Audi RS4 VS Mercedes-Benz E-Class
- Immense traction
- Easy to drive fast
- Practical, too
- Steering not perfect
- Missing one or two things
- S4 makes better financial sense
- Numb steering
- Rear headroom in coupe/cabrio
- So-so warranty
Think about the word ‘functional'. You might notice that there are three letters at the start of the word that people don't often associate with station wagons. That's not the case for the 2018 Audi RS 4.
This isn't your everyday station wagon. It's a hyperbole-generating monster - a family-friendly estate with a licence to punish. Audi goes as far as to suggest that it offers "supercar performance and everyday practicality".
And why wouldn't it? With a bolshie engine, all-wheel drive and more grunt than a pair of conjoined twin hot-hatches, it's a model that has little to prove... especially to those people who appreciate what those precious first three letters can do to improve a drab drive in city traffic.
But there's something that can't be understated about this new-generation RS 4: it isn't like the model that came before it. There's no V8 engine under that shapely bonnet, because of the the new RS 4 isn't like the old one. The V8 is gone... and yes, when I first read that Audi had done the unthinkable and pulled the bahnstorming eight-cylinder screamer in favour of a downsized twin-turbo six I was shocked and horrified.
Without its star attraction, could it still be fun? I don't want to spoil the story, so be sure to read on to find out...

To say Mercedes-AMG is popular in Australia is like saying the young people are fond of Drake, or that football fans seem to appreciate Ronaldo’s skills.
Per head of population we buy more of the three-pointed star’s go-fast specials than any other country on the globe. Typically, between 15 and 20 per cent of all Mercs sold here are of the AMG variety.
The ‘43’ suffix appeared on C and E Class variants, meaning a 3.0-litre, twin-turbo V6 had been slotted under the bonnet, providing enough grunt for day-to-day enjoyment without the hardcore edge of a big-banger V8.
But the boffins at AMG’s Affalterbach HQ can’t seem to help themselves because the E 43 has been replaced by, you guessed it, the gruntier E 53.
Powered by a 3.0-litre, in-line six-cylinder turbo engine, the 53-series delivers close to 15 per cent more power and a huge dollop of extra torque courtesy of its tricky ‘EQ Boost’ starter/alternator system.
So, has the civility and relative efficiency of Merc-AMG’s only slightly psycho E Class models been maintained, or has another beast been released?

There is no doubting that the all-new Audi RS 4 is a pragmatic option, probably more so now than ever before. It does the dual-personality thing better than the model that came before it, and perhaps better than anything else at this price point, too.
If you want a practical family wagon that just also happens to be punishingly fast, and you have the budget to consider something like the new Audi RS 4, it should be on your shopping list. And probably towards the top, too.
Are you a fan of fast station wagons? Let us know in the comments section below.
The Mercedes-AMG E53 is a supremely refined and satisfying performance/luxury package. For those who want the practicality and style of a high-spec E-Class, with an extra performance boost (but not the full-fat V8 drama) it’s got to be an appealing option. Plus, the high-tech hybrid drivetrain is brilliantly executed and seamless in operation.
Does the E 53 AMG do enough to warrant the hallowed Affalterbach seal of approval? Tell us what you think in the comments section below.
If you like wagons, you'll totally get it. If you're a hater, or even ambivalent, then you'll probably still get it.
Admittedly it could look even more aggressive, but it has to balance practicality with pouncing killy animal aggression. Even so, I think there's a lot to like here, from the squared-off front and rear quarter panels, the broad (even broader than the regular A4 range, in fact) 'single-frame' grille, and the bejewelled looking LED headlights.
It looks even better from behind, with the broad rear haunches really hunkering it down, and the wide tail-lights and sneaky little fake vents on the side adding extra back-end bulk. Note: the rear light-edge vents may be fake, but the front ones actually work to channel air to cool the brakes.
There are 20-inch wheels in a few different designs, but my personal choice would be the milled aluminium single-piece ones you see on the blue car in these images. They're gorgeous, even if they cost more. And I couldn't not have the signature Nogaro Blue Pearl, which was the same colour as the RS 2 wagon that started the hot wagon thing for Audi... again, at a high price.
