BMW is well known for its history of inline-six (straight-six) engines, a layout it continues to use to this day despite most other manufacturers switching to a V6 layout. The more common inline-four and V8 layouts are also produced by BMW, and at times the company has produced inline-three, V10 and V12 engines, BMW also engineered non-production customised engines especially for motorsports which include the M12/13 1.5-Liter straight 4 piston turbocharged engine from 1982 to 1987 for Brabham, Arrows and Benetton Formula One teams, the E41/P83 3.0-Liter V10 from 2000 to 2005 for Williams F1 Team and the P86/8 2.4-Liter V8 for their own F1 team partnering with Sauber F1 from 2006 to 2009, with which the company enjoyed its first and best finish at the 2008 Canadian Grand Prix as a full works F1 manufacturer team, finishing the race with their winning driver Robert Kubica, and Nick Heidfeld in second place.
British super car manufacturer McLaren Automotive, a manufacturer of road-going sports cars based on Formula One technology, decided to work with BMW for the development of their first ever production car—the McLaren F1 in 1993 for the engineering and customization of its engine—the S70, which had a 6.0-Liter 60° V12 DOHC configuration. As only 1,510 units of the cars were produced by McLaren, the S70 engine holds the record of the lowest production engines by BMW to date.
Prototype V16 engines have been made despite not reaching production. These prototypes were the 1987 BMW Goldfisch V16 6.7 litre engine and the 2004 Rolls-Royce 100EX 9.0 litre engine. BMW has also made prototype V6 engines[1]
