( February 2018 ) The model year ( MY ) of a product is a number used worldwide, but with a high level of prominence in North America, to describe approximately when a product was produced, and it usually indicates the coinciding base specification ( design revision number ) of that product. The model year and the actual calendar year of production rarely coincide. For example, a North American 2015 model year automobile is available during most of the 2015 calendar year, but is usually also available from the third quarter of 2014 because production of the 2015 model began in July or August 2014, continuing to May / June / July 2015. The variables of build date and design revision number are semi-independent. There is no natural law that forces one to be strictly correlated to the other, other than that : future design revisions can not have been built in the past, and most products, in most contexts, tend to be built to the design revision that was the latest one at the time of building.

Sloan extended the idea of yearly fashion - change from clothing to automobiles in the 1920s. His company, General Motors, was the first to introduce planned obsolescence ( in cars ) by means of making the production date, and thus the car 's newness or lack of it, visually discernible. European and Japanese automakers can utilise the term `` model year '' in respect of model availability dates in North American markets : these often receive updated models significantly later than domestic markets, especially in the event of unforeseen slow sales causing an inventory build - up of earlier versions. The practice of identifying revisions of automobiles by their model year is strongest in Canada and the United States. Typically, complete vehicle redesigns of long - standing models occur in cycles of at least five years, with one or two facelifts during the model cycle, and manufacturers introduce such redesigns at various times throughout a calendar year. Introductions of new models are often phased in around the world, meaning that a 2004 model of a particular vehicle may actually refer to two entirely different vehicles in different countries. Therefore, the more common practice for enthusiasts and motoring writers in other countries is to identify major revisions using the manufacturer 's identifier for each revision. For instance, aficionados will classify the Holden Commodore ( a popular Australian car ) according to the following series : VB ( introduced in 1978 ), VC ( 1980 ), VH ( 1981 ), VK ( 1984 ), VL ( 1986 ), VN ( 1988 ), VP ( 1991 ), VR ( 1993 ), VS ( 1995 ), VT ( 1997 ), VX ( 2000 ), VY ( 2002 ), VZ ( 2004 ), VE ( 2006 ) and VF ( 2013 ). This is done for the simple reason of making the cars more easily distinguished. Further information : Vehicle Identification Number § Model year encoding Europe In the automotive industry the model year is absolutely defined only by the manufacturer, and not by any local vehicle registration practices or marketing opinions. Industry practice varies between markets according both to the level of exports to North America, and to the extent to which US - owned subsidiaries dominate the domestic automarket. In the 1960s and 1970s, many new models were traditionally introduced at the London or Paris motor shows during October, and manufacturers owned by US corporations as well as domestically controlled UK auto - makers tended to follow US auto - industry conventions in respect of model years. The concept was never so universally applied in Europe as in North America, however, and since the 1980s, the more commercially critical European Motor Shows have been the March Geneva Motor Show and the September Frankfurt Motor Show or Paris Motor Show. New models have increasingly been launched in June or July even in the UK, where the two remaining US - owned subsidiaries no longer design and build distinctively British Ford and Vauxhall models. All this has left the US - style model - year concept increasingly absent from the European domestic automarkets. An automotive model year is categorically defined by the 10th digit of the vehicle identification number ( VIN ), and simply indicates any manufacturer - specified evolution in mid-cycle of a model range - such as revised paint options, trim options or any other minor specification change. The 10th VIN digit does not relate to the calendar year which the car is built, although the two may coincide. For example, a vehicle produced between July 2006 and June 2007 may have a 7 as the 10th digit of the VIN, and another vehicle produced between July 2007 and June 2008 may have an 8 in the 10th digit - with the change - over date varying depending on manufacturer, model and year. United States In the United States, automobile model - year sales traditionally begin with the fourth quarter of the preceding year. So model year refers to the sales model year ; for example, vehicles sold during the period from October 1 to September 30 of the following year belong to a single model year. In addition, the launch of the new model - year has long been coordinated to the launch of the traditional new television season ( as defined by A.C. Nielsen ) in late September, because of the heavy dependence between television to offer products from automakers to advertise, and the car companies to launch their new models at a high - profile time of year. In other cases, products of a previous model year can continue production, especially if a newer model has n't yet been released. In that case, the model year remains the same until a new model is introduced. This is to ensure that the model will be seen by the public, and will actually sell a number of vehicles before a new vehicle - model is produced, and people will look at the newer model rather than the previous one. In the United States, for regulation purposes ( such as VIN numbering and EPA emissions certification ), government authorities allow cars of a given model year to be sold starting on January 1 of the previous calendar year. For example, this means that a 2019 model year vehicle can legally go on sale on January 1, 2018. This has resulted in a few cars in the following model year being introduced in advertisements during the NFL 's Super Bowl in February. A notable example of an `` early '' model year launch would be the Ford Mustang, introduced as an early 1965 model ( sometimes `` 19641⁄2 '' ) in April 1964 at the World 's Fair, several months before the official start of the 1965 model year in August 1964.
