you'll see your Wh/mi creep up and your range dip, especially in winter when the battery is already struggling.

I'd actually suggest going with a 'less is more' approach. Instead of the massive OEM ones, I’ve had way better luck with A-Premium Splash Guards for Mercedes-Benz EQB250 EQB300 EQB350. They’re technically a 'no-drill' design that uses the existing factory wheel well liner screws. I installed these on a friend's 350 last month and the fitment against the cladding was surprisingly tight for aftermarket stuff.

But here’s the pro tip: if you’re really worried about that 'sleek EV aesthetic' and paint chips, combine the flaps with a DIY strip of 3M Scotchgard Paint Protection Film Pro Series. I always apply a 4-inch strip right behind the wheel arches before putting the flaps on. It prevents the grit that gets trapped behind the plastic from vibrating and scratching your clear coat over time. Basically, it’s double the protection without looking like you’re driving a rally car. Plus, the A-Premium ones are way cheaper than the Mercedes dealership markup, so it’s a win-win imo. Just my two cents after dealing with salty winters for a decade!! 👍

So, before you dive into buying anything, it is worth knowing that the EQB has a pretty unique aero profile compared to gas SUVs. Basically, EVs are designed to be super slippery in the wind, but those wide tires are essentially debris magnets. Because there is no engine noise, you actually hear every single pebble hitting the wheel well... it is so loud lol.

Protecting that paint is HUGE though, especially with winter coming. Honestly, I noticed the same thing as you—road salt and gravel literally peppering the side panels after just a week of driving. It is not just about keeping it clean; it is about avoiding those tiny chips that ruin the *amazing* look of the car and kill your resale value later. Plus, the salt they use on the roads can be brutal on the lower trim if it just sits there.

I was in the exact same boat, torn between the official Mercedes ones and something cheaper. For my current setup, I ended up going with a reputable aftermarket set that was marketed as a "no-drill" fit. I was super worried they would look tacky, but honestly? They look great. They used the existing plastic rivets already in the wheel arches, so I didnt have to poke any new holes in my brand new car! It took me maybe 20 minutes per side to install. Lowkey, I saved a ton of money compared to the dealer price, and the durability has been fantastic. They dont look bulky at all, they kinda just blend into the black trim. If you find a set that uses factory holes, definitely go that route. gl! 👍

Big if true

I totally agree with the point about the range hit if you go too big, i noticed a small drop in efficiency when I tried some generic ones earlier this year so definitely stick to the smaller profiles. As someone who likes to do things myself but is always a bit paranoid about breaking those fragile plastic clips on a new Mercedes, I found that taking the DIY route is the way to go if you want it done right without overpaying at the dealership. I ended up looking at Gledring Custom Fit Mud Flaps because they seem to have that perfect balance between being subtle and actually stopping the slush from hitting the doors. If you are going to install them yourself, here is what I learned from my trial and error:

• Use a proper plastic pry tool for the wheel well rivets so you dont gouge the trim
• Clean the mounting surface really well with some rubbing alcohol because dirt trapped behind the flap will eventually sand down your paint
• If the kit comes with those little metal U-clips, just be careful not to overtighten them or they can crack the plastic liner Honestly I was pretty nervous about it but it only took me about forty five minutes for all four wheels, you just have to be patient and maybe have a flashlight handy to see into the dark arches right? It is definitely a job you can handle if you have basic tools lying around and it saves a ton of money over the OEM ones!!!

Regarding what #5 said about "I totally agree with the point about the..." - i definitely think its a valid concern, though in my experience the paint protection usually outweighs a minor efficiency loss if you pick a low-profile design. Over the years, Ive tried many different setups and the DIY install is almost always the way to go if you want to ensure those plastic clips dont get mangled by some shop tech. Before i give you my full recommendation, i have a quick question. Are you looking for a completely toolless install, or are you comfortable using a stubby screwdriver and working inside the wheel well? If you want the cleanest look, honestly just go with something from WeatherTech. You really cant go wrong with their stuff for a Mercedes because the fitment is basically factory-level without the OEM price tag. TL;DR: Stick to laser-measured brands for a clean DIY job that wont kill your range.

Great info, saved!
