Supercars rookie Jack Le Brocq's journey to the Supercheap Auto Bathurst 1000 included a retro road trip with a twist.

During the last leg of the journey from Sydney on Tuesday, Le Brocq took to the wheel of the Truck Assist 1946 Ford Jailbar for the cruise over the Blue Mountains.

The 72-year-old Jailbar recently underwent an eight-month restoration project, complete in a livery like Le Brocq’s Tekno Autosports Commodore Supercar.

Fitted with a modern drivetrain and safety features, it forms an integral part of the brand’s marketing drive.

“It’s awesome to be partnering with Truck Assist and to be able to bring a new sponsor to the sport,” said Le Brocq.

“The road trip is a lot of fun, the old Jailbar certainly turns a lot of heads, it’s something completely different to my Supercar, but it gets the job done nicely!

“It’s always exciting rolling in to Bathurst and seeing the big Mount Panorama sign up on the hill, that never grows old.

“This is our biggest week of the year, and I can’t wait to hit the track and see what we’ve got.”

Truck Assist, powered by NTI, is Australia’s leading truck roadside assistance and insurance provider, and teamed up with Tekno at Sandown last month.

Le Brocq is joined by 2016 Bathurst 1000 winner Jonathon Webb in Tekno's ZB.

The top rookie in the Supercars standings in 18th, Le Brocq himself has form on the board at Mount Panorama.

He took fourth in the 2016 Great Race with Cameron Waters in a Tickford Falcon, and second in last year's Dunlop Super2 Series 250km race.

Supercars take to the track for the opening Supercheap Auto Bathurst 1000 practice at 9:35am on Thursday.
