Formula 1: Renault engine chief hits back at Red Bull's Newey
Renault chief Cyril Abiteboul has accused Red Bull's Adrian Newey of lying after he blamed the car's problems on the engine.
Recent four-time constructors champions Red Bull finished a lap down on Lewis Hamilton's Mercedes in the opening race of the 2015 season.
Technical boss Newey stated "we've got an engine which is quite a long way behind".
