We know a few things about the car
1) Williams kerrs unit
2)cosworth engine
3)The car is supposed to be an evolution of the MR01 incorporating development areas they did not have time for in 2012 and the greater understanding they say they know have.
4)The area they are reporting to be concentrating on the most this year is the aerodynamic's. With the absence of wirth and the knew approach using wind tunnel to coroberate data it will be interesting to see the results of their toil.

So there you go, some albeit small news about the Mr02. The team sound hopefull that they are on schedule (though this is an old article - and they have been very quite since then)
I think this years car will be a step up for them - still will not be midfield but will be mixing it up with caterham in the race this season. In short slow and sustainaable growth (just like caterham)
Over to you know, what do you guys know
