Lamborghini Aventador

Summary

BMW M4

When it comes to cars, the letters B, M, and W carry huge credibility. But the extra letters and numbers that follow make all the difference.

A second M for example, means the hot rodders in the Munich maker's performance and racing skunkworks have played with everything from the drivetrain, aero and suspension, to the rims, rubber and interior design.

The number sitting next to it then determines whether you're looking at a compact firecracker (M2), fast-lane monster (M5), or bruising family truckster (X6 M). But every now and then some additional letters find their way onto even a BMW M car's bootlid.

In this case, a C and an S are significant additions to the already impressive M4 badge. They stand for Coupe Sport and were famously applied to BMW's achingly beautiful (E9) coupes of the late 1960s and early '70s.

So, with the howling echo of that all-time classic's in-line six ringing in its ears, the new M4 CS stands up as a proper high-performance coupe, pitched against the likes of Audi's recently reborn RS 5, the Lexus RC F, and Merc-AMG's soon-to-arrive C 63 S Coupe.

Lamborghini Aventador

Too fast, too loud, too crazy, too dangerous, too big. All of these are phrases a supercar lover would never think to utter when considering the sanity-defying existence of the new Lamborghini Aventador S, and yet exactly the kind of things any reasonable person might say after driving one, or even witnessing it in motion.

Too much, clearly, is never enough in La La Lambo world, and it's certainly true that if you desire a car that will puncture your eardrums while rupturing your spleen and bruising your heart, this is the perfect vehicle for you.

Five years after its launch, the Aventador has been updated and upgraded - with new rear-wheel steering, an allegedly improved gearbox, tweaked styling and a button that says EGO - and uprated, with even more power that it clearly wasn't crying out for.

We went to Phillip Island to drive it around a high-speed track covered in rain, mist and suicidal geese.

Verdict

BMW M47.8/10

The BMW M4 CS is every bit as fast and engaging as you'd expect it to be. But be prepared for the day-to-day compromises that go with its pared back interior layout. It's beautifully engineered and dynamically excellent, but will have its hands full when Merc-AMG's similarly sized and priced (updated) C 63 S Coupe arrives shortly to rattle its cage.

Lamborghini Aventador6/10

The Lamborghini Aventador S is a hugely unnecessary car that probably wouldn't exist at all in any sane universe. Fortunately it's from Italy instead.

While it definitely has its flaws - it's simply too big, and too fast, to drive on public roads, and it's too heavy, and mental, to be a purist's track car - there is still something strangely charming about it.

It's the ridiculous design, those super-cool doors, the outrageous and deafening noises it makes, and what it does to your internal organs when you accelerate in it.

There are better, sharper and more affordable supercars than the Aventador S, but there are none that are anything like it.

Design

BMW M48/10

The M4 in either entry-level Pure, or next-step-up Competition spec already looks like John Cena in a 10-year-old's t-shirt, with muscular bumps, curves and cuts extending aggressively in all directions. From its bulbous 'power dome' bonnet, to the pumped-up guards and gaping vents, the M4 screams 'don't argue'.

But this CS version borrows heavily from the track-focused M4 GTS (phased out earlier this year) and dials the aggro up a few notches.

A Matterhorn-sized bulge in the centre of the lightweight CFRP (Carbon-Fibre Reinforced Plastic) bonnet descends towards a broad air extraction vent that could double as a stormwater drain in bad weather.

The front, exposed carbon splitter is a slightly less accentuated version of the GTS's race-ready set-up, and the signature kidney grille is finished in menacing gloss black.

That black finish, part of the standard BMW Individual 'Shadow Line' package, also extends to the side-window trim, window recess covers, and vents on the front wings.

CFRP (unpainted this time) reappears on the roof, and an exposed carbon Gurney flap-style spoiler adds a touch of flash and aero efficiency to the bootlid. A nice match for the carbon diffuser below.

Suitably wide black alloy rims (19-inch front, 20-inch rear) further enhance the intimidating look, with twin LED headlights and an 'Organic rear lighting system', the latter another lift from the GTS, delivering an impressively vivid display.

