Sydney’s motorsport community is in mourning after a much-loved driver was killed in a high-speed crash at Eastern Creek on Saturday night.

Darren Barlow, 53, was a life member and the president of the Supersports Race Car Club of Australia, and a former national champion.

He was competing in the NSW Motor Race Championship on Saturday when his car left the track and rolled.

Paramedics rushed to the scene but he was unable to be saved.

“His vehicle left the racetrack at high speed and unfortunately rolled and he died as a result of that crash,” NSW Traffic and Highway Patrol assistant commander David Driver said.

“There will be a local investigation where the police will prepare a report for the coroner.”

In lead-up races Barlow’s vehicle, number 27, had ignition issues but no major incidents in the eight-car field.

Racing co-ordinator and close friend Ric Shaw said Barlow’s loss would be keenly felt.

“[He was] a lovely, friendly guy, he’d make you feel so welcome and so warm,” Shaw told 7NEWS.

“We’ve lost a guy who was worth his weight in gold and I honestly don’t know how you’re ever going to replace him.

“I’m sure everyone else in motorsport would want to say the same thing: I’d like to say Darren, thanks mate, and we’re really going to miss you.”
