Force India believes it still needs to be at the top of its game if it is going to hold off Lotus in the constructors' championship, despite its Russian Grand Prix podium finish.
Sergio Perez capitalised on a risky tyre strategy to take third place behind Lewis Hamilton and Sebastian Vettel at Sochi.
That result has helped strengthen Force India's fifth place position in the constructors' championship, with it now 26 points clear of Lotus with four rounds remaining.
But although encouraged with its strong form in recent races, deputy team principal Bob Fernley is not taking anything for granted.
"It's put some clean air between us, and we need it because Lotus are a good team," explained Fernley.
"It only takes a good weekend for them and we are under pressure again, so we need to be on our game."
More pace needed
Although the great strategy call paid off in Russia, Fernley is well aware that Force India does not have the pace to be mixing it right at the front in normal circumstances.
However, its push up the grid has left it in the position where good opportunities are available.
"It is not easy for us," he said. "We are not quite there.
"This was an opportunity we took with both hands, and managed to deliver with a little bit of luck. But on pure merit we are not there quite yet."
