context_page_description: The Alfa Romeo 75, sold in North America as the Milano, is a compact executive car produced by the Italian automaker Alfa Romeo between 1985 and 1992. The Alfa 75 was commercially quite successful: in only three years, 236,907 cars were produced, and by the end of production in 1992, around 386,767 had been built.
  The Alfa Romeo 75 was the last model released before Alfa Romeo was acquired by Fiat.
context_section_description: The 75 featured some unusual technical features, most notably the fact that it was almost perfectly balanced from front to rear. This was achieved by using transaxle schema — mounting the standard five-speed gearbox and clutch in the rear connected to the rear differential (rear-wheel drive). The front suspension was a torsion bar and shock absorber combination and the rear an expensive de Dion tube assembled with shock absorbers; these designs were intended to optimize the car's handling; moreover the rear brake discs were fitted at the centre of the rear axle, near the gearbox-differential group. The engine crankshaft was bolted directly to the two-segment driveshaft, which ran the length of the underside from the engine block to the gearbox and rotated at the speed of the engine. The shaft segments were joined with elastomeric 'doughnuts' to prevent vibration and engine/gearbox damage. The 2.0 L Twin Spark and the 3.0 Litre V6 were equipped with a limited slip differential.
  The 75 featured a then-advanced dashboard-mounted diagnostic computer, called Alfa Romeo Control, capable of monitoring the engine systems and alerting the drivers of potential faults.
  The 75 engine range at launch featured four-cylinder 1.6-, 1.8- and 2.0-litre petrol carbureted engines, a 2.0-litre intercooled turbodiesel made by VM Motori, and a 2.5-litre fuel injected V6. In 1986, the 75 Turbo was introduced, which featured a fuel-injected 1,779 cc twin-cam engine using Garrett T3 turbocharger, intercooler and oil cooler.
  In 1987, a 3.0-litre V6 was added to the range and the 2.0 L Alfa Romeo Twin Cam engine was redesigned to have now two spark plugs per cylinder, the engine was named as Twin Spark. With fuel injection and variable valve timing this engine produced 148 PS (109 kW; 146 hp). This was an early example of a production engine using variable valve timing, though the first to do so was in Alfa Romeo's own Spider in 1980. In North America, where the car was known as the Milano, only the 2.5 and 3.0 V6 engines were available, from 1987 to 1989.
  The North American 2.5-litres were fundamentally different from their European counterparts. Due to federal regulations, some modifications were required. Most noticeable from the outside were the 'America' bumpers, with the typical rubber accordions in them. Furthermore, these bumpers had thick (and heavy) shock-absorbing material inside them and in addition, they were mounted to the vehicle on shock absorbers. To accommodate these shock absorbers, the 'America'-bodies were slightly different from the European ones. Other changes relative to the European model were:
  A 67-litre fuel tank which was located behind the rear seats, reducing the boot capacity from 500 L (18 cu ft) to 300 L (11 cu ft).
  Side-markers in the bumpers
  Exhaust silencer sticking out from under the bumper at the r/h side of the vehicle instead of the centre
  Reinforcements in the doors and boot lid
  Hooks underneath the bonnet, to keep the bonnet in position in a crash
  The North American cars also had different equipment levels (depending on the version: Milano Silver, Milano Gold or Milano Platinum). L/h and r/h electrically adjustable outside mirrors, electrically reclining seats and cruise control were usually optional in Europe. The car was also available with a 3-speed ZF automatic gearbox option for the 2.5 V6. Other, more common options such as electrically operated rear windows and an A/C system were standard in the USA. The USA-cars also had different upholstery styles and of course different dashboard panels also indicating speed in mph, oil pressure in psi and coolant temperature in degrees F, and as a final touch the AR control was different, including a seat belt warning light. Some North American specification Milanos were sold in Switzerland (When catalytic converters were made mandatory in 1987).
  The European-spec 2.5 V6 (2.5 6V Iniezione or 2.5QV) was officially sold only between 1985 and 1987, although some of them were not registered until 1989. Relatively few of them were sold (about 2,800 units), especially