The interior is familiar BMW territory, but it does feel like you've had a nasty break-up and your significant other has filled the moving van with all the luxury bits.

The leather and Alcantara trimmed sports seats are classy and racy enough, but the door cards are made from a natural-fibre composite BMW calls 'Nawaro'. There are no storage pockets, and you get a webbing strap to help pull the door closed.

Super lo-fi, and bafflingly, the 'armrest' slopes downward at an angle that, despite an Alcantara-trimmed pad, makes it just about impossible to actually rest your arm on it. Perhaps it adds some wheel-twirling elbow room, but for the other 99 per cent of the time it's just annoying.

Although trimmed in contrast-stitched Alcantara, the centre console is also a rudimentary affair, with no storage box between the front seats or adjustable air vents for rear-seat passengers. It might be good for weight saving, but it's not so great in terms of day-to-day practicality (which we'll get to shortly).

There's more Alcantara on the M Sport steering wheel (a leather wheel is a no-cost option) and dash-panel insert, with the CS designation neatly called out in mosaic-style lettering near the centre stack.


Lamborghini Aventador9/10

The lovely and loquacious Italians from Lamborghini showed us a revealing little sketch at the car's launch, which looked a little bit like a bad tattoo but said a lot about their design ethos. It featured mean-looking sharks and menacing cobras morphing with an outline of the Aventador, and was meant to represent the approach to further man-ing up the looks of this S version.

The shark fins are clearly evident in the new and even bigger front splitter, the cobra must be hiding under the engine cover somewhere, while the new rear exhaust shape is apparently modelled on the Space Shuttle.

There are a few touches of the classic Countach, apparently, and plenty of "aerospace" design, which means they've tried to make it look like a fighter jet.

The overall effect is about as over the top as Lady Gaga marrying Ivanka Trump, and yet because its a Lamborghini, you find yourself loving it anyway. Absurdity is their reality. And how could you not fall for any car with those doors?

The interior is not as classy feeling as a Ferrari, but it has a certain brash, flash-cash opulence to it that makes you smile as well.

Practicality

BMW M47/10

When it comes to cars, practicality is a subjective area. The M4 CS offers plenty of space for the driver and front-seat passenger, with room for two more in the back, as well as a decent boot. Practical, right?

But day-to-day details make all the difference and the drive to simplify the CS's cabin and reduce the car's overall weight has seen many common interior-storage options deleted.

The price CS owners pay for racy minimalism is a complete absence of door bins, no lidded box between the front seats, and no oddments tray in the middle of the centre console. Just a pair of cupholders ahead of the gearshift, and a shallow tray beyond that.

If you and a friend get into the car each carrying a standard load of personal junk like a phone, keys, wallet, and a beverage of some description, capacity is immediately exceeded.

Yes, you can shove all that 'stuff' into the (medium-sized) glove box, and that's probably the safer option anyway. But it's not as convenient as slipping things into strategically placed bins and boxes.

In terms of charging/connectivity there's a 12-volt outlet between the cupholders, and a single USB port oddly placed towards the rear of the centre console.

And while there are two seats in the back, getting to them requires the flexibility of a side-show contortionist, and the patience of a Tesla Model 3 reservation holder (the electric system that slides the front seat forward is glacially slow).

Even once you've managed to thread the needle through to the back, headroom is tight, so it's fine for kids and an occasional-only option for grown-ups. There are no cupholders or even a fold-down centre armrest back there, but there is a small, open oddments tray between the seats.

The boot offers a generous 445 litres of space and it's enough to easily swallow the CarsGuide pram or our three-piece hard suitcase set (35, 68 and 105 litres).

A cargo net is standard, there are four tie-down anchors, a small netted storage section behind the passenger side wheel tub, a cubby on the opposite side, shopping-bag hooks and conveniently placed handles, which release the 60/40 split-folding rear seat backs to liberate more room.

Don't bother looking for a spare wheel of any description. A repair/inflator kit is your only option.


Lamborghini Aventador2/10

Yes, the Aventador S is a car, and it will take you from Point A to Point B, although you might leave some of your life expectancy behind on every trip, but other than that, practicality is not a selling point.

