Fuel efficiency is why they're going with large numbers of gears in 
automatic transmissions. The goal is to keep the engine at peak efficiency 
as much as possible (which makes me wonder why CVT transmissions haven't 
caught on) . One added benefit is less RPM drop between gears which also 
helps acceleration.
