Briggs Automotive Company (BAC) Limited is a British car manufacturer that created Mono, a road-legal sports car with only one seat. BAC is based in the city of Liverpool, United Kingdom, Mono cars are exported to 47 countries.

Briggs Automotive Company (BAC) was founded by brothers Neill (Director of Product Development) and Ian Briggs (design director) in 2009. The Briggs brothers consulted for car brands including Mercedes, Porsche, Bentley and Ford on design and engineering projects, until they decided to expand their creative potential with a product from scratch.

The result was the BAC Mono, a lightweight, single-seater, open-top, road-legal sports car.

The first BAC Mono was produced in 2011 and made its inaugural public appearance at the Retro Classics show in Stuttgart, Germany.

The first iteration of the BAC Mono was originally powered by a Ford Duratec 2.3-litre four-cylinder naturally aspirated petrol engine, heavily modified by Cosworth, to produce 280 bhp (209 kW) at 7,700 rpm. It is mounted longitudinally and mated to an electronically controlled, paddle-shift, six-speed sequential Hewland transmission with a limited-slip differential.

The Mono weighs 540 kg (1,190 lb), resulting in a power-to-weight ratio of 518 bhp per tonne. It delivered performance figures of 0–62 mph (0–100 km/h) in 2.8 seconds and a top speed of 170 mph (274 km/h). BAC aimed for an equal weight distribution, 48/52 front/rear, and as low of a centre of gravity as possible when designing the Mono.

The car was constructed in carbon fibre with a tubular steel driver safety cell, complete with an FIA-compliant rollover protection system - similar in concept to a DTM race car. The rose-jointed, aero-profiled pushrod suspension featured adjustable dampers that can be altered based on driving on either the road or track.

The Mono's design is said to be inspired by a science fiction aesthetic and also the robot in Bjork's music video for the song "All Is Full of Love".
