Lamborghini Huracan vs BMW Z Models

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 Z4 didn’t make me feel like Peirce Brosnan’s 007. It’s way too serious – a proper gritty reboot. Maybe it’s meant for Daniel Craig. Either way, its brave design makes it one of the best-looking BMWs of recent memory, and it’s a tech- and comfort-fest that the Bavarian automaker should be proud of. I just wish it was a smidge more fun behind the wheel.

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 Z4 is a sight to behold. It’s brave, especially for a BMW, it even betrays the brand’s strongest styling pillars, making its own way with its more horizontal grille design, flat body and curved out rear.

It’s more than that, though. In black, this car looks sinister, brooding. The more you look at it, the more you notice tiny details - the scooped-out sides, or the way the entire rear seems to flick up into the integrated spoiler. I couldn’t get enough of staring at it – it manages to look even better with the roof down.

That’s probably when it hit me. To my eyes, at least, this is the most stunning BMW in years. Sure, the X7 is a sight to behold due to its sheer dimensions and borderline offensive grille, but the Z4 is the opposite. It’s subtle, it hides its details away in its silhouette.

It’s designer, Calvin Luk (an Australian no less), was inspired at least in part by the Z8 – another Brosnan bond car – and you can see the Fisker design reflected in the Z4’s low, flat grille and almost bulbous rear.

Inside, sadly, the Z4’s strong design doesn’t quite play out. There’s no wily Fisker touches here, just a standard set of BMW switchgear. While it all works well, it just dumbs down the Z4’s character.

The big, chunky steering wheel in particular is a let-down. It’s the same wheel that sits in the brand’s X5 SUV, and it feels right there, but not here in a convertible where you’re so close to the ground. A smaller wheel would not only suit this car better, it would make it feel just a smidge more alive. I miss the three-spoke M sport wheel from previous-generation BMW cars.

I do like the dash, which is seemly carved from rhomboid shapes - a theme that rolls into the doors, screens, and vents elegantly. I’m normally not a fan of gloss plastics and chrome touches, but in the Z4 they’re all tastefully applied.

The seats, too, are lovely. I’m not sure about the contrast bright-red leather our car came with, but they’re nice and close to the ground and have excellent trim that you seem to sink into just enough to be comfortable and sporty all at once.

It’s a slick place to be, I just wish it felt less like you were at the helm of an SUV and more like you were driving something that looks this damn good.

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.

The Z4 is a convertible, so it’s naturally compromised on space. As far as convertibles go though, you’ll be hard pressed to find one you can fit more stuff into.

The Z4 is wide - the same width, in fact, as a 5 Series - and this carries into the cabin. There are only two seats, but those seats are wide, and occupants will find themselves with luxurious amounts of airspace for their arms, as well as excellent leather-trimmed and padded surfaces for landing elbows on.

Legroom is also great, as the seats have a surprising amount of rail-travel on them, so that even taller folk won’t struggle to fit their limbs in.

A genuinely impressive characteristic of the Z4 is much head room there it is. Despite its low-slung looks from the outside, the roof towers over my 182cm tall head when I’m inside, so this isn’t one of those convertibles that feels like braking too hard might simply decapitate those above six-foot tall.

In terms of storage areas you get some long but shallow trenches in the doors, a bay with connection ports and a Qi wireless charging pad under the air-conditioning controls, a glovebox (hey, not all convertibles have them) and a trick centre console that houses two deep cupholders inside.

There’s also a netted shelf behind the seats that could fit small bags, and given the length of the cabin, you could even fit laptops and the like behind the seats provided you haven’t used the full extent of the seat’s rearward movement.

The boot is deep, wide and long for a drop-top, and offers a total of 281-litres which is more than some popular hatchbacks. It even offers tie-down points and netting either side. To top it off, the fabric roof folds away into its own compartment, so the boot space is unaffected if you choose to drop the lid.

For a convertible – the Z4 is a practicality wizard.

The Z4 isn’t cheap, but it plays in a field of expensive Deutsche drop-tops. Our car was the mid-spec 30i which comes in at an MSRP of $104,900 (before on-road costs).

For that you’ll get a more highly tuned version of the base 20i’s four-cylinder turbocharged engine, producing 190kW/400Nm, 19-inch alloy wheels, M Sport brakes, Adaptive M suspension, and adaptive LED headlights.

That’s on top of the already impressively-specified 20i’s kit which includes dual 10.25-inch screens – one for the multimedia functions, the other as a digital dashboard, a head-up display, full Vernasca leather interior trim, auto-dimming rearview mirror, power adjustable and heated front seats with memory function, dual-zone climate control, 10-speaker 205W stereo, a Qi wireless charging pad, and adaptive cruise control as part of a marginally upgraded safety package (more on that in the safety section).

It’s a pretty plush set of equipment, although a challenging value proposition as the almost-as-well-equipped 20i starts from $84,900, a full $20k cheaper.

Rivals for this 30i model? You’ve got the soon-to-be-discontinued Mercedes-Benz SLC300 ($102,500), all-wheel drive Audi TT S quattro ($105,661), and, at a stretch, the entry-level Porsche Boxster ($122,960).

