 Phase 2 has started with further rocket motors and propellants being tested and the a smaller version of the selected engine design being constructed.Once this has passed the testing phase, then work will start on the full size motor (62,000 lb/f - 200,000hp).This should propel the car from 0 - 1000mph in around 20 seconds, burning about 3 tonnes of propellant over the full 1,000mph run.
