@Alan: I was saying the point of F1 is to change year on year. Even if its a slight evolution on last year's car, the point of staying ahead in F1 is to adapt and innovate in different areas. Mercedes has been making changes to the rear of this car over the last three weeks alone.
And Hamilton was on the mediums, I saw him flash by with my own two eyes on the white striped tyre.
Apologies for the confusion, Alan.
I think one of the frustrating things for Mercedes last year was that the dominance of its power unit took away from what a superb job it had done on the aero side.
@Coggrit: Well of course the front nose has to be different this year and that will have had an impact on the design of this year's car. As I said, they've been changing little bits over the course of this test alone, as all the teams have.
Not many times to speak of - only four - but I am updating the timing screen as we speak.
@GoldenOldie: Yes, we were just talking about that now in the press room. It's a head-scratcher. But then, this is testing, and the teams can run the cars how they like really. I'm sure there will be clarification sought from the FIA before the season begins properly.
Ericsson gets his first lap time on the board, albeit 16 seconds down on Hamilton's headline time.
@rockedin123: Well F1 has become much more of an engine formula under the new rules, hence the dissatisfaction of guys like Newey. So engine gains now are just as important as aero was in the V8 era.
There's an update for you on Force India's plans. We'll see them back in action tomorrow.
As I've stressed, we don't know fuel loads at this stage - but that is an incredibly impressive medium tyre time from Mercedes. Very ominous.
Still nothing much to report. Sainz and Kvyat the men out on track. We haven't seen any of the big four out on track for a while now.
@Sitank: The factory teams - Mercedes, Red Bull [Renault], Ferrari and McLaren [Honda].
The benefit of spending them all before the start of the season is you start the year with the best power unit possible. As I explained at the beginning of today's coverage, any tokens you spend later on in a season do not apply to engines already used. With only four power units available over the course of a season teams may need to use an 'old' engine later in the year - if it has used tokens later, it will have to then use an un-upgraded engine in those races.
Grosjean has got himself onto the leaderboard, slotting into fourth with a 1:28.122.
@Alan: Both Ferrari and Sauber have been very encouraged by the new engine. The gap was so big to Mercedes last year that really can't be the aim straight away - cutting the gap to Renault is the key and it will be very interesting to see how close those two are this year.
@FishFace0212: I imagine in the afternoons, and perhaps later in the test rather than today.
@legion777: Their reliability wasn't THAT bad last year..... It was good enough to win 16 races.
@Alan: No, I didn't say that. I said I expect it has cut the gap to Renault.
