The batteries and the electrical system operate at 24 volts DC. a modified roadwheel distance (8 cm increased distance between the third and fourth roadwheel) and the transfer of additional batteries in battery boxes at the rear. The hull only had slight modifications, i.e. Grouser/icecleats can replace the rubber pads on some track links to increase traction on slippery surfaces. The track is manufactured by the company Diehl, rubber track pads fitted, and is "live" track with rubber bushings between the track links and pins (type: D 640 A). The rubber-mounted shocks were modified to achieve better stability during firing. Drive is through the drive sprockets located at the rear. They are connected to the torsion bars on swing arms, whose deflection is limited by volute springs. It has torsion bar spring mounted roadwheels with seven roadwheel pairs per side. The chassis and the track were taken directly from the Leopard 1. The fuel capacity is 985 liters, which ensures a combined operating time of approximately 48 hours. The auxiliary engine is coupled with five generators to operate at different speeds: Two Metadyn machines in tandem with a flywheel (which is used to store energy during the acceleration and deceleration of the turret) for the power of the elevation and traverse drives, two 380-Hz three-phase generators with a capacity of 20 kVA for the ventilation, fire control and radar systems, and a 300-A 28-volt direct current generator for the electrical system. It consumes, depending on the operational status of the tank, between 10 and 20 liters per hour (l/h). The engine, which has a 3.8 liter capacity, is designed as a multi-fuel engine and produces 66 kW (90 PS). This engine is on the front left of the vehicle, located where the Leopard 1 has an ammunition magazine. The Gepard is also equipped with a Daimler-Benz (type: OM 314) 4-cylinder diesel auxiliary engine for the energy supply system. Even the gearbox (type: 4 HP-250) from ZF Friedrichshafen and the exhaust system with fresh air admixture to reduce the infrared signature were taken from the Leopard 1 MBT. To ensure a steady supply of oil, even in difficult terrain and under extreme skew, the engine is provided with a dry sump forced lubrication. The V-engine with a cylinder angle of 90 degrees has 610 kW at 2200 RPM (830 PS) and consumes, depending on the surface and driving style, around 150 liters per 100 kilometers. The Gepard is based on a slightly modified chassis of the Leopard 1 main battle tank, including the complete drive unit with a 37.4-liter 10-cylinder multi-fuel engine (type: MB 838 CaM 500) with two mechanical superchargers built by MTU. The vehicle is based on the hull of the Leopard 1 tank with a large fully rotating turret carrying the armament-a pair of 35 mm Oerlikon KDA autocannons. The system was tested by the German Bundeswehr but not bought due to budget restrictions and the fielding of the Ozelot Light Flak System (LeFlaSys). To combine this capacity in a single unit, a missile system upgrade that mounts the FIM-92 Stinger MANPADS (in twin packs) to the autocannons was developed. Since the eighties, Stinger teams have been accompanying the Gepard units to take advantage of their long-range scanning capacity. The Dutch ordered 95 vehicles, split into three batches (CA1, CA2 and CA3), which were equipped with Philips radar systems. Belgium ordered 55 vehicles, which were identical to the German version. The first was delivered in December 1976. Each vehicle would thus be about three times the price of a normal Leopard 1. On 5 February 1973, the political decision was made to produce the type in September 1973 the contract was signed with Krauss-Maffei for 432 B2 turrets and 420 hulls with a total value of DM1,200,000,000. The Germans made a small preseries of both the B1 and B2R. In 1971, twelve second phase B prototypes were ordered the same year the Dutch army ordered a CA preseries of five vehicles based on a parallel development that had used a German 0-series Leopard 1 vehicle made available by the German government in March 1970 as the C-prototype. On 25 June 1970, it was decided to use the 35 mm type. In 1969, construction began of four A prototypes testing both 30 and 35 mm guns. The Gepard was developed from 1963 onwards.
