Lewis Hamilton eased to a second victory in a week at the Mexican Grand Prix.
The Briton survived a big lock up into the first corner, which saw him skate across the grass, but was untroubled after that.
Nico Rosberg held off an attack from Max Verstappen to eventually claim second but who should be on the final podium place is still hotly debated.
Verstappen crossed the finish line third but was awarded a five-second penalty almost immediately for replicating Hamilton’s move in a battle with Sebastian Vettel.
The German was promoted to third and takes that position but many feel he may have deserved his own penalty for another battle with Daniel Ricciardo.
The Ferrari appeared to move under braking when the Australian looked to pass at Turn 4 with two laps to go, a violation of the new guidelines introduced at the US Grand Prix following Verstappen’s defensive tactics.
As it is, Ricciardo was also promoted a place to fourth following his teammate’s penalty with the Dutchman settling for fifth.
Kimi Raikkonen barged his way past Nico Hulkenberg, in a move that resulted in the Force India spinning, to take sixth, with the German in seventh.
Valtteri Bottas was eighth ahead of his teammate Felipe Massa who, begrudgingly for all the home crowd, kept Sergio Perez behind him for 50 laps as the two men completed the top 10.
The action in the closing laps was the only significant events to take place as the highly durable medium compound tyres neutralised the race.
It was Vettel’s later pit-stop to switch to the medium that saw him have enough pace to catch Verstappen, and Ricciardo opting for a two-stop strategy, opting for the softs for the final 20 laps, that brought the race to life.
Verstappen looked to keep Rosberg firmly on his toes, utilising slow traffic to have one attempt at passing the Mercedes, but after that failed the championship leader maintained second position.
Also there was a little chaos in the opening lap behind the leaders as the tight confines so Pascal Wehrlein tapped into Marcus Ericsson with the Manor driver forced to retire.
Other than that it was the top 10 places filled by the five fastest teams.
Ericsson recovered from the first lap contact to finish 11th ahead of the two McLaren’s who had disappointing races in 12th and 13th.
Palmer and Nasr were 14th and 15th with Carlos Sainz and Daniil Kvyat both being given time-penalties for driving infractions as they finished 16th and 18th.
Magnussen was sandwiched between the two Toro Rosso’s in 17th with the two Haas’ and Esteban Ocon bringing up the field.
Hamilton’s lonely but dominant win sees him close the gap to Rosberg to 19 points but it isn’t the improvement he was hoping for.
Instead he will have to hope the previous perils of the Brazilian Grand Prix at Interlagos can help generate the non-generic result he needs if he wants to be crowned world champion again.
