The Porsche 3512 was a motor racing engine designed by Porsche for use in Formula One in the early 1990s.
Porsche had left Formula One at the end of 1987, after four years supplying TAG-badged Porsche PO1 1.5-litre turbo V6 engines to the McLaren team, but decided to return two years later with a view to create a V12 engine for the newly introduced 3.5-litre normally-aspirated regulations (hence this engine's designation of 3512). After a partnership with the small Onyx team was suggested, in early 1990 the company signed a four-year, 80-million Deutsche Mark (€72 million in 2021) deal with Footwork Arrows, to commence in 1991.
