This BMW 1 Series is supposed to be 2011 BMW 1 Series M Coupe and it was caught testing in Munich. It is featured with a carbon fibre roof (you can see a small part of it in the main photo), with 19 inch wheels covered by 265/35 R19 Michelin tires. It’s a good thing that we can see this BMW 1 Series almost with no camouflages but I also miss the normal BMW’s camouflage sticks.
2011 BMW 1 Series M Coupe has also wider rear wheel arches and carbon ceramic brakes (the photographer could see this only at the rear side but it is possible to be also on the front size). After these visual details, people have made 2 phone: the first is that this is a 2011 BMW 1 Series M Coupe and the second one is that this is a 2011 BMW 1 Series Coupe xDrive.
BMW said that they are not going to build a 1 Series M Coupe so we don’t know what to belive from these informations found on the internet. I can say that all we have now are just these spy photos.