It is 4.8m long, just over 2m wide and a mere 1.14m high, the giant Lambo is as thick across the hips as a Toyota LandCruiser, and as pleasant to climb in and out of as an iron lung.

It also burns slightly more fuel than a Space Shuttle launch and is virtually impossible to see out of, but owners won't care because every other car will be behind them somewhere, and they'll only be looking out for plate-glass windows to admire themselves in anyway.

There are no cupholders (although apparently you can option them) and there's virtually no room to store anything at all. None of this matters, of course, because if the people who buy an Aventador S want practicality they'll simply choose one of the other 20 cars in their personal fleet.

Price and features

BMW M48/10

In a classic less-is-more (money) scenario, the $189,529 BMW M4 CS cops a decent serving of standard features, but misses out on some of the luxury trimmings included on the next-rung-down M4 Competition ($156,710).

Standard inclusions run to adaptive LED headlights (including 'BMW Selective Beam' anti-dazzle tech), adaptive M suspension, combination 'Merino' leather/Alcantara seat trim, Alcantara-wrapped 'M' sports steering wheel (with blue/red stitching), a configurable head-up display, a 'BMW Individual' Anthracite roofliner, 'Comfort Access' (keyless entry and start), plus the 'iDrive6' multimedia system (managed via controller, touch or voice) running through an 8.8-inch, high-definition screen.

There are also big 10-spoke forged alloy rims, front-seat heating, sat nav, automatic headlights, rain-sensing wipers, front and rear park distance control, 'Surround View' parking assist, and the 'BMW ConnectedDrive' suite ('BMW Connected+' smartphone app, real-time traffic info, concierge services, and more).

That's a heavyweight equipment list for a car that's all about lightness. Inside, besides the basic door and centre console arrangement, the other significant concessions to kilo stripping are a 'specially adapted' 12-speaker version of Harman/Kardon's 'Surround Sound' audio system with DAB+ digital radio (16-speaker in the Competition), and a simplified, single-zone climate control set-up (dual-zone in the Competition).

Kind of like the CEO wearing a Swatch watch; they're wealthy and powerful, but 'all about performance', so they wear a functional, conspicuously un-flashy timepiece. They still live in a $10m penthouse apartment, though.


Lamborghini Aventador7/10

On the one hand, the $788,914 price for this new S version of the Aventador (the S stands for "Something that is better" according to the Italians) is problematic, and slightly ridiculous, because it seems a lot to pay for a car that would have you shot on sight on suspicion of speeding by the Victorian Police and is about as well suited to Australian conditions as an igloo.

On the other hand, which is covered in thick gold rings with a fat Rolex attached to its wrist, it makes perfect sense, because its vast and silly size perfectly complements the very nature of the car, which is perhaps the biggest 'look at me, I'm rich' statement short of sky writing your bank balance.

The sort of person who buys a car like this, rather than the cheaper, far more sensible and, frankly, enjoyable Lamborghini Huracan, actually wants to pay a lot of money, because it's part of the fun.

Sure, that price only gets you two seats but they're very sexy ones, and truly grippy to sit in, which they need to be in a g-force monster like this.

There's only one spec for an S buyer, and it includes little treats like Apple CarPlay, but if you want the telemetry system, to record your lap times, it's an optional extra, at $3400.

The one feature every owner will want to show off, though - aside from the obvious ones like the scissor doors and 'Bombs-away!' starter - is the EGO button. This is basically a fourth setting to add to the car's existing Strada (Street in Italian), Sport and Corsa (Race) options, but confusingly, because it is entirely personalisable, it actually offers another 24 settings when you press it.

Sure, it's slightly pointless, but at least it's honest, because EGO is what this car is all about.

Each of those settings also changes the Aventador S's lush and wondrous Kombi dash screens (the Lamborghini-styled version of owner Audi's Virtual Cockpit), offering race-car like giant tachometers and even a graphic that shows you which way your wheels are pointing. Not that you'll have time to look at it when exploring your car's 350km/h top speed.

Engine & trans

BMW M49/10

Like its E9 coupe forbear, the M4 CS is powered by an in-line six-cylinder engine, but things have moved on over the last 50 years, and the current (S55) engine offers a mechanical case study in the marriage of high-performance and efficiency.

