Hi-Tec Oils Racing driver Mark McNally has endured the toughest physical conditions of his motor sports career at today's 200km race of the 300 in Ipswich.

With air temperatures in the mid 30s at Queensland Raceway, it was always going to be a tough day at the office, but it was made worse after McNally's onboard driver cooling systems failed on just the 15th lap of 65. McNally had no chance to take a break at the wheel with the entire race running green with no Safety Car periods.

In the end he finished the race in 27th position and was later treated by medical staff for symptoms of dehydration and heat exhaustion.

McNally showed good pace in the early stages of the race, battling into the top 20 with consistent speed and clean driving.

The hot temperatures and his cool suit failure proved trying for the West Australian, who became heat affected 30 laps from the end of the race, resulting in him dropping back through the field.

The next V8 Supercar event will kick of the Season of Endurance at Phillip Island in Victoria on September 11-13.


Mark McNally - #16 Hi-Tec Oils Holden Commodore:

"It was a really tough day," said McNally.

"The cool box stopped working and the fan about lap 15, I have never been so hot in my life, it was unbearable. I have blistered feet, and the second half of the race really was a battle.

"At the start we had good pace, we went to the softs are were running really well. And then when we went onto the last set of tyres we were trucking along really well. We were about 20th or so, which was a true indication of our speed.

"We were doing really well and it's a shame that we couldn't go on with it. It's one of those things, it is so tough in that sort of heat, it was really hard.

"We have shown that we have a little bit of pace, so we will try and get over this hiccup and move on."
