Just heard TIm Slade on the radio, he was driving for Erebus last year running a private Mercedes in the series. He made it very clear that the biggest issue by far for their poor performance (and Nissan's) is that they simply cannot get the same power or fuel efficiency Ford and Holden are getting.
I know it is tough for new teams but I am surprised Nissan is struggling with this so much (there's factory money involved), does anyone here have any insight into the technical dramas they may be having? TO be clear, he's saying they are down on power and they are thirsty.
