In 1983 the Marcos Mantula was introduced, externally very similar to the old GT, but now powered by a 3.5-litre [[Rover V8 engine|Rover V8]] with a 5-speed gearbox producing {{Convert|190|hp|kW|0|abbr=on}} at 5280 rpm and {{Convert|220|lbft|Nm|0|abbr=on}} of torque at 4000 rpm. This alloy engine weighed less than the previous six-cylinder cast-iron units, reducing overall weight to about 900&nbsp;kg and making the car competitive against other Rover-powered sports cars such as TVR and Morgan. When tested by Motorweek, the Mantula completed 0-60&nbsp;mph (97&nbsp;km/h) in 5.7 seconds, with a top speed of {{Convert|136.9|mph|km/h|0|abbr=on}}.<ref>{{Cite news |date=1986-10-11 |title=TVR 350i: The Rivals |url=https://x.com/motormobilias/status/1774865078124204382 |work=Motorweek}}</ref> The engine evolved into the Rover Vitesse EFi engine, and later Mantulas were fitted with the 3.9 EFi. In 1986 the model was made available as a convertible, the Marcos Spyder, which would outsell the coupés in later production. 1989 saw the introduction of independent rear suspension, together with the [[Ford Sierra]]'s 7" differential and rear disc brakes. The independent suspension allowed a full-width boot and the relocation of the battery and heater/air conditioning. A total of 170 coupés and 119 Spyders were produced.

Launched in 1991, the Marcos Martina was externally very similar to the Mantula, but with flared front wheel arches. It used the [[Ford Cortina]]'s 2-litre four-cylinder engine, steering and suspension, and approximately 80 were produced. Originally available as kits or factory-built, the cars were all factory-built from 1992. Production of the Mantula and Martina ceased in 1993.
