BMW 3 Series vs McLaren 720S

What's the difference?

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.

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.

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!

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.

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.

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 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.

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.

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!

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.

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. 

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).

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.

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.
