i've read somewhere Renault might have done a complete engine overhaul, could this be indeed a sign that they actually have? I remember last year all renault-powered cars were very conservative with the pods/engine covers, only redbull had a 'tight' package, and all teams suffered huge cooling problems.
The tightness of the STR10 package suggests that cooling has been resolved?
interesting to see ALL cars, have MUCH bigger air scoops/inlets at the airbox.
