Have you ever hopped into your Cybertruck, admired the perfectly straight wiper, and then hit highway speeds—only to notice it shift slightly to the side? Did you wonder if it was loose or even considered reaching out to Tesla Service for a potential motor replacement?
Turns out that it’s not loose at all. In fact, it’s yet another clever aerodynamic trick the Cybertruck employs at higher speeds to boost efficiency. Let’s take a closer look at how it works.
Aero Mode Wiper
Matt Wallace over on X spoke to Wes Morril - Tesla’s Cybertruck Lead Engineer - who revealed some clever engineering Tesla built into the Cybertruck’s massive wiper. At higher speeds - roughly around 45 mph (75 km/h), the Cybertruck will move its wiper about an inch or two inwards. This movement inward optimizes the aerodynamic profile of the trick.
While Wes didn’t mention just how much of an efficiency boost it provides - we image it to be in the range of 1-2% - not negligible, but not much either. However, when traveling longer distances at highway speeds, that 1-2% can add up quickly.
If you’re going 500 miles, that adds up to an additional 5-10 miles. While it doesn’t seem like a lot, imagine that stretched across an average year of driving - 15,000 mi. That’s an annual savings of anywhere from 150 mi to 300 mi, which is pretty much an entire charging stop.
Wiper Down
Here’s another feature that non-Cybertruck owners may not have known. The Cybertruck’s massive wiper actually stays down after wiping some times to ensure that the water that’s been pushed down gets pushed away from the windshield and doesn’t come back up. This is generally done when the wiper is either on Auto, or at a low intermittent speed.
From personal experience, this little technique does a fantastic job of ensuring that the windshield remains clear, but just like the Aero Mode, it can be a little bit odd seeing the wiper down until you understand why.
Cybertruck has plenty of unique tricks up its stainless steel sleeves, and we’re excited to hear about more of them as they’re uncovered. However, Tesla, we would love it if you put some of these tips and tricks into the Owner’s Manual. It would save a lot of hassle and prevent vehicle owners from putting undue stress on the already hard-working Service Centers.
