Following the regular ACS1 comes the ACS1 Cabrio by German tuning specialists AC Schnitzer. Just like its coupe sibling, the BMW ACS 1 Cabrio has gone through some power upgrades resulting in a range topping 135i with 360 hp, 123d with 240 hp and the 120d with 200 hp.

The additional power comes accompanied with a height-adjustable race suspension, exhaust silencer with chromed tail trims and a speedometer which now measures up to 320 km/h. The interior is adorned with silver-carbon details and aluminium accessories, new gear knob, pedals and velours floor mats.

Needless to say that AC Schnitzer also has a body kit available for the new BMW 1 Series convertible. The front skirt is less rounded than the factory spec 1 cabrio and comes with a diagonal grille insert, the rear now features a new rear skirt lip and diffuser giving the convertible a more powerful look. The ACS1 Cabrio sits on 17, 18 or 19 inch alloy or racing wheels.
