Crushingly dominant is the best way to describe Mercedes\u2019s start to this Formula One season. Boring may be another way to define it.Before the sixth race in Monaco on Sunday, Mercedes has scored five successive one-two finishes in five grands prix. Another around the streets of the principality and it will set a Formula One record, bettering the five by Ferrari at the end of 2002.Following the latest one-two in the Spanish Grand Prix at the Circuit de Barcelona-Catalunya, where just months earlier Ferrari had emerged quickest from preseason testing, there was talk in the paddock of Mercedes becoming the first team to go through a season invincible.Toto Wolff, the team principal, laughed off the suggestion, saying it was \u201cnot realistic.\u201d\u201cWe have to stay humble and not see success as guaranteed,\u201d he said. \u201cWe have had five fantastic performances and five one-twos, but we don\u2019t take it for granted. It is not just saying it. It is really the mind-set we have.\u201dFranz Tost, the Toro Rosso team principal, has said that Mercedes\u2019s dominance is having a detrimental effect on the sport.\u201cFrom the race entertainment, I must say it was not so exciting because we have two cars in front which are winning race after race,\u201d he said.\u201cThat\u2019s not, I think, the best for Formula One because it starts to become boring, as far as friends of mine say to me, who don\u2019t watch F1 any more because always the same team is winning. This, I think, is not good.\u201dEven the five-time champion Lewis Hamilton, a beneficiary of Mercedes\u2019s pre-eminence, has said Formula One is \u201cnot as much fun\u201d when the battle is intrateam rather than with a rival. (Hamilton is one of the five drivers who have surpassed the three titles won by Niki Lauda, who died on Monday.)\u201cThat\u2019s what Formula One is about, the exciting part when you\u2019re competing against one or two other teams who are also bringing their A-game,\u201d Hamilton said.\u201cIt puts another spanner in the works, and often, when the cars are close, there are strengths and weaknesses in both teams, and how you play those and benefit from those is awesome.\u201cBut when that\u2019s not there, it\u2019s definitely not as exciting from a competition point of view,\u201d Hamilton said. \u201cRacing within a team, it\u2019s not really how Formula One should be in my opinion. But it is how it is right now, and it has been like that in the past as well.\u201dWolff said that within his team \u201cthe energy levels, contentment, are higher than ever,\u201d and that the team wants to continue to set new levels of excellence as it seeks a record six consecutive drivers\u2019 and constructors\u2019 titles. Ferrari won five in a row from 2000-4.\u201cThat is an exciting objective,\u201d Wolff said. \u201cIf you find your purpose within a group that is on that journey, you have a very strong force. When you walk around, what you hear and see are content people enjoying what they do.\u201cIt\u2019s a calm, positive atmosphere, and a tremendous privilege to be in a situation where we have won five championships and we\u2019ve earned the possibility of going for a sixth one that hasn\u2019t been done before.\u201dThe drivers\u2019 title already appears to be a private Mercedes battle, with Hamilton\u2019s three wins to the two of Valtteri Bottas giving him a seven-point advantage.Max Verstappen of Red Bull is their nearest rival, 46 points behind Hamilton.As for Ferrari, its season has unraveled alarmingly since it left Spain at the end of the second preseason test, when the team had a clear advantage over Mercedes. Ferrari is now 96 points down, while Sebastian Vettel is 48 points back and Charles Leclerc 55.It has not been all one-way traffic for Mercedes. It inherited a one-two in Bahrain, the second race, when Leclerc\u2019s car had a cylinder issue and loss of power 11 laps from the finish. Leclerc finished third.He had the potential to start from pole position in Azerbaijan, the fourth race, when he appeared to be the fastest until crashing in the second of the three qualifying sessions. He could finish only fifth in the race behind Bottas, the winner.In Spain, Ferrari made a power-unit upgrade.Binotto, the new team principal, said it was done to intensify its development program. But the change didn\u2019t help much. Ferrari had the third quickest car, behind not only Mercedes, but also Red Bull.Vettel, a four-time champion, has found his No. 1 status within the team threatened by Leclerc. \u201cInside the team,\u201d Vettel said, \u201cwe are not happy\u201d about the overall performance.\u201cIt is what it is, and we have to look at the positives and try to build on those,\u201d he said. \u201cWe need to stay focused and do our job, and I am sure the results will come.\u201cObviously, Spain was a big step back in terms of pace, with Mercedes being far away. I know everybody is very keen to do better, but it is a question of time. It is not easy. Other people are doing a very good job and you need to respect that.\u201dBinotto, who stepped up from technical director to replace Maurizio Arrivabene over the winter, also said he was \u201cnot happy with the points we\u2019ve scored so far.\u201d\u201cWe missed a great opportunity in Bahrain where we certainly could have had a fantastic result compared to the one we did, and in Baku, we could have had a better race, certainly a better qualifying,\u201d he said. \u201cTo sum up, we are missing points compared to where we believe our potential is.\u201cThe world championship is far from over,\u201d Binotto said. \u201cWe still have a good car. The competition is very, very strong, which was known, it\u2019s not a surprise, but we are still in the battle.\u201dVettel and Verstappen have each had two third-place finishes, with Leclerc the other, behind Mercedes\u2019s commanding duo.Verstappen, who recently learned he will have a home grand prix in the Netherlands in 2020 when a Dutch race returns to the calendar for the first time in 35 years, has performed well for Red Bull, which is using a new power unit from Honda.Honda replaced Renault as supplier at the end of last season.\u201cIt\u2019s good but not as good as Mercedes,\u201d Verstappen said about his car. \u201cWe clearly still need to work harder and bring better things to the car. It\u2019s good to see we closed the gap to Ferrari, so I\u2019m happy about that.\u201dChristian Horner, the Red Bull team principal, said in an interview that \u201cthere are encouraging signs.\u201d\u201cWe\u2019ve areas where we know we need to improve, but generally it has been a positive start to the year,\u201d he said.\u201cHopefully, we can continue to reduce that gap. We have an aggressive development program on both the chassis and engine, and we can continue to push in both those areas.\u201dMcLaren leads the congested midfield, in fourth place, with just 16 points separating it and ninth-place Toro Rosso. Williams is last and has not scored a point.