The all-alloy unit features direct injection and twin turbos, the key drivers behind a stonking 600Nm of maximum torque (50kW up on the M4 Competition), available from 4000-5380rpm, and peak power of 338kW (+7kW), arriving at 6250 rpm.

It also features a 'charge air' (air-to-air) intercooler, 'Double Vanos' variable cam timing, and 'Valvetronic' variable valve lift (inlet and exhaust side).

The sleeveless cylinders use 'Electric Arc Wire Spray' technology to form a thin coating of iron on the cylinder walls, to save weight (no cast-iron liners) and reduce manufacturing complexity. And the engine's closed-deck design increases the block's torsional rigidity, enabling a substantial 10.2:1 compression ratio and use of a lightweight, forged crankshaft.

Transmission is a seven-speed 'M Double-Clutch' (M DCT) dual-clutch auto, complete with dedicated oil cooler, and drive is distributed across the rear axle via an electronically controlled, multi-plate 'Active M Differential'.


Lamborghini Aventador7/10

Let's start with the bad news, which is that the all-new seven-speed ISR (Independent Shifting Rods) gearbox that was supposed to fix the old-tech lurchiness of the Aventador's driveline is still so far off the pace of modern, dual-clutch transmissions that it's mildly embarrassing.

Change gear at speed in this vicious V12 and you're in for a kind of stop-motion, Wallace and Gromit experience. There's no doubt you can feel the aggression of the shifts, but they do remind you of a long-past time when upshifts meant a short break between rushes of acceleration, rather than the seamless shove you now get from a Ferrari (or even a Golf GTI).

Your gear changes can be so violent that they knock the breath out of you, but it could be argued that this merely suits the personality of the car, which in turn reflects the absurdity of its manic engine.

Power has, somehow, been raised by 30kW to an astronomical 544kW at a deafening and ballistic 8400rpm. Lamborghini says the new tune gives even more torque at higher revs, but its maximum figure of 690Nm is actually less than Ferrari's V8-powered 488, which has 760Nm.

The difference is turbochargers, of course, a limp-wristed affectation of a technology that Lamborghini still eschews.

They will tell you it's all about the way the car performs and accelerates, and with a 0-100km/h time of 2.9 seconds (not even a whisker faster than the standard Aventador, which shows you how difficult those times are to improve on), a 0-200km/h dash of just 8.8 seconds, and 0-300 in 24.2, it does do these things well.

What it's really about, though, is the operatic purity and visceral violence of the way the engine sounds, and with its all-new muffler and exhaust system, the S really does take big, shouty showiness to new levels.

Indeed, I would venture this is the loudest road car my ears have ever been assaulted by (a Porsche 918 is louder, but it's really a race car with a rego sticker). Under acceleration it is as eyebrow-liltingly loud as the front row of an AC/DC concert back in the 1990s, but it is the series of explosions you get on the overrun when fear pushes your foot off the throttle that are truly astounding. It sounds like someone throwing steel rubbish bins full of grenades into a cement mixer.

Crazy? Yes. Unnecessary? Yes, but it is wonderful.

It's possible that, as some of my colleagues claimed they could notice, the S is more instantly ballistic when you press the accelerator than the normal Aventador, but frankly that's like comparing being shot with different guns. Let's just say it's a hugely violent, chest-beating engine. And I love it.

Fuel consumption

BMW M48/10

Claimed fuel economy for the combined (ADR 81/02 - urban, extra-urban) cycle is 8.3L/100km, the twin-turbo six emitting 194g/km of CO2 in the process. 

Over roughly 350km of city, suburban and freeway driving (much of it 'enthusiastic') we recorded 10.9L/100km (at the bowser) An impressive number for such a strongly performance-focused machine.

Minimum fuel requirement is 98 RON premium unleaded, and you'll need 60 litres of it to fill the tank.


Lamborghini Aventador3/10

Yes, it sure does consume fuel. Quite a lot, with claimed figures of 26.2L/100km on the urban cycle, and a combined urban/highway figure of 16.9L/100km. Frankly, you'd be lucky if you kept it under 30.0L/100km. It's thirsty work to drive.

