Interesting article over at the race regarding the engine upgrade. Binoto says he is still unsure when it will be ready. Apparently its "brand new technology on the hybrid side" which still need homologations and certifications among other things.
On a positive note, he said "It will be as soon as possible because we believe that running it as much as we can this season will be of interest for the next season.". this goes against my theory that they would wait as long as possible to not over-run it and need a 5th. I suppose they WANT to see how durable it is. Maybe we WILL see it before Turkey. [-o<
