Platform Heritage

The BMW 5 Series is an executive car manufactured and marketed by BMW since 1972. It is the successor to the BMW New Class sedans and is currently in its eighth generation. The car is sold as either a sedan or, since 1991, a station wagon (marketed as "Touring"). A 5-door fastback (marketed as "Gran Turismo") was sold between 2009 and 2017. Each successive generation has been given an internal G-code designation since 2017. Previously, a F-code designation was used between 2010 and 2016, while an E-code designation was used between 1972 and 2010. These are used to distinguish each model and generation from each other. The first generation of the 5 Series was powered by naturally aspirated four-cylinder and six-cylinder petrol engines. Following generations have been powered by four-cylinder, six-cylinder, V8 and V10 engines that are either naturally aspirated or turbocharged. Since 1982, diesel engines have been included in the 5 Series range. The 5 Series is BMW's second-best-selling model after the 3 Series. On 29 January 2008, the 5 millionth 5 Series was manufactured, a 530d sedan in Carbon Black Metallic. It is BMW’s oldest nameplate still in production and the first model line to use "Series" in the name, debuting the three-digit model naming convention still used today. Since the E28, all generations of 5 Series have included an "M" model, called the BMW M5.
