What's the difference?
Close your eyes for a moment and picture a mountain of pure performance - a towering, glimmering mound of unbridled grunt.
Okay, got it? Right, now open your eyes and look at the pictures of this all-new Audi RS Q8. There are some similarities there, right?
Audi’s first performance SUV in the upper-large segment looks the business. It also looks, if you squint a bit, a little like the Lamborghini Urus with which it shares an engine and platform.
But while the Lamborghini tips the pricing scales at a hefty $391,968, the Audi RS Q8 is a comparative bargain at just $208,500.
So, can you consider it a cut-price Lambo? And is there go to match all that show? Let’s find out.
Driving the first-generation Mercedes-AMG A 45 in 2013 was an intense, noisy, brutal experience and I loved every bone-shaking, ear-bleeding moment of it.
But I’m older now, married and have children, and while this is also an intense, noisy, brutal experience I now prefer cars to be less like a 24-hour, seven-day-a-week continuous cage fight. So, I was surprised to find the new-generation A45 S has grown up a bit, too.
So, like me, is the new Mercedes-AMG A 45 S 4Matic+ not as quick as it used to be, and does it have a dad bod, now, too? Far from it. If anything, it’s matured into the serious weapon of a hot hatch it was always supposed to be.
The Audi RS Q8 is every bit as competent as it is striking to look at - and it’s plenty striking to look at. It surely won’t appeal to everyone, but if you’re in the market for a big, boisterous SUV, the Audi ticks plenty of boxes.
And if you happen to be in the market for a Lamborghini Urus, be sure to drive this before signing on the dotted line...
The Mercedes-AMG A 45 4Matic+ may have grown up a bit in that it’s not as noisy or uncomfortable as the first-generation version which arrived in 2013, But if anything, its more portent than ever. Superb Mercedes-AMG craftmanship, outstanding performance and good value as far as bang for your buck goes.
It looks plenty striking, the RS Q8, especially dressed in the bright green paint work of that harks to its Lamborghini sibling.
There are the massive black-on silver alloys, the bright red brake calipers the size of dinner plates, and the body creases that bulge out over the rear arches like a 1950s’ pin-up model. All of which looks great.
Step around to the rear of the vehicle and you’re greeted with twin exhaust exits bookending a massive textured diffuser, a single light LED that splits the multi-globe LEDS, and the slick roof spoiler.
It’s the front-on view, though, that’s the most imposing, with a black meshed grille that looks as big as a hatchback, two LED-filled slimline headlights and massive side venting.
Climb into the cabin and you’re met by a wall of leather and technology, not to mention a sense of immense space.
Everything is digital and touch activated, of course, and yet it doesn’t feel garish and overdone.
When I went to pick up the Mercedes-AMG A 45 S 4Matic+ I walked right past it and then like that lost and confused John Travolta in Pulp Fiction internet memes, wandered around before asking where the car was.
That’s because I was looking for something with a gigantic spoiler on the roof and probably hi-vis green with stripes. But the car assigned to me was the A 45 S in its standard form, and the styling is subtle enough for it disappear into a crowded car park like James Bond into a lavish dinner party.
But like Bond, chances are the A 45 S is the most hardcore person in the room, it just doesn’t walk in announcing it to everybody.
Look closely and you'll see that the A 45 S is not just another small prestige car. There’s the 90mm quad exhaust poking out of the chunky diffuser, the giant 'Panamericana' grille, and the angry looking front apron.
Then, there are the 19-inch matt black alloy wheels wrapped in low-profile Michelin rubber and enormous brake discs with their red calipers, all barely contained by the pumped up front wheel guards which are much bigger than those on a regular A-Class.
The cost option my test car wore was the 'Mountain Grey Metallic' paint, but if anything it made the A 45 look even more covert.
The cabin is small but luxurious and sporty with two-tone leather upholstery (the red and black 'Lugano' leather in my test car is a no-cost option), there’s the microfibre-clad AMG steering wheel, brushed aluminium trim, metal-trimmed pedals and the large display panel (it’s actually two screens joined) is also standard.
The A 45 S is a hatchback measuring 4445mm in length, 1850mm wide and 1412mm tall. Not keen on a hatch but want something with similar dimensions? The CLA 45 S is the A 45 S’s four-door twin-under-the-skin and is just as much of a weapon.
