→Turbine engine
Incorporating a modular designed Honeywell 1,500 HP smokeless gas turbine engine that eruns on jet fuel, easily removed once towed to a repair site, serviced and upgraded. The Abrams tank has a governed top speed of 45 mph, with a range of 265 miles on one tank of gas. Speeds of up to 60 mph have been reached with the governor removed, but this results in damage to the transmission and generally makes the tank unservicable quite quickly.

Following a series of critical reports beginning in 1990 and gaining urgency after the 2003 Iraq campaign, the US Army are considering a number of options for replacing the gas turbine with a conventional diesel engine. The main problem is the very high fuel consumption (twice that of an equivalent 1,500 hp tank diesel) which both reduces the tank's range and increases the logistics burden.

The high-temperature jet exhaust is also an issue, as it both creates a large thermal target and is dangerous to infantry working close to the tank, which is a serious issue in urban operations. The turbine engine also sucks in dirt, sand and debris.
