This 2023 BAC Mono R is powered by a Mountune Racing-built 2.5L inline-four linked with a Hewland FTR six-speed sequential gearbox and a Powerflow limited-slip differential. The car features carbon-fiber composite bodywork that is finished in translucent burgundy paint with an asymmetrical gold livery, along 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 5000 R calipers, 17″ OZ Racing carbon-hybrid wheels, centrally mounted headlights, red-painted side-view mirror caps, a Formula 3-style air intake pod, a rear spoiler and diffuser, a single-seat trimmed in black leather and microsuede upholstery, a multifunction steering wheel on a quick-release hub, a cockpit-mounted electrical cutoff switch, and a Sabelt safety harness. This Mono R was purchased new by the current owner and has 1,100 miles. It is now offered on dealer consignment with a color-coordinated Bell/BAC Design helmet, factory extras, a clean Carfax report, 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 translucent burgundy paint with an asymmetrical gold livery, and it is wrapped around a TIG-welded seamless tube steel chassis with a carbon-fiber crash box. Gloss carbon fiber is visible on the fenders, lower nose panels, air intake pod, and tail. Equipment includes front and rear towing eyes, LED running lamps, dual side-view mirrors with red-painted caps, and a rear spoiler and diffuser.

The 17″ OZ Racing carbon-hybrid wheels are finished in gold with exposed carbon-fiber rims, 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 5000 R calipers over cross-drilled carbon-ceramic discs at all four corners.

The single-seat cockpit is trimmed in black microsuede and leather upholstery with yellow contrast 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 1,100 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-two into-one manifold. Carbon-fiber panels are fitted underneath.

A California BAR sticker is present along with the factory chassis tag, both of which list the VIN SA9AUNCB6PL211018.

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