BMW has been testing their new BMW 1-Series soft top cabriolet over at the Nurburgring track in Germany. The small cabriolet is based on the BMW CS1 Concept (picture above) shown back in 2002 at the Geneva Motor Show. The CS1 featured a 1.8 litre Valvetronic engine mated to an SMG gearbox. What differentiates this from it’s older brother the BMW 3-series convertible is the latter has a powered hard top while the 1-series cabriolet will be smaller and will have a normal canvas top. Technically, according to BMW’s naming scheme this should be called a 2-series, but it appears that BMW is leaning more towards calling it a 1-series cabriolet.
