The T-80 was the first Russian MBT to use a gas-turbine engine. The original 1,000 hp GTD-1000T, although significantly more powerful than the conventional diesel engines, was much criticized for its noise level, low reliability, much larger fuel consumption and greater thermal signature. This is one of the reasons (barring the competition between plants) why the T-90 MBT uses the uprated diesel instead of the gas-turbine. However, the new 1250 hp GTD-1250 is far more reliable. The large fuel consumption is compensated somewhat by an auxiliary GTA-18 18 kW powerpack. There were also variants of T-80 MBT using a diesel engine, for example T-80UD with 1,000 hp 6TD diesel.
