BMW 3 Series vs McLaren 750S

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.

Not just a love letter to the intoxicating delights of the mighty V8 engine, the McLaren 750S is a genuine joy across the board.

Note: CarsGuide attended this event as a guest of the manufacturer, with travel, accommodation and meals provided.

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!

McLaren concedes the cosmetic updates for the 750S are “relatively subtle”, but there have been some key changes.

The front bumper and splitter are new, as is the rear bumper, while the rear wing is now bigger, with 20 per cent more surface area.

Also at the back, a new (and lighter, of course) stainless steel exhaust is now centre-exit, rather than off to either side.

Like the 720S before it, the 750S looks more like a statement of intent than a designer’s dream, with aerodynamic function over form the order of the day.

In the cabin, you’re looking at two sports seat, a grippy Alcantara steering wheel, and two relatively small screens by today’s sizeable standards.

You can have your cabin trim in full Nappa leather, or the leather mixed with Alcantara, and the audio is taken care of by Bowers & Wilkins.

Still, the 750S delivers everything you need and nothing you don’t in a car in this category.

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.

Next question, please. This is a stripped-back, lightweight, two-seat supercar designed to get you to, and then around, a corner in the least amount of time possible. So, no, you can’t fit much in the way of grocery shopping in the back.

You can, however fit a total 150 litres (front) and 210 litres (rear) in the 750S, and it gets bonus points for having deep cut-outs in the roof that make slipping in under those scissor doors far easier than you might expect.

The McLaren 750S can be yours in hardtop ($585,800) or drop-top Spider ($654,600) guises, both of which have travelled north from the pricing applied to the 720S, which was $489,900 at launch, and its Spider equivalent, which was $556,000.

What you’re getting, though, is more — and less— of everything. More power, more performance, more downforce and more stiffness, combined with less weight, with McLaren having taken a forensic approach to stripping kilos from the 750S.

What you're not getting, though, is much in the way of niceties, with the McLaren 750S offering less interior tech and comforts than a mid-range hatchback (“it now has Apple CarPlay,” they exclaimed excitedly).

But for mine, that only enhances the drive experience, with the 750S offering a genuinely pure-feeling drive — a steering wheel free of buttons, a cabin largely free of distractions, no safety chimes bonging, and a nuclear reactor attached to your right foot. These are all good things.

Elsewhere, the McLaren 750S rides on ultra-lightweight forged alloy wheels (19-inch front / 20-inch rear) wrapped in Pirelli P Zero rubber as standard, and there are thinly cushioned carbon-fibre-shelled racing seats that hold you snuggly in place, and are every bit as comfortable on bumpier roads as cuddling a cactus.

In the cabin, McLaren has worked to up the tech, though its best to remember this is pared-back over plush.

A steering column-mounted driver display is new, and delivers all your key driving info, and it’s framed by all your go-to switches, like your 'Drive Mode' options. 

In the centre, an 8.0-inch portrait-style screen now has Apple CarPlay as standard (but not Android Auto), and there are USB-C and USB-A connections for your devices, too.

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.

Ah, now we’re talking. In the huge-displacement world of supercars, a 4.0-litre twin-turbo V8 might sound a little on the small side when put up against V10s and V12s out of Italy. 

But this mid-mounted, twin-turbo powertrain perfectly compliments the overall balance of the 750S, and when its 552kW and 800Nm (fed through a seven-speed automatic) meets the lightweight McLaren, the results are staggering.

The zero to 100km/h dash is dispatched in 2.8 seconds, while 200km/h flashes by in 7.2 seconds. Want to push to 300km/h? You’ll need just 19.8 seconds.

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 says you can expect 12.2L/100km on the combined cycle, with emissions pegged at 276g/km. But you can also expect to win the lottery. It doesn’t make it likely.

It’s hard to imagine how softly you’d have to treat the 750S to get anywhere near those numbers, but I know you almost certainly won’t. The temptation is simply too great.

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. 

Usually we wouldn’t be dedicating much space to the kilogram’s shaved here and there off the total weight of a vehicle, but it’s important in this case.

In the 750S, that starts with a bespoke carbon-fibre monocoque platform, which is not only light, but also so inherently stiff that even chopping the roof off for the Spider version required no extra bracing or supports, and only marginally impacts the performance figures.

Then, there are the lightest alloys ever fitted to a series McLaren, which reduce unsprung weight by up to 14 kilos.

That rear wing isn’t just bigger, but also lighter, saving another 1.6 kilos, the carbon-fibre-backed seats save a whopping 17.5kg, the new suspension springs shave another two-or-so kilograms. The list goes on and on.

All up, they've found 30 kilos between 720S and 750S, which is now 1389kg total.

The result is a vehicle that feels endlessly athletic — light, lithe and perfectly balanced — but also one that, when you’re feeding on that endless power, feels as though it might suddenly take flight.

Flat-footed acceleration is laugh-out-loud fun, the tyres scrabbling for grip with each donkey-kick gear shift, even past 100km/h, with the rear end shifting around slightly as the Pirelli rubber deals with the physics of what’s happening. It’s loud, visceral and intoxicating, and you absolutely never tire of it.

But the magic in this McLaren is that it's more than just brutally fast in a straight line, it's also one of the most engaging vehicles I've ever driven, and one that provides a near-telepathic connection to the car, its tyres, and the tarmac below.

The more time you spend behind the wheel, the more tameable it feels, and even at warp speeds (somewhere above 270km/h), you feel connected and in control, owing mostly the open lines of communication between the tyres, the steering and the driver.

Also ferocious is the McLaren's braking force, combining carbon ceramic discs with a rear wing that doubles as a jet-style air brake, and stamping on the brake pedal produces vision-blurring force that leaves you feeling like you're not just stopping, but hurtling backwards through time.

So, race track, tick. But away from it, the McLaren – with its 'Proactive Chassis Control' hydraulic suspension – is surprisingly compliant when you want it to be, with its 'Comfort' drive mode delivering exactly that, softening the important bits so you don’t rattle yourself to death on the freeway.

If the 720S was a benchmark, then this 750S is something else entirely, shifting the needle in every important way to create a vehicle that sparks pure, unadulterated joy from behind the wheel.

Safety systems hardly abound here, and nor is McLaren or ANCAP likely to pony up for the 750S for crash testing.

You do get front and front-side airbags, front and rear parking sensors and a reversion camera, as well as a handy nose-lift function which should stop you scraping over steep speed bumps and the like.

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 750S is covered by a standard three-year, unlimited-kilometre warranty, which is fully transferable.

Owners can also spring for an extended warranty, which can cover the McLaren for up to 15 years.

Servicing is required every 12 months or 15,000km.
