Summary
Audi TT
When the Audi TT first arrived in 1998 it looked cute… seriously cute, like a car-version-of-a-koala cute. Then over the next couple of decades it grew out of that cuteness into something more menacing looking and the RS versions were well, Google 'drop bear' and you're pretty much on the money.
Now the new TT RS is here looking more grown up and angrier than ever, but does it have the mechanical mumbo to match the aggro appearance? Does it have back seats? Or even a boot? Could you drive one every day without buying your chiropractor a new Porsche? Actually, why wouldn't you just by a Porsche yourself, I mean a 718 Cayman S costs about the same?

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.

Verdict
Audi TT7/10
The Audi TT RS is iconic for its design and should be heaped with praise for its dynamic ability, it's also more practical than many of its rivals offering back seats and a good-sized boot for the class. But despite this latest update the TT RS has fallen behind in advanced safety technology and cabin equipment such as the lack of a media screen.
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.
What do you make of the Z4’s looks - Is it an icon or too far from BMW’s roots? Share your thoughts in the comments below.
Design
Audi TT8/10
Let's start with the looks, seeing as I went on about them so much in the introduction.
This update has seen changes in all the places you'd expect a facelift to cover. There's a new front-end design with a new mesh grille, even larger supercar-like air intakes, a redesigned front splitter and sleeker headlights.
There are also new side skirts, while the rear of the car has more contoured styling and a beefier diffuser.
The tough styling is part of what sets an RS model apart from its more domesticated siblings in the range. There are also the wheels - regular TTs come standard with 18- or 19-inch alloys, the TT RS has 20-inch rims with red RS brake calipers. If you're still uncertain if you're looking at a TT RS then you can be sure you are if it has a fixed rear wing.
Then there's RS engineering which we'll get to in the engine and driving sections. But let's dive into the cabin which has also been updated with a new RS steering wheel, there's the leather RS seats, with the door and console trimmed in leather and aluminum with carbon twill inlays.
The lack of a central media screen means all media, phone and nav menus and displays can only be viewed on the digital instrument cluster. Audi calls this a driver-focused cockpit, I call it marketing spin. I mean a Porsche 911 has a central media screen and you don't get much more of a driver-focused car than that.
I do like the air vents which have the climate control modes within them. I also like that there are back seats – but more on the practicality later.
The TT RS looks bigger in photos than it really is. End-to-end it's only 4191mm long and just 1344mm tall but at 1832mm across it has a wide, planted stance.
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.
Practicality
Audi TT7/10
The TT RS is a four-seater coupe with a hatch tailgate.
I'm 191cm (6'3") tall and there is no way I can sit behind my driving position, but my size is irrelevant here - there's almost zero legroom back there and not even small children are going to have enough space.
Yes, the TT RS isn't a family car, but at CarsGuide we rate all cars for practicality and spaciousness as well as what they're like to drive. That said the TT RS is more practical and spacious than a Porsche Cayman and the BMW Z4 which don't have rear seats at all.
The cargo capacity of the TT RS's boot is 305 litres, which isn't bad at all.
Cabin storage isn't good. The door pockets are small, the centre console bin is only big enough for a wallet but the hidey hole under the dash is useful.
That hidey hole also has a 12V outlet, a USB port and a wireless charger.
This is an obvious point, but the TT RS is low to the ground. The good news is the doors are large and the bubble-like roofline means I never hit my head on the A-pillar as I have with many sports cars.
That roofline also means headroom is good for the driver and co-pilot, although, again, your friends in the rear seat are going to have another reason not to invite you over any more.
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.
Price and features
Audi TT7/10
The TT RS lists for $134,900. While that makes it the most expensive TT, when it comes to horsepower, bang for your buck is excellent compared to Porsche's 718 Cayman S which lists for $140,590 and has 257kW.
The 718 Cayman GTS matches the TT RS's 294kW but costs $172K. That said, the BMW Z4 has 285kW and lists for $127,900 and while Mercedes-AMG doesn't really have a TT RS rival it does have the A45 S with 310kW and a list price of $93,600. Also, in that price range is the Z4's Toyota twin – the Supra with 250kW for $94,536. Don't scoff – it's a superb driver's car.
Let's get back to the TT RS. What comes standard? Features include 20-inch seven-spoke 'matt titanium-look' alloy wheels with red RS brake calipers, RS sport suspension with magnetically adjustable dampers, there's the RS sports exhaust system, privacy glass, leather upholstery, a Bang & Olufsen 12-speaker sound system, wireless charging and 12.3-inch instrument cluster.
