BMW introduced the 1 Series compact in 2004. Initially available only as a five-door hatchback , the 1 Series gained a three-door version and two-door coupe and convertible iterations in 2007. While the first-gen hatchback was redesigned in 2011, the coupe and convertible models remained in dealerships until 2013 and 2014, respectively. In 2011, BMW launched the second-gen five-door hatchback, while the three-door version followed in 2012. Three 3.0-liter, inline-six powertrains were offered in the United States. The entry-level 128i model came with 230 horsepower and 200 pound-feet, the mid-range 135i had 300 horsepower and pound-feet, while the 135is cranked out 320 ponies and 317 pound-feet. As we move closer to the 2015 model year, BMW is readying a mid-life refresh for the second-generation 1 Series.
Expected to debut at the 2014 Paris Motor Show in October, the facelifted 1 Series receives updated front and rear fascias, a slightly revised interior and mild upgrades under the hood. Our spy photographers have already spotted a test vehicle on the road with less than two months before its debut.
