Mercedes-Benz E-Class vs McLaren 720S

What's the difference?

It's nice to see the E-Class still embody the ancestral heritage of Mercedes-Benz, a brand which has had much change forced upon it in the last decade.

This hybrid one in particular does a remarkable job of blending the future and the past in one deeply capable and customisable package, but not one without its flaws.

While the E 300 e manages to unite these elements nicely, it's ultimately held back by its classic rear-drive underpinnings which have consequences for packaging and electric range.

Past McLarens have been accused of being a bit soulless, but this one is alive. The last time I felt like this in a car was a Ferrari F12, one of the scariest but most brilliant cars I've ever driven. Except the 720S isn't scary on the road, just sheer genius.

The 720S doesn't necessarily beat the competition but it opens up new ways of doing supercar things. It's a car that looks amazing, is more than fit for purpose but has a wider range of talents than the others. 

That makes it ever more compelling, both as a piece of automotive brilliance to admire, andl as something to consider when you've got half a Sydney apartment to spend on a car.

Australian roads await, but the drive through rural English country roads and villages was a great preview. All I can say is: gimme one.

The E-Class recently received a significant facelift to bring it in line with the brand's latest design ethos, and it serves to refine an already elegant sedan.

The E-Class isn't just the brand's definition by reputation, but by its look, too. While some may be disappointed by how similar it now looks to the C-Class below, or the S-Class above, giving the core Mercedes sedan range near identical silhouettes, it cuts a unique path from its traditional rivals.

BMW's 5 Series leans into a sharper and more aggressive design language, while Audi's A6 does much the same with a post-modernist edge.

I'd argue the stoic Germanic stare of the E-Class’ softer face places the Mercedes exactly where it needs to be, but it doesn't stray from its sporty rear-drive underpinnings entirely.

The car's new blacked-out highlights accentuate its width, and the 10-spoke alloys on our test car fill the wheelarches and draw your eye to the car's low stance and big brakes.

A classic Benz beltline runs from the front lights to the rear, uniting a tidy and clearly well-built package.

Inside and the more luxury-focused touch of the E-Class compared to rivals is evident. Lavish wood trims work their way through the doors and across the grandiose dash, and while the flashy screen fittings from the wider Benz range are present here, the interior is toned down several notches from the glitz of the brand's smaller vehicles.

This offers it a much more stately ambiance, matched by the synthetic leather ‘Artico’ seats which are more like lounge chairs you sink into.

The overall design links the E-Class with its siblings nicely, and there are a lot of the brand's re-imagined classic touches present, like the circular climate vents, wooden panel inserts, and silver-tinged toggles which run down the centre.

It's not all retro, though, with the E-Class wowing observers with its giant single gloss panel hosting the multimedia suite and digital dash elements.

Obviously, you can go further here, with a long list of optional interior colour and trim combinations to customise the E-Class to your heart's content, although I was happy with the classic black on brown woodgrain of our test car.

The 720S has received mixed reviews but nobody will say it isn't striking. I love it - every designer says their influence is a Lockheed SR-71 Blackbird (designer Melville even jokes about it), but you really can see it in the 720S, especially in the cockpit design, which looks like a glass canopy from that surveillance jet.

McLaren's signature dihedral doors, which go all the way back to the 1994 McLaren F1, are substantial, with a double skin to act as a serious piece of aero kit.

Melville told me in January that he thinks the cars look shaped by nature, using the example of a stone left in a stream to erode. The 720S is full of details evoking that image, with a clean, taut surface. Where everyone complained that the 12C was "designed in a wind tunnel", the 720S looks designed by the wind. In the carbon and aluminium, it looks extraordinary.

One of the most talked about features are those headlights - almost always finished in black, they're known as "the socket". When you get close you see slim LED DRLs, small but powerful headlights, and you then discover two radiators behind them. Follow it through and the air exits through the bumper, around the wheels and then through the door. It's quite something.

Inside is the McLaren we've come to know and love, but with a clever kicker. The dash panel looks lifted from a race car - but with far nicer graphics. Switch to "active" mode, turn everything up to Track and the panel swings down and presents you with a minimised set of instruments to reduce distraction and make up for a lack of head-up display - just speed, get and, revs.

The E-Class takes many forms around the world, and one of them is a taxicab which makes a lot of sense because the E-Class is one of the few cars I've had on test of late that I'd actually like to be driven around in rather than always take the helm myself.

The rear seat space is enormous behind my own driving position, and the detailed luxurious trims continue, complete with the dazzling milled silver speaker fittings, woodgrain trim, and in our test car, rear heated seats.

