The BMW 8 Series is a range of grand tourers produced by BMW. The 8 Series was introduced in 1990 under the E31 model code and was only available as a two-door coupe. It is powered by a range of naturally aspirated V8 and V12 petrol engines. The E31 started production just as E24 6 Series production ended, however it is not considered a direct successor. It was later discontinued in 1999 due to poor sales. The model range was later reintroduced in 2018 with the second generation, 8 Series. It is expected to launch in coupe, convertible and four-door Gran Coupe body styles, as the successor to the 6 Series lineup. The 8 Series introduces an inline-six diesel engine and a high-performance M8 model is also expected to be launched in the future. The BMW 8 Series was announced on June 15, 2018 with sales commencing from November 2018. It is currently only available as a coupe (codenamed G15), with the convertible and four-door Gran Coupe variants expected to be introduced soon. Production commenced in late 2018 at the BMW assembly plant in Dingolfing, Germany.
