There are two bits of news concerning Lewis Hamilton that will have sent shudders along the F1 pitlane this week.

The first was the time Lewis set in his McLaren during F1’s last official test session at Barcelona; he was quickest out of all 23 drivers, with a time of 1min 20.472sec, fractionally ahead of Mark Webber’s fiendishly rapid looking Red Bull (1min 20.496sec), Felipe Massa’ Ferrari (1min 20.539sec) and Adrian Sutil in the Force India (1min 20.611sec).

Intriguingly, Nico Rosberg managed to out-pace Michael Schumacher in his Mercedes, just, although they didn’t actually run on the same day, so we still don’t know for sure how close to Schuey Rosberg will get.

Hamilton seeks new F1 manager

The second piece of news concerning Lewis Hamilton will, if anything, be even more significant to the rest of the grid, you suspect, because Lewis has announced that he will no longer be managed by his Dad. Hamilton senior is leaving the partnership, it seems, to grow his various other business interests. As a result this will allow Lewis to have his Dad “just as my Dad” he told Autosport. “We always did business things, not father and son things” said Lewis.
