Campbell decided a massive jump in speed was called for following his successful 1964 land speed record attempt in ''Bluebird CN7''. His vision was of a supersonic rocket car with a potential maximum speed of {{Convert|840|mph|km/h|abbr=on}}. Norris Brothers were requested to undertake a design study. ''Bluebird Mach 1.1'' was a design for a rocket-powered supersonic land speed record car. Campbell chose a lucky date to hold a press conference at the Charing Cross Hotel on 7 July 1965 to announce his future record breaking plans:

{{Blockquote | style=font-size: 100%; | text="...&nbsp;In terms of speed on the Earth's surface, my next logical step must be to construct a Bluebird car that can reach Mach 1.1. The Americans are already making plans for such a vehicle and it would be tragic for the world image of British technology if we did not compete in this great contest and win. The nation whose technologies are first to seize the 'faster than sound' record on land will be the nation whose industry will be seen to leapfrog into the '70s or '80s. We can have the car on the track within three years."{{Citation needed|date=April 2015}}}}

''Bluebird Mach 1.1'' was to be rocket-powered. Ken Norris had calculated using rocket motors would result in a vehicle with very low frontal area, greater density, and lighter weight than if he were to employ a jet engine. ''Bluebird Mach 1.1'' would also be a relatively compact and simple design. Norris specified two off-the-shelf Bristol Siddeley BS.605 rocket engines. The 605 had been developed as a [[JATO|rocket-assisted take-off]] engine for military aircraft and was fuelled with kerosene, using hydrogen peroxide as the oxidiser. Each engine was rated at {{Convert|8000|lbf|kN|abbr=on}} thrust. In ''Bluebird Mach 1.1'' application, the combined {{Convert|16000|lbf|kN|abbr=on}} thrust would be equivalent of 36,000&nbsp;bhp (27,000&nbsp;kW; 36,000 PS) at {{Convert|840|mph|km/h|abbr=on}}.
