Summary
BMW M3
There’s no point waxing too lyrical here, because the facts surrounding the M3 Touring are more than exciting enough.
It’s a (kind of) family friendly wagon with oodles of space and practicality. It’s also an unhinged performance weapon with a thumping 3.0-litre twin-turbo-petrol inline six-cylinder engine.
And it has been years — decades, even — in the making. So, has it been worth the wait? Let’s strap in and find out.

Mercedes-Benz E63
Feels like lately all the Mercedes-AMG buzz has been at the smaller end of the scale.
Most recently, the screaming GLA 45 S has arrived in Australia, pumping out more kilowatts and newton-metres than any compact SUV has a right to.
But here, we're doubling the cylinder count to eight, arranging them in a vee, and lighting the wick on AMG's powerhouse mid-size sedan, the recently upgraded E 63 S.
While the ferocious twin-turbo V8 and the rest of this beast's powertrain are unchanged, the car has been brought up to speed with some aero-focused styling tweaks, Merc's latest 'Widescreen' digital cockpit, as well as the MBUX multimedia system, and a tricky new multi-function sports steering wheel.

Verdict
BMW M38/10
Long live the mighty wagon. The BMW M3 Touring is treat to look at, and an even bigger treat to drive.
If you want one, act fast. We waited a long time for a wagon-shaped M3, and with electrification increasing in the automotive industry, this will likely be your last chance.
Mercedes-Benz E638.4/10
The E 63 S fills its niche in AMG's Australian line-up perfectly. More mature than the brand's four-cylinder hatches and SUVs, but not as overbearing as some of its bigger sedan, GT and SUV stablemates. And its ability to seamlessly switch between serene comfort and dynamic performance has nailed the objective for this 2021 update.
Design
BMW M3
It looks spectacular, this M3 Touring, and even more so given a) wagons are so rare, and b) proper low-riding performance wagons with massive alloys are even rarer.
That said, I expect it will be polarising – and possibly too shouty for some – but I've got to say, I like it.
I’ve seen it described elsewhere as a bit of a sleeper, but for mine, you’d need painted-on eyes to not see there’s plenty going on with the Touring, especially one finished in the same Frozen Black paint as our test car.
It is at once sleek and swept back, and bulging and aggressive, especially at the flared wheel arches and fat exhausts poking from its diffuser-filled rump.
Inside, it’s mostly business as BMW usual, though with more carbon-fibre elements — our vehicle was equipped with the M Carbon Experience pack — but snug-fitting seats aside, it’s a premium, if performance-focused, place to spend time.
Mercedes-Benz E638/10
The E 63 S has been massaged for 2021 starting with flatter headlights, AMG's now signature 'Panamericana' grille, and a high gloss black flap across the top of the curved 'Jet Wing' section defining the lower part of the nose.
At the same time, the vents on either end of it are larger and feature twin transverse louvers to guide cooling air to wherever it's needed.
It's all about what AMG calls 'optimised aerobalance' but the form is just as appealing as the function. The characteristic 'Power Domes' in the bonnet dial up the muscle, as do the fat wheel arches (+27mm each side), and 20-inch rims with distinctive aero inserts.
This car's optional exterior carbon package consists of a front splitter, side sills, a flash near the fender badges, the exterior mirror covers, the boot lid lip spoiler, as well as the lower apron around the redesigned diffuser and quad tailpipes.
New, intricately styled LED tail-lights are also flatter, but there's even more going on inside.
A new AMG sports steering wheel features three rounded twin-spokes with new switches on the bottom to control the car's dynamic set-up.
It also picks up a new take on the small touch-sensitive controllers used to adjust the instrumentation and manage other functions like phone calls, audio and the cruise control.
Not sure I'm in love with them at this stage. In fact, the words fiddly, imprecise, and frustrating come to mind.
Nappa leather covering the superb AMG sports seats, upper dash, and door beltlines remains standard, but the show-stopper is the 'Widescreen Cockpit' - twin 12.25-inch digital screens for the MBUX multimedia interface on the left and instruments on the right.
The instrument cluster can be set to 'Modern Classic', 'Sport' and 'Supersport' displays, with specific AMG read-outs such as engine data, gear speed indicator, warm-up status, car set-up, as well as a G-meter and 'RaceTimer.'
To borrow an official automotive design term, it looks schmick. Overall, with touches like open-pore black ash wood trim, and brushed metal highlights, the interior looks efficient but classy, with an obvious attention to detail in the layout and its execution.
Practicality
BMW M3
A performance-focused wagon is still a wagon, right? And that means there is oodles of space in the boot, though the seating choices in our test cars made the front seats less comfortable than they could, and should, be.
