Even if you rarely enlarge the pictures found in kfz-tech.de, in this case it's really worthwhile, perhaps even the second enlargement. If you had seen this starter like I did, while taking photographs, you wouldn't
consider it possible that it could start a combustion engine either. Whereby, this one is not even the smallest in the list. It's not by chance that this one carries the description 'C 60', whereby the 'C' stands for 'compact'
and the 60, for it's diameter.
Having a closer look, the question comes to mind, why do we still come across carbon brushes with a collector?, where these are thought to have disappeared from the motor car starter ages ago. The answer is
surprisingly simple: This new starter was developed not only by engineers in Germany, but also by those in Hungary, India, China and Brasil. This of course, also increased the pressure of cost reduction, which
caused a decision to be made against the brushless variation.

Thereby, the little starters are becoming more and more important. As you can gather from the above list, the layout design is concurrent with the reduction in the cubic-capacity (downsizing). As far as the starter is
concerned, it makes no difference whether a turbo-charger is installed or not. Indeed, even a compressor can presumably be handled by the engine management, making a larger starter unnecessary. Despite the
small size, the Bosch company emphasises the fact, that the service life has not been compromised, on the contrary, it has in fact, rather been lengthened.

As can be seen in the above list, also the starters for vehicles fitted with Start-Stop equipment, are absolutely up-to-date, this is shown by a truly remarkable weight-increase of only 600 gr. Obviously, the bearings and
the planetary gears have been strengthened here. The question of why this wasn't necessary in the other types, remains open. However, in the question of Start-Stop equipment, more focus has been placed on the
battery, which obviously has had to undergo even more changes, to take care of this task. 09/13
