BAC, also known as the Briggs Automotive Company, introduced the Mono in 2011, after two years of development. Using a carbon-fiber composite construction over a steel chassis, the Mono is a superlight, single-seat sports car inspired by motorsports. It features an FIA-compliant rollover structure, construction principles borrowed from DTM race cars, and a suspension system specifically developed for track use. Tipping the scales at only 600 kg (1,323), it’s among the lightest road-legal vehicles you can buy. The sports car was updated in 2016, when it received a new engine and more carbon-fiber components.
