The M1 Abrams is powered by a 1500 hp (1119 kW) Honeywell AGT1500 (initially created by Lycoming) gas turbine, and a six speed (four forward, two reverse) Allison X-1100-3B Hydro-Kinetic Automatic transmission, giving it a governed best speed of 45 mph (72 km/h) on paved roads, and 30 mph (48 km/h) cross-country guide to silos construction . With the engine governor removed, speeds of around 60 mph (one hundred km/h) are achievable on an improved surface nonetheless, harm to the drive train (specifically to the tracks) and an increased danger of injuries to the crew can occur at speeds above 45 mph. The tank can be fueled with diesel fuel, kerosene, any grade of MOGAS (motor gasoline), or JP-4 or JP-8 jet fuel the U.S. Army utilizes JP-8 jet fuel in order to simplify logistics. The gas turbine propulsion technique has verified rather trustworthy in practice and combat, but its high fuel consumption is a serious logistic problem (starting up the turbine alone consumes 40 liters of fuel).
The high speed, high temperature jet blast emitted from the rear of M1 Abrams tanks makes it difficult for the infantry to proceed shadowing the tank in urban combat. The turbine is noisy, comparable to a helicopter engine, although the noise character (pitch) is considerably distinct from a contemporary diesel tank engine, decreasing the audible distance of the sound, hence the nickname, "Whispering Death". Future US tanks may possibly return to reciprocating engines for propulsion, as 4- stroke diesel engines have established rather productive in other modern day heavy tanks, e.g above-ground-are-the-safe-way-of-storing-combustibles more information . the Leopard two, Challenger 2 and Merkava. The modest size, simplicity, power-to-weight ratio, and simple removal/replacement of the turbine power pack does, nevertheless, present important positive aspects more than any proposed reciprocating replacement.
The Abrams can be carried by the C-five Galaxy and C-17 Globemaster III. The limited capacity (a single combat-prepared tank or two transport-ready tanks in a C-five, 1 combat-prepared tank in a C- 17) triggered significant logistical issues when deploying the tanks for the First Gulf War, even though there was enough time for 1,848 tanks to be transported by ship steel storage tank .
