Ford Australia communications and public affairs director Wes Sherwood said Ford does not agree with the result, with internal tests showing the GT-F producing “pretty close” to 351kW at the rear wheels.
“We prefer not to go on the record with this (dyno result),” Mr Sherwood said.
Mr Pancione said his company has dyno-tested 30 HSV GTS models since the car’s launch last year, as well as “at least” 20 FPV GT models.
“The results (of the Wheels test) were right on the money,” he said.
“Good luck to them (Ford) if that’s what they think, but I can only deal with the facts and I’m confident the test we completed was correct.
“I’d love to have Ford come back out and we’ll test the car right in front of them.”
