Bloodhound LSR hit 628mph (1,010kph) in high-speed testing over the weekend, as fast as its current rocket will propel it.

The car left the start line in "max dry" mode – with no visible flames. At 50mph (80kph), driver Andy Green "put his foot down", pushing the jet engine into reheat or afterburner mode.