The standard RS seats are Nappa leather, the front ones are heated and power adjustable, there's the leather RS steering wheel, proximity key, front and rear parking sensors, Matrix LED headlights and dual-zone climate control.
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.
Under the bonnet
Audi TT9/10
The 2.5-litre five-cylinder turbo-petrol engine in the TT RS is one of my favoruite Audi powerplants and calls the RS 3 and RS Q3 home, too. It's loud, energetic and churns out a whopping 294kW of power and 480Nm of torque. That's enough to get the TT RS from 0-100km/h in 3.7 seconds.
Is the engine in the front or the back? Not such a silly question when you look at the design of the car and you're new to TTs, but the engine is in the front.
Audi's 'S tronic' seven-speed dual-clutch automatic transmission shifts fast sending the drive to all four wheels.
It's not the most powerful engine in the RS model line-up, but I can tell you having driven the TT RS back-to-back with Audi's R8 super car it's one of the most fun powerplants.
You can mash the accelerator pedal on a straight bit of road and not fear that the TT RS will snap and bite you – it's not too much power in that it's controllable with superb all-wheel drive traction.
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.
Efficiency
Audi TT7/10
Audi officially says the TT RS should use 8.0L/100km after a combination of open and urban roads. We'll be able to test that once we have the TT RS in our garage, but either way, that's on the thirsty side.
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.
Driving
Audi TT8/10
Well you already know I love that five-cylinder engine – seriously you could put it in a loaf of bread, and it'd probably be awesome to drive.
Yes, sure the front end in the TT RS felt a bit heavier than I remembered and the nose didn't have that light pick-up-and-point feeling many sports cars have, but on the hill climb section of the test route especially, this coupe was seriously adept through the switchbacks.
Our convoy of test cars included everything from the Audi R8 and new RS Q3 to the RS 7 and RS 6 Avant motherships. And while nothing nails a great road like the R8, the TT RS was eating up the twists while the RS 7 and RS 6 freight trains were struggling with the physics of mass, size, and velocity in those tight corners.
The TT RS felt tight, stable, but agile as it scampered and weaved its way up hills. I'd like the steering to have more feel. Still there's enough feedback through the cabin and the seat to give the driver a good connection with the road.
Is it comfortable to drive? No. I found the standard RS seats too snug for me (to be fair I'm not race-car driver petite), and the ride over the typical Aussie course bitumen and pot-holed country roads made the cabin shake and rattle, along with my bones.
The ride comfort though is what you can expect out of a sports car like this and it's another reason why the TT RS is more than just a sporty coupe with red brake calipers. There's the RS sports suspension with magnetic adjustable dampers, the RS sports exhaust system and big brakes – 370mm discs on the front with eight piston calipers and 310mm discs at the rear which slow things down super quickly.
If you are after something less 'hardcore' there's the TT S or consider the RS Q3 small SUV which has the same five-cylinder engine and can do the 0-100km/h sprint in 4.5 seconds, but has softer suspension for a comfier  ride, while being dynamically impressive in the corners. Oh, and you'll have way more room inside, too. Let's talk about that.
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.
Safety
Audi TT4/10
ANCAP gave the Audi TT a rating of four stars out of a maximum of five when it was tested in 2015. The level of child occupant protection was insufficient for a five-star rating and according to the ANCAP report this was mainly due to the limited space in the rear seat.
There are two ISOFIX points and two top tether anchor mounts for child seats in the second row.
Explore the virtual Audi TT RS
Compared with most new cars the TT RS has a low level of advanced safety technology – there's no AEB or adaptive cruise control, nor is there rear cross traffic alert, but there is blind spot warning and lane keeping assistance.
The TT RS has electronic stability control and ABS, and emergency brake assist (this isn't AEB). The safety features in that sentence haven't been mentioned in one of my reviews in years, and that's because there's not much else for me to list, apart from airbags which only cover the front passengers.
This lack of safety equipment especially for a car which lists for $135K is the reason why the TT RS has scored poorly in this section.
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
Ownership
Audi TT6/10
The TT RS is covered by Audi's three-year, unlimited kilometre warranty which not only falls behind in duration compared to mainstream brands but also its direct rival Mercedes-Benz which now has five-year, unlimited kilometre coverage.
Service intervals are every 12 months or 15,000km with a three-year plan ($2320) or five-year plan ($3420) available.
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.
