the "Minidiesel Société". As for the usual versions, the Commerciale was somewhat hampered by its small aperture for the luggage area - especially when compared to more modern competitors. 650/500 A "Minidue" had been rumoured for some time, but most were expecting the fitment of a Moto Guzzi 650 cc V-twin engine, since Moto Guzzi was another company owned by de Tomaso at the time. A few prototypes were even built with this engine, but the amount of work it would have taken to make the motorcycle unit suitable for a car made the project unfeasible. Instead, Innocenti chose to stick to Daihatsu engines. First shown at the Turin Auto Show in November 1984, the two-cylinder, short-stroke 617 cc "Mini 650" was also available as a better equipped "SE" model. The 650 received a silver-painted asymmetric grille, while the SE model had model-specific hubcaps divided into threes. While not very powerful at , the two-cylinder engine was surprisingly smooth-running thanks to the use of twin balance shafts. The dashboard was also unique to the 650 and was quite spartan: for instance, it had no door to the glove compartment. In the rear, the reflective bar between the taillights was replaced by a black plastic unit. The "650" was succeeded by the three-cylinder 550 cc (660 cc from late 1990) "Mini 500", which went on sale in January 1988. These engines all came from the Daihatsu Cuore rather than the bigger Charade. The 550 cc Innocenti 500 (with L or more luxurious LS equipment) was first shown in November 1987 and replaced the preceding "650" since engine-supplier Daihatsu had ended production of the outdated two-cylinder engine. The carburetted 500 offered at 6400 rpm for a top speed. In late 1988, about 75 percent of Innocentis sold in the home market were 500s. Outside Italy, this car also found some popularity in France, where its 3CV tax rating was as low as that of the considerably less habitable Fiat 126. From the outside, the 500 could be identified by some visual alterations as recently used on the 990: a horizontally divided grille with a prominent "i" logo larger bumpers which incorporated the lower air intake up front. The rear number plate moved up, to between the taillights. The interior was also updated, with round gauges and new upholstery. The LS also gained an asymmetrically divided folding rear seat.
