Mercedes-Benz AMG GT VS Lamborghini Huracan

Nobody will drive the GT63 4Matic+ and think, ‘Oh, this is OK’, because its breadth of performance is phenomenal.

No matter which mode you're in, from Comfort through to track-tuned Race, the Mercedes-AMG blends forceful pace and commanding control without ever breaking a sweat.

Flex your right foot and the two-tonne coupe bounds into action like a giant on a mission, striding past posted speed limit signs in nanoseconds and way, way faster than the law will stand if diligence isn’t exercised.

And there’s no point relying on seat-of-your-pants sensations, either, because the chassis below embraces the road with an almost zealous devotion. Which is astounding, given how agile the four-wheel steering-enhanced handling is.

The 63’s super power is exactly that – it dulls your sense of speed. One tester admitted to exceeding 150km/h before noticing. An odd confession considering the sonic boombox that is the bi-turbo V8’s howl.

But jailbait performance is not even the 63’s most lingering joy. That would be its steering perfection, that delivers that rare trifecta of keenness, crispness and communication. The wheel feels eager and alive in your hands, even when powering between tight turns, backed up by sensational grip and control. How can a two-tonne GT handle so sharply?

Warm, dry roads were the order of the day, so we can’t tell you how the 4Matic+ permanent AWD system deals with wet or slippery surfaces, but the slick multi-clutch transmission, seamless torque-vectoring tech and sticky tyres more than cope with the 63’s formidable outputs.

So, that's the gushing part out the way, then.

Despite the adaptive dampers, rigid architecture and exquisitely sophisticated suspension, the ride is simply too stiff in Comfort mode, and downright jittery on some of the Tasmanian roads we tested on, for the 63 to be considered a true luxury grand tourer. It just isn't comfortable, luxurious or supple enough.

Plus, grippy as they are, the 21-inch wheels transmit too much road and tyre noise through to the cabin, meaning that the GT isn't as quiet as you'd hope. Add the aforementioned trim squeaks, and the expected cocooned silence isn’t always there.

The upshot is that the 63 possesses more of a sports car character than a luxury GT character. Great news if you're a 911 type buyer and are seeking a high-performance 2+2 alternative, but a disappointment if comfort and refinement are priorities.

Still, it is impossible not to be deeply moved by this Mercedes-AMG.

I could give you the short version of what it was like to drive the Lamborghini Huracan Sterrato at speed on a specially prepared dirt race track, which would be to say that I have never, ever had so much fun in a car, but that would be selling it short.

While the Sterrato is clearly built to do one insensible thing brilliantly, while somehow not imperilling the life of its driver, what is most incredible about it is how good it is at everything else, as well.

To create this Huracan, Lamborghini had to increase the ride height significantly, soften up the suspension and increase its amount of travel.

It also had to ask Bridgestone nicely to produce a tyre unlike anything the world has ever seen, an all-terrain tread capable of dealing with dirt and gravel and yet also grippy enough to be used on a sealed race track, or to carve up your favourite mountain pass. 

It also had to be capable of being speed rated to 260km/h, or about 100km/h faster than any all-terrain tyre Bridgestone has ever produced before. 

Looking at the unique Dueler All-Terrain AT002s, with their chunky tread, you would assume that the Sterrato is going to be noisy, slippery and possibly a little rough on public roads, but that’s not the case at all.

This Huracan rides more smoothly - largely thanks to those suspension tweaks - and more quietly than its forebears, and it’s actually more practical around town as well, thanks to the ride height. So, no more flinching at speed bumps.

The tyres also provide proper supercar levels of grip on public roads, even those dusted with a bit of desert sand.

There’s a bit of squirm at the rear and under hard braking, but overall the experience is typically Lamborghini Huracan wonderful, all playing out to a soundtrack that is beyond beautiful from that howling V10.

The first part of our track experience at the Chuckwallah Raceway was also familiarly fantastic, the Huracan ripping around the sealed track at astonishing speed; it certainly doesn’t feel detuned.

Lamborghini had gone to the trouble of mirroring the sealed circuit with a specially constructed dirt track in the infield, so that 50 per cent of our lap would be spent sideways in ankle deep, dust, sand and rocks, much of it through long, long bends, with the occasional chicane set up specially for Scando flicking action.

Now, I am not, by any means, an expert at drifting, nor an accomplished rally driver, so I was, to put it mildly, shit scared of getting this half-million-dollar, limited-edition, 449kW monster on to the dirt section.

I feared I would spin around, or flip upside down, or find some other way to embarrass myself, but what happened when I got there was beyond inexplicable, and beyond joy.

This car is so clever, so easy to drive, so beautifully balanced, that it can turn a total newb into Colin McRae. His name comes to me because the whole experience reminded me of driving a rallying video game, it felt unreal, and yet overpoweringly visceral at the same time.

I could start a drift with the slightest flex of the throttle, then balance the car as it pivoted around a bend before nailing the throttle and haring off to the next fantastic drifting opportunity.

When we got back on the sealed stuff, the car would shake like mad, at 200km/h, as the dust attempted to get its way out of the wheels, but that just added to the excitement. 

The secret wasn’t that I’d somehow become a better driver, it was what Lamborghini engineers call, accurately, “the hero maker”. 

It’s a software and hardware package called LDVI, or 'Lamborghini Dinamica Veicolo Integrata', which, when you put the Sterrato in 'Rally' mode, uses many sensors combined with torque vectoring and selective braking to keep you going where you want to go, with minimal intervention.

Or at least minimal intervention that you can feel, which makes you feel like a hero.

I kind of understand how it works, but I totally relate to how it makes you feel. Like a genius. And you’d pay $500K for that, surely?
