"I’m really happy with how the livery turned out and I know our partners will be too... it’s certainly going to stand out on track," Mouzouris said.
"Hopefully, this year we can put on a better show with more racing on track, along with sponsor activities off the track.
"It was a tough off-season to get the funding together for 2021 but we made it, and I am even more determined to make a step forward this year.
"There were some positive learnings from last year and I know what I need to do this year to race at the front. I'd lastly like to give my thanks to Craig and Lara Lowndes for supporting me throughout last year and now moving forward into this year.
"Together with the Super2 team I'm looking forward to having a real crack.”
Feeney added: "To see ‘Feeney’ under the number 888 with Red Bull, Boost Mobile and Supercheap Auto as the sponsors is just surreal to me.
"I can't wait to see it hit the track and to finally share it with the public.
"Growing up as a kid in sport, you dream of one day being associated with Red Bull, so to have them on my car, suit and helmet is a dream come true for me and an opportunity that I look to capitalise on.
"To continue my partnership with Boost Mobile Australia is unreal.
"I've been working with Boost for nearly two years now, starting from a sticker on my helmet, to driving in the Bathurst 1000 and now to supporting my 2021 Super2 program.
"It has felt like forever after ending the season at Bathurst last year, but I have spent my time preparing the best way I can to return to Bathurst for the season opener.
"I have plenty of miles now at Bathurst and I can't wait to kick the season off. It has been four months waiting, but I'm ready to go racing now."
