That “weird gap” referring to is a feature found in many modern cars, usually located between the two primary cup holders in the center console. While it might look like a design flaw, a coin slot, or a place where a third cup holder used to be, it is actually a highly practical piece of engineering.
It is most commonly known as a “Cup Holder Pass-Through” or a “Purse/Phone Slot.”
Here is exactly what it is for:
1. Feeding a Charging Cable (The Main Purpose)
The primary reason automakers design this gap is to allow a charging cable to pass through from the storage compartment under the center console armrest (where the USB or 12V ports often live) up to your phone, which is sitting in the cup holder or a dashboard mount.
Without this slot, you would have to leave the armrest lid open to run a cable out, or you would have to pinch the cable under the closed lid—which can damage the wire over time. The gap allows you to keep the center console closed, looking tidy, while your phone charges safely.
2. Preventing Cup “Sweat” and Spills
If you put a cold drink in a cup holder, condensation forms on the outside of the cup. If the cup holders are completely sealed off from one another, that moisture has nowhere to go and will pool at the bottom, making your cups slippery and dirty. The gap allows for ventilation and evaporation. It also makes the cup holders significantly easier to clean, as crumbs and drips can be swept directly out through the slot.
3. Accommodating Travel Mugs with Handles
Many large reusable travel mugs or coffee cups have handles. If the two cup holders are placed too close together with a solid plastic wall between them, the handle of one mug might block you from placing a cup in the adjacent holder. The “weird gap” provides the clearance needed to fit bulky mugs side-by-side.
4. Holding Flat Items Securely
While not its primary intention, the slot is perfectly sized to wedge in flat, narrow items so they don’t slide around the car while you drive. It is a very convenient place to store:
-
Your phone standing upright.
-
A key card for a parking garage or hotel.
-
Sunglasses (folded).
-
Cash or coins.
Summary:
It is not a mistake or a missing feature. It’s a smart, minimalist design choice by car manufacturers to let you route charging cables neatly, allow for easier cleaning, and create a flexible storage nook for flat items.