But first, the boot. The M3 Touring is a 4.8m-long wagon, which pays dividends when it comes to cargo. BMW says you'll find a minimum 500L of storage space, which grows to 1510L with the rear seat folded.
In the back, you’ll find seating for three, with the requisite ISOFIX attachment points, and with enough head and leg room to get comfortable.
But those carbon front seats are an option I wouldn’t be springing for. They arrive carved out of the rock-hard material, though with big holes throughout to reduce their overall weight, and they’re not only challenging to climb in and out of, but they’re awkward and hard to sit behind.
Stick with the regular seats and both rows will be happier.
Mercedes-Benz E638/10
At just under 5.0m end-to-end the E-Class sits in the upper range of the mid-size luxury spectrum. And almost 3.0m of that is accounted for by the distance between the axles, so there's plenty of space inside.
The driver and front passenger are provided with heaps of room to breathe, and there's a surprising amount of space for those in the back as well.
Sitting behind the driver's seat set for my 183cm (6'0”) position I had more than adequate head and legroom. But access to and from the back is a struggle for full-size adults.
The rear doors open out a long way, but the limiting factor is the size of the aperture, necessitating excessive contortion of the head and limbs to fold in and out of the car.
Connectivity runs to two (power-only) USB-C sockets in the front centre storage bin, as well as another USB-C (for power and multimedia) and 12-volt power outlet in the centre console.
Speaking of the front centre storage bin, it's a decent size and has a padded split lid so it can double as an armrest. There are two cupholders in the front console, a generous glove box, as well as long door compartments with recesses for large bottles provided.
There's a pair of USB-Cs along with another 12-volt socket in the back, sitting under the climate control panel with adjustable vents in the rear of the front centre console. Nice.
The fold down centre armrest incorporates a lidded (and lined) storage box as well as two pop-out cupholders. Again, there are bins in the doors with room for smaller bottles.
The boot offers 540 litres (VDA) of volume, and is able to swallow our three-piece hard suitcase set (124L, 95L, 36L) with room to spare, or the substantial CarsGuide pram, or the largest suitcase and pram combined! There are tie-down hooks to help secure loads, too.
Don't bother looking for a spare of any description, a repair/inflator kit is your only option. And the E 63 S is a no-tow zone.
Price and features
BMW M3
The BMW M3 Touring lists at $180,100, which isn’t chump change, and positions the wagon body shape a fair way above a regular M3 sedan.
That’s before on-road costs, of course. According to BMW’s website, putting an M3 Touring on the road in NSW will be more like $194,039 — before you start ticking option boxes.
The 'M Carbon Experience' adds $17,500, and reduces overall weight by close to 10kg through carbon bucket seats, and adds more visible carbon and even more possible headroom to fit a helmet
The 'M Carbon ceramic brakes' add another $16,500, and while there are plenty of free paint colours, you can pay up to $7000 for the 'Frozen White' paintwork.
Our test car was finished in 'Frozen Black', a bargain at $5K.
Elsewhere, there is plenty of equipment on a stacked standard features list.
That includes staggered 19- and 20-inch alloys, BMW’s digital 'Laserlight' headlights, and an automatic boot.
Inside, there’s a 'BMW Live Cockpit' with a 12.3-inch instrument display, a 14.9-inch central screen, a head-up display, wireless device charging, Apple CarPlay and Android Auto and a premium Harman Kardon surround sound stereo.
You also get three-zone climate, leather seats, an 'Active M Differential' and 'Adaptive M Suspension', and seat heating up front.
Oh, and there is lots — lots — of performance, but we’ll come back to that shortly.
Mercedes-Benz E638/10
So, first of all, let's get the price out of the way. At $253,900, before on-road costs, this car's competitive set is a bruising, all-German trio comprising the Audi RS 7 Sportback ($224,000), BMW M5 Competition ($244,900), and Porsche Panamera GTS ($309,500).
And no surprise, it's loaded with all the luxury features you'd expect in this part of the market. Here are the highlights.
On top of the standard performance tech and safety equipment fitted to the E 63 S (covered later in this review), you'll also find: Nappa leather trim (seats, upper dash, upper door cards, and steering wheel), MBUX multimedia (with touchscreen, touchpad, and 'Hey Mercedes' voice control), 20-inch alloys, three-zone climate-control, interior ambient lighting, auto LED headlights (with 'Active High Beam Assist Plus'), eight “energising comfort programs” (with 'Energising Coach'), an 'Active Multicontour' front seat package, the 'Air Balance' package (including ionisation), and keyless entry and start.
