Red Bull Racing team principal Christian Horner says the 'sky is the limit' for his squad this season after it took its maiden victory with a dominant one-two in China.
Sebastian Vettel and Mark Webber were substantially faster than their rivals in the wet today, with third-placed Jenson Button's Brawn 40 seconds adrift at the end.
"It was frustrating in the first two races not to get a podium but now we're firmly on the scoreboard," Horner told the BBC.
"It's a breakthrough result for us. It's a long season ahead, and we can see that we're competitive with both drivers, so I think the sky's the limit."
Designer Adrian Newey and his team are already working on a revised car featuring a double diffuser, which Horner is confident will give the team another major boost.
"The car's been very good in the high-speed corners. It's got a great aero package," he said. "We've got a lot more development steps to come now with the clarity in the regulations, and we know there's more performance that we can see."
He insisted that he remained calm on the pitwall despite the treacherous conditions and the safety car interruptions.
"It was actually very calm," said Horner. "We had a clear strategy that at the earliest opportunity we were looking to close down the race.
"Sebastian put all of our hearts in our mouths by overtaking Jenson when he knew that he still had a stop to go. They were very confident in the car, they had great pace and balance, and the strategy worked very well today."
The team had taken first and third on the grid with Vettel and Webber in dry qualifying, and although that result was achieved on a low fuel load, Horner reckoned victory would have been possible even without the rain.
"If it had been dry it would have been a race against the stopwatch for us on three stops," he said.
"We had gone for a really aggressive strategy in the first stint, and we thought we could beat them by the last pitstop, so we thought we'd have the pace.
"We saw in Q2 yesterday, fuel load for fuel load, tyre for tyre, we were competitive with them. So we decided to roll the dice and have a go at it, and it paid off in both conditions."