Driving

BMW M48/10

Let's get it out of the way. The M4 CS is fast. Anything running 0-100km/h in less than four seconds gains admission to a seriously rapid club, and BMW claims 3.9sec for this car (an exact match for the soon-to-arrive Merc-AMG C63 S Coupe).

We might have given the standard launch-control system a go, and may be able to confirm straight-line acceleration from step-off will compress your chest like an over-zealous lifesaver at CPR practice.

But just as impressive is the in-gear thrust, with 80km/h to licence loss (120km/h) covered in only 3.4sec. Which plays to the twin-turbo six's strength, with maximum torque arriving at a relatively high 4000rpm, and remaining on tap until 5380rpm.

Power doesn't reach its peak until 6250rpm, with the rev ceiling sitting at 7600rpm; impressively high for a twin-turbo engine.

Everything from the DSC, ABS, and active suspension to the active diff, electrically assisted steering and seven-speed, dual-clutch transmission has been tuned specifically for the M4 CS.

The 'M DCT' auto is agreeably civilised at parking speeds, yet shifts positively and rapidly, especially in manual mode, under pressure at higher pace.

An M Sport exhaust system features electronically controlled flaps sitting directly in front of the rear mufflers, and varies the intensity of the accompanying soundtrack according to drive mode and level of aggression. It sounds suitably angry, but those hoping for the soaring purity of say the (S54) naturally aspirated in-line six found under the bonnet of the E46 M3 will be left hankering for the good old days.

Front suspension is a modified MacPherson strut design, with a five-link set-up at the rear, and data from wheel-acceleration sensors on each corner is used to recalibrate each damper's setting every 2.5 milliseconds.

The drivetrain, suspension and steering can each be dialled into 'Comfort', 'Sport' or 'Sport+' modes, and the CS's ride changes markedly in the switch from Comfort to Sport; the former proving compliant and smooth rolling over rough city surfaces, and the latter keeping things reassuringly buttoned down on a B-road blast.

Although BMW says that, unlike the M4 GTS, it has deliberately steered the M4 CS away from a focus on the circuit (no roll cage, no adjustable splitters or spoilers) we'd suggest it's best to keep the Sport+ suspension setting for track days unless you're already planning on replacing some of your older fillings.

Speaking of track days, BMW says the M4 CS's dynamics were “honed on the Nurburgring Nordschleife” where it's recorded a best lap time of 7:38, which is as fast as a Ferrari 458 Italia and Lexus LFA. That's very, very impressive.

At 1580kg the M4 CS is 35kg lighter than the M4 Competition (1615kg), and just five kegs under the Pure (1585kg), so despite all the light-weighting hype it's worth remembering we're still looking at a car tipping the scales at just under 1.6 tonnes.

The electromechanical steering can also be tuned through the three performance modes, and Sport delivers the best combination of quick turn-in, agreeably linear assistance and decent road feel.

But putting the CS's power down out of even moderately quick, tight corners is less convincing. The big forged-alloy rims (19-inch front, 20-inch rear) are shod with ultra-high-performance Michelin Pilot Sport Cup 2 rubber (265/35 front – 285/30 rear).

Squeezing the power in smoothly but quickly, the semi-slick tyres feel like they need more heat in them. Without going anywhere near the DSC's more taily 'M Dynamic' modes, and despite the active diff, the rear of the car will squirm when fed full throttle acceleration on corner exit, unsettling overall balance. Less edgy Michelin Pilot Super Sport tyres are a no-cost option.

The standard M sport front seats look the part (the M4 logos in the backrest illuminate!) and grip firmly without any discomfort for this 183cm tester.

And when it comes to slowing everything down, the standard brakes run to big ventilated discs front and rear, clamped by four-piston calipers at the front, and two-piston at the rear.

Our test example was optioned with the $15,000 'M carbon ceramic' package featuring humungous carbon rotors, thumping six-piston calipers up front, and four-piston rear. For that money you'd expect Le Mans-style braking performance, and while we didn't exactly put them to a 24-hour high-speed test, firm application of the left-hand pedal will consistently stand the car on its nose.