Again, the seats are ones you simply sink into, and the window is nice and wide for great visibility.

Alongside rear heated seats in our car, amenities include large bottle holders in the doors, flip-out ones in the armrest, hard shell pockets on the back of the front seats, as well as dual adjustable air vents with a lock-off.

The front seats also offer generous space, comfortable and supportive designs, and a lavish space for full-sized adults with a high level of adjustability.

As much as I hate the fact that you have to tick pricey option boxes on an already pricey car, the amenities they afford are properly luxurious.

The seat heating, for example, extends to the armrests in the doors and centre console, and the third climate zone is a necessary touch if you're ferrying around rear passengers often.

While a sedan like this is never going to have the ease of seating of an SUV, there are lots of little areas where this Benz shines.

Proper four-door keyless entry is a nice touch. As is the ability to pre-condition the cabin, the way the doors open nice and wide, and the 40/20/40 split fold of the rear seats allow you to use the centre fold as a ski-port in European style.

Up front, you can customise the digital dash how you see fit, and while the touch panel controls on the wheel and centre console can be clumsy at times, at least there are multiple ways to interact with the system, and a physical dial for volume control hasn't been forgotten.

Over time I've even warmed to the centrally-located touchpad controller. It's easier to use than the one in Lexus products, and it's nice that I have a way to interact with the piano-gloss screen without needing to reach over to it while I'm concentrating on the road (leaving finger prints all over it in the process).

Even things as simple as the car's instruction manual being entirely digitized into the multimedia suite, complete with search function, is just smart.

The layout of the E-Class creates a significant reduction in boot space in this hybrid version, however.

Because it's a rear-drive sedan, it requires the batteries to be awkwardly packaged under the floor and on top of the axle, so the boot floor is an odd, tiered surface, with space reduced from a decent sedan-sized 540 litres (VDA) in purely petrol variants to a hatchback-sized 370L in this PHEV.

As you might be able to tell from the pictures, this shelf arrangement makes the space hard to use, although it did manage to fit our largest (124L) CarsGuide travel case on an angle.

For a supercar, there is a surprising amount of space in the cabin. You can strap 220 litres of (hopefully) soft stuff on the rear shelf behind the seats and there's a 150-litre boot under the nose. You can store your track gear under there, including helmet, or even cram in a few soft bags for a weekend away.

Again, unusually a for a supercar, you're also  treated to a couple of storage cubbies in the centre console.

There's plenty of room in cabin for two bodies and the driver's seat offers lots of adjustment. Despite being so close to the front wheels, your feet have space even for my ridiculous duck feet to fit easily. There's even enough headroom for those over six feet, although the glass portholes in the top of dihedral doors might not be so welcome in an Australian summer.

Kicking off at $489,900 plus on roads, it's fairly clear that the car the local operation has in its sights is the Ferrari 488 GTB, which sells for around $20,000 less but rarely arrives with less than $40,000 in options on board. Two further versions of the 720S are available from $515,080, the Luxury and Performance spec levels, both largely cosmetic.

The 720S ships with 19-inch front wheels and 20-inch rears wrapped in Pirelli P-Zeros. The exterior is finished in "dark palladium" trim and the cabin is lined with Alcantara and Nappa leather. Also onboard is a four-speaker stereo, digital dash, dual-zone climate control, sat nav, active LED headlights, power windows, sports fronts seats and not much else.

A predictably lengthy options list includes paint from $0 to $20,700 (McLaren Special Operations, or MSO, will cheerfully find ways to charge you more for that extra special paint job), but most of the list is carbon fibre bits, reversing camera ($2670!), a $9440 Bowers and Wilkins stereo... you get the picture. The sky, or your credit card, is the limit.

The front lift kit is $5540 and totally worth it to protect the underbelly from driveways. Unlike a couple of Italian rivals, it's not mandatory for all speed-bump ascents.

As we discover every time we look at a car like this, the spec seems slim but none of its competitors have much in them, so it's line-ball.

The E 300 e has a 2.0-litre turbocharged four-cylinder petrol engine producing 155kW/350Nm mated to a nine-speed torque converter automatic transmission, driving the rear wheels.

The transmission contains an electric motor which is capable of producing 90kW/440Nm on its own, allowing full range of motion in the ‘Electric’ driving mode.

It is also capable of hybrid assistance to the petrol motor, making the E 300 e the fastest non-AMG-badged E-Class model to 100km/h, with a claimed sprint time of just 5.7 seconds.

