the same, inside and out, as did the regular Minitre. At the time of introduction (April 1984), this engine was not only the smallest passenger car diesel in the world, but also had the highest specific output of any naturally aspirated diesel engine in series production; it thus made for a surprisingly spirited performer. Introduced as part of an effort to bring Innocenti production above the threshold of profitability, around 20,000 cars annually, the Minidiesel sold very well. The diesel took thirty percent of the overall production with nearly no negative effect on sales of the petrol versions, a considerably bigger share than the expected twenty percent. It was helped by a lack of real competitors: by 1988 it still only had to compete with the 1.3 litre Fiat Uno and Panda diesels, as well as the Volkswagen Polo diesel, all of which were in a higher tax bracket and had higher fuel consumption. 990 In Turin 1986, the longer 990 was presented. This version had a wheelbase which was extended by and was available with either the naturally aspirated petrol or diesel 1 L engines. In addition to a more useful back seat, the 990 also had a more sloped windscreen for somewhat better aerodynamics. Classified as a five-seater, even two adults would still find the rear seat uncomfortable. A well balanced design, the longer wheelbase version can be hard to identify, if not for the missing pillar in the glass of the door, and the forward placement of the mirrors. The luggage space also increased somewhat, with rather than . The 990 also received bigger bumpers and a new grille with horizontal bars and the Innocenti logo, a stylised "i". The rear number plate was moved up to between the rear lights. The 990's rear seat folded and was divided down the middle. The 990 was an adaptation of a 1982 concept executed by the Embo carrozzeria, using the longer chassis of the Mini Traveller. Excepting the turbo, the shorter 1-litre versions were taken out of production in July 1987. The 990 was available as the SL, and as a better-equipped SE version. There was also a "Minitre Commerciale", continuing the earlier Mini 90 Commerciale two-seater van. When the longer 990 arrived there was also a 990 C (for "Commerciale") and also a 990 diesel C. In France, the earlier short wheelbase diesel van was briefly available as
