SMG vs SSG gearbox
Hi,
... FWIW, found this text describing the SSG:
However, biggest surprise is the introduction of SSG (Sequential Shift Gearbox) to 325 and 330i. BMW claimed it is a simplified version of the M3’s sequential manual box, but it is actually built around the regular 5-speed manual rather than the M3's 6-speeder and most importantly, the shift mechanism is supplied by Italy's Magneti-Marelli instead of Siemens. You might remember Magneti-Marelli is the maker of Alfa Romeo's Selespeed and Ferrari's F1 system, so SSG should be much cheaper than the SMG. Unfortunately, shift response is far slower than SMG. There are 3 modes: in "Normal" mode, shift takes 400-500ms; in "Sport" mode, it is reduced to 250-300ms but shift quality is less smooth; in "Launch" mode, 150ms can be achieved from first to second gear.
Has anyone found a road test of SSG?
