Ed Ordynski, an Australian Rally Championship winner, gave evidence on Wednesday at the inquest into the death of Launceston-born John Ernest Mansell.

Mr Ordynski has sat on commissions of enquiry into race fatalities and prepared a report for the inquest.

Mr Mansell died at the scene on April 17, 2013, near Exton, when he drove over a crest at 200km/h, became airborne, landed heavily, veered off the road and hit a tree.

His navigator Tristan Catford was seriously injured.

On the third day of the Launceston inquest, graphic in-car footage of the crash was played in court during Mr Ordynski's evidence.

Barrister Ken Stanton, for the Confederation of Australian Motor Sport, asked Mr Ordynski if the speed of Mr Mansell's car, 200.5km/h, surprised him.

"You would not expect a competitor like John Mansell to be doing 200.5km/h over that crest?" he asked the witness.

"It surprised me for two reasons," Mr Ordynski replied.

But he said he was not surprised that Mr Mansell would reach that speed during the event.

Mr Stanton asked Mr Ordynski if he was surprised because the competitor who won the event had actually gone at a slower speed at that point.

The witness said that was correct, but he had found that out by looking at the data.

"There is no obvious need to press in that stage?" Mr Stanton asked later.

"Yes that's correct," Mr Ordynski said.

The inquest, before coroner Simon Cooper, continues.
