The refreshed BMW 1 Series Convertible and Coupe made its world premiere at the Detroit Auto Show today. In these photos, it is quite noticeable that an ‘air curtain’ front bumper was used on the 128i models. It is an aerodynamic aid that diverts air from the front bumper. An optional ‘aero’ wheel is also available for the 128i. It also sports a new interior color, Gloss White, which adds a fresh sporty look to the vehicle. Enjoy these photos!
