In 2014, Loris started participating in the Renault Clio Cup Benelux and competed against touring car veterans such as Sebastiaan and Michael Bleekemolen with a fifth place in the championship in his first year as a result with two podiums in a field of thirty cars and he also won the championship for rookies. In 2015 he did several races in TCR series, Clio Cup Benelux and also the Audi TT Cup with great success, including eleven podiums, three pole positions and six victories. He also became the youngest driver on the podium in the history of TCR International with second place in Buriram.

From 2016, Loris made the transition to GT racing, where he would first participate in three races in the ADAC GT Masters with the Callaway C7 Whelen Corvette together with Boris Said and Eric Curran with strong top ten results. In 2017 he entered the McLaren GT Junior driver program and won it, so he was selected as a McLaren GT Junior driver in the Blancpain GT Series, but unfortunately the McLaren proved to be unreliable and uncompetitive, under which the contract was terminated after only two races. For 2018, the focus was mainly on GT3 races in the Blancpain GT Series, after Gottfried Grasser of GRT Grasser invited Loris to test at the Hungaroring, where he proved to be the fastest of all the candidates who were testing and was given the seat. During the same period, Loris entered the NASCAR Whelen Euro Series, a completely new championship for him in a new car, but one to which he was able to adapt very quickly due to his experience in different categories of motor racing. After almost winning his first race in the NASCAR Whelen Euro Series and seeing how much potential there was in NASCAR, Hezemans decided to dedicate himself full-time to a career in NASCAR.