And if you want your A 45 S to look more aggressive, you can option the 'AMG Aero Package' which will see a giant rear wing fitted to the roof.
Or you can buy the Edition 1 version of the A 45 S which includes the big spoiler and shouty design bits to makes sure everybody knows you’re the assassin in the room.
Very damn practical, actually. Which is no great surprise, given the size of the thing, but still impressive when you consider the performance it can conjure.
It stretches more than 5.0m in length, and those dimensions translate to an absolutely massive cabin, which is actually most noticeable in the backseat, which is gigantic. You can essentially park an Audi A1 back there, such is the space on offer, but you’ll also find two USB ports, a 12-volt power outlet, digital air-con controls and leather as far as the eye can see.
There are two cupholders up front, another two in the pull down divider in the rear, and bottle holders in all doors, as well as ISOFIX attachment points for child seats.
Storage? Well, there’s lots… The backseat slides forwards or backwards to prioritise space for either passengers or cargo, unlocking 605 litres of luggage room, but with them folded flat, the RS Q8 will deliver 1755L of space. Which is a lot.
Along with good performance and handling, part of the appeal of hot hatches is that they’re practical… to a degree. The A 45 S is a small car, but it has four doors, five seats and a boot.
The cabin is small, no doubt about it, but even at 191cm tall I had plenty of room while driving, the seating position is perfect actually, although sitting behind my driving position saw my knees just touching the seat back.
Headroom is getting limited back there, but I still had space. Could you get away with the A 45 S as a family car? I had my family in it for a while, but there’s just the three of us and my son is pre-school-aged. So, a young, small family, yes… until it starts to grow.
Cabin storage is good with two cupholders in the rear centre fold-down armrest along with small door pockets and seat-back nets. Up front there are another two cupholders, giant door pockets, a big split-opening centre console bin and a tray for the wireless charger big enough to fit an iPhone 11 Pro Max.
Boot space is good at 370 litres. The big shiny CarsGuide suitcase fitted in easily (see images) and apart from the wide-opening of the boot, another hatch power of practicality is that you can fold the rear seats down to open up more cargo carrying space, and in the A 45 S’s case that’s 1210 litres.
I’ve mentioned the wireless charger but there are also four USB-C ports (two up front and two in the rear), back seat passengers also have directional air vents, which is another bonus, along with dark tinted windows (welcome when my son was sitting back there in his car seat).
It feels a little strange marking such an expensive SUV so highly for value, but the truth is that, comparatively at least, it’s something of a bargain.
As I mentioned above, the key competitor for a car like this is the Lamborghini Urus (which is Audi’s stablemate) and that will set you back close to $400k. The Audi RS Q8? Almost half that, at just $208,500.
See, it’s a steal! For that money you get an engine that could power a small city and the kind of performance kit required to make a 2.2-tonne SUV go around corners at speed. But we’ll come back to all that in a moment.
You also get massive 23-inch alloys wheels outside, with red brake calipers peeking out from behind, as well as RS adaptive air suspension, a qauttro sport differential, all-wheel steering, electronic active roll stabilisation, Matrix LED headlights, a panoramic sunroof, and an RS sport exhaust.
Inside, you’ll find 'Valcona' leather seats that are heated in both rows, ambient interior lighting, leather everything, automatic sun blinds, illuminated door sills and just about every other piece of kit Audi has in its sizeable grab bag.
On the tech front, you’ll find 'Audi Connect plus' and Audi’s 'Virtual Cockpit', and a 17-speaker Bang and Olufsen 3D sound system that pairs with twin (10.1-inch and 8.6-inch) screens, capping off a seriously tech-heavy cabin.
The new Mercedes-AMG A 45 S 4Matic+ lists for $93,600. Coming standard are the 19-inch matt black alloy wheels, the quad exhaust and chunky diffuser, Panamericana grille and AMG front apron, the red brake calipers, small roof-top spoiler and privacy rear glass.
Inside, the A45 S comes standard with sport seats and tone-tone leather upholstery – there’s ‘Yellow cut’ leather with contrasting yellow top stitching (or in the case of our car the no-cost option of red and black Lugano leather), and an AMG Performance steering wheel clad in 'Dinamica' microfibre.
Also standard is the large landscape display which is actually two 10.25-inch screens; one for the digital instrument cluster and another for the media system.
