Packard's Electromatic Clutch was not electromagnetic, but an electrically-modified, vacuum-operated, automatic clutch system, which was something of a workaround until they came up with their own automatic tranmsission - the Ultramatic.

This feature debuted on 1941 models, and an entire issue of the company's service newsletter, SL Vol. 15, No. 2, was devoted to product information. Later on, there was a Serviceman's Training Booklet on Electromatic Clutch.

Unfortunately, when problems arose and the dealer network was no longer around to help, a lot of these systems were gutted or completely removed by those who didn't understand the technology. Personally, I thinks it's a wonderful example of technology, but others will disagree.

I can't speak to axle ratios, but if you want improved fuel economy, know that the Electromatic Clutch was available with overdrive transmission.
