The offence relates to a "hole that [had] been fashioned by the competitor in the right-hand side of the engine cover", which had been done to grant the Rebellion crew access to the starter motor - to tap a malfunctioning solenoid to reset it - without having to remove the engine cover and rear bodywork.
Per technical marshals, modifications to the bodywork were found to have been made, not in compliance with the LMP2 regulations, prompting an exclusion for the David Heinemeier Hansson, Nelson Piquet Jr., and Mathias Beche-driven entry, which had finished 3rd overall and second in class.
Rebellion has confirmed plans to appeal the ruling.
This disqualification causes a change to the overall classification for the 2017 24 Hours of Le Mans.
Russia: US Planes in Syria Are Now 'Targets'
Moscow has condemned the US downing of the Syrian government fighter jet after it dropped bombs nears USA partner forces. The shooting down of a Syrian Air Force jet in Syria's airspace is a cynical violation of Syria's sovereignty.
Tung went on to bring Jackie Chan DC Racing's first vehicle in second place in the 85th edition of the fabled endurance race on Sunday.
With the vehicle in breach of regulations, the No. 13 auto shared by Nelson Piquet Jr., Mathias Beche and David Heinemeier Hansson has now lost second place in LMP2 and third place overall.
Jackie Chan DC Racing now finishes 1-2 in LMP2 and 2-3 overall, the No. 37 Oreca of David Cheng, Tristan Gommendy and Alex Brundle the beneficiary, while Signatech Alpine's No. 35 Alpine A470 of Nelson Panciatici, Pierre Ragues and Andre Negrao gets an LMP2 podium after all despite Negrao's late off-course excursion at Arnage corner.
