Jokes from within Blood­hound’s en­gi­neer­ing team are that there’s an easy way, a hard way and then there is the Blood­hound way. But what will hap­pen at Hakskeen Pan in 2015? Will we see Richard No­ble and his team fail at the record at­tempt or will we see his­tory be­ing made?

Ac­cord­ing to Richard No­ble, they have mea­sured out a 20 km track with an ac­cel­er­a­tion dis­tance of 10.45 km. The car would thus reach top speed in roughly half the length of the track and would need to stop in less in or­der to leave some spare for pos­si­ble er­rors in cal­cu­la­tions. Ac­cel­er­at­ing to top speed in 10.45 km will re­quire an av­er­age ac­cel­er­a­tion of ap­prox­i­mately 1 g. With the car weigh­ing in at round 7.8 tons, an av­er­age force of 7.5 tons would be re­quired just for ac­cel­er­a­tion. In or­der to over­come the mas­sive drag to­wards the end, it would need some 20- plus tons of thrust.
