Mercedes-Benz AMG GT vs Audi TT

What's the difference?

This is no Lotus, but damn if it ain't a hell of a good time, and proof positive that electrification can enhance the V8 experience, rather than ruin it.

Audi is finally saying hooroo to this model which has made the world stop and stare like I did on that Parisian street all those years ago.

The Final Edition is a fitting tribute to this iconic sports car and I’m glad Audi didn’t go ‘OTT’ and deck it out with gimmicky features. 

At the same time the Final Edition’s big rear wing, blacked out badges, wheels and interior colour coding hint that this is not just any ordinary TT and those that know will know.

Farewell Audi TT, we hope something just like you but probably electric appears to stop us in our tracks again. 

It's a mean, but somehow still sleek, looking beast, this big AMG, but it's also immediately recognisable as a thing of intent.

Up front, there's the huge vertical-slat grille that looks like it drove straight out of a Stephen King novel, a massively domed bonnet, and these vacuum-like side intakes that look like they could suck in stray animals.

Then, at the back, there are twin dual-pipe exits (for four in total), and an automatic wing that pops out of the rear bodywork. And all of that's capped off with these massive 21-inch forged alloy wheels hiding golden ceramic-composite brakes.

Mean, yes, but not quite as aggressive as you might expect the most powerful AMG to date to come across, perhaps.

Inside, it's more subdued again, with the AMG presenting a pretty passenger-friendly space, with all the Benz tech you'd imagine, including the massive screens, and — thanks to its air suspension and drive modes — the ability to tailor the ride to your liking, meaning a comfortable and premium experience, despite the power under your right foot.

The Audi TT’s shape has morphed over the past 25 years from the cute, rounded bubble car that first appeared in the late 1990s to the more aggressively and sleek looking sports car with the sharp creases we see today.

Still, there are the familiar pumped-out wheel arches and, while not as prominent as it used to be, that arching roof and the way it flows down to those tail-lights and stumpy tail remains so true to the original TT.

The TT Final Edition has a more menacing and athletic look than the regular 45 TFSI its based on thanks to the S Line Competition Plus exterior package.

So you’re getting the big fixed wing, an aggressive front bumper, and the 19-inch alloy wheels in gloss black.

There’s a black package, too, which add the decals down the side, the blacked-out badges, the black exhaust tips and black wing mirrors.

My test car’s paint colour was Turbo Blue and you can see in the images of the cabin how Audi matches interior elements in the same colour. The contrast stitching on the seats also lifts the sporty feel into high-end territory.

It’s a simple cabin, though, free from busy buttons and giant screens and the incorporation of climate controls into the air vents is genius. 

If you’re wondering what the TT Final Edition’s dimensions are its 4191mm long, 1832mm wide and 1376mm tall. 

It's not overly practical, given its size, with AMG locking in a four-seat configuration with a fixed rear pew that limits boot space. You can get folding seats, but only as part of an option package.

What you're left with is a vehicle that stretches 5054mm in length, 1953mm in width and 1447mm in height, but that serves up rear seating for only two – albeit very comfortably – and, because of the electric battery and motor being housed at the rear, boot space of just 335 litres.

There is triple-zone climate control, and the rear seating is lounge-like and luxurious, while the up-front space is ample for two full-size riders, too.

There's no spare, with AMG's 'Tirefit' puncture repair system on board.

The Audi TT isn’t going to cut it as a family car, but it’s more practical than a lot of people might think.

First this is a '2+2' sports car meaning those two rear seats are there for the odd occasion when you might need them, because the space back there is limited.

But for most of the time having a place to throw a jacket or extra luggage and not have to ask your co-plot to rest it on their lap will feel like absolute luxury.

Up front head and legroom is good, even for me at 189cm tall. Being a coupe the doors are long and although the car is low I found getting in and out easy.

There’s a pretty clever use of space when it comes down to cabin storage. You’ll find door pockets, a glove box, a covered centre console box and a hidey hole/wireless phone charger in the dash.

Back seat passengers have built-in shelves near their armrests. Surprisingly there are four cupholders - two of which fold out of the dash.   

