Renault F1 signing Nico Hulkenberg has rubbished suggestions that he could return to the Le Mans 24 Hours this year, saying he’s totally committed to his new team. Hulkenberg won Le Mans at his first attempt in 2015 for Porsche alongside Nick Tandy and Earl Bamber – both of whom have been elevated to full-time drives with Porsche’s LMP1 team in the FIA World Endurance Championship.
