The sound of the Leopard 2 engine, a tank developed by Krauss-Maffei in the 1970s for the West German Army. The tank first entered service in 1979 and succeeded the earlier Leopard 1 as the main battle tank of the German Army.
This Leopard 2 tank engine is V-12 twin-turbo diesel 47.6 liter engine and 1500 horsepower.
Its sound is amazing.