Also included are the the 'Widescreen' digital cockpit (twin 12.25-inch digital screens), 13-speaker Burmester audio with digital radio, Apple CarPlay and Android Auto, a panoramic sunroof, adaptive cruise control, a head-up display, augmented reality satellite navigation, 'Parktronic' self-parking, electric front seats, seat cooling and heating front (heated rear), heated front centre armrest, a power-adjustable steering column, auto rain-sensing wipers, a wireless device charger, illuminated door sills, as well Amazon Alexa, etc, etc, etc.
And our test car also featured a couple of tasty options. An exterior carbon package ($7500), and AMG's professional grade ceramic composite brakes ($15,900), for an as-tested price of $277,300.
Under the bonnet
BMW M3
The M3 Touring’s engine might well be one of the best in the business – a hard-charging 3.0-litre twin-turbo-petrol inline six-cylinder engine that produces a sizeable 375kW and 650Nm.
That power is sent to all four wheels via BMW’s 'M xDrive' with Active M Differential, producing a sprint to 100km/h of just 3.6 seconds.
Mercedes-Benz E639/10
The E 63 S is powered by the M178 version of the all-alloy 4.0-litre twin-turbo V8 engine used across numerous AMG models from the C-Class up.
Thanks in no small part to direct injection and a pair of twin-scroll turbos (located in the engine's 'hot vee' to optimise throttle response), this all-alloy unit produces 450kW (that's 612hp) from 5750-6500rpm, and 850Nm from 2500-4500rpm.
And as per standard AMG practice for its Vee engines, this car's powerplant was built from scratch by a single engineer in Affalterbach. Thank you Robin Jäger.
AMG calls the nine-speed transmission used in the E 63 S an MCT, which stands for Multi-Clutch Technology. But it's not a dual-clutch, rather a normal auto transmission using a wet clutch as opposed to a conventional torque converter, to connect it to the engine on take-off.
Drive goes to all four wheels via Merc's '4Matic+' AWD system, built around an electromechanically controlled clutch connecting the permanently driven rear axle (with locking diff) variably to the front axle.
Efficiency
BMW M3
Officially, you should see a claimed 10.4L/100km on the combined cycle, but as is often the case in cars with engines that tempt you to be aggressive with the accelerator, the reality can be a little different.
We saw more like 16.4L/100km, but in the big bruiser’s defence, we spent a lot of time in city and suburbs, and a lot more time standing on the accelerator.
The M3 Touring is fitted with a 59-litre tank, and will only accept 98RON premium fuel.
Range is close to 570km using the official consumption figure and around 360km using our real-world number.
Mercedes-Benz E637/10
Claimed fuel economy for the combined (ADR 81/02 - urban, extra-urban) cycle is 12.3L/100km, the E 63 S emitting 280g/km of CO2 in the process.
That's a pretty hefty number, but in line with this car's proportions and performance potential.
And Merc-AMG has gone to great lengths to minimise fuel use. As well as the standard 'Eco' stop-start function, in the 'Comfort' drive program cylinder deactivation becomes active, the system able to drop four cylinders anywhere between 1000 to 3250rpm.
There's no physical hint of half the cylinders leaving the party. The only clue is a blue icon on the dash indicating a temporary shift to V4 operation.
Despite all that effort, however, we saw a dash-indicated 17.9L/100km over a mix of urban trundling, highway cruising, and some spirited dynamic assessment.
Recommended fuel is 98 RON premium unleaded (although it'll run on 95 at a pinch), and you'll need 80 litres of it to fill the tank. That capacity translates to a range of 650km according to the factory claim, and 447km using our real world result.
Driving
BMW M3
In a word? Delightful.
Don’t get me wrong, it’s not the easiest car in the world to daily drive. The carbon-fibre seats fitted to ours, for example, made getting in and out a slightly embarrassing challenge, and there’s a surging eagerness to the delivery of power that makes you look a little like you're showing off.
But the adaptive suspension serves up a far more comfortable ride than you might be expecting (more comfortable, in fact, than lesser, cheaper M models), making tootling around town easier and less chiropractic than I was expecting.
But it’s away from the city, with its traffic and red lights, that owning the M3 Touring becomes a delight, from its potent and punchy powertrain to the thrum of its exhaust, and the EV-like immediacy of its power delivery.
This is a driver’s wagon, there’s no doubt about it, with proper seatback-pushing acceleration, direct and confident steering and enough body stiffening and bracing that you really would have no idea you’re driving a wagon when cornering.
Engage its sportiest settings, and disengage its electronic nanny systems, and you can even set to work judging your drifting skills, courtesy of the (as yet untested, honestly) 'M Drift Analyser'.
A family car like few others, then. That you can also take it to Bunnings and throw some sleepers in the back is just a very welcome bonus.
