Yes, too subtle for most to notice though IMHO - a little too much 'Red Bull' and not enough Infiniti for me still! I'd like to see them doing it 'properly' if you see what I mean.I wonder if they've been thrown off course a little as I seem to remember hearing a rumour that F1 would go over to 4-pot engines. Maybe they developed the Deltawing with the DIG-T engine and have have been thrown because F1 is moving to smaller V6's instead? All speculation by me of course!Although, I'm sure the DIG technology could transfer to a V6.... I'd like to see that!
