Quantum Sports Cars - H4

H4

By the time this model emerged, Harvey Wooldridge now considered this to be the fourth car he had designed, hence the name H4. The H4 was based on the Mark3 Fiesta and used what is often erroneously referred to as a 'surrey top' roof panel (which could be stored in the boot) and a rear section which could rotate into the bodywork to make a full convertible. At the beginning of development the curved glass for this rear section proved hard to source but eventually an Italian supplier was found. The H4 was produced from 1998 until 2003, when the Wooldridge brothers announced that they were looking to sell the rights to manufacture Quantum cars. As part of the sale, the H4's moulds were sold to an Iranian company. Rights to build the H4 outside the Middle East were retained but without the costly moulds it is unlikely that production will be resumed in the UK.
