For the benefit of our telemetry, Lamborghini fitted the SVJ with a set of the semi-slick Pirelli P Zero Trofeo R tyres it offers as an option.
The car proceeded to record a series of numbers neither the McLaren Senna nor the Porsche GT2 RS were able to match during their own road tests; at least until 90mph, when the £750,000 McLaren begins to gently edge ahead.
The propulsive savagery of this 6.5-litre engine – which turned out 0-60mph in 2.9sec, 0-100mph in 6.1sec and 0-150mph in 13.2sec – is rendered all the more extraordinary by the car’s dawdling, clunky single-clutch transmission; the fact that, at 1770kg, as weighed, the whole show is considerably heavier than the rivals above; and the fact that there is no forced induction.
Admittedly, that last element does eventually tell. Though the SVJ has a torque curve usefully both higher and flatter than that of the SV, its best tractive efforts remain a second or so behind the quickest in this class for the 30-70mph haul in fourth gear – our benchmark for mid-range performance.
And yet it matters not a jot. With that lighter flywheel comes a lack of inertia and scalpel-sharp response for which you would trade seconds of outright performance, let alone tenths. Not that those adequately committed will ever need to. Hold your nerve to wind this fabulously linear motor out to its 8500rpm sweet spot and the SVJ accelerates madly – 60-80mph in second gear is dispatched in a mere 1.3sec – with a soprano howl evocative of F1’s glory days.
Out on the road, this sonic assault, along with the car’s girth, contrives to somehow make it feel even quicker still. Fortunately, the SVJ is not under-endowed in the braking department. Carbon-ceramic discs of 400mm (front) and 380mm (rear) stopped our car from 70mph in 40.8m, and they are easy to modulate at road speeds.
In terms of outright stopping power on a dry surface, the Lamborghini split the Senna (37.4m) and another naturally aspirated V12 Italian whose performance closely resembles that of the SVJ: Ferrari’s 812 Superfast (42.1m).
