RENAULT look to build on their best result of the season at Sunday's Mexican Grand Prix.

The Enstone-based Formula 1 team head to the Autódromo Hermanos Rodríguez in high spirits after extending their hold on fourth place in the constructors’ championship to 22 points.

Driver Nico Hulkenberg, who was sixth in last Sunday’s United States Grand Prix in Austin, Texas, said: “It was a very satisfying feeling, but we have three races left so we need to keep the good work coming.”

Teammate Carlos Sainz was seventh as Renault scored 14 points, with their nearest challengers, the Banbury-prepared Haas, leaving empty-handed.

Romain Grosjean retired after just two laps, while Kevin Magnussen, who initially finished ninth, was disqualified after his car used more than the maximum fuel allowance of 105kg.

The latter left Austin in a dejected mood, saying: “What the fans want to see is great racing. We can’t do it because we have to save fuel. It’s disappointing.”

Sergey Sirotkin is expecting a challenging weekend for Grove-based Williams.

The Russian finished a place ahead of teammate Lance Stroll in 15th last week and is expecting a testing race on Sunday.

Sirotkin said: “Due to the high location up in the mountains, the track produces a lot less drag and downforce, which causes the cars to behave quite differently.

“It is a challenging track for both the drivers and teams.”
