BAC’s limited-edition Mono R has set a new reference lap time at the UK’s Goodwood Motor Circuit. The 343bhp, 555kg supercar lapped the 2.4-mile track in 1:15.03 on road-legal Pirelli P Zero tyres – averaging 115mph during the run.
British racing driver Oliver Webb was at the wheel for the lap, which is a mere 5.12 seconds off the outright official Goodwood circuit record of 1:09.91, set by the Arrows-Ford A11 Formula One car in the recent SpeedWeek Shootout.
R is 38bhp more powerful and 25kg lighter than the standard Mono, resulting in a power-to-weight ratio of 618bhp-per-tonne. The Mono’s 2.5-litre, four-cylinder engine has increased in power by 38bhp for the R version, with the cylinder bore size increased and the billet crankshaft stroke reduced to optimise power and torque delivery, and increase rpm from 7,800rpm to 8,800rpm.
Mono R is the first production car in the world fully incorporating the use of graphene-enhanced carbon fibre in every body panel. Using the revolutionary material enhances the structural properties of the fibre to make panels stronger and lighter with improved mechanical and thermal performance.
The lap record was filmed and timed by Briggs Automotive Company and therefore has not been officially clocked by Goodwood.
