Kiwi driver Simon Evans has dominated the New Zealand Touring Car Championship the past two seasons but will move to a different category at the end of this summer.
The 26-year-old holds an almost unassailable lead in the 2016-17 championship with one round remaining and will complete three straight titles (he won the final SuperTourer championship in 2014-15) at Hampton Downs in a fortnight.
But that will mark the end of his time in the series.
"This will probably be my last V8 round at Hampton Downs," said Evans. "We have another plan coming up. The weekend after is the New Zealand Endurance Championship. We are about to launch our new car for that. It will probably be the only one in New Zealand.
"We finished second last year but I'd like to win that."
