From clubbie Toyota Corollas through V8 muscle cars all the way to trucks, the southernmost permanent race circuit in the world continues to hold a key place in New Zealand motorsport.
Invercargill’s Teretonga Park, the circuit that kicked off the careers of Damon and Brendon Leitch, remains a round of the summer motor racing series and most recently hosted the massive trucks of the NAPA Auto Parts NZ Super Truck Championship.
Alex Little of Lower Hutt in a Freightliner Century continued his run of success at Teretonga. He took overall victory across the three races accumulating 55 points to head off Troy Etting of Auckland in a Kenworth (51 points) and Ron Salter of Auckland in a Scania. 
It was the seventh time Little had won the Mobil Delvac 1. He first won the trophy in 2018 and apart from 2024 when Dave West took the honours and 2020 when the pandemic cancelled the event, he has won it every year since. 
Little, Salter and Etting took a race win apiece across the round.
Troy Wheeler of Gisborne rolled his Freightliner onto its side at Bonisch Corner in the second race of the round on Sunday morning, causing that race to be stopped. Wheeler walked to the ambulance and was taken to hospital to be checked.
The Gulf Western Oil Development Series runs in conjunction with the main series and Ricky West of Pukekohe took the honours in his Freightliner from Connor Etting of Auckland (Kenworth) with Craig Mason of Rangiora (KM Bedford) and Peter Bartlett of Lower Hutt (Freightliner) tied for third.