Lamborghini Aventador8/10

Piloting an Aventador around city streets is a challenge, partly because it's like trying to hold a four-metre high, 400kg Rottweiler on a leash, but mainly because it's stupidly wide and you can't see anything from the driver's seat.

Lamborghini has tried to improve the experience of driving it at low speeds with a new rear-wheel steering system, that turns the rear wheels in the opposite direction to the fronts at low speeds, effectively shortening the wheelbase and making it almost liveable in car parks, but then turns them in the same direction as the fronts at higher speeds, for better turn-in and handling.

This was the first time I've ever been fortunate, or perhaps mad, enough to drive an Aventador on a race track, and a fast one at that in Phillip Island, which was covered in a fairly typical Arctic storm front, with enough standing water to attract large, suicidal geese to several corner apexes, including the one at the top of the straight, where the big Lambo was hitting 230km/h before we'd even passed the pits (it had dried out a bit, briefly, for that lap).

With open spaces in front of you, this car delivers the kind of acceleration that forces all the air out of your body, or perhaps you just forget to breathe because your brain is too busy freaking out. It's an invigorating sensation, but not without fear, a bit like jumping out of a plane, and equally addictive.

All that rocket thrust really is its party trick, though, because as mentioned the gear shifts are a bit of a shambles, and the sheer size, and 1575kg weight, of the thing makes it feel like a handful around tight corners.

It's very good around a track for what it is, but what it is is too heavy and too big for circuit driving. Again, you'd have to think a Huracan would be more fun, and would scare you less.

But then it did strike me, on my last lap, as I attempted to find some saliva in my dry mouth, that there's something wonderfully old school, and traditionally Lamborghini, about a supercar that genuinely frightens and intimidates you when you try to push it.

I can't imagine buying one myself, but I can imagine why a certain kind of enthusiast would want to.

Safety

BMW M47/10

The BMW 4 Series (and by extension the M4 CS) hasn't been assessed for crash safety by ANCAP or EuroNCAP, but boasts a solid array of active and passive safety tech, with several notable omissions.

To help you avoid a crash the M4 CS features ABS, brake assist, EBA, EBD, 'Cornering Brake Control' (CBC), Dynamic Stability Control (DSC), Dynamic Traction Control (DTC) and dry braking, 'Emergency stop signal', lane-departure warning and a tyre-pressure-monitoring system.

M4 owners also receive a complimentary BMW Intensive Driving Experience course (one person per vehicle purchase), which is arguably the best crash prevention measure of all.

But significantly, there's no AEB (Auto Emergency Braking) or other, more recent safety bits and pieces (found on other current BMW models) like blind-spot monitoring, forward-collision warning, fatigue detection, reverse collision avoidance, or speed-sign recognition and warning.

If all else fails and a collision is unavoidable passive safety tech runs to head and side airbags for the driver and front passenger, as well as curtain airbags covering front and rear. But again, things like an active bonnet and active front head restraints, fitted elsewhere in the BMW world, are MIA.

There are ISOFIX child-restraint anchors with top tether points in each of the rear seat positions.


Lamborghini Aventador7/10

You're not getting AEB in a car like this, as the sensors would ugly up the front of the car, and there's nowhere to fit them. But you do get a 'passive pedestrian protection system', which is nice.

Some markets get a driver's knee airbag, but sadly we don't, so you have to put up with just four airbags in total, and a collapsible steering column.

Ownership

BMW M47/10

Warranty cover is three years/unlimited km, with 24/7 roadside assistance included for three years, and additional support from BMW 'Servicemobiles' (07:00 – 23:00 every day) staffed by trained techs and stocked with key service parts.

Maintenance on all BMW 4 Series models is controlled by a 'Condition Based Servicing' system which piles real-time data (mileage, time since last service, fuel consumption, and how the car has been driven) into a specific algorithm to determine whether an annual vehicle inspection or (oil) service is due.


Lamborghini Aventador5/10

You can have a five-year warranty with your Italian supercar, but it will cost you $22,200. Or you can have one for four years for $11,600. Both of those seem like a lot of money, but it's the big jump in year five I'd be worried about.
