When do you think the Honda Civic will get a new redesign?

My lease ends in 2022 and I see the 2019 Civic looks the same as the previous years except the change in hub caps, Honda sensing, and black chrome grill but other than that its pretty much the same car.

Will it look better in the future?

If the recent past is any indication of the future, Honda has been slow to fully re-design the Civic. They might do a minor cosmetic "refresh" between now and the next new Civic's release, but a full platform-redesign might not happen for 7+ years from when the platform initially debuted if history is any indication.

The current Civic platform debuted in 2016. I'd be surprised a Civic based on a new chassis/platform is released before 2022 or 2023 (at the earliest) if history is any indication. Before then I'd expect Honda to release a minor cosmetic update to keep the car looking "fresh" to people who know nothing about cars, but if you're looking for a Civic that is newer mechanically than your current Civic then it's going to probably be a 3-4 year wait.

In 2024 or 2025.
