The next full redesign of the Chevrolet Impala is currently not expected until the 2020 model year.
Unfortunately, we know close to nothing about what GM has planned for the next-generation of its full-size sedan. The car is currently expected to get a 9-speed automatic transmission for 2017 with minor updates to its exterior and interior.
We'll update this page as new information becomes available.
