Sorry for a bit of a threadjack, but,
In a modern car engine, at optimal load, how much does efficiency change across the RPM band and how much room for improvement is there?
It would make decent sense from a simplicity (and thus cost) standpoint to use a transmission/drive like Old Mechanic has and keep an engine at constant load, varying the RPM when you change driving conditions, if the RPM range of high-efficiency (at high load) is wide enough. I've always thought CVTs were a wonderful idea, with current implementations only falling short in that they're sometimes lossy due to friction, and have limited range of ratio.
