than those of the larger diesel while noise levels increased noticeably. In Finland, the price difference with the equal six-cylinder diesel was only just over two percent; owners expected to save money by being in much lower tax and insurance brackets. The diesel had originally been intended to be sold North America first and foremost, but in actuality the D24 only became available in the North American market beginning with the 1980 model year. After the US diesel market collapsed, sales decreased to ever smaller numbers and it was discontinued after the 1985 model year. No diesels were actually delivered during 1980 as Volvo had a hard time meeting the EPA's environmental standards. The federalized diesel developed a claimed , but was not certified for sale in California. Badges Nomenclature The 200-series cars were identified initially by badges on their trunk lid or rear hatch in a manner similar to the system used for previous models. The 4 and 6 codes soon lost their original meaning as signifying the number of cylinders with the introduction of B17-engined four-cylinder Volvo 260s for export to Greece and Israel in the late 1970s. There was also a six-cylinder 240 GLT in some markets, as well as both six- and five-cylinder diesels labelled 240. The second digit now only denoted how luxurious the car was. By June 1982, with the introduction of the model year 1983 Volvos, the third digit too lost its meaning and the 242/244/245 became simply the 240. 1974–1982: three digits (in the format 2XY, where X usually represents the number of cylinders and Y represents the doors: 2 for coupés, 4 for sedans, 5 for station wagons) followed by trim level letters. For example; 244 and 245 were four-cylinder sedans and wagons respectively and 264 and 265 six-cylinder sedans and wagons respectively. 1983–1993: 240 (or 260 until 1985) followed by trim level letters (third digit no longer reflects body style, although it is reflected in the engine compartment label, as well as on the label in the trunk on sedans or under the main cargo compartment storage lid on wagons). Special models (e.g. Polar and Torslanda) sometimes omit the 240. For the American market: 1975–1979: trim level letters preceded by three digits (in the format 2XY, where X usually represents the number of cylinders and Y represents the doors: 2 for coupés (only for the 262C. 242 are two-door sedans),
