This was the year the Impala wagon was initially killed off. Like Chevy had it before, the wagons took on their own name, in this case, Kingswood. This year also saw one of the most unique and rare options on any Chevy vehicle: the "liquid tire chain." The feature, which spraced traction-inducing and ice-melting juice onto the tires, was only available in this year and was hardly purchased. The unit sat in the trunk, one spray over each tire. Additionally, the ignition switched moved from the dash to the steering column and offered a new variable-ratio power steering unit. The horseshoe lights didn't last long, as Chevy re-introduced the three boxy lights at the sides of each rear.