It also has a 13.5kWh lithium-ion battery pack, which is good for a claimed electric-only driving range of 51km (on the more lenient NEDC testing cycle).

It's a complex mix of gear, and the electric range I experienced was certainly less than 40km. In other words, it's used up very quickly.

The Benz offers some interesting driving modes to help with this, which we'll explore later in this review.

The 720S runs a 4.0-litre version of McLaren's familiar flat-plane crank twin-turbo V8. Power is up to 537kW (or 720PS, hence the name) and torque up almost 100Nm to 770Nm, from 678. McLaren says 41 percent of the components are new.

A seven-speed twin clutch sends power to the rear wheels and the 1283kg dry (down 106kg from the 650S) monster hits 100km/h in 2.9 seconds, surely a cautious claim. The more alarming 0-200km/h clam is a terrifying 7.8 seconds, half a second quicker than its closest rival, the 488 GTB. That is seriously, insanely quick, while top speed is equally bonkers at 341km/h.

Instead of a complicated and heavy active differential, the 720S uses the rear brakes and various other methods to get the same effect. It's one of several ideas pinched from F1, some of them now banned.

All of this hybrid gear leads to impressive consumption figures. Officially the E 300 e will consume just 2.2L/100km on the combined driving cycle, with around 13.0kWh/100km of energy consumption worked in as part of that calculation.

However, the hybrid Benz requires 98 RON premium fuel, has a smaller tank (60L) than its all-combustion counterparts, and its claimed 51km of NEDC range is more in the late thirties or early forties in the real-world in my experience.

That said, our car consumed a blend of 5.6L/100km and 8.3kWh/100km in my time with it, which is a nice balance of fuel and energy consumption.

I drove it with a lot of electric mode in the mix, but also had a day solely on the engine, and some experimenting with 'Sport' mode and 'Battery Saver' which is designed to maintain the battery level whilst using hybrid mode where it can.

The E300 e accepts a European-standard Type 2 ‘Mennekes’ charging cable in AC form only. It can charge at a theoretical max speed of 7.4kW, although the max I extracted from my local solar-charged AC outlet was 7.2kW.

It took around an hour and a half to get my E 300 e to about two-thirds charge. It would have charged to 100 per cent in around two hours using this method.

Expect somewhere between four and five hours for it to charge to 80 per cent from a 2.4kW wall socket with the included charger.

The system as a whole works well, but I wish it had more purely electric range. A battery closer to 20kWh would offer 60 or 70km of real-world range for a car of this weight, but would eat significantly more boot capacity.

McLaren claims the European combined cycle could return 10.7L/100km, but we have no way of knowing if that is accurate because we weren't mucking about on the day we had the car.

For all the electrification and evolution in Mercedes-Benz’ greater range, it's almost like coming home to sit in the E-Class.

Not only does the E 300 e stay true to the brand's luxury sedan roots with the comfort and refinement on offer, but it's perhaps the one variant in the E-Class range that makes a significant stride toward the future of the nameplate.

I'm sure we'll see a fully electric version of the E-Class in the near future (the brand is shifting to electric-only with an aggressive timeline), but for now, at this price, hybrid is the way forward for luxury sedan refinement.

The way this car blends its electric and combustion modes is notably smooth, and the engine is so distant it's genuinely hard to tell when it turns on, unlike this car's smaller A 250 e PHEV hatch sibling which takes a major drop in refinement when the rattly 1.3-litre four-cylinder engine needs to be relied upon.

This is likely due to the higher-end nature of the 2.0-litre engine and nine speed longitudinally mounted transmission in a much larger and heavier car. One thing I've never liked about the Mercedes PHEVs (and is a common problem among many PHEVs) is the ‘hybrid’ mode could be a bit smoother and more transparent on how it divides its time between electric and with the engine on. At times it runs the engine at the lights for no reason, and it seems unusually keen to turn it on when it could be using electric power. Perhaps we are spoiled by the simplicity and twenty years of refinement of Toyota's Hybrid Synergy drive, but it has the affect of making you wish every hybrid was as good.

The default ‘Comfort’ mode, while the most forgiving in terms of this car's ride, is weighted toward entirely draining the battery before it uses combustion power. The extra drive modes and customisation this PHEV offers are very useful though. Battery Saver mode lets you rely predominantly on combustion power. It's better to use on the freeway where combustion power is at its most efficient, allowing you to switch back to Comfort or Electric when you're stuck in traffic.