There’s also Apple CarPlay and Android Auto, sat nav, a Burmester stereo, 'Mercedes Me' (voice recognition) assistant, digital radio, wireless phone charging, power adjustable and heated front seats, dual-zone climate control, ambient lighting, proximity key, LED headlights and a panoramic sunroof.
The only feature I felt was missing was a head-up display, which needs to be optioned.
In the first year of sale (until the end of 2020) an Edition 1 version of the A 45 S will be sold. Listing for $101,690 the limited edition comes with a tougher look thanks to the addition of the AMG aero package which fits the giant rear wing, along with 19-inch twin-spoke matte black alloy wheels, door decals and AMG performance seats. Oh, and it only comes in 'Sun Yellow.'
Rivals to the Mercedes-AMG A 45 S 4Matic+ come in the form of Audi’s RS3 Avant, the BMW M2 or, and this may seem like an odd suggestion, the Tesla Model 3 hatch. The latter is a pure electric vehicle but has a 0-100km/h time of 3.4 seconds and an output of 335kW… just saying.
Sitting under the A 45 S 4Matic+ in the A-Class range is the A 35 4Matic for a list price of $69,300. The A35 doesn’t come with the big Panamericana grille and the 2.0-litre engine has a lower output but still packs an impressive 225kW/400Nm.
The Audi RS Q8’s 4.0-litre twin-turbo V8 produces a monstrous 441kW and 800Nm, sent to all four wheels via an eight-speed triptronic automatic.
At more than two tonnes, it’s a lot of car, but that’s also a lot of power, and so the go-fast SUV can produce a cracking sprint to 100km/h of just 3.8 seconds.
The RS Q8 is also equipped with a 48-volt mild hybrid system that is ostensibly designed to lower fuel use, but is actually more useful at plugging any turbo holes when you really plant your foot.
There may be hot hatches out there which look wilder than the Mercedes-AMG A 45 S 4Matic+ but do they have the most powerful four-cylinder engine ever to go into a mass-produced car? Nope, but the A45 does: it’s a 310kW/500Nm turbo-petrol four.
It doesn’t sound as angry and gravelly as the previous A 45’s engine but it has more grunt (an extra 30kW/25Nm) and is claimed to catapult the hatch from 0-100km/h in 3.9 seconds.
The '4Matic' part of the name indicates the hatch is all-wheel drive and the '+' means it’s a more sophisticated version of the system which allows all of the drive to be sent to one axle, if need be.
What need would that be? The need to drift, of course, which should be up there with other human rights such as clean air, fresh water and free speech.
Yep, the A 45 S comes with 'Drift Mode' (for the racetrack, of course), along with a 'Launch Mode' for perfect-every-time transitions to warp speed.
Changing gears gunslinger-fast is an eight-speed dual-clutch automatic transmission.
For every action there is an equal and opposite reaction, right? Well the reaction to all that power is a whole lot of fuel use.
Audi reckons the RS Q8 will sip 12.1L per 100km on the combined cycle, but we suspect that’s wishful thinking. It will also reportedly emit between around 276g/km of C02.
The big SUV is fitted with a huge 85-litre tank.
Mercedes-AMG says the 2.0-litre, turbo-petrol, four-cylinder in the A 45 S should use 8.9L/100km after a combination of open and urban driving.
My fuel test saw me drive 131km of urban and country roads, plus some motorway sections, and needed 16.9L of premium unleaded petrol to fill the 51-litre tank back to full.
That comes to 12.9L/100km, which is thirsty, but my driving style may have contributed significantly to that high figure.
How do you describe the drive experience of the RS Q8? Utterly, utterly surprising.
I’ll give you an example. You approach the hulking SUV, check out its massive alloys wrapped in performance rubber, and you know - just know - that it will ride like a broken billycart on anything but the most silky smooth of road surfaces.
And yet, it doesn’t. Aided by its clever air suspension (which drops the ride height by 90mm when switching between Off-Road and Dynamic modes), the RS Q8 positively glides ever dodgy road surfaces, stifling lumps and bumps with surprising aplomb.
So then you think, ok, we’re set up for compliance, so this big behemoth will go around corners with all the dynamism of a spilled bowl of cereal.