Thankfully, I wouldn't need to spend an extra cent inside, because the interior is lush. There are all the typically Audi finishes - it's a high-end and luxurious environment, but with lashings of sporty elements that help it feel almost like a leather tracksuit. Take a look at the pictures of the interior to make up your own mind.
Compared with, say, a regular A4 Avant, the RS 4 Avant is bigger in every way except height. It measures 4781mm long (up 56mm), 1886mm wide (up 44mm) and 1404mm tall (down 30mm). It's quite heavy, too, weighing in at 1800kg, which is about 150kg more than the entry-level wagon.
As good as it looks, I just can't help but think maybe it could have been even more aggressive. The last model certainly had muscle and more macho with its even more angular guards. But maybe the world has moved on a bit, and I'm just not ready for it.
Keen car-spotters will pick the E 53 courtesy of its ‘twin-blade’ radiator grille (in silver chrome) with black mesh insert in place of the standard E-Class ‘diamond’ version, and a distinctive ‘A-wing’ front apron design.
AMG-specific side sill panels link the front fascia to a rear treatment including a high-set diffuser panel and quad exhaust tailpipes finished in high-gloss (black) chrome.
The interior doesn’t vary dramatically from other high-end E-Class variants, the biggest differences being grippier, leather-trimmed sports seats, dark ash wood trim on the dash, console and doors, plus an ‘AMG Performance’ steering wheel trimmed in nappa leather.
A twin (12.3-inch) screen ‘Widescreen Cockpit’ media and instrument array includes the ability to scroll through an AMG-specific digital display, scrollable through ‘Classic’, ‘Sporty’ and ‘Progressive’ configurations.
Via the AMG menu it’s also possible to call up read-outs including engine and transmission oil temp, acceleration (longitudinal and lateral), engine outputs, turbo boost pressure, tyre temps and pressures, as well the current vehicle set-up.
Don't get me wrong, it's still a very, very pleasant place to be. Typically Teutonic, typecast technical Audi, but with some sporty flourishes. The hard-backed sport bucket seats up front offer a great amount of adjustment (though the driver's seat base is a little too high), and depending on what interior trim you opt for, you may see aluminium or carbon finishes throughout.
The quilted leather is lovely, and the materials are all superb - so is the fit and finish. One of the cars I drove had an optional pack with Alcantara trim, with that material covering the shifter and steering wheel - the latter of which I love, because it's smooth yet grippy. I'm not so sold on manual steering adjustment for a car at this price point, however.
With the Audi Virtual Cockpit digital screen spreading 12.3-inches in front of the driver, there's no shortage of info to choose from. It's been around a few years now, but I still love the look of Google Maps in front of me.
There's also Audi's MMI touch system, a rotary dial with a touchpad on top that is pretty simple to use, and it links up to a high-resolution 8.3-inch screen on the dash top. All the connectivity stuff you'd expect is included - Apple CarPlay, Android Auto, Bluetooth phone and audio, DAB+ digital radio, and an inbuilt hard-drive for your own music storage. You won't be left wanting for entertainment.
There are reasonably good sized cup holders up front, a covered centre console, some loose-item storage areas and adequate bottle holders in all four doors. The back seat has mesh map pockets (set on hard plastic seatbacks - good for limited damage to fabric if you have children who like to kick the seat) and a flip-down armrest with cupholders.
Space in the rear is easily good enough for a six-foot (183cm) tall adult like myself to slot behind someone of the same size, with ample kneeroom, good toe room and enough headroom to ensure no hairs were out of place. The width is surprisingly decent, too.
There are dual ISOFIX child-seat anchor points, and three top-tether attachments as well. And parents (and children alike) will appreciate the rear air vents, and three-zone climate control system that allows a seperate temperature in the back.
The boot is a good size, with 505 litres of capacity up to the multifunctional luggage cover (which includes an integrated mesh cargo barrier and operates electronically in conjunction with the boot lid). It also has a reversible floor section - carpet one side, plastic on the other - perfect for tying down wet clothes (using the included mesh elasticated web net) or even performing potentially messy nappy changes. The boot expands to 1510L with the seats down.
