This 2023 BAC Mono R is powered by a Mountune Racing-built 2.5-liter inline-four linked with a Hewland FTR six-speed sequential gearbox and a Powerflow limited-slip differential. Purchased new by the current owner, the car has 700 miles in addition to carbon-fiber composite bodywork finished in Lizard Green with exposed gloss carbon-fiber accents over a TIG-welded seamless tube steel chassis. Additional equipment includes a titanium exhaust manifold, adjustable Öhlins dampers, carbon-ceramic brakes with AP Racing calipers, 17″ OZ Racing carbon-hybrid wheels, centrally mounted headlights, a Formula 3-style air intake pod, a rear spoiler and diffuser, a single-seat trimmed in black upholstery, a multifunction steering wheel on a quick-release hub, a cockpit-mounted electrical cutoff switch, and a Sabelt safety harness. This Mono R is now offered on dealer consignment with a color-coordinated Bell/BAC Design helmet, service records, and a clean California title listing the car as a 0000 SPCNS.

The Mono R was introduced at the 2019 Goodwood Festival of Speed and features graphene-enhanced carbon-fiber body panels, a Formula 3-style air intake pod, and a pair of headlights mounted under a plexiglass cover in the nose of the car. The car is 20mm lower and 25mm longer than the standard Mono and has a curb weight of 1,224 pounds, a savings of over 50 pounds compared to the standard model.

The bodywork on this example is finished in Lizard Green with a stripe pattern that reveals gloss carbon fiber on the bodysides and tail, and it is wrapped around a TIG-welded seamless tube steel chassis with a carbon-fiber crash box. Equipment includes front and rear towing eyes, LED running lamps, dual side-view mirrors with body-color caps, and a rear spoiler and diffuser.

The 17″ OZ Racing carbon-hybrid wheels are finished in silver with exposed carbon-fiber accents, and they are mounted with 205/45 front and 255/40 rear Pirelli P Zero Trofeo R tires. The pushrod suspension utilizes billet aluminum uprights, Eibach springs, adjustable Öhlins dampers, and front and rear anti-roll bars. Stopping power is provided by four-piston AP Racing calipers over carbon-ceramic discs at all four corners.

The single-seat cockpit is trimmed in black microsuede upholstery with white stitching. Equipment includes an electrical cutoff switch, a brake bias adjuster, and a Sabelt safety harness.

The 290mm Mono R-branded carbon-fiber multifunction steering wheel features an LCD display screen and hand controls, and it is mounted on a quick-release hub. The digital odometer shows 700 miles.

The 2.5L Ford Duratec-based inline-four was built by Mountune for the Mono R, and it acts as a semi-structural component. Components include a billet crankshaft, a ram-air intake system, dry-sump lubrication, and a gas-flowed cylinder head. Output is factory rated at 343 horsepower, a 35-horsepower boost over a standard Mono.

Power is sent to the rear wheels via a six-speed Hewland FTR sequential gearbox, an AP Racing clutch, and a Powerflow limited-slip differential. The central-exit exhaust system features a titanium four-into-to into-one manifold. Carbon-fiber panels are fitted underneath.

A California BAR sticker is present.

A color-coordinated Bell/BAC Design helmet is included in the sale.
