The BMW 801 was a powerful German 41.8-litre air-cooled 14-cylinder-radial aircraft engine built by BMW and used in a number of German Luftwaffe aircraft of World War II. Production versions of the twin-row engine generated between 1.560 and 2.000 PS. It was the most produced radial engine of Germany in World War II with more than 61.000 built. The 801 was originally intended to replace existing radial types in German transport and utility aircraft. At the time, it was widely agreed among European designers that an inline engine was a requirement for high performance designs due to its smaller frontal area and resulting lower drag. Kurt Tank successfully fitted a BMW 801 to a new fighter design he was working on, and as a result the 801 became best known as the power plant for the famous Focke-Wulf Fw 190. The BMW 801 radial also pioneered the use of what would today be designated an engine control unit: its Kommandogerat engine management system took over the operation of several aviation engine management control parameters of the era, allowing proper operation of the engine with just one throttle lever.
BMW 8 Series
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, G15 8 Series. It is expected to launch in coupe G15, convertible G14, and four-door Gran Coupe G16 body styles, as the successor to the F06/F12/F13 6 Series lineup. The G15 8 Series introduces an inline-six diesel engine, and a high-performance M8 model is also expected to be launched in the future.
1. First generation E31; 1990–1999
Design work of the first generation E31 8 Series began in 1984, with final design phase and production development starting in 1986. The car debuted at the 1989 Frankfurt Motor Show, and was produced until 1999. The 8 Series was designed to move beyond the market of the original E24 6 Series, featuring greater performance and an increased price. The 8 Series was the first road car to offer a V12 engine mated to a 6-speed manual transmission and was one of the first vehicles to be fitted with electronic drive-by-wire throttle. The 8 Series was also among one of BMWs first cars to use a multi-link rear axle.
2. Second generation G14/G15/G16; 2018–present
The BMW 8 Series G14 was announced on June 15, 2018 with sales commencing from November 2018. It was initially available as a coupe codenamed G15, with the convertible G14 and four-door Gran Coupe G16 variants introduced later, succeeding the F06/F12/F13 6 Series lineup. Production commenced in late 2018 at the BMW assembly plant in Dingolfing, Germany.
Direct competitors to the BMW 8 Series coupe and convertible are the Mercedes-Benz S-Class coupe & cabriolet, while the BMW 8 Series Gran Coupe is seen as a flashier alternative to its platform-mate, the more traditional BMW 7 Series, and is expected to compete with the rumored next-generation Mercedes-Benz S-Class four-door coupe.
