What are the key stats for the engine and transmission?
Let's start with the bad news, which is that the all-new seven-speed ISR (Independent Shifting Rods) gearbox that was supposed to fix the old-tech lurchiness of the Aventador's driveline is still so far off the pace of modern, dual-clutch transmissions that it's mildly embarrassing.
Change gear at speed in this vicious V12 and you're in for a kind of stop-motion, Wallace and Gromit experience. There's no doubt you can feel the aggression of the shifts, but they do remind you of a long-past time when upshifts meant a short break between rushes of acceleration, rather than the seamless shove you now get from a Ferrari (or even a Golf GTI).
Your gear changes can be so violent that they knock the breath out of you, but it could be argued that this merely suits the personality of the car, which in turn reflects the absurdity of its manic engine.
Power has, somehow, been raised by 30kW to an astronomical 544kW at a deafening and ballistic 8400rpm. Lamborghini says the new tune gives even more torque at higher revs, but its maximum figure of 690Nm is actually less than Ferrari's V8-powered 488, which has 760Nm.
The difference is turbochargers, of course, a limp-wristed affectation of a technology that Lamborghini still eschews.
What it's really about, though, is the operatic purity and visceral violence of the way the engine sounds.
They will tell you it's all about the way the car performs and accelerates, and with a 0-100km/h time of 2.9 seconds (not even a whisker faster than the standard Aventador, which shows you how difficult those times are to improve on), a 0-200km/h dash of just 8.8 seconds, and 0-300 in 24.2, it does do these things well.
What it's really about, though, is the operatic purity and visceral violence of the way the engine sounds, and with its all-new muffler and exhaust system, the S really does take big, shouty showiness to new levels.
Indeed, I would venture this is the loudest road car my ears have ever been assaulted by (a Porsche 918 is louder, but it's really a race car with a rego sticker). Under acceleration it is as eyebrow-liltingly loud as the front row of an AC/DC concert back in the 1990s, but it is the series of explosions you get on the overrun when fear pushes your foot off the throttle that are truly astounding. It sounds like someone throwing steel rubbish bins full of grenades into a cement mixer.
Crazy? Yes. Unnecessary? Yes, but it is wonderful.
It's possible that, as some of my colleagues claimed they could notice, the S is more instantly ballistic when you press the accelerator than the normal Aventador, but frankly that's like comparing being shot with different guns. Let's just say it's a hugely violent, chest-beating engine. And I love it.
