Lamborghini Huracan vs Mercedes-AMG E63

What's the difference?

Not just a spectacularly stupid idea made real, the Lamborghini Sterrato is by far the best, or at least most hilarious, of the many Huracan variants the company has produced. 

It makes you feel like a hero, even when you’re going sideways on dirt like a nutter. It could just be my new favourite supercar. 

Note: CarsGuide attended this event as a guest of the manufacturer, with travel, accommodation and meals provided.

The E 63 S fills its niche in AMG's Australian line-up perfectly. More mature than the brand's four-cylinder hatches and SUVs, but not as overbearing as some of its bigger sedan, GT and SUV stablemates. And its ability to seamlessly switch between serene comfort and dynamic performance has nailed the objective for this 2021 update.

Oh yes, it’s pretty interesting, all right, because it breaks new dusty ground for Lamborghini, and its Huracan in particular.

To cope with its intended use, the Sterrato has been raised 44mm higher than the ground-hugging normal version and it’s also had giant, bolt-on style guards attached to make it look a bit wilder.

Also quite noticeable is the huge roof scoop - which renders rear vision from the driver’s seat a complete zero, they may as well throw the mirror away - which has to be there to help the V10 engine breathe.

The side air intakes through which air usually gets to the mid-mounted power plant have been blocked up, because they would have sucked in too much dirt and gravel. 

I’m happy to report the silly looking rally style headlights stuck to the Huracan’s shark nose are optional, although again, no doubt every buyer has gone for them, because they stand out in a crowd.

The Huracan Sterrato has no problem doing that on its own, of course, because it already looks extremely aggressive, and its knobbly, all-terrain tyres finish off that style flourish.

The E 63 S has been massaged for 2021 starting with flatter headlights, AMG's now signature 'Panamericana' grille, and a high gloss black flap across the top of the curved 'Jet Wing' section defining the lower part of the nose.

At the same time, the vents on either end of it are larger and feature twin transverse louvers to guide cooling air to wherever it's needed.

It's all about what AMG calls 'optimised aerobalance' but the form is just as appealing as the function. The characteristic 'Power Domes' in the bonnet dial up the muscle, as do the fat wheel arches (+27mm each side), and 20-inch rims with distinctive aero inserts.

This car's optional exterior carbon package consists of a front splitter, side sills, a flash near the fender badges, the exterior mirror covers, the boot lid lip spoiler, as well as the lower apron around the redesigned diffuser and quad tailpipes.

New, intricately styled LED tail-lights are also flatter, but there's even more going on inside.

A new AMG sports steering wheel features three rounded twin-spokes with new switches on the bottom to control the car's dynamic set-up.

It also picks up a new take on the small touch-sensitive controllers used to adjust the instrumentation and manage other functions like phone calls, audio and the cruise control.

Not sure I'm in love with them at this stage. In fact, the words fiddly, imprecise, and frustrating come to mind.

Nappa leather covering the superb AMG sports seats, upper dash, and door beltlines remains standard, but the show-stopper is the 'Widescreen Cockpit' - twin 12.25-inch digital screens for the MBUX multimedia interface on the left and instruments on the right.

The instrument cluster can be set to 'Modern Classic', 'Sport' and 'Supersport' displays, with specific AMG read-outs such as engine data, gear speed indicator, warm-up status, car set-up, as well as a G-meter and 'RaceTimer.'

To borrow an official automotive design term, it looks schmick. Overall, with touches like open-pore black ash wood trim, and brushed metal highlights, the interior looks efficient but classy, with an obvious attention to detail in the layout and its execution.

Next question, please. You don’t get cupholders, there’s not really anywhere to put your phone and the cabin generally feels as roomy as a phone box that’s been through the wash and shrunk quite badly.

There’s a frunk that can barely hold two small backpacks and that’s about it. If you want practical space, buy an Urus. The Huracan Sterrato is not a practical car, but that’s not part of its design brief.

At just under 5.0m end-to-end the E-Class sits in the upper range of the mid-size luxury spectrum. And almost 3.0m of that is accounted for by the distance between the axles, so there's plenty of space inside.

The driver and front passenger are provided with heaps of room to breathe, and there's a surprising amount of space for those in the back as well.

Sitting behind the driver's seat set for my 183cm (6'0”) position I had more than adequate head and legroom. But access to and from the back is a struggle for full-size adults.

The rear doors open out a long way, but the limiting factor is the size of the aperture, necessitating excessive contortion of the head and limbs to fold in and out of the car.

Connectivity runs to two (power-only) USB-C sockets in the front centre storage bin, as well as another USB-C (for power and multimedia) and 12-volt power outlet in the centre console.

Speaking of the front centre storage bin, it's a decent size and has a padded split lid so it can double as an armrest. There are two cupholders in the front console, a generous glove box, as well as long door compartments with recesses for large bottles provided.

There's a pair of USB-Cs along with another 12-volt socket in the back, sitting under the climate control panel with adjustable vents in the rear of the front centre console. Nice.

