In 1982 at the Geneva Auto Show, Ferrari replaced the Mondial 8 with an even more powerful version, the Mondial Quattrovalvole. The "Quattrovalvole" name referred to the 4 (quattro) valve per cylinder engine that increased the engine power, but also made it easier to comply with US emissions legislation. The car was produced between 1982 and 1985, during which time 1145 examples were produced, in both right and left hand drive versions, together with various world market specification models.
The Mondial Quattrovalvole featured a wedge body shape theme with the radiator grille beneath the front bumper. The overall shape was identical to the preceding model, including the black plastic wrap around bumpers front and rear, together with the large trapezoidal air intake grilles for the engine bay on the body sides behind the doors, and paired circular rear light assemblies.
Although the exterior remained unchanged, apart from the replacement of the Mondial 8 badge with Mondial Quattovalvole badging to the tail panel, the interior was lightly modified, mainly in respect of the center console layout.
The console was extended forward to meet the front bulkhead, and the ventilation controls incorporated into it, whilst the radio position moved from behind the gear change to a more clearly visible location ahead of it. The door panels had revised pattern pockets and pulls, whilst the leather rim steering wheel became plain spoke (instead of slotted) with a satin black finish.
Under the hood there was a four valves per cylinder heads, the V8 engine fitted with Bosch K Jetronic fuel injection and Marelli MED 803A Digiplex electronic ignition to produce a claimed 235bhp for main European market versions, and 230bhp for US market versions. Top speed went up to 149 mph.
The engine was transversely mounted in unit with the all synchromesh five speed transmission assembly, which was below, and to the rear of the engine’s wet sump. The model featured independent suspension via wishbones, coil springs and hydraulic shock absorbers all round, with front and rear anti roll bars.