Mercedes-Benz E639/10
AMG's major goal with this upgrade of the E 63 S was to maintain its dynamic response and ferocious performance, but dial in the extra comfort customers had said they wanted.
So, the 4Matic+ AWD system has been fine-tuned for more smoothness as has the Comfort option in the dynamic set-up. But we'll investigate that shortly.
First, that 4.0-litre turbo V8 in the nose is claimed to slingshot this roughly 2.0-tonne sedan from 0-100km/h in just 3.4 seconds, and it feels every bit that fast.
With 850Nm available from 2500-4500rpm and nine gear ratios to help keep you operating in that Goldilocks band, mid-range thrust is monumental. And thanks to the bi-modal sports exhaust it sounds beautifully brutal.
The nine-speed auto's wet clutch, as opposed to a conventional torque converter, is designed to save weight and optimise response. And while some will tell you an auto with one input shaft is never going to be as fast as a dual-clutch with two, shifts are rapid and direct. The wheel-mounted shift paddles are larger and set lower, as well.
The AMG 'Ride Control+' suspension with multi-chamber air suspension and adaptive damping is amazingly good. The underlying set-up is by multi-links front and rear, and despite riding on big 20-inch rims wrapped with low-profile, high-performance Pirelli P Zero rubber (265/35 fr - 295/30 rr) the Comfort setting is incredibly... comfortable.
Slip into 'Sport' or 'Sport+' and the car immediately feels tauter but far less compliant and forgiving. An impression reinforced by the engine, transmission, and steering shifting to a more buttoned-down mode at the same time.
The standard dynamic engine mounts play a big part here. Able to make a soft connection for maximum comfort, but switch to a rigid link when required.
But no matter which mode you're in, the car is well damped and feels beautifully balanced in quick cornering. And the E 63 S's electro-mechanically-assisted variable-rate steering is progressive, feelsome, and accurate.
The 4Matic+ AWD system is built around an electromechanically controlled clutch connecting the permanently driven rear axle (with locking diff) variably to the front axle.
Torque distribution happens imperceptibly, the big V8 putting its power down emphatically, with various electronic systems tieing up the loose ends as you aim up for the next corner.
There's even a 100 per cent RWD Drift mode available in the Race setting, but without a race circuit at our disposal this time around that'll have to wait for another time.
The optional ceramic brakes feature huge rotors and six-piston front calipers, and stopping power is immense. And the good news is they operate quickly but progressively at normal pottering around town speeds. No warming up required to get them in an optimal temperature zone (as can be the case with other ceramic set-ups).
Safety
BMW M3
Neither the M3 or M3 Touring have been independently crash tested to date, but it’s worth pointing out the 3 Series and 4 Series received maximum five-star scores from Euro NCAP.
Standard safety kit includes AEB with pedestrian detection, active lane keeping assist, blind spot monitoring, adaptive cruise control and rear cross-traffic alert.
You’ll also find six airbags on board.
Mercedes-Benz E6310/10
The three-pointed star's white-coated boffins have gone to town on the E 63 S, and the car is as good as it currently gets in terms of active and passive safety technology.
You could argue this car's dynamic ability is its strongest contributor to crash-avoidance. But a broad suite of features, specifically designed to keep you out of trouble includes, forward and reverse AEB (with pedestrian, cyclist, and cross-traffic detection), traffic sign recognition, 'Attention Assist', 'Active Blind Spot Assist', 'Active Distance Assist', 'Active High Beam Assist Plus', 'Active Lane Change Assist', 'Active Lane Keeping Assist', and 'Evasive Steering Assist.' That's a lot of assists.
There's also a tyre pressure monitoring and pressure loss warning system, as well as a brake priming function (monitors release speed on the accelerator pedal, moving pads factionally closer to the discs when required), and brake drying (when the windscreen wipers are active the system periodically applies just enough brake pressure to wipe water off the brake rotors to optimise wet weather efficiency).
But if an impact is unavoidable the 'Pre-Safe Plus' system is able to recognise an imminent rear-end collision and fire up the rear hazard lights (at high frequency) to warn following traffic. It will also firmly apply the brakes once the vehicle is stationary to minimise the risk of whiplash injuries if the car's then hit from behind.
If the potential crash is coming from the side, 'Pre-Safe Impulse' inflates air chambers in the side bolsters of the front seat backrest (within a fraction of a second) moving the occupant to the side towards the centre of the car, away from the impact area. Amazing.
As well as that, there's an active bonnet to minimise pedestrian injuries, an auto emergency call function, 'Crash Response Emergency Lighting', even a first aid kit and hi-vis vests for all occupants.
For the record, the current E-Class received a maximum five-star ANCAP assessment in 2016.
