The 22-year-old man injured in yesterday's fiery race track crash at Willowbank, west of Brisbane, is now fighting for his life in hospital after his condition worsened.

William Holzheimer crashed a high-powered Porsche club car into a wall on Champions Way at the Queensland Raceway.

The crash killed 26-year-old English professional racing car driver Sean Edwards, who was Holzheimer's driving instructor.

Holzheimer was trapped in the wreck for two hours before being taken to the Royal Brisbane Hospital in a serious condition.

The hospital says he is now in a critical condition.

Meanwhile tributes have come from around the world for Edwards.

Edwards was the son of racing driver Guy Edwards, who pulled badly burnt Austrian Formula One driver Niki Lauda from a fiery car wreck in Germany in 1976.

Edwards was leading in the Porsche Super Cup championship and recently won the Nurburgring Ring 24-hour event.

He last week travelled to Australia to coach drivers at the Queensland track.

Motorsport bodies and fellow drivers say Edwards was a great talent and his death is a huge loss to the sport.

Friend and fellow race driver Matt Halliday says Edwards had already achieved great success in motorsport.

"He is probably one of the most respected Porsche drivers in the world - huge talent.

"He went out on top. I mean you know, he's leading the Porsche Supercup championship.

"Nothing makes it easier but you know, when you see an athlete in the peak of his prime be taken down I think, you know a lot of people, it shocked a lot of people."

Former Australian world champion Alan Jones competed with Guy Edwards in the 1970s and 1980s.

"His dad, I think, would be even more upset if there is such a thing, with the fact that he wasn't in control of his own destiny," he said.

Jones says people should not blame the raceway or its management over the tragedy.

"You put a racing car on a racing track and if you hit something hard you're going to hurt yourself," he said.

Queensland Raceway CEO John Tetley says the track design did not contribute to a fatal crash yesterday.

He says their racing facilities are of a high standard.

"It's a piece of road, it doesn't do anything," he said.

"It's what people do on it that counts.

"It is the safest race track in Australia and this is in 14 years of operation, this is the first [car] crash we have had there that has resulted in a death."

In June, a 23-year-old motorbike racer died after he hit the back wheel of another motorbike and crashed.

The track is set to reopen on Friday.
