Launched in December 1986, this Quattroporte III ‘Royale’ is the ultimate top-of-the-range version of this behemoth from Maserati’s De Tomaso era. It was also the last Maserati to be fitted with the classic V8 engine from the 5000 GT. For this grand-luxe version, Maserati revised the engine’s power output to 300 bhp, which enabled the Royale to reach 230 km/h despite weighing 2 tonnes. On the outside, there were few changes from the Quattroporte III. These include slightly rounded edges to soften the lines, a new exhaust system, specific gills, new colours and a Royale logo on the rear boot. The already flamboyant interior (which, incidentally, inspired the Biturbo generation) also saw its finish move upmarket, with different colours such as ivory, black and cream. The rear doors also feature folding shelves. The dashboard has also been slightly modified, including the famous Maserati watch. Last but not least, the most notable changes include the adoption of an electric sunroof and a Sensitrok differential.
