The BAC Mono R takes the already uncompromising Mono formula and pushes it considerably further. Limited to just 30 cars worldwide, it is lighter, more powerful and more aerodynamically advanced than the standard Mono, with extensive use of graphene-enhanced carbon fibre, revised suspension and a more highly tuned version of its naturally aspirated 2.5-litre engine. The result is a car that feels even closer to a genuine single-seat racing car for the road.

That is also what makes the Mono R so appealing within a serious collection. Alongside Ferraris, McLarens and modern hypercars, it offers something completely different: tiny, ultra-light, single-seat and entirely focused on the driver. It is less about outright numbers and more about delivering a level of immediacy and involvement that very few road cars can replicate.

This particular example is a UK-supplied, one-owner car and was specified to an exceptional level, with an original list price of £364,137. It is also VAT Qualifying, adding another point of interest for collectors looking for one of the most extreme and unusual modern performance cars available.
