BMW 4 Series vs Mercedes-Benz E220

What's the difference?

The BMW M440i xDrive Gran Coupe manages to combine sleek design with a fun-to-drive personality and surprising practicality. It’s a rapid premium, four-door, five-seater offering extra flair, and in this part of the market, good value. But more than anything else it’s got a cracking in-line six under the bonnet.

Given Mercedes-Benz's rich heritage with station wagons, it is a bit of a shame Australia’s preference for SUVs has reduced the line-up to just one variant this time around.

I'm glad they've picked the All-Terrain to fly the flag though, and Merc wagon loyalists should appreciate the extra versatility of its dirt road ability - if they're not mourning the loss of the extra two seats in the rear. Like the rest of the current E-Class range, the E 220 d All-Terrain is an excellent product overall.

So, how does this four-door 4 Series differ from a four-door 3 Series? The answer is as plain as the nose on this car’s face.

BMW’s head of design, Adrian van Hooydonk, has been expanding the brand’s signature ‘kidney grille’ in every conceivable direction, and this is the much talked about interpretation adorning all 4 Series models (petrol, hybrid and electric) as well as the M3 sedan.

The new Gran Coupe is longer, wider, and taller than the outgoing model, and the track is broader, front and rear. The wheelbase has also been extended, now a whole 5.0mm longer than the 3 Series.

The DRLs and headlight main beams are LED with laser high beams, immense gills square up the edges of the front clip, while a vent and the strake attached to it stand the car apart. Plus, of course, the doors are frameless. 

One niggle, though. I’m not in love with the slender door handles. It’s hard to get a good grip on them, especially in the wet. 

Standard 19-inch alloy rims are shod with Pirelli P Zero rubber 245/40 fr / 255/40 rr), the roofline slopes distinctly towards the rear, a lip spoiler on the trailing edge of the tailgate is classic BMW, darkened LED tail-lights wrap around the rear corner, and a diffuser-type panel is flanked by large exhaust apertures.

Our car’s ‘Aventurine Red’ finish is a $3850 option, but to my eyes anyway it looks superb.

Exterior trim including the grille frame, front air intake inserts, mirror upper housing, model designation badges, and tailpipe are finished in ‘Cerium Grey’, which I reckon 99.9 per cent of people will see as black. 

The interior will be familiar territory for any current BMW owner, the 12.3-inch digital instrument screen sitting in a compact, hooded binnacle, and partnering with a 10.25-inch multimedia display standing proud of the dash above the broad centre stack. 

The seats are trimmed in top-shelf leather with blue contrast stitching, plus the grippy sports wheel is also wrapped in genuine hide.

BMW calls the finish on the main buttons and controls ‘Galvanic’ which translates to a slick silver metallic look and feel. Configurable ambient interior lighting is a nice touch, and the broad console enhances the driver-focused feel, with a sprinkling of carbon-fibre around the centre console and dash lifting the sense of occasion.

Overall, the interior feels clean and classy with an obvious attention to detail.  

The All-Terrain styling pack is comprised of tough-looking front and rear bumpers, with unpainted plastic side skirts and wheelarch flares on all corners. This will all be welcomed by anyone who travels regularly on dirt roads, but the All-Terrain bits will also provide a handy disguise from urban parking scrapes.

The double-blade grille, wheels and roof rails are also bespoke to the All-Terrain, and the net result is a distinct personality that should satisfy the majority of previous E-Class Estate buyers previously opting for the AMG styling pack.

Interior trim is based on the regular E-Class Avantgarde package, but with specific rubber studded pedals and All-Terrain branded floor mats to align with the exterior treatment.

In the default suspension setting, the All-Terrain sits 29mm higher than a regular E-Class. Taller tyres make up 14mm of this, while the remaining 15mm is thanks to an elevated 'Air Body Control' air suspension. A further 20mm of lift is available with the All-Terrain drive mode selected, but only at speeds up to 35km/h.
 
The All-Terrain’s 20-inch alloys are a staggered fitment with 245/40 tyres up front and 275/35 at the rear, while taller-sidewalled 245/45R19 at each corner are a no-cost option, and essential if you wish to use snow chains.