But again, it doesn’t. In fact, the Audi RS Q8 attacks corners with incredible stiffness, the active anti-roll systems weaving their dark magic to keep the towering SUV straight and true, and with barely a hint of body roll.
The grip is ferocious (we’re yet to find its outer limits) and even the steering feels more direct and communicative than in other smaller, ostensibly sportier Audis.
The result is a tech-heavy spaceship that’s surprisingly easy at slow speeds, and quiet too, even over rough roads. But one that can also activate warp speed at will, leaving smaller cars in its considerable wake on the right stretch of road.
Downsides? It’s not quite willing to pounce off the line. Sure, it makes up for it in the long haul, but there is a noticeable moment of hesitation, almost as though it’s contemplating its considerably weight, before it finally lunges forward.
It’s also so competent, so efficient, that it can leave you feeling a little detached from behind the wheel, or like the Audi is doing the heavy lifting for you.
I wasn’t lying in the introduction to this review. The previous A45 was a pretty intense driving experience. The ride felt brutal, the exhaust note screamed and crackled like somebody had set a wheelie bin full of fireworks alight.
And then there was the sweating. I seemed to sweat a lot driving it and there was nothing wrong with the climate control, that just happens to me when I’m under pressure and excited.
So, has the new-generation A 45 S 4Matic+ gone all soft and quiet on us? No, but things have been toned down a tad.
The exhaust note is not as gruff or loud, and even in 'Sport +' and 'Race' mode it’s still quiet enough to pull into a driveway at night without making enemies of your neighbours.
And the ride is also not as harsh, although even in 'Comfort' mode my wife still found it verging on too firm.
The performance and dynamics, however, felt as sharp as ever.
Acceleration is supercar quick at 3.9 seconds. My gawd, you needed a Ferrari F40 to do that in the mid-’80s, and even now the new Mercedes-AMG GT S supercar gets there only a tenth of a second earlier, and it has a twin-turbo V8.
Top speed for the A 45 S is electronically limited to 270km/h. But hot hatches aren’t really about straight-line speed, they’re more about bent-line speed. You know, corners.
So, I took the A 45 S on the twisty roads I take anything that calls itself sporty. The agility of the A 45 S is outstanding thanks to a rigid chassis that handles a change in direction as quickly and easily as you can turn your head.
The brakes bite hard when they have to, and the all-wheel drive hatch scrambles tenaciously out of corners.
A racetrack is really the best place to truly test a serious sports car's limits and our own James Cleary did just that when he drove the A 45 S at its international launch.
As a daily driver, though, for somebody who occasionally likes to get into it on a curvy road the A 45 S is comfortable enough to live with, but hard enough to remain engaging and dynamic when you get the chance to have a squirt.
The RS Q8 gets six airbags, as well as a host of high-tech safety equipment, with Audi pretty much throwing everything its got at its new performance flagship.
Think adaptive cruise with stop and go, lane guidance assistance, active lane assist, blind-spot monitoring and a 360-degree parking camera. You also get a parking system, pre-sense rear for nose-to-tail collisions, and an AEB system that works at up to 85km/h for pedestrians and 250km/h for vehicles.
There’s also collies avoidance assist, rear cross-traffic alert, intersection crossing assist, and an exit warning system.
Don’t expect Audi to crash an RS Q8 anytime soon, but the regular Q8 recorded a full five stars when ANCAP tested in 2019.
The Mercedes-AMG A 45 S 4Matic+ received the maximum five-star score when it was tested by ANCAP in 2018.
The safety equipment list is impressive. Along with nine airbags and a 360-degree camera there’s advanced safety tech such as AEB with cross traffic function, blind spot warning, lane keeping assistance, lane change assistance, auto parking and adaptive cruise control.
For child seats there are three top tether points and two ISOFIX mounts across the second row. Small hatches are the easiest cars to put top tether seats in thanks to the good access to the hook point. I fitted my son’s car seat into the back of the A45 S without any problems.
All Audi’s are covered by a three year, unlimited kilometre warranty, and require annual servicing. Audi will allow you to prepay the first five years of service costs for $4060.
The Mercedes-AMG A 45 S 4Matic+ is covered by a five-year/unlimited kilometre warranty.
Servicing is recommended at 12 month/20,000km intervals. Servicing is capped at $850 for the first year’s visit, $1200 for the next and $1600 for the third.
