Max Verstappen dominated the Styrian Grand Prix on Sunday, as reigning champion Lewis Hamilton rolled in a distant second in his Mercedes, complaining that the Red Bulls are "faster, they're just faster."

The Dutchman started from pole in his Red Bull, led throughout and finished more than 35 seconds head of Briton Hamilton.

Mercedes' Finnish racer Valtteri Bottas, who started from the pit lane, was third, edging out the second Red Bull of Mexican Sergio Perez.

"That is the most dominant win we've had so far this season against Mercedes," said Red Bull's team principal Christian Horner after his team's fourth straight victory.

Verstappen, who has claimed three of those victories, agreed.

"Looking at the gap in the end, yes," Verstappen said. "But above all, the overall balance of the car was the best so far."

Mercedes won the constructors' title the last seven seasons. In that span, Hamilton won six driver titles, interrupted only by then team-mate Nic Rosberg in 2016.

A fourth straight race without a victory represents a significant drought.

"It's been the first race in eight years where we were lacking pace," said Mercedes' team boss Toto Wolff.

On Sunday, Verstappen dominated and increased his lead over Hamilton to 18 points while Red Bull, sponsored by an Austrian company, increased their lead in the constructors' championship to 40 points.

"Unbelievable. The car was on fire," said Verstappen on team radio at the finish. "Another win at home feels really good."

"It's looking really good," he said after climbing out of his car. "We just have to keep pushing really hard and I'm confident we can do a really good job again."

Hamilton spent much of the race expressing frustration on his inability to cut into Verstappen's lead as once again Mercedes were not quite as quick as Red Bull, although he did pick up a bonus point for the fastest lap time.

"It was a bit of a lonely race really," Hamilton said. "I was trying to keep up with those guys but, the speed they have – they've obviously made some big improvements. It was impossible to keep up."

"They continue to keep pulling out those laps and on the straights we lose a lot. Nonetheless, we got good points as a team today and we've just got to keep pushing," Hamilton added. "They're faster, they're just faster. There's not a lot I can do in that respect. I've just got to keep trying to do the best I can do each weekend."

"We need to find some performance, we need an upgrade of some sort, we need to push," Hamilton said. "We've got to find some performance from somewhere."

Bottas, who started from the third row after a three-place penalty for spinning in the pit lane, was happy with his finish.

"I think from where I started, this was the maximum today, so it's good," he said.
