More to the point is the way it changes up when you approach the rev
limiter. Or rather the max they allow in a gear. If you want to hit the
limiter on a manual there's nothing to stop you - so why in a so called
manual mode? Also not being able to start in a high gear on ice is plain
stupid.

They just keep on getting better.

There was quite a delay before 5 speeders for the more powerful models
arrived. The pressing need (in Europe) was to improve the fuel consumption
of the 'bread and butter' auto models so they were closer to the manual
without ruining the performance. Indeed my first 5 speed auto, an early 24
valve 525 E34, actually returned better highway mileage than the manual
due to taller gearing. It was easy to get in the high '30s when sticking
to UK speed limits on motorways.
