I realise mine will not be a thorough review, however I feeI could still share my limited experience of the continental ecocontact 6 with you. The car was a rental BMW F40 120d xdrive (MY2019/2020) with msport package, which I am not sure comes with upgraded suspensions on the 1 series. Tires were 225/40/18. While I only had the car for two days, I was "lucky" to put it through its paces during storm Ciara, on the 10th of Feb in Edinburgh. I drove through some dry, damp, and wet while it was raining and snowing. Bear in mind there was no snow on the ground, however it was quite cold at 2 degrees Celsius and perceived -5 (according to google at least). I regret not having an IR thermometer with me at the time, however it is safe to say that the tires were considerably colder than ideal both in city driving and short motorway stints. Being eco summer tires, I was surprised by their positive behaviour on cold, wet roads. Today's tire technology is remarkable. While there wasn't enough water to test the aquaplaning resistance at speed, I did try booting the accelerator pedal to see if the tires would struggle to maintain traction. Within the road legal limits, and without looking like a complete hooligan it was impossible to upset the car. This is to say that driving according to the conditions one could get through a mild winter with summer tires, and the ecocontact 6 seems to be no exception.
In terms of comfort I found the 120d more compliant than other msport package bimmers (2,3,5 series) mostly wearing Pirelli P7 Blue, and Goodyear F1 A3. However, it could just be because of softer suspensions. The car was probably a little too stiff for what I think it sets out to be, but absolutely acceptable and comfortable by my standards. The new 1 series doesn't strike my like a performance vehicle of any sorts and somehow seems more cramped in the front than before.
As for the handling, and feedback, nothing noteworthy. The feedback is lacking and steering a little vague on all the bimmer I have driven. The F30 3 series being the least disappointing. Granted I only driven F30 318i and G20 320i. So perhaps the good kit can still be found on the 40i's and M cars, but I am sceptical. The ecocontact 6 did not seem to mute the steering further. Good tire for touring, fits the car and satisfies the need of most of us.
DISCLAIMER: the car had 2255 miles when I collected it, I assume all the mileage was done on this set of tires. I drove some 50-100 miles. The car had xdrive, bmw lingo for AWD, which very sporadically redistributed power, but never because of sudden lost of traction. This was hard to notice, but still present. Finally, why I may have said that summer tires CAN make it through winter, it is not advisable in Scottish weather. These tires performed just fine when they were new and had full tread. However the grooves do get narrower as the tread is reduced. (Any) premium all season tires for those who don't drive big miles would be my recommendation, especially for places like Scotland, where summer temperature are contained. Michelin CrossClimate Plus should not compromise warm/dry performance too much either.
