Ferrari 812 SUPERFAST VS Mercedes-Benz S-Class

Insane. It’s a word that people often lift from their lexicon when describing a supercar experience, because clearly, as forms of transport, things like Ferraris and Lamborghinis are not sane options.

But the Superfast really deserves the word, because it feels not only the opposite of sane, but truly bonkers. As if someone built it for a dare, realised it was a bad and possibly dangerous idea, and then put it on sale anyway.

Picture some tiny-handed child with his greasy, post-cheeseburger fingers poised over a big red button on his desk that could wipe out humanity, and that’s basically the situation your right leg finds itself in when driving the Superfast.

There is so much power on tap here - even the limited amount of it that the engineers allow you to access in lower gears - that it truly seems possible you’ll have a Road Runner moment, and simply dig a hole in the ground, if you push the throttle too hard.

Yes, on the one hand, the noises this extreme V12 makes above 5000rpm are memorable and moving, like Satan himself singing Nessun Dorma in a shower of sparks. At one stage we found a long tunnel, perhaps the only dry road within 500km that day, and my colleague forgot all about his licence and let rip.

The numbers on my 'Passenger Screen' spun like poker-machine wheels, then turned red and then implausible. I was shoved back into my seat as if by Thor himself, and I squealed like a small pig, but my co-driver heard nothing over the Monaco tunnel during F1 sound.

Even on dry road, of course, the winter tyres we were forced (by law) to run in the foul snowy conditions could not maintain grip, and we constantly felt the rear skipping sideways. Fortunately we were in Italy, so people simply cheered us on.

The likelihood that you will lose traction in this car is so high that the boffins have included a special feature in its new 'Electronic Power Steering' system called 'Ferrari Power Oversteer'. When you inevitably start going sideways, the steering wheel will apply subtle torque to your hands, 'suggesting' the best way to get the car back in a straight line.

A proud engineer told me that this is basically like having a Ferrari test driver in the car with you, telling you what to do, and that they used their skills to calibrate the system. You can override it, of course, but it sounds scarily like an autonomous-driving precursor to me.

What’s disappointing about this car having EPS at all, rather than a traditional hydraulic system, is that it just doesn’t feel muscular enough for a hairy-handed monster of a car like this.

It is accurate and precise and pointy, of course, and makes driving the Superfast, even in stupidly slippery conditions, almost easy. Almost.

It’s actually surprising how hard you can push a car like this along a windy and wet mountain road without careering off into a muddy field.

More time, and more traction, would have been appreciated, but you can tell it’s the sort of car you’d grow into, and perhaps even feel in control of, after a decade or so together.

So it’s good, yes, and very fast, obviously, but I can’t get past the idea that it’s all a bit unnecessary, and that a 488 GTB is simply, in every single way, a better car.

But as a statement, or a collector’s item, the Ferrari 812 Superfast certainly is one for the history books.

In former times, as the Germans say, a ‘450' on the boot indicated V8 power. In the W116 S-Class era it was one of the world's most evocative badges when ‘SEL' was also attached.

As mentioned earlier, though, it's the M256 3.0-litre turbo-petrol with a 48-volt ‘mild hybrid' electrical system that's doing the driving, to all four wheels. The real V8 W223 will probably surface later this year or in early 2022 with the S580L flagship. Bring it on.

This is not to say that S450 isn't good enough. With that electrified assistance, the blown straight six is smooth and swift off the line and rapid as the auto seamlessly steps up through all nine gears. Because it's so hushed and refined, it doesn't feel 5.1s to 100 clicks quick, but watching the speedo says otherwise – acceleration is assertive and strong right up way past the legal speed limit.

All that's missing is the burbling soundtrack of a classic Benz bent-eight. Oh well. Outstanding economy is a price we're literally willing to pay in lieu.

Even more impressive is the S450's ability to hustle along mountain roads like an overgrown sports sedan.

Now, for Australia, all S-Classes are fitted standard with an adaptive ‘Airmatic' air-suspension set-up, including air springs and self-levelling tech. In Comfort up to 60km/h, the ride height can be raised by 30mm, or lowered by 10mm under the standard 130mm baseline in Sport at any velocity, while in Sport+ it falls another 17mm.

With that in mind, yes, the standard air suspension performs a magnificent job smothering out most surface imperfections around town. Yet its real other party trick is to tighten up the chassis when corners get interesting and Sport mode is selected. Aided by progressively weighted and reassuringly responsive steering, the Mercedes tips into turns with precision and poise, slicing through with virtually no discernible body lean or understeer.

Now, we're not talking a leisurely drive on rural highways here, but Healesville's famous Chum Creek Road, where even a Porsche Cayman would feel like it's had a strenuous dynamic workout. The S-Class can be hurried along with confidence and finesse, displaying outstanding handling and roadholding for a 5.2-metre long limo. And the fact that the ride quality only suffers marginally when the red horns are out is all the more remarkable.

Back in the cut-and-thrust of inner-city peak-hour traffic, the Benz in Comfort mode continued to reveal its driver-orientated yet passenger-focused twin-personalities, zipping in and out of gaps while remaining comfy and composed inside.

Only when parking in tight spots are you truly aware that the W223 is longer than a Mazda CX-9. The optional four-wheel-steering system is claimed to slash the turning circle to A-Class hatchback levels. 10.9 metres is the claim.

The 2021 S-Class never ceases to amaze and delight.
