The next-gen BMW 1 Series has been spied a number of times before, but today we caught it testing in cold weather conditions in Northern Europe. The previously spied model was a turbocharged model with twin tailpipes, but this prototype has a naturally aspirated engine as we only managed to see a single tailpipe in these spy shots — which by the way, also reveal that the 2012 model will come with LED taillights and a twin kidney grille. The compact variant will probably sport a 105bhp petrol engine and a 136bhp turbo option. Also offered, there could be a 3.0L twin-turbo M1 option mated to a dual-clutch gearbox, the combination helping the car achieve a 0 to 60mph time of 4.7 seconds. Not bad, eh? [via WCF]
