It was and has been in Europe for years, even with leaded petrol. We had 2 star (90 RON) up to 5 star (101 RON) from the 1960's onwards - prior to that it was a bit vague. After lead was removed we had Premium (95 RON) and Super (97 to 99 RON)
In the US the reverse camera has to be working for legal safety reasons. I didn't think that was the case in the UK???
It is frustrating as I suspect it is all working fine but just awaiting a software update.
PZ5 is out now in Europe, not sure about the US.
Significantly improved, especially reduced rolling resistance which was a PZ4 weakness compared to the PS4S and Continental Sport Contact 7
In the UK some of our 99 has no Ethanol. It says E5 but that is a maximum and one supplier, Esso, has no Ethanol in its 99 product still in some parts of the UK.
Ethanol has a higher octane rating then petrol.
That 'stupid fuel hole' is extremely valuable at preventing misfuelling. It is obviously used across the Ford range and saves drivers a lot of money. Misfuelling is a big problem in Europe.
Agree the 'middle lane hoggers' can slow traffic down but ACC wouldn't slow anybody down in this situation as there would be nobody in front to make it slow the middle lane down.
Several cars back but still going at the same speed. Losing a few car lengths makes ZERO difference to your overall journey time.
There are reasons ACC doesn't ride less than a car length at 70mph - never mind the safety implications of being too close to the car in front, short distances...
