Manufactured in Liverpool by the Briggs Automotive Company, the street-legal BAC Mono is a super lightweight single-seater sports car offering unadulterated performance to rival some of the most extreme track-only race cars. The ultimate Mono R version debuted in 2019 equipped with a more powerful 2.5L Mountune Racing engine and lighter graphene-enhanced carbon fiber bodywork lending to an astonishing power-to-weight ratio of 0.461 kW/kg.

he Mono is constructed around a TIG-welded seamless tube steel driver safety cell featuring a carbon fiber crash box and an FIA-compliant rollover protection system. Compared to the original Mono, the R version features revised graphene-enhanced super light carbon composite low-drag bodywork with a 25mm increase in length and a 20mm reduction in overall height. This example is finished in grey with an exposed 2x2 carbon twill. Equipment includes dual mirrors, LED lights, exposed pushrod suspension, an F3-style carbon fiber ram air intake, an integrated rear spoiler, a rear diffuser, titanium tow eyes, dual center-mounted tailpipes, a locking billet aluminum fuel cap, and 17” Dymag carbon fiber wheels dressed in Pirelli P Zero Trofeo R tires.

The driver is provided with an FIA-compliant safety harness and a quick-release 290mm carbon fiber steering wheel with a billet aluminum housing, illuminated switch gear, pneumatic paddle shifters, and a GEMS LDS4 color display. Other features include a remote battery charge socket, AP Racing cockpit-adjustable brake bias, an electronic parking brake, an adjustable AP Racing pedal box, and a BAC-developed cockpit aero screen.

Co-developed with engine partner Mountune, the BAC Mono R is powered by a Ford Duratec-based 2.5-liter inline-four engine with forged pistons and connecting rods, a billet crankshaft, a lightweight titanium 4-into-1 exhaust, and a gas-flowed cylinder head with individual butterfly port throttles. Up to 343 HP is sent to the rear wheels through a lightweight magnesium Hewland FTR 6-speed sequential transmission and a Powerflow limited-slip differential. The suspension includes adjustable pushrod double-wishbone suspension with two-way adjustable Öhlins dampers, lightweight billet aluminum uprights, and Eibach racing springs. Stopping power comes from AP Racing Formula Car 4-piston brake calipers paired with Surface Transforms carbon ceramic discs.
