I reckon McLaren will surprise a lot of people, they are being panned unfairly based on day one of testing but if they have sorted their big weak area then they'll be relatively ok. The times aren't even close to representative on day 1 for any team, especially McHonda when you consider their whole powertrain has had to effectively be redesigned and they will need to play about with fine tuning a lot of the mapping for the new configuration. There's not a hope in hell they were running anything even close to full power out the box, nobody will but they are more likely than anyone to have ran it in the lowest mode purely and/pr heavy with fuel to check systems work and spot any fundamental weaknesses before they slowly turn it up.
What the hell do the media think it says for Renault if they deem McLaren bad, when they were near 5 seconds slower than McHonda and broke down? The fact the McLaren was a second faster than last years Sauber (a car that is proven and should have been running on more than low power) and less than half a second off the new Force India (which again is just an evolution of last years car and should also have been getting ran harder) on the same tyres is actually mildly impressive.... as is the fact they did more laps than Ferrari, WIlliams, Force India, Toro Rosso etc.
Basically, terrible journalism.
