"They are a threat because if you are not as smart and you didn't see how to make the most of these new regulations, then you'll certainly suffer in the coming season".
The new vehicle ran at the home of the British Grand Prix on Wednesday as part of a promotional day, with teams limited to 100km (62 miles) on special Pirelli tires. "We need to prove ourselves again - against our own expectations and against our competitors". We start the season with zero points, so we're taking nothing for granted and there's absolutely no feeling of entitlement to be at the front.
Hamilton has also won 51 of the 100 grands prix in the V6 turbo era that started in 2014 and four of the last five championships. The buzz really starts at the beginning of the year when you see the auto coming together.
"Some components surrender what feels like a giant step of half a kilo, others just a few grams, but collectively each of these victories add up to a handful of kilos that have been invested back in the vehicle on aerodynamics, suspension and power unit to bring performance".More news: Arsene Wenger pinpoints one United weakness that caused PSG defeat
"Lewis spent some time travelling", said Wolff.
"We have to start from scratch".
"He has been able to fully reset after a season that was not always easy for him".
"I'm really looking forward to the next step of our journey together with Mercedes and embarking on what's not been done before", he added.More news: Illegal Alien Confesses to Murder of New York Woman: 'We Are Devastated'
Mercedes' 2018 auto, the W09, helped Lewis Hamilton to the fifth drivers' title of his career - and his fourth with Mercedes - while in the hands of both Hamilton and Bottas, Mercedes secured their fifth straight constructors' title, in the face of fierce competition from chief rivals Ferrari. Let us know in the comments! "There is nothing, no credit that you can take from previous seasons into a new one, and this is why we embrace every year with the same motivation and hunger as every season before".
"The handling of the W09 was a big improvement over the rather idiosyncratic W08. We have worked hard on the suspension and aerodynamic characteristics to deliver a vehicle that will be much kinder to its tyres - enough, we hope, to allow us to be competitive at all phases of the race and at each track on the calendar".
Mercedes will use Wednesday's launch event as a chance to finalise preparations for the first pre-season test in Barcelona next week, ahead of the first race in Australia on March 17.
