Read the heartwarming story behind this V8 Supercar's eye-catching new look for the Adelaide 500 race

Grace Lewis is only 10 years old, but she has made a spectacular contribution to the season-ending V8 Supercars Championship round in Adelaide, which starts on Thursday.

The final stanza of the competition will be staged in the City of Churches across four frenetic days - and remarkably, the youngster designed the official artwork that will appear on Pizza Hut Racing's Camaro vehicle.

Grace spent more than 15 hours working on her 'Super Pizza Car' sketch, and it was chosen ahead of a strong field to appear on driver Macauley Jones' Supercar for the Adelaide 500.

The design features a number of colourful red logo designs and shapes, with the window frames of the car hand-coloured with bright-red texta.

'I can't believe my design was chosen as the official artwork,' Grace said.

'I worked really hard on the design, and I can't wait to see it in real life at the race.

'My favourite driver is Macauley Jones, so I am over the moon he will be driving the car I designed!'

Jones was equally delighted for young Grace, who is a massive V8 fan.

'Watching Grace's drawing come to life on our car is super cool - it's just like if she drew it herself on the Pizza Hut Camaro,' he said.

'She's obviously a dedicated and passionate Supercars fan...it's awesome being able to have Grace's drawing on the car. 

'She should be so proud of what she's achieved.'

Simon Stocks, Pizza Hut's Director of Marketing, stated Grace's entry 'truly touched our hearts.'

'Her unwavering dedication, even while juggling school commitments, exemplifies the passion that fuels Supercars fans,' he said.

'It was a no-brainer for us to showcase her adorable work on our car, embodying our commitment to bringing Supercars fans and our customers closer together.'