Like the Estate available internationally, the All-Terrain rides on the same 2939mm wheelbase as the E-Class sedan but gains an extra 24mm in rear overhang to measure 4947mm overall.

The wagon body, extra kit and all-wheel drivetrain also add an extra 240kg to the kerb weight over the E 220 d sedan, with the All-Terrain tipping the scales at 1920kg.

At close to 4.8m long the 4 Series Gran Coupe is a sizeable machine. Up front, the feeling is airy and comfortable, and the rear is surprisingly spacious, especially in light of the car's sloping roofline.

At 183cm I have to fold myself tightly to fit under the low roof, but once inside I have enough room to sit behind the driver’s seat set for my position with more than enough legroom and adequate headroom. Put three full-size adults across the back row, though, and there will be breathing difficulties.

Kids will be fine, however, and individual vents with adjustable temp in the rear was a big plus during a particularly hot test week.

For storage there are generous door bins in the front with room for large bottles, a decent glove box, dual cupholders in the centre console, a reasonable lidded bin (which doubles as a centre armrest), and the wireless device charging bay (forward of the gearshift) makes a handy oddments space when not in use.

In the rear, again the doors feature pockets with room for (medium-size) bottles, there’s a fold down centre armrest with two cupholders, but thanks to the one-piece shells on our test car’s optional M Sport front seats there are no map pockets.

Power and connectivity runs to a USB-A socket and a 12V outlet in the front centre console, as well a USB-C port in the front storage bin, a pair of USB-Cs in the rear, and a 12V outlet in the boot.

Speaking of which, lift the tailgate and with the rear seat upright we were able to fit all three of our suitcases or the beefy CarsGuide pram into the healthy 470-litre (VDA) boot space.

Lower the 40/20/40 split-folding rear seat down and 1290 litres of volume is at your disposal. Plus there are handy bag hooks and tie-down anchors to help secure loose loads.

You can also tow a braked trailer up to 1.8 tonnes (750kg unbraked), but don’t bother looking for a spare of any description, a repair/inflator kit is your only option.

Aside from the All-Terrain’s rugged looks, the greatest departure from E-Class Estate tradition is the omission of the third row of seats, which makes this one a strict five-seater.

One could argue that the Estate’s traditional rearward-facing third row is a bit old school next to the forward-facing setup used by seven-seat SUVs like the GLS, but it's a shame given the third row is still available in other markets.

The All-Terrain does offer a vast cargo area however, with an extra 130 litres (VDA) over the sedan with the seats up to total 670 litres (VDA). Seats down, this extends to 1820 litres (VDA), but it’s worth noting that both wagon figures are marginally smaller than the previous Estate’s 695/1950 measurements.

Facilitating full use of this space is the classic Merc Estate retractable cargo net, and a 670kg payload promises good scope for loading beyond a full passenger count. The air suspension will also automatically maintain a level ride height regardless of load.

As with all current E-Classes, there are bottle holders in each door plus two cupholders front and back and ISOFIX child seat mounts in the outward rear positions.

As per the non-AMG Mercedes passenger car norm, run flat tyres take the place of a spare tyre, but a space saver can be optioned to sit above the boot floor.

The All-Terrain theme follows the same path taken by key rivals Audi and Volvo with the A6 Allroad ($112,855) and V90 Cross Country ($99,900), which leaves BMW’s upcoming 5 Series Touring as the sole option in this segment not to adopt the semi-SUV look.

The $109,900 Mercedes is priced right between the Audi and Volvo, but note that the Audi brings a more powerful V6 to justify its slight premium.

The All-Terrain is available with a V6 internationally, but the 220 d four-cylinder diesel was selected for Australia as it's the closest match for the E 250 d that proved the most popular variant last time around.

Compared with a similarly specified E 220 d sedan (which kicks off at $92,900), Mercedes reckons they're about the same on price, but the All-Terrain throws in the wagon body and all-wheel drive pretty much for free. The All-Terrain also offers a significant value improvement over the previous E 250 d Estate which bowed out at $107,900.

