The Moskvitch G4 were sports cars from Moskvitch released in 1963. Like the G3, they used the same engine as the Moskvitch 407. In 1965, all three G4's were re-engined with units based on the engine in the Moskvitch 408. These engines were fitted with twin Weber 40DCO carburettors, advanced valve timing, and new camshafts giving 81 bhp (60 kW; 82 PS). The G4's were then redesignated as G4A's.
