The BMW technique called for accelerating hard up to 2000 rpm only
and then shifting.  The ETA engine in the 528e and what I pre-
sume is in the recently advertized 325e uses this principle.
It is tuned for plenty of low speed torque, high mileage, and
low red-line.  The red line on the 528e is of the order of 4700
rpm (shades of beetles :-)) and don't try upping it or you'll bend
some valves.  They weakened the valve springs to lower the
drag.  Sigh.
