2021 Audi A5 vs 2020 Audi TT

What's the difference?

Predictably stylish, predictably competent, predictably comfortable. In fact, that predictability is among its only downsides. In short, the updated A5 might not move the needle all that much, but it didn't need much moving in the first place. 

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.

It's gorgeous, the A5. There's simply no disputing it. It's elegant, sophisticated, and above all, restrained. There's no look-at-me chintz here, just clean lines, sharp creases and a shapely figure.

Like its A4 sibling, the A5 has been tickled at the front, with a new-look grille, along with a new headlight cluster with redesigned DRLs, and Matrix LED headlights. 

The four sharp bonnet creases that fan out from the grille lend the A5 a sense of speed, even when stationary, and we love the way the 19-inch alloys fill the wheel arches. It looks polished, premium and athletic. 

Inside, Audi's interior treatment is on-point, from the figure-hugging leather seats to the material choices that span the dash. The big news in the cabin is the inclusion of Audi's new 10.1-inch touchscreen perched above the dash, which isn't just easier to use (in my opinion, at least), but also removes the traditional controls from the centre console. 

It means Audi's already fuss-free cabin is even less cluttered, and it's definitely a change for the better. 

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.

It very much depends on the model you've opted for, with the Coupe compromising backseat space for exterior style. 

The Sportback is easily the most practical of the trio, what with its four doors, comfortable backseat and dimensions that stretch 4757mm in length, 1843mm in width and 1386mm in height, and its 480 litres of boot space.

The Coupe, then, is a two-door design, stretching 4697mm x 1846mm x 1371mm, with 450 litres of luggage space at the rear. It's long, the Coupe, but most of that space is absorbed by the front half of the cabin, wth the backseat reserved for kids. 

Finally, the Cabriolet (which we're yet to test) stretches 4697mm x 1846mm x 1384mm, and will deliver the lowest luggage capacity of the lot, at 375 litres.

Elsewhere, though, the A5 range delivers two cupholders up front, with another two in the centre armrest that can deploy to divide the rear seat. Rear-seat riders also get air vents with their own temp controls, USB charge points (joining the two up front) and bottle holders in the doors. 

For parents, you'll find a pair of ISOFIX attachment points in the backseat, too. 

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.

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.

Two choices here, the slightly tongue-twisting 40 TFSI and  and 45 TFSI quattro, both of which make use of a 2.0-litre turbo engine tuned for different outputs. 

The 40 will serve up 140kW and 320Nm, and pairs with a seven-speed S tronic automatic that shuffles that power to the front wheels. Audi reckons you'll see 100km/h in as little as 7.3 seconds.

The 45, on the other hand, will give you 183kW and 370Nm, pairing with the same auto gearbox, but this time sending power to all four wheels thanks to the quattro system. The 100km/h sprint drops to 5.8 seconds at its fastest.

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.

Audi reckons the 40 TFSI engine will return 6.5L/100km on the combined cycle, and emit 148g/km of C02. The bigger engine increases fuel use to 7.1L/100km, but lowers the C02 output to 163g/km. Both those fuel numbers are taken from the Sportback.

Both engines also get a new 12V mild-hybrid system said to drop fuel use by up to 0.3L/100km.

Fun tank capacity is either 54 litres or 58 litres, depending on the model.

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.

You'd describe the A5's drive experience as evolved, rather than revolutionary, but to be honest, in a vehicle this competent, that's no small thing. 

The hybrid tech is unnoticeable, and so the A5 delivers an on-the-road feel that isn't far away at all from the car it replaces. None are truly fire-breathing, but it feels comfortable and sophisticated, the outside world largely banished from the interior (though the firm-ish ride can send road imperfections into the cabin).

Audi has done a stellar job of making the A5 feel connected to the road below it, and the world around it, without dialling down the comfort factor. The steering, light in its normal setting but firming up as you cycle through the drive modes, is direct, but not twitchy, the ride is firm, but not uncomfortable, the engine (at least, the 45 TFSI we drove on launch) is capable without being ridiculous. 

The end result is a predictably competent drive experience, with the A5 delivering in the areas it should, largely before you even notice. 

The only downside to all of that, though, is that the experience is so predictable, that there are few surprises, positive or negative, thrown in. It can leave you feeling slightly disconnected from the experience, rather than truly engaged.

Now, a disclaimer, we spent limited time in the A5 on launch, so we'll wait until we get it in the CarsGuide garage before making a final verdict. But I'd be surprised if we liked it any less over a longer period.

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.

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.

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.

All Audi's are covered by a three-year, unlimited-kilometre warranty, with servicing required every 12 months or 15,000km.

You can pre-pay your service costs for three or five years, which will set you back $1800 for three years or $2820 for five years.

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.