Sport hunkers the E-Class down for a sportier and firmer experience, and it also tweaks the accelerator response and auto transmission for a far more aggressive driving tune. As this mode won't use the electric motor at all, even at low speeds, it can be handy to use it to charge the battery via regenerative braking for times when you might not have access to a charger.

In fully electric mode, the regen braking can be tweaked to the max using the paddle shifters to increase your electric efficiency and range.

Like the smaller A 250 e, it's a highly customisable experience, letting you experience as much or as little electrification as you want in the moment, although in this case it's let down a little by the limited battery capacity.

Still, the E 300 e is an E-Class, quieter and sleeker than before. The ride is as stately as the interior suggests, and even on those 19-inch wheels little noise or discomfort makes its way into the plush cabin. The transmission is as close to an old ‘slush-o-matic’ you can get, and I mean that in a good way. Unless you're in one of the Sport modes, it will never interfere with the experience from behind the wheel.

Once you do awaken it in Sport or Sport + though, it shifts, even via paddles, with a surprising urgency, and it's in those modes where the air suspension transforms the cosy barge-like ride from Comfort or Electric into something far more rigid and responsive.

The dynamic breadth of ability in this car is a reminder of what premium money like this can buy. On the one hand you have the luxury of an economical comfort saloon, and on the other you have at least an inkling of semi-electrified performance at the flick of a switch.

Just remember to plug it in when you get home, or you're lugging around a lot of battery for no good reason.

One of the biggest changes from 650 to 720 is the new Monocage II carbon fibre tub. The drop in overall weight is partly because the cage now includes the windscreen hoop, which previously was metal. Kerb weight with all fluids and a 90 percent full fuel tank (don't ask why 90 percent, I don't know either) it weighs 1419kg, giving it the same power-to-weight ratio as a Bugatti Veyron. Yikes.

The 720S is an astonishing car. We always say you can pootle in a modern supercar, but the 720S is so user-friendly, maneouvreable and so easy to see out of - there are no significant blind spots with an almost entirely glass roof - you can tackle city and country in comfort mode and actually be comfortable. Comparatively, a Huracan goes all blergh in Strada mode and the 488 GTB never stops begging you to kick it in the guts. The McLaren is easy, liveable and smooth. 

I was driving a left-hand drive car in the UK, which should have been a complete nightmare, but it was fine - the vision is excellent, particularly over the shoulder. 

But when you do decide to kick the 720S into action, it's wild. The acceleration is brutal, the handling impeccable and the ride, oh, the ride. No supercar can handle bumps, irregularities and flat out poor surfaces like the McLaren. The 540C's ride is incredible as it is, but the 720 is just wow.

Because it's quite light, the nose goes where you point it, the huge brakes have less to stop, the towering power less to push. The steering in the 720S is well-weighted but has tons of feel - you know what's going on underneath the double-wishbone sprung front wheels and you can adjust what you're up to accordingly. The stability system is excellent, too. Never overbearing or abrupt, where talent ends and the help begins is delightfully blurry.

The new engine is a bit more tuneful than past McLarens - there's even a loud-start party trick - but it's not loud and overbearing. You'll hear turbos whisting, sighing and pshawing, a deep bassy exhaust note and some awesome intake roar. But there's not much off-throttle character. It does at least do away with the histrionics of the Italians.

The only serious drama is the amount of noise bouncing around the cabin over about 100km/h. There's a lot more glass than sound-soaking Alcantara, which explains some of the extra tyre racket over a 650S. You can't have everything, I guess.

Along with a super-strong carbon tub, to which is fitted aluminium crash structures front and rear, the 720S comes fitted with six airbags, stability and traction controls and carbon ceramic brakes with ABS (100-0 happens in fewer than 30 metres).

Mercedes covers all its passenger cars with a five year and unlimited kilometre warranty, beating out its primary Audi and BMW rivals which persist with three-year offerings, and generally out-performing the premium segment.

The E-Class needs to be looked at once every 12 months or 25,000km, whichever occurs first, and like many German automakers, service packages can be bundled in at the time of purchase to bring overall costs down.

In the case of the E-Class, this will set you back $2450 for three years, $3200 for four years, or $4800 for five years, at a claimed minimum saving (three years) of $550 compared to paying-as-you go.

It's not as expensive or as unknown as it used to be here, but at close to $1000 per year, even when purchasing via the pre-paid packs, it's still very much at the premium end.

The 720S comes with McLaren's three-year/unlimited kilometre warranty with roadside assist. McLaren will want to see you every 12 months or 20,000km, which is quite unusual at this level.
