Rosberg is back out on track after his early spin so it doesn't seem like he did too much damage.
@Keith: Does crashing into other drivers fall in the "crazy stuff happening around him" column?
@MohdMukaram: Not yet, still in the garage.
Hulkenberg has jumped into third in the 2014 Force India. These are his first F1 laps of the season.
@Noski: It's pretty sunny out there today. Classic winter testing conditions.
@JamesDuncan: I think that's a bit simplistic. All the teams knew about the rules for 2014 at the same time and Mercedes prepared best. The key to their success was getting chassis and engine departments working entirely for the same goal. Ferrari had the same advantage with an in-house engine department but didn't capitalise. Renault and Red Bull weren't working as closely as they are now and Renault and Ferrari simply weren't as smart or ambitious with the packaging of their engines.
@AnderssonOuissi: The McLaren is very tightly packaged at the back and hasn't had any problems with burning bodywork, so appears to have a good cooling system. The MP4-30 does have quite a large airbox which feeds the engine and supplies cooling to the rear of the car. The Red Bull, however, has very small sidepod openings and airbox, which is really rather impressive.
@DylanRomanos: It's an interesting comparison. A big part of the difference to 2004 is the tyres. Back then we were in the middle of a tyre war, now Pirelli is producing tyres that degrade on purpose. Of course, the engines are also down on power from the 2004 V10s and they also sound nothing like as exciting. But you have to ask yourself, would you rather out-and-out quick lap times or exciting racing? There's no right answer, but a lot of casual fans were put off by the racing in 2004 because of the dominance of the Schumacher-Ferrari-Bridgestone package.
@AnderssonOuissi: The law of diminishing returns.
@Jayathran: But all the manufacturers knew about the rules at the same time, so why wouldn't they have started early as well? Mercedes, arguably, had more resources than Renault, but what is Ferrari's excuse? In fact, ironically, one of the big advantages Mercedes had was the knowledge it gained when working with McLaren in the build up to 2009 on KERS. That was very important for the ERS development for the new engines, but of course McLaren didn't benefit so much from that last year as the works Mercedes team.
@fdespotovski: That is a very good point!
But most track records on circuits that haven't changed still date back to 2004
The McLaren has now been out for its first installation lap of the day.
@drynog: Interlagos is pretty much unchanged. The big advantage of the new cars is that they are turbocharged, so don't suffer from the loss of atmospheric pressure at Sao Paulo's altitude that the old naturally aspirated engines had.
