Career
At the end of the 2008 season, Pentus tested for GP2 Series teams DPR and Racing Engineering with respectable results considering his previous racing experience. In November, he tested with Fortec Motorsport in the Formula Renault 3.5 Series test in Valencia and again impressed, comparing favourably with F3 graduates Edoardo Mortara and Jaime Alguersuari during the two days. Fortec would later sign Pentus for the 2009 season on January 30, 2009.
He scored his first points in the series when he finished second in the feature race at the Circuit de Catalunya, having started nineteenth.
This earned Pentus a bonus point for the most places gained in the race. He went on to finish sixteenth in the overall standings and finished sixth in the rookie championship overall standings.
Pentus stayed with Fortec to compete in the 2010 Formula Renault 3.5 Series. He finished the 2010 season in 4th place overall.
Pentus joined EPIC Racing team for the 2011 season, and eventually finished the disappointing season 24th.
In 2014 Sten Pentus switched from single-seaters to GT racing, competing in the Blancpain Sprint series with the Bhaitech team in a McLaren MP4-12C GT3. (key) (Races in bold indicate pole position) (Races in italics indicate fastest lap)