Key inclusions for the All-Terrain over the already opulent E-Class are genuine leather trim, proximity unlocking, widescreen dash instrument that spans two thirds of the cabin, LED 'Multibeam' headlights, underbody protection and 20-inch twinned five-spoke alloys.

Under the bonnet is BMW’s (B58) all-alloy 3.0-litre twin-scroll turbo intercooled, in-line six-cylinder engine, driving all four wheels via an eight-speed automatic transmission and electronically controlled clutch pack, as well as an electronic limited-slip differential at the rear.

It features high-pressure direct-injection and BMW’s ‘Valvetronic’ system managing air flow to the intake side, to produce 285kW at a relatively high 5800-6500rpm. But the big punch is 500Nm of peak torque from just 1900rpm all the way to 5000rpm.

The M440i is also a mild-hybrid with a 48-volt starter motor-generator and supplementary battery able to give an 8.0kW kick at low engine speeds.

The All-Terrain’s excellent 2.0-litre turbo-diesel engine and nine-speed torque converter auto are carried across from the E 220 d sedan, which produces a decent 143kW/400Nm. Max torque is available from 1600-2800rpm.

The All-Terrain is the only Australian E-Class to pair this engine with the '4Matic' all-wheel drivetrain though, which uses a slightly rear-biased (45/55) torque split in this application.

BMW’s official fuel economy figure for the M440i xDrive Gran Coupe, on the ADR 81/02 - urban, extra-urban cycle, is 8.2L/100km, the 3.0-litre turbo six-cylinder emitting 187g/km of C02 in the process.

Stop/start is standard, and we saw an average of 11.1L/100km over city, B-road and freeway running during a week with the car.

With the 59-litre tank brimmed (with minimum 95RON premium unleaded) that real-world test number translates to a range of around 530km.  

The All-Terrain’s extra 240kg and no doubt less slippery body add 1.6L/100km to the E 220 d sedan official combined fuel consumption figure, but the wagon’s 5.7L/100km claim is still very impressive for a taller body nudging two tonnes. 

At this rate, the E-Class All-Terrain has a theoretical range of 1157km from its 66-litre fuel tank.

BMW says the M440i xDrive Gran Coupe will accelerate from 0-100km/h in 4.7sec, and I reckon the threshold for a properly quick car is sub-five seconds.

The 3.0-litre turbo six develops its peak power of 285kW between a relatively lofty 5800-6500rpm, but the big number is a solid 500Nm punch of pulling power delivered between 1900-5000rpm.

Squeeze the throttle pedal pretty much anywhere in the rev range and the response is glorious. Rapid acceleration accompanied by raucous engine noise and rorty exhaust note (albeit with some synthetic support). Various pops and bangs in the Sport settings add extra entertainment.. 

The eight-speed auto gets some electric support from the mild-hybrid system to fill the torque gap on up shifts, and the result is a conventional torque-converter transmission that behaves like a dual-clutch.

Shifts are seamless in general driving, and satisfyingly quick in a more aggressive mode, the wheel-mounted paddles dialing up the fun in manual changes. 

Suspension is double wishbone front and multi-link rear with the standard ‘Adaptive M Suspension’ built around an adaptive damper set-up.

The change between the ‘Comfort’ setting to the ‘Sport’ or ‘Sport+’ calibration is close to instant and makes a discernible difference, especially in terms of ride comfort.

I found the best ‘Individual Sport’ arrangement to be damping in Comfort, with the steering engine and transmission in Sport. The car flows so beautifully through corners with urgent response from the powertrain.

By all means dial up the suspension if you’re having a real crack, but the car feels superbly balanced, stable and predictable in Comfort (front to rear weight distribution is 50:50).

The electrically-assisted variable-ratio steering is nicely weighted with good road feel, and the grippy sports steering wheel is a nice point of contact.

The xDrive AWD system’s default setting is rear-biased, although it will push most of the drive forward when required. But the RWD feel is unmistakable. 

The M440i weighs in at around 1.9 tonnes but feels lighter and more nimble than that figure would typically indicate.  

A standard electronically-controlled M Sport limited-slip differential puts the power down confidently. I have a favourite LSD test corner on my regular evaluation drive, a sharply twisting and rising left-hander.

