But straight-line performance is actually just the Mono R’s warm-up act. And it is nothing, nada, zilchorama, compared with what it can do around corners. And under braking. Especially with a set of Pirelli slicks fitted, which is what BAC are keen for me to try it on most. Why slicks and not the new Trofeo Rs, which is what the R comes on as standard? Although the Trofeos work perfectly well on the road, they aren’t as grippy on a track as the no-longer-available Kumho Ecstas were, apparently, because unlike the Kumhos they haven’t been engineered to work on a car as light as the sub-600kg Mono R. So for circuit work (and for the setting of lap records especially) slicks are the only way to go.
