The Smart Wiper System is what has always been on the Clarity. This Honda
sales training site explains the Smart Wiper System thusly:
What’s the Benefit?
This system enhances the driver’s visibility during washer operation while using less fluid to clean the windshield.
The Feature:
The Clarity features a remarkable windshield wiper/washer system.
- The washer nozzles are mounted on either side of the wiper arms, rather than at the base of the windshield as in normal systems.
- When the driver initiates the washer, the nozzles only spray in the direction the wiper blade is moving.
I wish there was a button to pump some more of that tiny bottle of washer fluid onto the windshield. I can't seem to get enough on the windshield to stop streaking.
Like you, I cannot detect any difference between the 2018 Clarity Plug-In Hybrid and the 2019 model shown on Honda's Clarity page. So the only information left to discover is when the same car will start showing up with a 2019 serial number. Perhaps the Service Bulletin updates will come pre-installed in the 2019 models?
