Summary
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.

BMW 3 Series
Back in the day, the 3 Series sedan was often the entry to the brand for first time BMW owners, and for good reason. They offered practical interior space without compromising on engine performance.
And they simply looked good, no boring nanny design elements. Then the 1 Series came along and price points bumped up, so how does the ‘entry’ BMW 320i M Sport live up to its long-standing reputation?
With an updated dashboard that brings the interior and tech up to market and a sharper exterior design, it more than holds its own at the table of luxury sedans, despite hard competition from the likes of the Audi A4, Mercedes-Benz C200 and Jaguar XE.

However, if the Merc is a placid and well-behaved mare… the BMW is the barely-broken-in bronco and it takes a certain kind of ‘rider’ to enjoy what the 320i has to offer.
I’ve been discovering just that this week with my family of three. What did we find out? Read below!

Verdict
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.
BMW 3 Series8/10
I thoroughly enjoyed my time in the BMW 320i M Sport. It’s fun to drive and I felt connected to what the car was doing on the road. The harder ride may not appeal to some but I didn’t mind it. The cosy back seat and boot mean it will probably suit a smaller family best and one which doesn’t have to worry about carrying a lot of gear around regularly, but it suited my needs just fine.
I reckon this is a car for those drivers who don’t want to compromise on performance but still have a kid or two. If you’re after the cushioned comfort of a Merc, this won’t appeal but I didn't want to give this one back and happily give it a firm 8/10.
My son liked the sports car looks and enjoyed the amenities in his row. He gives it a 10/10.
Design
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.
BMW 3 Series
Sharper than its predecessor, the new 320i has LED everything with the rear lights being longer and curving around to the sides of the car.
The classic 'kidney' grille is darkened and more pronounced, with the black panelling extending to the rear to create an unapologetically sporty presence. A presence that’s accentuated by the twin exhausts.
The batcave interior with its black headliner, black seats… black everything, looks smart and stylish.
You do have a fair bit of harder touchpoints throughout but the customisable ambient lighting helps to soften the overall effect.
With its 2068mm width, 4709mm length and 1435mm height, the sedan makes its presence known without feeling cumbersome to manoeuvre. Urban dwellers need not fear their local car park!
Practicality
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.
BMW 3 Series
For such a sleek looking sedan, it’s generous up front with plenty of head and legroom.
You can adjust the seat to sit quite low and both front seats have extendable under-thigh supports, which should excite taller drivers.
My 189cm (6’2”) brother has the 328i and is very comfortable but taller front passengers will encroach on back seat passenger comfort.
The front seats are quite firm on the backside, they also lack adjustable lumbar support, so expect to stretch the kinks out on a longer trip.
The amenities and tech feel well thought out and easy enough to use. The 12.3-inch touchscreen multimedia system looks great and has the best-looking graphics I’ve sampled.
The BMW system is intuitive to use once you get used to it. If you’re not interested in using the touchscreen, you can also utilise the rotary-wheel for menu selections.
There’s also Bluetooth connectivity, wireless Apple CarPlay and Android Auto plus built-in satellite navigation.
The 12.3-inch digital instrument panel is customisable and the information displayed simply but you won’t really look at it because of the head-up display.
Front occupants enjoy a wireless charging pad for their smart phone, a USB-A and USB-C port plus a 12-volt socket. Rear passengers get a couple of USB-C ports, too.
The storage is good for this size sedan but overall passenger room takes priority, but the glove box and middle console will suffice for everyday use.
While it may not excite others, I love the big bottle holders in the doors. They’re large enough for my big 1.5L bottle and angled for easy access. These are found in the rear doors as well.
Back seat passengers enjoy climate control, directional air vents, two cupholders, netted map pockets and reading lights.
My six-year old was happy with the amenities and lower ground clearance because he felt comfortable and had his independence.
The boot offers a good capacity of 480L and the aperture isn’t too narrow, so you can comfortably access items if they roll to the back.
I had plenty of room for my little family’s needs but if you’re a larger family, you may need to get strategic with gear storage.
Being a base model, you do miss out on a powered tailgate, which is a shame but not too much of an issue given this is a sedan and the lid isn’t heavy.
There’s also no spare tyre or even a puncture repair kit but you have run-flats, so you should be able to limp to a service centre if need be.
Price and features
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.
BMW 3 Series
There are seven variants for the BMW 3 Series sedan and our model is the base model for the petrol variants.
There is a plug-in hybrid version, the 330e, if you’re after a more fuel-efficient option but it will up the price by about $20K.
