The BAC Mono has claimed the production car lap record at the Sepang International Circuit, to the tune of two minutes 14.617 seconds. This makes the Mono just over four seconds quicker around the 5.5 km circuit than the previous best of two minutes 18.997 seconds, which was set by a Porsche 911 GT2 RS.

The Mono – short for monoposto or single-seater – had previously set lap records at circuits including Zolder, Hungaroring and Anglesey, while it was also the quickest road car to take part in the Goodwood Festival of Speed hillclimb. The outright lap record is held by the Mercedes-AMG F1 W08 EQ Power+ driven by Lewis Hamilton in qualifying for the 2017 Malaysian Grand Prix, with a one minute 30.076 second lap for pole position.

To recap, the BAC Mono is powered by a 2.5 litre engine producing 305 hp at 8,000 rpm via a six-speed sequential manual gearbox. Tipping the scales at 580 kg, this gives the single-seater a power-to-weight ratio of 526 hp per tonne. This was a development over the original car, which featured a 2.3 litre engine producing 285 hp.

Named in abbreviation of the Briggs Automotive Company, the BAC Mono first emerged in 2011, and in the earlier, relatively more modest guise, managed a claimed 0-100km/h time of 2.8 seconds, 0-160 km/h in 6.7 seconds and a top speed of 273 km/h. In the vein of specialised track cars, the Mono features a fixed drivers seat for safety and optimum weight distribution, while the steering and pedal box are adjustable to fit.
