"We managed to go from one step to another and grow our team from 35 staff back in 2009 to almost 70 staff now.''
Kelly said that it was critical to have factory backing, something history has proved and something which has been demonstrated this year with the domination of factory-backed Holdens and Commodores in the V8 Supercar championship.
However that fact also throws a shadow over the planned Erebus Mercedes Benz entry next year which will have the backing of Mercedes' AMG performance arm, but not the factory as a whole.
The next and most practical challenge for the Kelly Racing Altimas - resplendent in black and red, with bulging wheel arches and steeply sloping windscreens - will be testing the car and experimenting with a vast "toolbox'' of aerodynamic add-ons.
Todd Kelly said the team would conduct their own aerodynamic tests to make sure the car is "somewhere in the ballpark'' of having the correct amount of downforce before it is presented to V8 Supercar officials for scrutiny.
Supercar legend Mark Skaife, head of the Car of the Future program, under which new makes such as the Nissan Altima are allowed to compete from next season, said there was no reason why the Kelly's Altima could not win races next year.
Nissan last competed in the Australian Touring Car Championship 20 years ago and the success of its four-wheel drive GTRs drove a wedge between the traditional Holden and Falcon fans and those prepared to support an overseas product.
Rick Kelly said one of the issues the team had to consider was the reaction from V8 supporters.
He said he and the team had been delighted by the backing they received with a new make on the horizon at a season-opening test day at Sandown early this year.
"Everyone, I think, really felt rejuvenated and that the category was changing up a bit and they were very interested to see how that was going to play out,'' he said.
"Throughout the last nine months you've seen that anticipation build and I think you'll really see that in ticket sales to the (season-opening) Clipsal round (in Adelaide) next year.
"I think that's invited a lot of new fans to come to V8 Supercar racing and enjoy it.''
Kelly said Holdens and Falcons now had a much smaller market share and it was important to open Supercar racing up to brands which had become more popular in the showrooms.
