About

The 2025 BAC Mono R is a single-seat, road-legal track weapon from Briggs Automotive Company, powered by a naturally aspirated 2.5-liter four-cylinder Mountune engine producing 343 horsepower at 8,600 RPM. Constructed entirely from carbon fiber and graphene composites, it weighs a mere 1,234 pounds, yielding a staggering power-to-weight ratio that surpasses most hypercars. The cockpit is designed around a single occupant with a Formula 1-inspired steering wheel, sequential paddle-shift gearbox, and fully adjustable pedal box. At approximately $250,000, the Mono R is an uncompromising machine built exclusively for those who view driving as the purest form of automotive art.

The BAC Mono R takes the already extreme single-seat Mono concept and pushes it further into race car territory. With 343 horsepower from a naturally aspirated Mountune engine revving to 8,600 RPM in a chassis weighing just 1,234 pounds, the performance-to-weight ratio is genuinely staggering. Carbon fiber and graphene composite construction represents cutting-edge materials science applied to automotive engineering. The single-seat cockpit with its F1-style steering wheel creates an experience more akin to driving a road-legal open-wheel race car. The sequential gearbox shifts with precision. Practicality is nonexistent by design -- this is a machine built exclusively for the act of driving at the limit. It costs considerably more than the Ariel Atom 4R, but the Mono R justifies the premium with superior materials, more exclusive construction, and an even more focused driving experience.