Of course, being a premium European car, there is an extensive options list. Our car was fitted with the excellent and probably-worth-the-money M Sport differential ($2400), as well as the rudely priced M seat belts (literally just the M pattern embroidered in - $560!) and interior ambient lighting package (lovely, perhaps not worth $550).

The Z4 is only offered in five colours, three of which – including our car’s Black Sapphire – come at a cost of $2000. The red interior, surprisingly, is a no-cost option.

If you’re keeping track that brings the car you’re looking at here to $110,410. Not cheap, and it doesn’t have six-cylinders - but given its other attributes explored later in this review, the fact that it still manages to undercut an entry-level Boxster is actually reasonable.

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.

Welcome to the age of ridiculously powered four-cylinder turbo engines. Despite a capacity of just 2.0-litres, the engine in the Z4 30i produces a whopping 190kW/400Nm.

That’s probably enough for a car this size. I’m keen to drive the six-cylinder, but surprisingly it seems to offer diminishing returns for extra cylinders offering a 60kW/100Nm power boost for an extra $20,000. Perhaps a six-cylinder is the way to go in a BMW, and given this car’s other seriously sporty attributes, it might be the only way to make it a bit more… fun. More on that in the driving section.

All Z4s are rear-wheel drive, using an eight-speed torque converter automatic. Sorry, no option for a manual this time around.

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.

It’s claimed that the Z4 will drink just 6.5 litres per 100 kilometres on the official combined cycle test, but I found that sticking my foot in occasionally resulted in a slightly more realistic sounding figure of 8.4L/100km.

That’s still a great fuel consumption number for a car like this, and perhaps one of the strongest benefits of having just four cylinders.

A discerning vehicle, the Z4 will drink nothing less than the best-quality 98RON unleaded to fill its 52-litre tank.

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?

A car that looks this good better live up to the promise behind the wheel, right?

For the most part, the 30i does, but it’s a victim of its own performance credentials and luxuriousness.

See, a drop-top should be fun-packed, you should feel close to the road, connected. Sadly, a combination Z4’s excellent suspension and not-so-excellent SUV-like interior separates you too much from the surface below.

An advantage, of course, is the refinement on offer. The Z4 is easily one of the quietest, most refined convertibles I’ve ever driven, but it’s a little too insulated.

I can’t help but feel like it’s all business and no pleasure. It feels a little more like I should be cruising to work on the autobahn and a little less like I should be flinging it around corners on a tight B-road.

It feels almost wrong to drive it in a T-shirt. It’s serious and doesn’t want you to mess around, it wants you to wear a suit and tie.

This grand-tourer style feel is one that will keep a lot of buyers in the premium space happy, but I’m of the opinion that BMW will have that segment well and truly covered by the new 8 Series. If the budget allows.

Regardless, the 30i’s four-cyl engine feels like any six-cylinder would have a few years ago. It’s got a surge to it in the straights that’s quite satisfying, and it responds via the exhaust with an angry tone that makes it feel a little more alive, especially with the roof down.

This feeling was all helped along by our car’s M active differential which simply won’t let the fat tyres at the rear slide unless you’ve got high-speeds and loads of tarmac to play with – for better or worse.

The Z4 also has ‘variable sport steering’ which reacts to the car’s speed and position of the wheels to adjust the input ratio. It’s good when you’re at speed, but the weight and response of the steering can make the Z4 feel bigger than it actually is at lower speeds. 

The suspension is firm, and can be a little bouncy over rough surfaces, but seems well suited to the Z4’s chassis.

Other than those notable characteristics you’ll find that the Z4 is wonderfully tuned in terms of its inputs, everything is slick and smooth, suited perfectly for long meandering drives.

Convertibles and safety don’t often fall in the same sentence, unless its one where a concerned relative is trying to convince you not to buy one.

In any case, the Z4 benefits from four airbags (dual front and dual side), as well as the expected electronic stability controls. That optional M Sport differential will have the added bonus of preventing any unexpected slip and slide at the rear.

On the active side the Z4 gets ‘Driving Assistant’ which includes forward collision warning (FCW), lane departure warning (LDW), rear cross traffic alert (RCTA), and rear collision warning. The 30i grade also gets 'active cruise control with stop & go' which allows for full auto emergency braking (AEB) with pedestrian and cyclist detection. Not on the spec sheet, but apparently present in the car I drove was some form of traffic sign recognition (TSR) and lane keep assist (LKAS).

A nice high-res reversing camera displayed on the massive touchscreen is a welcome standard addition.

Considering the meagre safety specification of most convertible cars, the Z4 30i shines with a half-way decent active safety suite. But you can forget ISOFIX child-seat anchor points. There aren't any. 

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.

If recent quotes are anything to go by BMW is set to stick by its lacklustre three-year unlimited kilometre warranty, as it says its customers simply aren’t interested in five years (or longer) when it comes to warranty coverage.

It’s a shame, as even Volkswagen has upped its warranty to five years, and Mercedes has considered a 10-year coverage plan in the past.

In terms of servicing, there are two fixed-price plans available – the suspiciously cheap ‘Basic’ plan which comes at a cost of $1373 for five years (or $274.60 per year) and the more realistic-sounding ‘Plus’ which costs $3934 over five years (or $786.80 per year).

Like every other BMW, the Z4’s computer tells you when its service time: how often it needs maintenance will depend on how often – and how hard – you drive it.
