Karting Hegewald spent three seasons racing in professional karting, including a fifth place in the 2002
Junior Monaco Kart Cup at
ICA Junior level, racing against the likes of
Formula Three Euroseries racers
Alexander Sims,
Jean Karl Vernay,
Stefano Coletti and
Jules Bianchi and also
Sébastien Buemi.
Formula BMW For 2005, Hegewald moved to
open-wheel racing by taking part in both the
Formula BMW ADAC series, and the
Formula BMW USA series. He finished 20th in the German championship with six points, and finished 15th in the American series, with 22 points and two poles, including one at the
2005 Canadian Grand Prix-support race in
Montréal. 2006 saw very little improvement for Hegewald, as he finished 13th in the ADAC series, amassing 29 points from 18 races. He again interloped into four rounds of the American series and scored 23 points en route to 14th in that particular championship.
Formula Renault Hegewald signed for the
Oschersleben-based Motorsport Arena team for a dual 2007 campaign in both the
Formula Renault 2.0 Northern European Cup and in the
Formula Renault Eurocup. Compared to a lacklustre Eurocup campaign, Hegewald battled Frank Kechele for the NEC title, and lost out by 79 points – yet Hegewald's three wins and ten podiums were plenty good enough for him to earn second place in the championship. With the team renamed to Motopark Academy for 2008, Hegewald continued in the two championships, hoping for some title success. His results in the pan-European championship improved and he ended up a creditable fifth in the championship with two podiums, however he was outperformed on numerous occasions by team-mate
Valtteri Bottas, who eventually went on to claim the Eurocup after a hard-fought title battle with
Daniel Ricciardo, the highly consistent
Andrea Caldarelli and
Roberto Merhi. In the NEC, Hegewald won only one race out of 14, as he dropped down to third in the championship. Again, Bottas dominated the title race, and Hegewald was also beaten by
António Félix da Costa, as Motopark locked out the top four positions in the championship – Johan Jokinen also finished fourth. Hegewald competed in the second event of the
2009 Formula Renault 3.5 Series season, replacing
Mihai Marinescu at the
Interwetten team. The event took place before the start of the
2009 FIA Formula Two Championship season, to which he also committed.
FIA Formula Two Championship Having competed over the offseason in
Formula Palmer Audi, Hegewald signed up to drive in the relaunched
FIA Formula Two Championship in
2009. He drove car No. 8 in the series, and finished sixth in the championship, including a dominating weekend at Spa, when he took both poles, both fastest laps and both wins. He returned to the championship in
2011 after his GP3 Series campaign.
GP3 Series Hegewald moved to the new
GP3 Series for its inaugural season in
2010. He joined
Nigel Melker and
Renger van der Zande at
RSC Mücke Motorsport. ==Racing record==