The boot isn’t huge at 305 litres but you can fold the rear seats down to open up the cargo capacity to 712 litres.

So, compared to its two-seater sports car rivals, the TT is relatively and pleasantly practical.

Audi has taken the $84,000 TT Coupe 45 TFSI quattro and created this TT Final Edition with extra features for a list price of $88,749. 

Here’s what you’re getting. First there’s the 'S Line Competition Plus' exterior package which beefs up the TT’s looks with the big, fixed rear wing and 19-inch Audi Sport wheels in gloss 'Anthracite Black' with red brake calipers.

There’s also the black exterior package which brings the black Audi rings badging, black chunky exhaust tips, black side trims and Audi logo decals.  

Inside there’s Nappa leather S sport seats; an Alcantara and leather flat-bottomed steering wheel with paddle shifters; while the armrests, door handles and the centre console are covered by the 'Leather Package' which includes contrasting stitching.  

Metallic paint is also included as part of the Final Edition’s features. Ours was 'Turbo Blue'.

Much of the rest of the Final Edition’s features are shared with the TT Coupe 45 TFSI quattro and includes a 12.4-inch 'Virtual Cockpit' digital instrument display, sat nav, CD and DVD player, eight-speaker stereo, digital radio, Apple CarPlay and Android Auto, wireless phone charging and proximity unlocking.

Our car had a couple of options fitted - the privacy glass which is $950 and the 20-inch gloss black alloy wheels for $1600. 

Rivals to the TT include BMW’s Z4 which lists for $99,200, and its Toyota GR Supra twin for $87,380, while the Nissan Z Coupe is also part of that sporty coupe club at $75,800.

You might already know this but the TT doesn’t have a central media screen and that can appear odd in a new car world where big screens dominate the dashboard. 

It's not just what's under the bonnet, but what's at the rear axle, too.

But let's start at the front, shall we? Here, a familiar twin-turbo V8 engine lurks, producing a potent 470kW and 900Nm, which is fed through a nine-speed automatic, complete with paddle shifters and several drive modes, including the traction-limiting 'Race'.

But that is then joined at the rear by an electric motor with its own two-speed transmission, and which produces 70kW and 320Nm – or up to 150kW for 10-second blasts under heavy acceleration.

Combine both, and you're tapping into around 620kW and in excess of 1000Nm, enabling a sprint to 100km/h in just 2.9 seconds, and a flying top speed of 316km/h.

The TT Final Edition has the same 2.0-litre, four-cylinder, turbo-petrol engine as the regular 45 TFSI TT Coupe with the same 180kW and 370Nm outputs.

The TT is light, though, at only 1460kg and that grunt is enough to slingshot it from 0-100km/h in 5.1 seconds.

The transmission is an eight-speed dual-clutch automatic which sends drive to all four wheels.

Sure, the TTS has more grunt and the TTRS is nothing short of wonderful with its five cylinder powerplant, but the 2.0-litre engine in the Final Edition feels perfectly suited to what is a fun and engaging sports car.

Fuel efficiency is surprisingly impressive for a vehicle this big and powerful, with Mercedes claiming 7.7L/100km and 175g/km of CO2 on the combined cycle.

Helping that is a the 6.1kW battery, which delivers just 12km in all-electric driving range, but helps reduce overall fuel use.

This AMG is AC power only, meaning you can't recharge using fast chargers, but the brand says its secret trick is its ability to recharge itself using captured kinetic energy incredibly quickly – largely negating the need to plug in unless you want to unlock that EV range – with Merc suggesting that, on a race track for example, the battery will discharge and charge itself continuously as you're lapping.

Audi says that after a combination of open and urban roads the TT Final Edition should use 7.0L/100km.

My own testing took in a combination of the best country roads and worst city traffic and at the fuel pump I measured 10.9L/100km.

But most of my time was spent in 'Dynamic' drive mode with the fuel-saving idle stop system switched off. 

The TT's 55-litre fuel tank means you should have a range of about 785km.

