Summary
Mercedes-Benz AMG GT
"A racing car with street legal approval". Those are the words Mercedes-AMG uses to describe its GT R Coupe.
And even though I'm a forty-something, professional motoring journalist who's well aware of marketing speak when he reads it, the 15-year old in me was jumping around whooping and shouting: "Key! Gimme key to race car" at the launch of the updated Mercedes-AMG GT coupe which also included time in the more sedate GT C.
Well, that's like calling a Tiger Shark more sedate than a Great White, because the GT C still packs more than 400kW (550hp).
As will be the case with most buyers, my time in the Mercedes-AMG GT was spent entirely on the road, the closest we came to a racetrack was driving through Kilmore, and that one was for horses.
This was perfectly fine because you'll want to know just what these beasts are like to pilot on regular roads... roads where surfaces are far from perfect and the posted limits are hundreds of kilometres below the top speeds of these cars.

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?

Verdict
Mercedes-Benz AMG GT8.1/10
The AMG GT is better than a race car for the road because it offers all the comfort and luxury that is completely absent in a track car, yet retains superb dynamic ability – particularly the GT R.
As for the sweet spot, that's easy. The C Coupe offers the best of the S and R from a comfort and handling perspective, while being super quick for less money that the top grade R.
If you could have any of them, which Mercedes-AMG GT in the line-up would you pick? Tell us what you think in the comments below.
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.
Design
Mercedes-Benz AMG GT10/10
There is nothing not interesting about the design of the AMG GT with its long bonnet and low, wide stance. The look is not as dramatic as the SLS AMG, which went into retirement five years ago, nor does it have that supercar's 'gullwing' doors. But there's a clear family resemblance to it and also the iconic 300SL beauty from 1954.
If anything, the AMG GT is a meaner and sharper looking beastie, but still dripping in exotic styling with the hungry looking 'Panamericana' grille flanked by hornet eye headlights and enormous wheel guards that push up into the bonnet to form pontoons over which the driver peers.
It's hard to tell from the images if the AMG GT is big or small, but the dimensions don't lie. The AMG GT is 4551mm end-to-end, 2007mm wide for the GT R and GT C but 1939mm for the GT S (and between 1260mm and 1288mm tall depending on the grade, making it fairly long, wide and short in stature.
There are three grades to choose from - the GTS, GT C and GT R – which all come as coupes, while only the GTC is available as a soft-top roadster, as well.
I can't think of a convertible which doesn't look better with the roof down than with it up and the GT C is no exception to this rule. The open top suits this cruiser's look perfectly.
Telling the three grades apart is easy if you know what to look for: the GT S is a 'narrow body', the GT C has wider rear guards and the GT R has wide rear and front guards.
From behind there's a smoother rear treatment to the S with no wide black vent between the tail-lights, while the GT C has vents behind the rear wheels and the GT R has the most aggro look with the giant diffuser and a central tailpipe.
Exterior styling has stayed the same save for the new LED headlights, wheels and paint colours, but it's the cabin where most of the design changes have taken place.
There's the new steering wheel with drive mode dials and a redesigned centre console with buttons configured in a V-shape which according to Mercedes-AMG is a nod to the V8 engine.
I'm not convinced by the restyling of the console, which didn't suit me ergonomically. It seems to centre around the two cupholders, places the shifter awkwardly rearwards of the media controller and puts the traction control button directly under the driver's elbow. The black piano plastic in the GT R also became smudged with fingerprints quickly.
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.
Practicality
Mercedes-Benz AMG GT6/10
All AMG GT Coupes and Roadsters have two doors and two seats. If you need seating for more there's the AMG GT 4-door which can fit five adults (well, four comfortably) and competes with the Porsche Panamera.
So, if it's just you and a significant other you'll be happy to know the AMG GT cockpit is spacious and even at 191cm tall and with the same wingspan I had more than enough head, shoulder, elbow and legroom.
Cabin storage is limited to a pair of cupholders, a small centre console bin and door pockets just wide enough for a small bottle of water.
Boot space in the Coupe is 175 litres and 165 litres in the Roadster. That was just enough room for the two airline overhead luggage-sized wheelie bags belonging to myself and co-pilot.
As for charging and power on board there are three USB ports and one 12-volt outlet.
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.
Price and features
Mercedes-Benz AMG GT8/10
The entry point into the three model range is the GT S Coupe with its $311,142 list price.
Stepping up to the GT C will cost $329,843 for the Coupe and $355,242 for the Roadster, while the GT R king of the castle commands a list price of $361,042.
Standard features on the S include nappa leather upholstery, heated and power-adjustable seats, AMG Performance steering wheel, panoramic sunroof, 10-speaker Burmester sound system, a 10.25-inch touchscreen with sat nav, Apple CarPlay and Android Auto, 'Mercedes Me' connect system, a 12.3-inch virtual instrument cluster, LED headlights, plus alloy wheels (staggered 19-inch at the front and 20-inch at the rear) with a matt black finish.
You'll see all these S features on the GT C along with more in the form of AMG Performance seats, AMG Performance steering wheel clad in 'Dinamica' microfibre, heated and ventilated seats and staggered 19-/20-inch alloys in titanium grey.
The GT C Roadster has identical features but adds a neck heater, which works surprisingly well.
