BMW Z4 vs. BMW 135i Cabrio - Roadster gegen Cabrio

Roadster or convertible? Which is more fun to drive? AUTO BILD TV compares the BMW Z4 and the 1 Series Convertible. Equipped with the same engine, a longitudinally mounted inline six-cylinder, both feature rear-wheel drive and sporty handling. Technically, they are very similar. But while the 1 Series Convertible boasts a soft top, the true roadster, the BMW Z4, comes with a retractable roof. In addition to the fabric top, the 1 Series also offers space for four. Does this make the 1 Series not only better, but also more of a roadster, than the Z4? We have the answers.
