He may have settled into his new surroundings during the 2013 season, but Lewis Hamilton doesn't expect things to get much easier at Mercedes in year two of their relationship.

It's not that the Briton anticipates friction between personnel - his partnership with Germany's Nico Rosberg is the only one among the top six teams to remain unchanged from last season - rather that the major overhaul of the F1 regulations will shake teams out of the comfort zone they had become accustomed to in recent seasons.

"This is my second season with Mercedes and it now feels like I am a fully-fledged member of the team and that we are nurturing the great relationship we built last year, but it is still going to be a big learning year for all of us," Hamilton intimated, "There is so much new technology on these cars, and so much information to take in and filter out to get down to what really matters, it's going to be a big challenge with changes to driving style and race strategies."

Despite his trepidation, Hamilton admitted that the build-up to Tuesday's unveiling of the W05 had been as stimulating as ever.

"I am excited to find out how the new power unit feels to drive, to hear how it sounds from the cockpit and to compare the job we have done relative to the competition.
