The British engineers behind the latest land speed record challenge believe they have found a solution to the aerodynamic issues created by attempting a 1000mph record.
The team behind Bloodhound SSC believes it has cured the dangerous amount of lift produced by initial models, and created a design that enables the car to remain flat on the ground at a scarcely believable Mach 1.3.
The new configuration has been heralded as a major breakthrough as the team behind Thrust SSC fight to better the 763mph world record they set in 1997.
"At Mach 1.3, we've close to zero lift which is where we wanted to be," said John Piper, Bloodhound's technical director.
"Up until this point, we've had some big issues. We've had lift as high as 12 tonnes, and when you consider the car is six-and-a-half tonnes at its heaviest - that amount of lift is enough to make the car fly," he told BBC news.
Managing the shockwave that will be produced when the car goes supersonic proved to be difficult, but the team's modelling efforts were boosted by sponsor Intel.
Using their computer processing muscle, Bloodhound's engineers were able to increase the pace of their work, and reshape the car's rear end to provide stability at the 1000mph target speed.
Bloodhound SSC is powered by a jet engine from a Eurofighter plane and a hybrid rocket. The team hopes to mount its challenge on a dried up lakebed in South Africa late next year.
