For 1966, the Quattroporte was further refined on a number of points and received a slight restyling. The double round headlights, a feature previously reserved only for vehicles sold in the US, were now standard on all cars and replaced the single, rectangular units of the first series. The car’s advanced De Dion-type rear axle was replaced by a more traditional rigid rear axle layout with leaf springs that derived from the Mistral. With this revision, the interior noise level was reduced by up to 20 dB when driving at highway speeds, making the Quattroporte not just fast, but luxuriously quiet inside. The interior was further refined with a new dashboard featuring a fully integrated climate-control system as standard equipment. Most Quattroporte I cars of the second series were fitted with the standard 4.2-liter V8 engine, but 64 cars received the larger 4.7-liter unit, and two cars were even equipped with a 4.9-liter engine variant.