The fold down centre armrest incorporates a lidded (and lined) storage box as well as two pop-out cupholders. Again, there are bins in the doors with room for smaller bottles.

The boot offers 540 litres (VDA) of volume, and is able to swallow our three-piece hard suitcase set (124L, 95L, 36L) with room to spare, or the substantial CarsGuide pram, or the largest suitcase and pram combined! There are tie-down hooks to help secure loads, too.

Don't bother looking for a spare of any description, a repair/inflator kit is your only option. And the E 63 S is a no-tow zone.

So, first of all, let's get the price out of the way. At $253,900, before on-road costs, this car's competitive set is a bruising, all-German trio comprising the Audi RS 7 Sportback ($224,000), BMW M5 Competition ($244,900), and Porsche Panamera GTS ($309,500).

And no surprise, it's loaded with all the luxury features you'd expect in this part of the market. Here are the highlights.

On top of the standard performance tech and safety equipment fitted to the E 63 S (covered later in this review), you'll also find: Nappa leather trim (seats, upper dash, upper door cards, and steering wheel), MBUX multimedia (with touchscreen, touchpad, and 'Hey Mercedes' voice control), 20-inch alloys, three-zone climate-control, interior ambient lighting, auto LED headlights (with 'Active High Beam Assist Plus'), eight “energising comfort programs” (with 'Energising Coach'), an 'Active Multicontour' front seat package, the 'Air Balance' package (including ionisation), and keyless entry and start.

Also included are the the 'Widescreen' digital cockpit (twin 12.25-inch digital screens), 13-speaker Burmester audio with digital radio, Apple CarPlay and Android Auto, a panoramic sunroof, adaptive cruise control, a head-up display, augmented reality satellite navigation, 'Parktronic' self-parking, electric front seats, seat cooling and heating front (heated rear), heated front centre armrest, a power-adjustable steering column, auto rain-sensing wipers, a wireless device charger, illuminated door sills, as well Amazon Alexa, etc, etc, etc.

And our test car also featured a couple of tasty options. An exterior carbon package ($7500), and AMG's professional grade ceramic composite brakes ($15,900), for an as-tested price of $277,300.

The Sterrato is powered by a Lamborghini engine that’s on its way into the history books, a 5.2-litre V10 that will die with this, the last variant of the Huracan.

Its replacement will be powered by a V8 hybrid, which will no doubt be more powerful but simply will not sound as amazing.

The version in the Sterrato has been detuned slightly, partly because of the breathing issues - you just can’t get as much air into an engine when it’s driving through its own self-propelled dust storm - and because of its all-terrain tyres, the first ever to be speed rated to 260km/h.

It still makes an impressive, and very loud, 449kW (602hp) and 560Nm, however. I’d describe it as “more than enough”.

That monster engine is matched with a seven-speed dual-clutch automatic and a very, very clever all-wheel drive system.

The E 63 S is powered by the M178 version of the all-alloy 4.0-litre twin-turbo V8 engine used across numerous AMG models from the C-Class up.

Thanks in no small part to direct injection and a pair of twin-scroll turbos (located in the engine's 'hot vee' to optimise throttle response), this all-alloy unit produces 450kW (that's 612hp) from 5750-6500rpm, and 850Nm from 2500-4500rpm.

And as per standard AMG practice for its Vee engines, this car's powerplant was built from scratch by a single engineer in Affalterbach. Thank you Robin Jäger.

AMG calls the nine-speed transmission used in the E 63 S an MCT, which stands for Multi-Clutch Technology. But it's not a dual-clutch, rather a normal auto transmission using a wet clutch as opposed to a conventional torque converter, to connect it to the engine on take-off.

Drive goes to all four wheels via Merc's '4Matic+' AWD system, built around an electromechanically controlled clutch connecting the permanently driven rear axle (with locking diff) variably to the front axle.

So, Lamborghini claims the Huracan Sterrato will deliver a fuel "economy" figure of 14.9 litres per 100km, which seems like a lot, until you consider it probably won't get anywhere near that, if you drive it the way you're supposed to, particularly foot flat and wheels spinning on dirt.

Again, fuel economy is not a core value for this car, nor its buyers.

An 80-litre tank means a theoretical range of around 480km.

Claimed fuel economy for the combined (ADR 81/02 - urban, extra-urban) cycle is 12.3L/100km, the E 63 S emitting 280g/km of CO2 in the process.

That's a pretty hefty number, but in line with this car's proportions and performance potential.

And Merc-AMG has gone to great lengths to minimise fuel use. As well as the standard 'Eco' stop-start function, in the 'Comfort' drive program cylinder deactivation becomes active, the system able to drop four cylinders anywhere between 1000 to 3250rpm.

There's no physical hint of half the cylinders leaving the party. The only clue is a blue icon on the dash indicating a temporary shift to V4 operation.

Despite all that effort, however, we saw a dash-indicated 17.9L/100km over a mix of urban trundling, highway cruising, and some spirited dynamic assessment.

Recommended fuel is 98 RON premium unleaded (although it'll run on 95 at a pinch), and you'll need 80 litres of it to fill the tank. That capacity translates to a range of 650km according to the factory claim, and 447km using our real world result.