There's a lot of big numbers surrounding the Mercedes-AMG GT63S E Performance, but let me throw another one at you – 245km/h.

That was the high score I saw pop up on its digital speedo as the big and electrified Mercedes flew down the main straight at Sydney Motorsport Park (formerly Eastern Creek), before my courage ran out and my foot found the brake.

That kind of velocity is mind-bending in a vehicle this big, and so is the way that power is delivered, with the AMG's big brain deciding how and when to maximise power from the engine and electric motor to deliver a constant surge of torque that shoves you back, and the GT63S E Performance into the future.

But big acceleration is hardly surprising with that much power. What is a little more impressive is how easy this four-door supercar is to wrestle around a racetrack.

Sure, the feeling-out process is a little more involved, as you figure out how and when you'll feel the weight shifting, and as your brain struggles to compute how what's happening is even possible, but after a couple of laps the AMG settles into an easy, flowing rhythm that, while never feeling light on its feet, also doesn't feels like you're piloting a bus.

At least part of that is down to the wizardry on board, like the 'AMG Air Suspension', the rear-axle steering and the limited-slip diff, all of which combine to make the GT63S feel tighter and sharper than it would otherwise.

But it's also partly down to the prodigious power on offer – perfect corner entry and exits are less relevant when you have a cruise missile strapped to your right foot that doesn't just quickly make up for any driver errors, but shrinks the space between corners to the blink of an eye.

Yes, it's heavy, and there isn't much that's pure about the go-fast experience, but it left an ear-to-ear grin on my face, and isn't that priority one for any new AMG?

How does it drive on the road? That I don't know, as this was a track-only drive day. But we will get one on a proper test soon and let you know.

There are plenty of sports cars out there which are dynamically superb yet uncomfortable to sit in.

But the TT’s cabin is as ergonomic as it is stylish with a great, low sitting position and good pedal feel, a steering wheel that can be adjusted to be just right and still with plenty of space underneath for long legs like mine.

The shifter feels the right distance away, good visibility even out the rear window and plenty of ventilation.  And we haven’t even started driving yet.

The TT Final Edition felt to me how a TT should. Fun. Not overpowered nor brutally firm and not ridiculously loud.

Instead, my drive in the Final Edition, which took me along some of my favourite country roads, was one of the most enjoyable runs I’ve had in any car. 

This is a car which ‘listens’ to you and replies with exactly what you’ve asked for in the way it turns into corners and accelerates out of them, and pulls up when you need it too. 

There’s so much connection to the road, you can hear the sticks and stones flying up into the guards, you can feel the coarse chip bitumen through the steering wheel.

But it’s all so easy, too. The suspension is firm but soft enough that you can drive this daily. The steering is light but still with great feedback. 

Some sports cars leave you feeling exhausted, like you’ve just wrestled a bear but the TT Final Edition just leaves you feeling like you've been on a ride and all you want to do is run back around to line up and get back on it again.

This could be a deal breaker for you. The Final Edition, like all Audi TTs, falls short in terms of safety equipment compared to its rivals.

This third generation TT only managed four ANCAP stars out of a maximum of five when it was assessed in 2015.

This was due to the model not having AEB or lane keeping assistance or rear cross-traffic alert.

The only assistance features it has are blind spot warning and self parking (which is handy). It doesn’t even have adaptive cruise control.

There are two top tether points for child seats in the second row but please be aware that the TT was also scored low by ANCAP for child occupant crash protection.

If you do have children and are looking for something safer but still small and sporty, the BMW 2 Series Gran Coupe or Mercedes-Benz A-Class are excellent choices. 

Something to think about.  

The GT63S E Performance is covered by Mercedes' five-year, unlimited-kilometre warranty, and you can pre-pay your service costs to keep the prices down.

Service pricing for the electrified model is yet to be confirmed.

The TT Final Edition is covered by Audi’s five-year, unlimited kilometre warranty.

Serving is recommended every 12 months or 15,000km and although Audi doesn't have capped price servicing there is a five-year/75,000km plan which will cost about $3000 in total for regular maintenance. Yep, that's $600 per workshop visit.