Rolling into it in a low gear before planting the throttle mid-corner, the car simply hunkers down without a hint of fuss (or traction loss) as it rockets out the other side.

Optional M Sport front seats ($2000) provide comfort and firm location in equal measure and in terms of ergonomics BMW knows how to focus on the driver and set-up an efficient environment. Key controls are perfectly positioned and simple to operate.

I have an issue with the ‘Lane Departure Warning’ function, however, which is too quick to intervene and overly intrusive when it does so. I turned the ‘Steering Intervention’ function off. You can dial down steering wheel vibration warnings, too.

The standard M Sport brakes feature big vented rotors front and rear, with fixed four-piston front calipers doing the bulk of the work. They’re strong but don’t bite or release too aggressively. It’s easy to grease in a smooth application. 

Climbing aboard the All-Terrain, there’s a sense you're seated higher than its 29mm static ride height lift suggests. It's probably mostly psychological, and borne from the All-Terrain styling treatment, but something SUV fans will probably appreciate.

Otherwise it's mainly W213-generation E-Class from the driver's seat, which is a very good thing.

However, the extra 240kg of Estate body and All-Terrain spec over a regular E 220 d sedan is just enough to put a dent in the 2.0-litre diesel's performance. Mercedes claims an 8.0sec 0-100km/h figure, which is still more than enough to keep up with traffic, but just not as spritely as the sedan’s 7.3sec figure.

The combination of airbag suspension and the All-Terrain’s slightly taller tyre sidewalls help the wagon ride commendably well. There's no disguising the large-diameter 20-inch wheels over sharp potholes, but the experience is generally even better than we recall from any other existing E-Class.

The steering also feels slightly heavier, as though the level of assistance has been tuned for a touch more weight to add to the All-Terrain’s semi-SUV aura. If our perception is correct, it only adds to the sense of substance from the driver’s seat.

Its overall composure is maintained on dirt too, with the All-Terrain’s Victorian launch route offering a good dose of gravel and muddy unsealed roads. The all-wheel drive system keeps you pointing where you want and enables clean acceleration from the greasiest of corners. All of this highlights the All-Terrain’s potential as a ski field chaser.

We also detoured via some moderate fire trails, which gave us the chance to try the All-Terrain driving mode that lifts the suspension an extra 20mm and slackens the stability control and ABS to better suit low grip scenarios.

At speeds above 35km/h it reverts to Comfort mode, but will return to All-Terrain settings if you slow down again. In Sport mode or above 125km/h, the suspension lowers 15mm below normal to reduce aerodynamic drag. Even at full height it won’t challenge a GLE for clearance, but it’s significantly more capable than regular E-Class models.

Like all versions of the current E-Class, the All-Terrain carries the maximum five star ANCAP and EuroNCAP safety ratings. A brilliantly integrated suite of active and passive safety features represents the forefront of occupant and pedestrian protection, which goes well beyond its AEB, nine-airbag count, 360-degree parking cameras, rear cross-traffic alerts, and a pedestrian-protecting active bonnet.

These systems work in harmony to enable semi-autonomous driving, which is perhaps the greatest technical advancement of cars since we stopped riding horses.

The M440i Gran Coupe is covered by BMW’s three-year/unlimited km warranty (including paintwork), as well as 12-year/unlimited km anti-corrosion (perforation) cover. 

That’s off the premium market pace now with Genesis, Jaguar, and Mercedes-Benz at five years/unlimited km and Lexus set to join them from January 1st, 2022. 

That said, roadside assistance is provided for the duration of the main warranty, but it’s worth noting “rattles and squeaks” are only covered for one year.

Service is condition-based, the car telling you when maintenance is required, and a range of service packages are available. The basic plan covering a 4 Series for five years/80,000km comes in at $1750. 

The E220 d All-Terrain is covered by Mercedes’ three-year, unlimited kilometre warranty, with service intervals pegged at either 12 months or a generous 25,000km.

Mercedes is yet to confirm capped service pricing for Australia, but we don’t expect the All-Terrain to stray too far from the $556, $1112 and $1112 figures applied to the E220 d sedan’s first three services.
