After racing for Andretti in the 2015/16 and 2016/17 ABB FIA Formula E Championships, Frijns made a comeback to the series with Envision Virgin Racing in 2018, taking the place of Alex Lynn.

Frijns wasn’t born into racing, in fact it was a family friend who gave the Dutchman his first experience in a kart. After travelling to a few races and experiencing the smells and sounds of racing it became obvious Frijns wanted to take racing up more competitively. He was given a quad bike to play with in the garden and was forever being told to get off it by his mother after ruining the garden but a young Frijns was getting the feel for driving.

He progressed through the single-seater ranks and won titles in a number of junior categories including Formula BMW Europe and Formula Renault 2.0 Eurocup. He won the 2012 World Series by Renault 3.5 at his first attempt with the last driver to achieve such a feat being Robert Kubica in 2005.

The Dutch driver and GP2 race winner has been recognised for his talent throughout his career testing for both Sauber and Red Bull Racing at the Formula 1 young driver test in Abu Dhabi.

In 2013, Frijns joined Sauber as an official test driver and took part in a partial season of GP2 picking up one victory and two podium finishes. Frijns later joined Caterham F1 as a test driver for 2014. Since 2015, Frijns has raced in the Blancpain GT Series and, in 2018, in the DTM series with Audi Sport.

Just missing out on a podium finish in the 2018/19 season, Frijns rounded off the season in fourth place in New York City after claiming his second win in the very last race in NYC. For the 2019/20 season, Frijns once again pilots Envision Virgin Racing's Audi-powered Gen2 challenger alongside British driver Sam Bird.
