Singer ACS: One-Off Safari 911

The Singer ACS (All-terrain Competition Study) is a unique collaboration between Singer Vehicle Design and Tuthill Porsche, designed for off-road racing. Originally based on a 1990 964-generation Porsche 911, it features an air-cooled 3.6-liter engine producing around 450 hp, paired with a five-speed sequential gearbox. Notable modifications include carbon fiber body panels, eight adjustable shock absorbers, and styling reminiscent of the 959 Safari. This build was commissioned as a one-off client request to showcase extensive off-highway capabilities.
