Ferrari team principal Stefano Domenicali hailed Fernando Alonso's Singapore Grand Prix win as an "exceptional performance".
Alonso produced a flawless display for 61 laps under the lights of the Marina Bay street circuit that included two safety car periods and relentless pressure from runner-up Sebastian Vettel in his Red Bull.
With three wins in his last five races and back-to-back successes for the first time in two years, Alonso is now a man to be feared as the title fight heads into the final four grands prix.
The double world champion has closed the gap on championship leader Mark Webber, who was third, to 11 points, leapfrogging bitter rival Lewis Hamilton into second in the standings following the Briton's second successive DNF.
An ebullient Domenicali said: "Fernando again proved what he is made of, in terms of driving ability and his mental attitude.
"The first and most important brick in this particular wall was put in place with pole position.
"If we had not started from the front, it would most likely have been impossible to overtake the Red Bull (of Vettel) which proved to be so strong on track."
Domenicali, however, knows there can be no let-up, neither from Alonso nor the team in terms of providing him with a car to win more races, and potentially the title.
"We have now picked up two very nice wins in a row on tracks with completely different characteristics, but we are still behind in both championships," added Domenicali.
"We must continue to work like this, if at all possible, multiplying our efforts to try and fight all the way to the finish.
"The maths will be done only at the end, on November 14 in Abu Dhabi."
After triumphing on a high-speed track such as Monza in the Italian Grand Prix a fortnight ago, and now on a twisty street circuit such as Singapore, Alonso feels Ferrari have laid down a marker.
"This win is very significant," said Alonso.
"We wanted to confirm our success in Monza at a very different type of track, and we succeeded at the end of a very hard and extremely stressful race.
"Singapore is physically the toughest race of the season, with no room to breathe with 24 corners.
"So this win means a lot to keep fighting in the championship, and with four races to go it seems we can be competitive for those."
Like Domenicali, the Spaniard is fully expecting the battle for the crown to go all the way to the wire.
"The dance towards the title sees the contenders see-sawing up and down, although Mark is still holding onto a slight lead," added Alonso.
"We must stay calm and concentrate on our own job, without thinking about what the others are doing. What is certain is we will leave nothing to chance.
"The rest of us need to keep catching if we can, and we will do our best, although we do not know if it will be enough to be champion in Abu Dhabi."
Jenson Button salvaged something from a poor day for McLaren with fourth place at the flag, while Nico Rosberg was fifth in his Mercedes, followed by the Williams of Rubens Barrichello and Renault's Robert Kubica.
Post-race 20-second penalties for Force India's Adrian Sutil and Williams' Nico Hulkenberg relegated them to ninth and 10th, with Ferrari's Felipe Massa elevated to eighth after starting at the back of the grid.
