The 2009 BMW 1-Series is available as either a 2-door coupe or convertible with a power folding soft top. Largely unchanged following its introduction for the 2008 model year, the lineup includes 128i and 135i models. The 1-Series slides in below the BMW 3-Series in size and price. The 1-Series engines are 3.0L inline 6-cylinders that are found within the 3-Series. The BMW 128i has 230 hp, while the 135i has 300 hp, due to its being turbocharged. All models have a standard 6-speed manual transmission, or a 6-speed automatic is optional. Available safety features for the 2009 BMW 1-series include ABS, traction control, antiskid system, side-curtain airbags on the coupes and front airbags on both. A sunroof and split folding rear seat are standard on the 1-Series coupes. An available Premium Package includes leather upholstery, a power front seat and BMW's Assist system. A Sport Package includes upgraded trim, sport suspension on the 128i (standard on the 135i) and sport bucket seats. Other options include aluminum trim and heated front seats.
