Fuel Economy

I remember over and over criticism of the M1 Abrams fuel economy.

About 0.6 miles per gallon.

The critics condemned the turbine engine for this abysmal fuel consumption.

They failed to tell us what other tanks got for mileage.

The British Centurion, very much in service at the time the M1 was being developed just barely broke 0.5 miles per gallon on road and was around 0.25 mpg cross country.  But that was a gas engine.

The M60, which the M1 replaced does get better mileage with its diesel engine, but not a lot better; 0.78 miles per gallon.
