There’s a lot to love about sedans — sleek, sexy, and easier to drive (and park) than their larger SUV and truck brethren. These days, there are sedans for every kind of driver. You can admire the fastest sedans ever made, or sedans with high ground clearance, or even luxury sedans known for fuel efficiency. But one thing most sedans lack? A rear windshield wiper.

Although there is no single reason why sedan manufacturers seldom include rear windshield wipers, a few factors may have something to do with it. First, removing the rear wipers saves car makers money without affecting compliance, because U.S. law does not require them for sedans. 

Secondly, rear windshield wipers can affect a car’s appearance and overall drag coefficient, which can make it less appealing to some drivers. Hyundai told Motor Trend in 2023 that it initially didn’t include a rear windshield wiperon its electric SUV, the Ioniq 5, for two reasons: aesthetic preferences and airflow performance.

Lastly, sedans have tapered rear ends and sloped rooflines for improved aerodynamics (and, therefore, fuel economy), which can eliminate the need for a rear wiper. A sedan’s airflow passes across its rear window while it’s in motion, which can help remove water or light dirt particles that may have been trapped there when the car was standing still.

However, not everyone is convinced that rear wipers are unnecessary. Here’s why.

In an ideal world, the design of the modern sedan should be more than enough to keep your rear window clear. However, there are some cases where drivers may need a little extra help. For example, if you’re stuck in traffic in the middle of a heavy rain shower, your car may not move fast enough to clear out the water. And heavier particles, such as snow, may not come off as easily with just air. So rear windshield wipers can be useful if you live in an area that regularly experiences heavy snow.

In fact, there’s no hard-and-fast rule for not adding a rear windshield wiper on sedans. Škoda, a Czech automaker owned by Volkswagen, told Jalopnik it offers rear wipers as a free option for its Superb models. The catch is that the Škoda Superb is on our list of handsome sedans that are forbidden fruit – that is, unavailable – in the United States.

But there’s still another advantage to not having a rear windshield wiper. You’ll have one less thing in your car to repair — and your car is less likely to be recalled due to windshield wiper issues, like the Tesla Cybertruck.
