At just 15 years old, the Edgewater driver was one of six from Australia invited by leading Australian Formula 4 team Dream Motorsport to take part in a test using one of their cars being run by the Confederation of Australian Motorsport.
Formula 4 is the new international single-seater category, which has been introduced by FIA as part of the future pathway to F1 racing via F4, F3 and F2.
Dream Motorsport engineer Wayne Mackie said he had “kept an eye on Calan’s progress” and had been “impressed with his approach and outstanding results”.
“I’ve also been impressed with his maturity and efforts he has made with his sponsors,” he said.
“He could be the full package.”
To take part in the test, Williams had to travel to Wodonga, Victoria.
“The circuit is 1.6km long but the straight is only 300m in length, which means the circuit is very twisty and there is almost no time for resting as you are always turning the wheel, braking or changing gears,” Williams said.
He took part in four runs of about 10 laps each and by the third run, he set his fastest laps.
“My fastest lap was 50.6 seconds, which is an average lap speed of 114km/h,” he said.
“I was happy with how consistent I was able to be especially after just the one day in the Formula 4.”
Mackie said Williams’ performance was “very impressive and he made the whole F4 establishment take note”.
Williams now turns his attention to the WA Formula Ford Championship starting in April.