Despite availability in sedan, coupe and cabriolet form, the E 53 launch drive program focused exclusively on the coupe and cabrio.
Like all E-Class models the E53 offers plenty of space up front, as well as a generous, lidded console box incorporating multiple USB ports.
A second flip-top section in front of the media controller houses a pair of cupholders, oddments space and a 12-volt power outlet, plus there’s a medium-size glove box, and the doors feature long bins including big bottle holders.
Rear room in the sedan is typically E-Class generous, with three adults across the back seat a genuine option on shorter journeys.
Adjustable air vents are welcome, and a fold-down armrest houses two cupholders and a lidded bin, with another two USB ports provided. Door pockets incorporate bottle holders and there are map pockets on the front seatbacks.
The sedan’s boot capacity is 540 litres, more than enough to swallow a pram and accompanying baby ‘stuff’, or our three-piece hard suitcase set (35, 68 and 105 litres). And the 40/20/40 split-folding seat back liberates yet more space.
Backseaters (two only) in the coupe and cabrio are well catered for. Legroom is surprisingly substantial, although with the roof up, at 183cm, headroom for me was just adequate. With the cabrio’s roof down however, that improved considerably. Worth noting that sensors in the front seats’ adjustment system stop them from hitting a rear passenger’s knees. Nice.
In terms of storage and convenience, there’s a pair of cupholders between the seats, adjustable air vents, map pockets, and some oddments space near the outside armrests.
Boot capacity in the coupe is 425L and 385L in the cabrio, with the rear seat splitting and folding to offer through-loading space. An electrically controlled, retractable separator in the soft-top’s boot defines the space filled by the roof when folded (which still leaves 310L).
Tyres are run-flat on all variants, so don’t bother looking for a spare of any description.
Price and features
The new twin-turbo V6 model is priced at $152,900 plus on-road costs, which represents a slight hike over its V8-powered predecessor, but Audi claims to have added $22,000 of extra equipment.
Standard inclusions offered in the RS4 consist of 20-inch alloy wheels, red RS brake calipers, an adjustable sports exhaust system, Audi's sport differential, adaptive sports suspension, LED headlights with LED daytime running lights, adaptive rear LED indicators and tinted rear windows with acoustic front glass.
Standard interior kit includes Audi's 'Virtual Cockpit' 12.3-inch driver info screen with configurable RS display mode, an 8.3-inch tablet media screen with sat nav, Bluetooth phone and audio streaming, Apple CarPlay and Android Auto phone mirroring, DAB+ digital radio, and a stonking 19-speaker Bang & Olufsen stereo system.
The front sports seats with Nappa leather trim and honeycomb quilting (which apparently mirrors the design of the grille mesh) also feature bolster adjustment, massage function, memory settings for the driver's seat and electric adjustment and heating for both sides. There is an ambient-lighting system with 30 different colour options, too.
A panoramic sunroof is fitted as standard, but for hot areas of the country it can be deleted if the buyer so chooses. Smart key entry and push-button start is standard, and there's an auto tailgate with gesture control.
Even though that list is long, there are still option boxes you can choose to tick. Things like the carbon and black styling pack ($11,900), the 'Technik Pack' (with head-up display, Matrix LED headlights, wireless phone charging - $3900) and other style-focused extras like the 20-inch milled aluminium wheels ($1600). There are several colour options to choose, including the Misano Red pearl finish ($1846), or the brilliant 'Nogaro Blue Pearl' ($5450)... but not all the colours cost money, with a selection available at no cost.
See below for the extensive safety kit list - because it's hugely lengthy!
As for where the competitors sit, the Mercedes-AMG C63 S wagon lists a little higher, at $159,711 plus on-roads. There's no BMW M3 wagon, but the sedan version is $141,610 plus costs... and it's the only one with manual or auto to choose from. There's no Lexus, Infiniti or Volvo equivalent model. But I guess you could consider the S4 a good alternative at $50,000 less, and it's available as a sedan or a wagon...