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?

AMG's major goal with this upgrade of the E 63 S was to maintain its dynamic response and ferocious performance, but dial in the extra comfort customers had said they wanted.

So, the 4Matic+ AWD system has been fine-tuned for more smoothness as has the Comfort option in the dynamic set-up. But we'll investigate that shortly.

First, that 4.0-litre turbo V8 in the nose is claimed to slingshot this roughly 2.0-tonne sedan from 0-100km/h in just 3.4 seconds, and it feels every bit that fast.

With 850Nm available from 2500-4500rpm and nine gear ratios to help keep you operating in that Goldilocks band, mid-range thrust is monumental. And thanks to the bi-modal sports exhaust it sounds beautifully brutal.

The nine-speed auto's wet clutch, as opposed to a conventional torque converter, is designed to save weight and optimise response. And while some will tell you an auto with one input shaft is never going to be as fast as a dual-clutch with two, shifts are rapid and direct. The wheel-mounted shift paddles are larger and set lower, as well.

The AMG 'Ride Control+' suspension with multi-chamber air suspension and adaptive damping is amazingly good. The underlying set-up is by multi-links front and rear, and despite riding on big 20-inch rims wrapped with low-profile, high-performance Pirelli P Zero rubber (265/35 fr - 295/30 rr) the Comfort setting is incredibly... comfortable.

Slip into 'Sport' or 'Sport+' and the car immediately feels tauter but far less compliant and forgiving. An impression reinforced by the engine, transmission, and steering shifting to a more buttoned-down mode at the same time.

The standard dynamic engine mounts play a big part here. Able to make a soft connection for maximum comfort, but switch to a rigid link when required.

But no matter which mode you're in, the car is well damped and feels beautifully balanced in quick cornering. And the E 63 S's electro-mechanically-assisted variable-rate steering is progressive, feelsome, and accurate.

The 4Matic+ AWD system is built around an electromechanically controlled clutch connecting the permanently driven rear axle (with locking diff) variably to the front axle.

Torque distribution happens imperceptibly, the big V8 putting its power down emphatically, with various electronic systems tieing up the loose ends as you aim up for the next corner.

 There's even a 100 per cent RWD Drift mode available in the Race setting, but without a race circuit at our disposal this time around that'll have to wait for another time.

The optional ceramic brakes feature huge rotors and six-piston front calipers, and stopping power is immense. And the good news is they operate quickly but progressively at normal pottering around town speeds. No warming up required to get them in an optimal temperature zone (as can be the case with other ceramic set-ups).

The three-pointed star's white-coated boffins have gone to town on the E 63 S, and the car is as good as it currently gets in terms of active and passive safety technology.

You could argue this car's dynamic ability is its strongest contributor to crash-avoidance. But a broad suite of features, specifically designed to keep you out of trouble includes, forward and reverse AEB (with pedestrian, cyclist, and cross-traffic detection), traffic sign recognition, 'Attention Assist', 'Active Blind Spot Assist', 'Active Distance Assist', 'Active High Beam Assist Plus', 'Active Lane Change Assist', 'Active Lane Keeping Assist', and 'Evasive Steering Assist.' That's a lot of assists.

There's also a tyre pressure monitoring and pressure loss warning system, as well as a brake priming function (monitors release speed on the accelerator pedal, moving pads factionally closer to the discs when required), and brake drying (when the windscreen wipers are active the system periodically applies just enough brake pressure to wipe water off the brake rotors to optimise wet weather efficiency).

But if an impact is unavoidable the 'Pre-Safe Plus' system is able to recognise an imminent rear-end collision and fire up the rear hazard lights (at high frequency) to warn following traffic. It will also firmly apply the brakes once the vehicle is stationary to minimise the risk of whiplash injuries if the car's then hit from behind.

If the potential crash is coming from the side, 'Pre-Safe Impulse' inflates air chambers in the side bolsters of the front seat backrest (within a fraction of a second) moving the occupant to the side towards the centre of the car, away from the impact area. Amazing.

As well as that, there's an active bonnet to minimise pedestrian injuries, an auto emergency call function, 'Crash Response Emergency Lighting', even a first aid kit and hi-vis vests for all occupants.

For the record, the current E-Class received a maximum five-star ANCAP assessment in 2016.

The Huracan Sterrato comes with a Lamborghini warranty good for three years with unlimited kilometres.

It also comes with 24/7 roadside assist for an unspecified amount of time. It is also offered with pre-paid scheduled maintenance service for three or five years.

All AMG models sold in Australia are covered by Mercedes-Benz's five year/unlimited km warranty, with 24-hour roadside and accident assistance included for the duration.

Recommended service interval is 12 months or 20,000km, with pricing for a three-year (pre-paid) plan set at $4300, a $950 saving overall relative to its three year, pay-as-you-go 'Service Solutions' capped price program.

And if you're happy to fork over a little more up-front, there's a four-year service deal at $6300, and five years coming in at $7050.
