Is spec 4.0 the latest spec or has their been a newer spec released?
Wazari implied there were further advanced stages when he said Spec 4.0 and Spec 4.xx.
One would assume that by testing the engine would of made even further progress.
According to Wazari, the Spec. 4 concept existed in some form at or before winter testing but it was not chosen due to a number of factors (weight, CoG among others) despite a supposed power advantage. Fast forward to the end of the season where Hasegawa said a Spec. 4 engine was ready to use but ultimately was not, presumably because of chassis modification and/or penalty considerations. We can then infer based on Wazari's use of Spec. 4.xx that, like any good development engineering team with a moving target, that they have not been sitting still with the new power unit even if it hasn't run on-track yet. This could be another contributing factor to Honda not to bringing Spec. 4 when it was ready: it may have shown McLaren something they were not privy to yet and Honda did not want them to see with Renault in the picture.