Pricing for the Mercedes-AMG E 53 ranges from $167,129 (plus on-road costs) for the sedan, through $172,729 for the coupe, and $181,329 for the cabriolet.
Then the cabrio is something of an outlier, with the BMW M4 Competition ($165,615) again a smaller but faster and cheaper option. In the hunt for other performance-focused 2+2 convertibles, you’re into the entry-point of Porsche’s 911 line-up with the Carrera Cabriolet ($248,350) representing a close to $70k premium.
All variants are suitably well equipped. On top of the standard performance and safety tech detailed in later sections, the E 53 is fitted with dual-zone climate control, 13-speaker Burmester audio (including digital radio and Apple CarPlay compatibility), keyless entry and start, nappa leather trim, sports seats, ‘AMG Performance’ (flat bottom) sports steering wheel (also trimmed in nappa leather), adaptive LED headlights (plus active high beam), and 20-inch alloy wheels.
Also included are the Widescreen Cockpit display (twin 12.3-inch screens covering multimedia and instruments as well as ‘Linguatronic’ voice control), sat nav, ambient interior lighting (64 colour options), active cruise, a configurable head-up display, electric front seats (heated with memory), wireless phone charging, wood grain interior trim, electric steering column adjust, rain-sensing wipers, and a panoramic sunroof.
All that stacks up well for a contender in this part of the market. You pay the big bucks, you get all the fruit.
Engine & trans
This isn't the first time the Audi RS 4 has had a twin-turbo V6 engine under its bonnet. Back in 2000, the very first RS 4 launched with a 2.7-litre biturbo engine.
This all-new model has a 2.9-litre twin-turbo unit, which shares much with the Audi S4 and S5 models (they run a 3.0-litre turbo - the engine in the RS 4 is a smaller capacity and has a shorter stroke, but adds a turbo over the lesser S models).
It's no V8, however. The most recent model before this one had a 4.2-litre naturally aspirated unit with 331kW of power and 430Nm of torque.
This new version carries over the same power output - 331kW - but it hits between 5700-6700rpm, not at 8250rpm like the old V8. And torque has seen a substantial kick up the behind, now rated at 600Nm.
Not only has torque increased by about 45 per cent, it's also across a broader rev range - now it spans 1900-5000rpm, where it was not only lower but shorter-lived and less usable in the V8 (4000-6000rpm).
And the all important 0-100km/h time? It's now at 4.1 seconds, where it used to be 4.7sec. The top speed remains identical - 250km/h.
What about the sound, though? Read the driving section below... or better yet, watch the video!
Already used in other AMG models, including the entry-level version of the just-released flagship GT 4-Door, the E 53’s (M256) in-line six is a 3.0-litre all-alloy unit featuring direct-injection and a single turbo, supplemented by an electric compressor (turbo if you prefer) which builds up charge pressure prior to the main turbo coming on song. Turbo lag, be gone!
The EQ Boost starter-alternator is housed in an electric motor fitted between the engine and transmission, driving a 48-volt electrical system to support the additional compressor as well as the car’s traditional 12-volt functions (lights, cockpit, multimedia and other control units) through a DC/DC converter.
Maximum torque (520Nm) is available from just 1800rpm all the way to 5800rpm, with peak power (320kW) taking over at 6100rpm. But the EQ Boost’s hybrid party trick is the ability to drop in a brief full-throttle burst of 16kW/250Nm. Whoosh.
Drive goes to all four wheels via a nine-speed dual-clutch auto transmission and an AMG Performance turned version of Merc’s ‘4Matic’ all-wheel drive system, using an electro-mechanical clutch to distribute torque between the permanently driven rear axle and variably driven front axle.
Fuel consumption for the 2018 Audi RS 4 is rated at 8.9 litres per 100 kilometres, which is fairly good for a vehicle with this much propulsion potential. CO2 emissions are rated at 202g/km.
Both of those are big improvements over the V8 that preceded it - the claimed consumption was 10.7L/100km and emissions were 249g/km.
