The Pierce Impel and Pierce Velocity are custom fire apparatus chassis built by Pierce Manufacturing, and were introduced in 2006.

Production[]

The Impel and Velocity are designed with identical structures and share many of the same features but the Impel is built as a medium-duty chassis, whereas the Velocity is built as a heavy-duty chassis. The early models of the Velocity & Impel were known for their large, protruding front mirrors (nicknamed 'bus mirrors', due to their resemblance to some school buses). Eventually, Pierce also began offering more conventional-style mirrors.

In the early 2010s, Pierce redesigned the raised roof of the Impel and Velocity with a new "forward roof" design. This allowed for additional headroom inside the cab.