The GT R comes with the GT C's features and brings its own in the form of the AMG 'Interior Night' package, a carbon-fibre roof, static rear wing and yellow brake calipers.
Porsche's 911 GT3 is a good rival for the AMG GT R, but undercuts it by about $35K, while a Jaguar F-Type SVR is $297,242 and Audi's R8 tops out at $425,500 for the Spyder.
So, is the AMG GT good value? Sure is, when you consider what you're getting relative to what the competitors are offering.
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.
Under the bonnet
Mercedes-Benz AMG GT9/10
All AMG GTs have a 4.0-litre twin-turbo V8 with three states of tune: in the S it makes 384kW/670Nm; in the C it produces 410kW/680Nm; while the output in R is 430kW/700Nm.
A seven-speed dual-clutch automatic transmission is used in all three grades.
All three grades have top speeds of more than 300km/h (318 in the R Coupe; 317km/h in the C Coupe; 316km/h in the C Roadster and 310km/h in the S Coupe) and 0-100km/h times of less than four seconds (R -3.6s, C - 3.7s, S - 3.8s).
Before you start wondering why the R costs $30K more to go one kilometre per hour faster than the C we need to talk about the hardware under the cars that makes the top-grade AMG GT worth the extra money in the section below.
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.
Efficiency
Mercedes-Benz AMG GT7/10
This might surprise you, but the official combined fuel consumption of the AMG GT S is 9.5L/100km, while the GT R's is 11.4L/100km, and the GT C's is 11.5L/100km.
The best combination of driving over motorways and country roads for me on this launch was in the GT R, and after a couple of hundred kilometres the trip computer told me the car was using an average of 12.9L/100km.
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.
Driving
Mercedes-Benz AMG GT9/10
The only grade missing at the launch of the updated AMG GT was the S Coupe. So, while I'm sure it's darn good, I can really only comment about the driving experience of the R Coupe and the C in Coupe and Roadster forms in which we devoured hundreds of kilometres.
First, the R and C both have unique characters that go beyond just differences in horsepower.
The GT C uses the front axle set-up of the GT S with its aluminium double wishbone suspension, anti-dive, coil springs and stablisier bar offering a more supple and cushioned ride, and combines this with the rear axle of the GT R with its rear-axle steering and more pinned down dynamic focus.
The GT R's front axle is also aluminum double-wishbone but comes with braking torque support, mechanically stepless adjustable coil springs, adaptive dampers and an anti-roll bar.
So, while the GT C and GT R feel different to pilot, it's not night-and-day different... more early summer morning sunrise, and midday sun beating down different, if you know what I mean.
See, while the GT C feels just as quick, it's a far more comfortable and easier car to drive on course-chip bitumen and pock-marked Australian roads. The ride while rolling on 265/35 R19 rubber at the front and 305/30 R 20s at the rear is surprisingly pleasant.
Country road corners beckoned on our journey out of Melbourne and the GT C Roadster I set out in responded superbly. That front end felt light, soft and but pointable. What was immediately apparent was how wide the car is, and it felt like the GT C needed every millimetre of the narrow Aussie lanes.
Top down there was almost zero air turbulence in the cabin and while I kept an eye out for the scuttle shake that can come with a convertible, I barely noticed anything along those lines with those short thick A-Pillars holding firm.
Also holding firm was the GT C's rear end which squatted and held tight in the corners even with getting on the gas the roadster stayed composed.
Roof up, most road noise was shut out, well it was hard to hear anything over the bellow of that V8.
The GT C Coupe would be my pick of the AMG GT family and not just because of that smidge of extra boot space. The hardtop just bolsters the overall rigidity of the car and made it feel tauter.
The GT R is a step up in price, grunt and dynamic ability, but it's asking for a higher level of commitment in terms of livability.
The ride on its firmer suspension and 275/35 R19 rear tyres and 325/30 R 20 front rubber makes the GT R more brutal than most people would be happy to live with, I think.
But in return you are getting close to that "racing car with street legal approval" positioning, because the GT R is astounding in its balance, handling, grip and the connection it offers with the driver.
Truly engaging and almost wasted on a regular road, but why it's not quite a race car is that the cabin is dripping in luxury from the beautiful and supportive standard seats, to the leather upholstery and digital instrument cluster.
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.
Safety
Mercedes-Benz AMG GT9/10
Coming standard on all AMG GTs is AEB, blind spot warning, lane keeping assistance, traffic sign recognition and adaptive cruise control.
All cars in the line-up come fortified with airbags, including a knee bag for the driver, side bags for the driver and passenger (combined thorax/pelvis bag), front airbags and window bags (Coupe only).
Front and rear cameras and auto parking make life easy, and while there's no spare wheel there is an inflation kit for temporary puncture repair.
A two-seater car the AMG GT doesn't have anchor points for child seats.
The AMG GT has not been assessed by ANCAP or Euro NCAP for its crash safety performance.
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.
Ownership
Mercedes-Benz AMG GT7/10
The AMG GT has a three-year unlimited/kilometre warranty and along with BMW and Audi it's short compared to the coverage offered by more affordable brands.
Servicing is recommended at 20,000km/12-month intervals. Mercedes-AMG offers a three-year plan which costs $3750 up front or you can pay as you go with capped price servicing at $800, $1000 and $2950 for each respective year.
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.