But it's worth noting that Mercedes-AMG has the C63 wagon with a 4.0-litre twin-turbo V8 that has more power (375kW) and torque (700Nm) yet uses less fuel (8.7L/100km).
Claimed fuel economy for the combined (ADR 81/02 - urban, extra-urban) cycle is line-ball for sedan (8.7L/100km), coupe (8.8L/100km), and cabriolet (9.0L/100km) variants, emitting 199, 200, and 204g/km of CO2 respectively in the process.
Start-stop is standard, minimum fuel requirement is 95RON premium unleaded, and you’ll need 66 litres of it to fill the tank.
It only took three corners for me to feel 100 per cent comfortable with the controls of the Audi RS 4. Some cars may take a few minutes before you become accustomed to how the throttle, brakes and steering want to be used, but it was mere seconds in this case.
That's because of the outright predictability of the RS 4 - it's hard to set a foot wrong, with excellent throttle response, strong but progressive braking, and better steering than I've experience in any Audi outside of the R8. It's not perfect - there's still a little bit of deadness or stickiness on centre - but I like the way it helps you pivot the car and apply lock at pace, thanks to nice weighting and resistance. The steering is light when you want it, and hefty when you need it.
The adaptive dampers and 20-inch wheels can't totally divorce the road surface from the bodies of the occupants in the cabin, and over patchy surfaces the ride can be a little pitchy, even in the Comfort setting.
But those dampers help stiffen the chassis up in Sport mode, negating body roll brilliantly. That, combined with the traction of the excellent quattro all-wheel drive system with a self-locking centre differential, and the grip of the Continental tyres makes for a really enjoyable way to cut through a series of corners.
Of course there are electronic helpers underneath, including a torque-vectoring-by-braking system and torque-splitting rear differential that pushes load to where it's needed most - but unless you had a screen in front of you telling when they were being used you wouldn't know. It all just feels really natural in the way it handles itself.
Now, that engine.
No, it isn't a V8, but what it is is a powerhouse weapon. It's still rev-happy, and the transmission allows it to be that way: in Dynamic mode with the shifter in S (not D) there is a brilliant willingness to the way it hangs on to gears - through a series of sweeping corners, getting on and off the throttle and brake pedal respectively, it had incredible intuition - third gear was the most usable, and gave the most, too.
The engine's sound isn't as visceral as the V8 of its predecessor, but it isn't what I'd call dull. There's a nice bit of chortle on the overrun, and it sounds pretty menacing when you punch the go pedal.
In normal driving, too, it's well suited to regular duties. It just so happens that its great at going fast, which is what you want from an RS model.
It only takes a few kilometres behind the wheel of the Mercedes-AMG E 53 to recognise that it fulfils its job description pretty well.
With claimed 0-100km/h acceleration sitting in the mid-4.0sec zone (coupe 4.4sec, sedan/cabrio 4.5sec) it’s fast, but not brutal. It growls without rising to the full-blown roar that’s become the aural signature of the current 63-series AMG V8s.
But don’t take that to mean meek and mild. It’s properly rapid and the sports exhaust, particularly with the drivetrain mapped to the ‘Dynamic Select’ system’s ‘Sport+’ mode leaves you (and everyone in a 200-metre radius) in no doubt that you’re driving something special.
Dynamic Select allows individual calibration of the engine, transmission, suspension and steering. Around town with everything dialled in to ‘Comfort’ the E 53 is as refined and compliant as any other high-spec E-Class.
Despite the standard 20-inch rims shod with low-profile run-flat rubber (245/35 front, 275/30 rear) the ‘AMG Ride Control’ adaptive damping combines with the overall air suspension system to provide excellent ride comfort.
Find a twisting B-road and push into ‘Sport’ or Sport+’ mode and the car’s character changes distinctly. All 520Nm of maximum torque is available from just 1800rpm right up to 5800rpm. And while that’s plenty, pin the throttle and an additional 250Nm (and 16kW), courtesy of the EQ Boost hybrid system joins the party.