As it stands the 320i M Sport is $78,900, before on-road costs. Our model has been finished in 'M Brooklyn Grey', which adds $1539 to the price.
That puts it at a similar price point as its rivals. You get a well-specified package with the M Sport but it doesn’t have the same sense of cushioned comfort as the Merc does, but more on that later.
Still, the sporty and streamlined interior is headlined by BMW’s dual 12.3-inch screens that sit propped on the dash like a futuristic cockpit.
The mix of synthetic leather and cloth seats are electric and have adjustable side bolsters for when you want to go hard in a turn.
The interior also boasts a sunroof and wireless Apple CarPlay and wired Android Auto. There are some other highlights like the 18-inch alloy wheels, leather steering wheel and the crystal-clear head-up display, to name a few.
Under the bonnet
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.
BMW 3 Series
The 320i M Sport has the ‘baby’ engine in the 3 Series line-up but the 2.0-litre, four-cylinder turbo-petrol powertrain still delivers on power with a maximum output of 135kW/300Nm.
This is a rear-wheel drive and has an eight-speed auto-transmission which delivers very smooth gear changes.
Despite having the smaller engine, it can still go from 0-100km/h in just 7.4 seconds.
Efficiency
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.
BMW 3 Series
In a world with rising fuel prices, the efficiency of this decently powered sedan should excite you.
The official combined fuel cycle is 6.5L/100km. Real world testing saw my figure at 7.4L/100km after a mix of open-road and urban driving this week.
I thought that was great for how hard I drove it and for the power, you won’t be wincing when you put your foot down. I would expect it to be higher in an urban setting.
The 320i has a 59L fuel tank and based on the official combined cycle figure, you should get just over 900km of driving range, which is great, especially if you do 'roadies' like me!
Driving
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).
BMW 3 Series
There's a lot that I like about how this performs but a highlight is how eagerly the car responds when you accelerate.
However, it’s not unbridled power. There’s no bucking at the front or shuddering through the steering wheel. It’s controlled but still very fun.
The lower centre of gravity and coupe-like height of this does mean it handles corners well and the bolstered seats hold you firmly into place, meaning you can be free to drive this a little harder than you might normally. Which I did and can confirm it handles itself well.
This has the M Sport suspension, which means it’s stiff, but you feel very connected to the road.
You do get a lot of talk-back from bumps in the road but unless you hit a big pothole, you never feel rattled by them.
But it is a harder ride than other luxury models, which doesn’t bother me as I like the handling, but if you want limo-like comfort, look elsewhere.
The cabin is very nice to spend a lot of time in and relatively quiet, even at higher speeds.
The 11.4m turning circle and sleek dimensions makes it very handy to park, even in tight car parks. The nose is long but the front and rear parking sensors take out any ‘will I make it’ moments and the super clear reversing camera is great.
Safety
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.
BMW 3 Series
The safety list includes a suite of features and the following come as standard: adaptive cruise control, auto emergency braking (operational from 5.0-210km/h), blind-spot monitoring, speed sign recognition, forward collision warning, SOS emergency call button, daytime running lights and rear cross-traffic alert.
I like the intelligent seatbelt reminder and that the bonnet is considered 'active', meaning it will lift up and away from the engine if the sensors detect that a pedestrian has been hit.
However, I have to call out the lane departure and keeping aids. It’s a hit or miss system and I tested it extensively this week once I noticed it.
You can customise the sensitivity levels and even on the highest sensitivity, it works too sporadically for my liking. BMW should improve this system for future instalments.
The 3 Series has been awarded a maximum five-star ANCAP safety rating but it was done a while ago in 2019. It only has seven airbags and is missing the newer front centre airbag.
There are ISOFIX child seat mounts on the outboard seats and three top tether anchor points but the back seat is a bit too narrow to comfortably fit three child seats side by side.
You'll be able to fit a 0-4 rearward facing child seat but may struggle if you're a tall family.
Ownership
Mercedes-Benz E638/10
All AMG models sold in Australia are covered by Mercedes-Benz's five year/unlimited km warranty, with 24-hour roadside and accident assistance included for the duration.
Recommended service interval is 12 months or 20,000km, with pricing for a three-year (pre-paid) plan set at $4300, a $950 saving overall relative to its three year, pay-as-you-go 'Service Solutions' capped price program.
And if you're happy to fork over a little more up-front, there's a four-year service deal at $6300, and five years coming in at $7050.
BMW 3 Series
The 320i comes with a five-year/unlimited km warranty, which is standard for this class.
You can choose between a three- or five-year capped-priced servicing plan. The five-year plan costs just $2150, or $430 a year, which is competitive for this class.
Like other BMWs, servicing intervals are condition-based, with the car letting you know when it needs to be serviced.
