Cromwell was the fastest British tank to serve in the Second World War, with a top speed of . This speed was extremely beneficial in both attack and defence, outmanoeuvring opponents. At least one case is known of vehicle commanders using the vehicle's fast speed to jump large gaps. In the Netherlands, a troop of three Cromwells was able to leap a wide canal when surprised by enemy forces. This speed proved too much for even the Christie suspension and in later models the final drive ratio was changed to lower the top speed to , which was still fast for its time.
