The category, for 14 to 17 year old racers, was held for the first time in 2017 with a pilot series of eight races.
It pits young drivers against one another in identical junior racing specification versions of the same car used in the senior UK Clio Cup (based on the Clio Renault Sport 220 Trophy).
The cars are acknowledged as being the most technically advanced and safest in the junior saloon car racing market place…
This year Clio Cup Junior is expanding to 12 races at six different circuits – the first two races are at Silverstone on the weekend of 24/25 March.
Jack will compete for the same team – MRM Racing – with which he won 2017’s title.
The 16-year-old from Belfast won the inaugural crown in a nail-biting final round at Brands Hatch last November.
Meanwhile Lorcan Hanafin, the driver who started seven of 2017’s eight races from pole position, has also announced a return with the Team Pyro squad.
Lorcan, aged only 15 and from Guiseley, won three of the races in 2017 as well and, having missed out on the Champion’s prize – a free registration into the senior Renault UK Clio Cup valued at £18,000 – he will surely be eager to put that right this time around.
Another youngster after the big prize will be Louis Doyle. The 15-year-old from Chorley has re-signed for the JamSport Racing team. Last year he achieved a second place result in his first outing in the category – also his first-ever car race – and has already started his pre-season testing programme with tuition from top touring car racer Tom Ingram.
