Nathan Herne was at the gym when he got the phone call he had waited his whole life for — a call-up to drive a Lamborghini around one of the world's most famous circuits.

A week later and the northern New South Wales driver is now en route to Belgium to compete in the Lamborghini Super Trofeo Europe series around Circuit de Spa-Francorchamps.

The Super Trofeo Europe serves as a supporter series to the World Endurance Championship which holds the Six Hours of Spa this weekend.

"Lucky for me one of their drivers had to pull out due to family commitments, so that opened the door for me," the 21-year-old said.

"It's going to be a pretty cool time."

It is a dream job for someone who has spent almost their entire life behind the wheel.

Herne started out at the age of five racing go carts in his home town of Lismore, progressing through a long association with Formula Ford and on to driving muscle cars in Australia and the Trans Am Series in America. 

More recently he has been leaving  the helmet at home to work track side with the Trans Am and TA2 cars in Australia.

This week he will be reaching speeds of up to 300 kilometres per hour in a 650-horsepower Lamborghini V10 around the track at Spa.

"It's been a dream of mine since I was a little kid to race in the GT Series," Herne said.

"They are serious cars over there.

"As an Australian and especially from Lismore, you really don't have an opportunity to race [at that level]."

"It's just going to be a really cool experience."

Herne will have less than two hours once he gets in the car to run through his paces at the Spa-Francorchamps circuit.

He said this was not ideal, particularly as his track simulator blew up when he tried to load it after getting the call from Lamborghini.

"It's not a lot of time considering I have to learn both the car and track combination," he said.

"When you don't know the car and you don't know the track it's borderline insanity to try to go fast, but I've got a really good team with me who have sent me a lot of data and footage to research.

"It's very easy to go to a track and know what to expect nowadays."

Herne's father, Stuart Herne, said the call-up was a great achievement.

"I believe that the more you put into things, the bigger the reward, and Nathan has certainly put a lot into racing," Mr Herne said.
