It is starting to look a little bit ominous for Red Bull’s rivals now. Three wins out of four for Sebastian Vettel and its difficult to see who will stop Vettel and Red Bull retaining the Drivers and Constructors crown.

But there is hope and there is still a long way to go. Red Bull will have off days and it will then be up to the likes of McLaren, Mercedes, Ferrari and Lotus Renault to take full advantage.

You can only run out of superlatives to describe Sebastian Vettel. Not for the first time this season, Seb yet again qualified on pole and then went onto win the race. Is there anyone who can stop the 2010 World Champion?

Despite having a spin in the First Free Practice session and not having completed any laps in Second Free Practice, Vettel never looked back. Once again, the former Toro Rosso driver put in a stunning lap on Saturday to take pole.

There was no repeat of the poor start to the race in China and Vettel guided ‘Kinky Kylie’ to the chequered flag for his third win of the season. The RB7 and Vettel are a match made in heaven and the likes of Lewis Hamilton, Mark Webber, Jenson Button and Fernando Alonso have a stern job on their hands if they are to get the better of Seb.

A 1-2 in the race was the icing on the cake for Christian Horner and Red Bull. It was a much better weekend for Webber and he will have left Istanbul in bullish mood.

Qualifying on the front row will have been a relief for the Australian and even though Nico Rosberg got past him on the first lap, Webber was able to get past Rosberg soon after. Mark also got past Fernando Alonso late on in the race to take second.

But I still feel Webber does need a race win sooner rather than later. He will not want to be playing second fiddle to his team-mate throughout the year. However Mark does appear to have got his season back on track and he will go to Spain with some momentum on his side.

One man who will have been happy with his weekends work will have been Fernando Alonso. Again he qualified 5th and the Spaniard drove the wheels off the Ferrari in the race.

Fernando gave Red Bull something to think about throughout the race and the Ferrari hierarchy and Luca di Montezemolo will have been delighted with the result in Turkey.

You can never underestimate Alonso even if he has not got the best of cars and on Sunday he proved he was back. The Turkish weekend may be the springboard for Alonso and Ferrari to go on and have a strong season.

It was not the best of weekends for Felipe Massa but the Brazilian has still made a decent start to the 2011 season and I’m sure Turkey was just a blip.

Mercedes also had a decent weekend despite Michael Schumacher finishing outside the points. The team showed a lot of promise in the Free Practice sessions and Nico Rosberg was able to take that form into qualifying whereas Schumacher did not.

Nico qualified a superb 3rd just behind the two Red Bull drivers and made a great start to the race by getting past Webber. Rosberg will have been hoping to finish on the podium but he can still take many positives from the weekend.

Mercedes will be hoping to compete against the likes of Red Bull, McLaren and Ferrari on a regular basis. And from what we have seen in the last two races, Mercedes are heading in the right direction and significant improvements have been made.

But Schumacher will no doubt have been frustrated with the way things went at Turkey. Everything appeared rosy in Free Practice and you seemed to have got the impression we were starting to see the best of Michael.

But qualifying did not exactly go to plan and Schumi will not have been pleased qualifying eighth. Things were about to get a whole lot worse for the seven-time Champion. The German finished outside the points to cap off a disappointing end to what promised to be decent weekend for Schumi.

It was literally a case of damage limitation for McLaren as Lewis Hamilton finished 4th and Jenson Button came home in 6th. Both drivers were off the pace and never really got close to the Red Bull’s.

It could have been a different story had Lewis got past Webber on the first lap but it was not to be. Hamilton also had a number of battles in the race with Jenson which was pretty exciting at least for the spectator. Not if you were Martin Whitmarsh and McLaren.

Finishing 4th was a decent result for Hamilton but he will be hoping for better in Spain. Same goes for Button as well. Jenson was struggling with his tyres in his final stint and Rosberg got past him to take 5th in the latter stages of the race.

It was just one of those weekends for McLaren but they will bounce back and I have no doubts about that. Lewis and Jenson will have better weekends and they will win races before the end of the season.

Both Lotus Renault drivers Nick Heidfeld and Vitaly Petrov finished the race in 7th and 8th. The last two races have seen Renault fall back into the midfield but Petrov has made a solid start to this season and the Russian can be happy with the way he has performed so far this year.

Nick Heidfeld has recovered well after his failure in Australia but you just wonder if Robert Kubica had been driving the car, would Renault have picked up more points? Everyone in Formula One wishes Kubica a speedy recovery and hopefully we will see him in a Formula One car soon.

Also well done to Sebastian Buemi for picking up two valuable points for Toro Rosso. Both Buemi and Jaime Alguersuari are under pressure to deliver with Daniel Ricciardo waiting in the wings. But give credit to Buemi and finishing in the points will do his confidence the world of good.

And finally Kamui Kobayashi. After starting the race from the back, the Japanese star finished the race in 10th. Everyone was looking forward to seeing Kobayashi come through the field and he did not disappoint.

Kamui is bound to be a favourite amongst the paddock and with Formula One fans. And dare I say it; some of the big teams might well be looking to sign him up in the near future. So Sauber have got a big job on their hands if they want to hold on to Kobayashi.

The European adventure continues as we head toSpainfor the next Grand Prix. The season so far has been Vettel and Red Bull domination and its difficult to see who can stop them.