Press on and as peak power (320kW) takes over at 6100rpm you’ll notice the horizon is approaching rapidly. The additional electric compressor means power delivery is beautifully linear, and the hybrid boost is undetectable.
The nine-speed dual-clutch auto is as smooth at parking speeds as it is at maximum attack. Manual changes (up and down) are rapid and positive, accompanied by entertaining blips and bangs from the exhaust in the more aggressive drive modes.
The coupe is the lightweight of the trio, weighing in at 1895kg, with the sedan and cabrio sending the needle roughly 100kg further to the right. But despite that not insubstantial kerb weight, and the all-wheel drive set-up, all feel light and nimble for their size.
While the variable steering adjusts seamlessly as lateral forces increase, no matter which mode is selected, road feel is modest at best. But the AWD system shuffles drive to the right wheel without fuss and power down out of quick corners is satisfyingly solid.
With all this performance, on-tap braking is critical, and the standard set-up is perforated and internally ventilated discs all around (370mm front, 360mm rear) clamped by four piston calipers at the front and single piston floating calipers at the rear. After an ‘enthusiastic’ session on the launch drive they remained progressive and strong.
The multi-adjustable sports front seats are comfy when they need to be, and with the side bolsters adjusted inwards, secure and grippy as G-force builds. Top-notch ergonomics complement this satisfying and well resolved dynamic package.
There is no model-specific Audi RS 4 Avant crash-test rating, but the Audi A4 (four-cylinder) range managed the maximum five-star EuroNCAP / ANCAP test score in 2015.
Rest assured, though, the RS 4 has a lot of standard equipment.
The standard safety equipment list includes Audi's pre-sense front system with auto emergency braking (AEB) with pedestrian detection (which works up to 85km/h), plus a 360-degree camera with reversing camera and front and rear parking sensors. Plus the traffic-jam assist system, which debuted in 2015 on the Q7 and uses two radars to read the road ahead - even scanning in front of the car directly in front of you.
There's active lane-keeping assist, lane-departure warning, blind-spot monitoring, adaptive cruise control, turn assist (which will stop you from driving through an intersection if the car doesn't think you'll make it), auto high-beam lights, rear cross-traffic alert (with audible, visual and physical notification - it can jolt the brakes if you aren't paying attention), multi-collision braking (which will stop the car if you have an accident to prevent further mishap).
There's also Audi's clever "exit warning system" that will flash the ambient lights if an occupant is about to open their door into the path of oncoming cars or cyclists.
The RS 4 has eight airbags (dual front, front side, rear side and full-length curtains).
You’d expect any current passenger model wearing the three-pointed star to be on the leading edge in terms of active and passive safety, and the E Class range scored a maximum five ANCAP stars when it was assessed in late 2016.
The E 53’s crash avoidance tech includes ABS, EBD, brake assist, AEB, ESC, traction control, blind spot monitoring, lane keep assist, fatigue detection, a surround camera system, tyre pressure monitoring, and traffic sign recognition.
And if a crash is unavoidable all models feature dual front and dual front side airbags, a knee airbag for the driver, plus full-length curtain airbags… even a first-aid kit.
The sedan features three top tether points and two ISOFIX child restraint anchor positions across the back seat, with a two-and-two count in the coupe and cabrio.
Audi covers all of its models with a three-year/unlimited kilometre warranty plan, which, by market standards is starting to look a little low, but in the premium part of the market, not many brands do much better.
As for servicing costs, it's a bit of a guessing game. The entire RS model range, as well as the R8 supercar, isn't covered by the same Audi Genuine Care pre-purchase setup you can get on a regular (non RS) model. That plan covers three years/45,000km of maintenance, and in the case of the A4/S4, the cost is $1620. Expect more than that for the RS 4.
Mercedes-Benz offers a three-year/unlimited km warranty, with 24-hour roadside assist included for the duration. Not exactly leading edge when you think about Kia at seven years/unlimited km and Tesla’s eight-year/160,000km cover.
Scheduled maintenance for the E 53 is set at 12 months/25,000km, and service plans are offered at silver and platinum levels for up to five years/100,000km.
