BMW Alpina B4 vs Lamborghini Huracan

What's the difference?

You could almost call the B4 S the anti-M4. It's still fast and practical but from a completely different perspective. It's much more a grand tourer than the M4 and even with the Akrapovic exhaust (usually a byword for joyous, anti-social racket), subtle.

For some, the price won't matter because the Alpina delivers what they want - M4-like straight line performance without the histrionics or the uncompromising chassis. And there's also a bit of that perverse exclusivity of the styling that you won't get anywhere else.

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.

Alpina has always had a particular aesthetic that could uncharitably be termed as mid-'80s West German - all set square angles and body graphics. Think David Hasselhoff's Berlin Wall look. The company has never really deviated from adding squared-off body bits to the various BMWs it has rebadged under its long-running agreement.

For the B4S, Alpina adds the signature billion-spoke alloy wheels (only a slight exaggeration), a new front splitter complete with Alpina lettering, a weirdly proportioned boot lid lip spoiler and - not even joking - pinstripes. Like I said, mid-'80s West German. You can still recognise the sleek 4 Series Coupe but perhaps the worst of it is the super-sized, wonky-looking ALPINA B4S on the boot.

Inside is rather more restrained apart from the ill-fitting Alpina plaque under the climate control. Again, it's all 4 Series in here, with the lovely Merino leather liberally applied across the cabin. Less lovely is the wood on the door pulls and console but the door cards have an oddly appealing woven leather which looks and feels good.

Sadly the standard 4 Series steering wheel is along for the ride. There's nothing wrong with it - although the Alpina logo does look out of place - but if I were a product planner, I'd beg for the lovelier M 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.

If you're in the front, you're in luck - it's a comfortable place to be, with plenty of leg and headroom. Down back isn't terrible despite the coupe roofline. The two seats are nicely shaped for maximum comfort and separated by an odd plastic tray. The fold-down armrest has two cupholders.

Front seat passengers score a pair of cupholders (bring the total to four for the car) and the long doors will hold a bottle each.

The boot swallows a reasonable 445 litres, which isn't at all bad.

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.

Well, considering every Lamborghini Huracan Sterrato will almost certainly go up in value and become a collector’s item you’d have to consider them good value, at least in investment terms.

On the other hand, any car with a price tag of $503,949, before on-road costs, sits somewhat adjacent to the word “value”.

That large number has not put enthusiasts off, however, with all 1499 of the limited-run Sterrato Huracans already sold, and a long list of people with their names down hoping that someone gets scared and changes their mind, apparently. 

Our vehicle came with two built-in cameras, which you could operate through the touchscreen to record Tik Tok-length videos of your driving.

This is almost certainly a cost option, but no one could tell us exactly, and all of the cars are already sold, no doubt to people who ticked every single option box.

Oh, and you do get aluminium floor mats. Nice.

A lot of your extra money turns up under the bonnet. These days the 440i packs BMW's slick B58 turbo straight six and the B4S does likewise. The boys from Buchloe in Bavaria (there are certain to be women there, too, I just liked the alliteration) added a pair of Alpina-spec turbos to generate a whopping 324kW and, more importantly, 660Nm. Alpina says 600Nm (the max torque figure of the brilliant M4 CS) is available from 2000-5000rpm, while the full 660Nm is available from 3000 to 4500rpm.

The M4 Pure has 317kW and 550Nm from the S55 straight-six. Just so you know.

Like the 440i but unlike the M4, the B4S employs the dependably brilliant eight-speed ZF automatic found throughout the BMW range.

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.

Alpina quotes 7.9L/100km on the combined cycle and we went through the premium unleaded at the rate of 11.7L/100km. I enjoyed myself, so that's not a terrible result.

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.

One of the key differences between the B4 and M4 is the ride. While the M4 can crash over bumps and generally be a little hard to live with, the crew in Buchloe have gone after a much more plush ride. And in that they have succeeded because the B4 S is a mighty fine cruiser. Bumps are dismissed with a haughty disdain, even Sport + silliness doesn't completely write-off ride quality.

Very impressive too, is the steering. While still not at Lotus Elise levels of feel (few cars are), the Alpina tweaks connect the your palms to the road with more clarity than what you'll find in the 440i or M4. Where the M4 particularly adds too much weight, the 440i is a bit more circumspect in that regard.

And then we come to the engine. The B58 six is a belter, better even than the N55 that preceded it. It's still a 3.0-litre straight six but is part of BMW's modular engine family that starts with a 1.5-litre triple in the Mini and 1 Series. The Alpina-spec turbos are noisier, the Akrapovic exhaust lighter and also noisier. It doesn't have the all-out crackle and pop of an Audi or Merc (perish the thought), but when you're on it, the B4 means business. The 660Nm of torque, available over a wide rev range, delivers a steel fist wrapped in a velvet glove and bubble wrap - the speed builds rapidly but smoothly. 

The approach to the chassis tune seems to be based on the driving talents of mere mortals on normal roads, which is kind of like the 440i. It's terrific fun to drive hard but it's very forgiving and patient. The great thing about it is that you wouldn't think twice about jumping in it for the long haul, so comfortable and quiet is the cabin. The M4 will leave it for dead on a winding road, but that's perfectly fine.

One irritant is the replacement of the admittedly cheap BMW gearshift paddles with weirdly non-tactile buttons. They're not particularly easy to use and, probably worse for a sporty car, unsatisfying. It's an odd detail with which to go off the reservation. Cheeringly, the eight-speed ZF is its usual perfect self, so you don't have to worry too much about manual mode or go old school and use the shifter.

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?

In a V10-engined supercar you’re meant to drive on dirt? You’ve come to the wrong place.

Okay, so there’s no crash rating, and there won’t be, but you do get AEB, driver, passenger, and side airbags along with knee airbags as well as front and rear-specific collapsible areas, reinforcement bars in the doors. Oh, and Electronic Stability Control. 

Alpina offers a two-year/unlimited-kilometre warranty which is a bit behind the times and not in keeping with the price point. Servicing is another matter altogether and you're subject to your dealer's standard charges for servicing.

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.
