Summary
BMW Z4
I remember the first Bond film I ever watched.
I was about eight or nine years old, and it was GoldenEye on VHS. In that film, Pierce Brosnan drove a BMW Z3 convertible, which obviously oozed cool.
I didn’t know at the time that it was just a little bit weird that he wasn’t driving an Aston Martin for the entire duration of the movie, but it didn’t matter, that drop-top Beamer with its radar and missiles imprinted itself on my mind.
As such, I’ve always had a soft spot for BMW’s 'zed' range, so I was quite keen to helm this new one as it came through the CarsGuide office, especially since it shares its underpinnings with the new Toyota Supra.
So, is the new Z4 a case of never meet your heroes? Or did it make me feel a little bit like a secret agent? Read on to find out.

Audi S5
It's inevitable that Audi's S5 will spend the bulk of its time pouncing between traffic lights in Australia's clogged and cramped CBDs, but it's hard to imagine a better place to enjoy the hard-charging antics of this stunning Coupe than the sublime twists and turns of Tasmania's perfect blacktop.
Based on the also-very-pretty A5 Coupe, the S-stamped version adds a powerful 3.0-litre V6 engine, a quick-shifting eight-speed gearbox and some suspension trickery that glues the sleek Audi to the road surface below.
It's the fastest, most powerful and lightest S5 to date, and it's cheaper than the car it replaces to boot. And better still, we had an entire island neatly wrapped in perfect ribbons of tarmac to put it to the test.
The second-generation version of the S5 Sportback is set to appear in May, while the new S5 Cabriolet will follow later this year. For now, the two-door Coupe will lead the charge.Â

Verdict
BMW Z47.5/10
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.

Audi S58.1/10
The kind of car that pushes back the autonomous argument, the S5 Coupe is a fun and frantic blast from the behind the wheel. Addictively powerful, sharp to steer and with the kind of endless grip that turns a twisting road into your own personal amusement park, the S5 injects a ton of fun into back-country blasts. It might be a touch uncomfortable in the city, but that's a price we're willing to pay.

Design
BMW Z48/10
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.
Audi S59/10
Undoubtedly one of the better looking cars on the road today, the Audi S5 Coupe looks sleek and stunning from every angle.
Viewed front-on, the newly designed single-frame grill (it's now wider and flatter) looks slick and powerful, while a raised bulge in the bonnet (Audi calls it a power dome) hints at the performance lurking beneath it.
Side on, a body crease (so sharp it's like it's been cut with a laser) runs the length of the body, while the 19-inch wheels are perched at the furthest corners. Four burbling exhausts emerging from beneath the boot complete this perfectly painted picture of intent.
Practicality
BMW Z48/10
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.
Audi S57/10
Well, the hint is right there in the name. This might be a touch over 4.6m long, but that swooping coupe roofline eats away at your practicality, especially for rear seat passengers.
Up front, though, it's spacious and comfortable and built for purpose, with terrifically bolstered sports seats and a flat-bottomed steering wheel that's among the best in the business.
Shift to the back, and you'll find two seats (the middle one has been replaced by a weird plastic table), but there is plenty of legroom. Headroom, on the other hand, is a less positive story, with anyone who is 183cm (six-foot) or taller are sure to become well accustomed with the S5's roof lining. Â
There's a cupholder in each of the rear doors, matching the two for front seat passengers, and two ISOFIX attachment points in the back row. Backseat riders also get their own air-con controls, and a power outlet.
Boot space is what Audi claims is a class-leading 465 litres (up 10 on the outgoing car) and the rear seat is split 40/20/40.
Price and features
BMW Z47/10
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.
Audi S58/10
Audi's new S5 Coupe arrives with a sticker price of $105,800, which is a touch over its most obvious competitor - the marginally slower BMW 440i Coupe.
The good news, though, is that you'll want for little, and can easily avoid Audi's infamous options list. Expect 19-inch alloy wheels that display the bright red brake calipers, illuminated door sill trims, nappa leather sports seats that are heated in the front, and offer pneumatic bolster and lumbar support, plus carbon detailing in the interior.
In-cabin technology is taken care of via Audi's awesome 'Virtual Cockpit' (a huge digital screen that replaces the traditional dials in the driver's binnacle - the Google Earth-overlayed navigation is particularly outstanding) along with a second, centred screen that feeds a 10-speaker stereo.
Under the bonnet
BMW Z48/10
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.
Audi S59/10
The S5 Coupe's engine is an absolute peach, with a thick and steady flow of power that can make you forget a V8 version ever existed.
The turbocharged, 3.0-litre V6 is good for 260kW at 5400rpm and 500Nm from 1370rpm, channelled through a sensational eight-speed automatic gearbox and on to all four wheels. It's enough for a 4.7sec zero to 100km/h time and a limited top speed of 250km/h. But the sprint is only half the story, with the engine's mid-gear acceleration offering an insanely addictive rush of power when overtaking.
Efficiency
BMW Z47/10
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.
Audi S57/10
Well, Audi puts the number at a claimed/combined 7.5L/100km, but if you drive the S5 anything like you should, then you'll see that number climb skyward like its just been launched into space.
The S5 Coupe's C02 emissions are pegged at 171g/km.
Driving
BMW Z48/10
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.Â
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.
Audi S59/10
Addictive. The power delivery from that S5's V6 is rich and constant, and there's useable urge lurking all over the rev range. The sprint from 0-100km/h is enticing enough, but it's the way the car climbs from 90km/h, 100km/h or 110km/h when you plant your foot, a surging wave of power kicking you in the base of the spine as the S5 Coupe blasts you into the future.
The steering tune is bespoke to the S5, and it's the only model in the A5 range that arrives with adaptive dampers as standard fit, allowing you to dial firmness into the suspension, as well as tightening up the steering, gearing and throttle response.
As a result, it is an absolute joy to pilot through bends, sitting low and flat throughout before making use of its all-wheel drive to hurtle out the other side. It's the stuff involuntary smiles are made of, and you're unlikely to ever tire of it.
For day-to-day use, however, it sits just on the firm side of comfortable, which might grate on pockmarked city road surfaces, but the engine, exhaust and steering weight are all muted enough to ensure it can double as a quiet and composed commuter.
Safety
BMW Z48/10
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.Â
Audi S59/10
Audi has thrown just about everything it's got at the S5 Coupe, and the safety list is extensive. Expect six airbags (dual front, side and curtain), which join a reversing camera, parking sensors, forward collision warning with AEB and pedestrian detection, a rear-impact sensor, cross-path assist and a driver fatigue detection system.
The entire A5 range was awarded the maximum five star ANCAP safety rating.
Ownership
BMW Z46/10
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.
Audi S57/10
The Audi S5 Coupe is covered by a three-year, unlimited-kilometre warranty, and requires servicing every 12 months or 15,000kms.
Audi offers the ability to pre-pay your maintenance costs for the first three years at $1,850.
