{{lang|de|Moltke}} and {{lang|de|Goeben}} were powered by four-shaft [[Parsons turbine]]s in two sets and 24 coal-fired Schulz-Thornycroft boilers, divided into four boiler rooms.{{sfn|Staff|p=12}} The boilers were composed of one steam drum and three water drums apiece,{{sfn|Staff|p=14}} and produced steam at {{convert|16|atm|psi|lk=on}}. They were vented through two large [[funnel (ship)|funnels]] spaced widely apart. After 1916, the boilers were supplemented with tar-oil sprayers that were used to increase the burn rate of the low quality [[lignite]] coal available to Germany. The Parsons turbines were divided into high- and low-pressure pairs.{{sfn|Staff|p=14}} The low-pressure turbines were the inner pair, and were placed in the aft engine room. The high-pressure turbines were on either side of the low-pressure pair, and were located in the forward wing rooms. The turbines powered four propellers, {{cvt|3.74|m|ftin}} in diameter.{{sfn|Gröner|p=54}}

The ships' power-plants delivered a rated {{convert|52000|PS|shp|0}} and a top speed of {{convert|25.5|kn}}. However, in trials {{lang|de|Moltke}} attained {{convert|85782|PS|shp}} and a top speed of {{convert|28.4|kn}}; {{lang|de|Goeben}}{{'}}s power-plant produced only a slightly lower horsepower and top speed.{{sfn|Campbell & Sieche|p=152}} At {{convert|14|kn}}, the ships had a range of {{convert|4,120|nmi|lk=in}}.{{sfn|Staff|p=14}} The {{lang|de|Moltke}}-class ships were equipped with 6 turbo [[Electrical generator|generators]] that delivered {{convert|1,200|kW|hp|abbr=on}} of power at 225 volts.{{sfn|Staff|p=14}} The ships were designed to carry 1,000 tons of coal, although in practice they could store up to 3,100 tons. Fuel consumption on the six-hour forced trial was 0.667 kilogram per horsepower-hour at {{convert|76795|PS|shp}}, and 0.712 kg per horsepower-hour at {{convert|71275|PS|shp}}, respectively for the two ships.{{sfn|Gröner|p=54}}
