McLaren 720S vs Mazda MX-5

What's the difference?

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.

Ultimately, the design and tech changes to the ND MX-5 will be the biggest day-to-day advantages of the updated model, because the mechanical changes don’t make themselves hugely obvious on the road.

If you’re into track days, it’s still a satisfying car to hustle as fast as you can, but it’s at its most accessible on winding roads for weekend drives, where the new differential and track DSC mode won’t come into play as much.

But in a world where accessible sports cars are becoming a rarity, there’s only one rear-drive convertible with a sticker price appropriate for financial mortals, and it’s a pretty damn good thing that it’s the ND MX-5.

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

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.

Alright, we’ve all seen ND MX-5s, you don’t need me to tell you about its proportions or explain its design elements to you in too much detail, so I’ll give you the headline changes.

At the front and rear are new pairs of LED head- and tail-lights, respectively… obviously, fitting into the spaces the old ones took up.

The DRLS and reverse lights have come off the bumpers for both, and are now part of the main lights at each end - no more DRLs in the front bumper, and the reverse lights have been replaced by reflectors.

There are new 17-inch wheel designs for the base and GT trim levels, too, and there’s a new colour - Aero Grey.

Inside, it’s a shame that the tan Nappa leather interior of the RF Black Roof can’t be had in a manual roadster, because it’s gorgeous, even though the inside still looks refined enough for a simple sports car in its base cloth trim.

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.

One thing Mazda has significantly changed for the ND is the multimedia screen, now a larger 8.8-inch touchscreen running Mazda’s updated software.

It brings the MX-5 up to date without sacrificing simplicity and makes it a little easier to use. The physical dial and buttons for controlling the screen also remain. The USB-C ports are also new.

Oh, and the MX-5 is the first Mazda model to get Connected Services, which is coming to other Mazda models eventually.

Connected Services allows owners to find, lock, and get alerts for their cars from a phone app, even letting them set curfews to notify them if the car is started during certain hours.

Aside from that, another small tweak is the simplified instrument cluster, which aims to be easier to read even when the roof is open and the sun is bright.

The cabin isn’t built to be plush, it’s built for ‘Jinba Ittai’, Mazda’s philosophy that applies most strongly to the MX-5 which means ‘horse and rider as one’.

And trust me, you feel one with the horse- er, car, when there’s not ample room to move. It’s not restrictive, but it’s cosy. 

Everything’s quite well-placed and it’s not busy with buttons or features in here though, it’s made for focusing on driving. 

One downside is the lack of storage, not even a glovebox, in front of the passenger, and the central storage spot under where your elbow sits is tiny, good for keeping the key fob snug though. Also, the cupholders are able to be removed or swapped between the space behind your elbow, or above the passenger footwell.

There’s also a small storage space between the seats behind where your elbow would sit, though it’s tricky to access while you’re driving.

Then there’s the boot, which is usable for a small amount of luggage at 130 litres in the Roadster and 127L in the RF hardtop.

Finally, as a huge positive, probably the biggest advantage of the ND over any other convertible is how easy it is to open and close the roof in the Roadster. You can do it single-handed, which is great if it starts raining and you’re at a traffic light or able to quickly pull over.

The RF hard-top has a switch that automatically opens and closes the roof section.

Getting into an MX-5 is now a little more expensive, with the base manual Roadster up by $2310 to now start from $41,520 before on-roads.

The top-spec soft-top GT RS is now $51,640, or $2800 more than before.

Pricing for the RF hard top is also similarly bumped up, a base manual costing $46,250, and the most expensive GT RS at $56,140.

There’s also a Black Roof edition which comes with tan Nappa leather inside, but that’s only available in an automatic RF, which is possibly the biggest downside to the 2024 range.

Base models get cloth seats, while GT and GT RS models get heated leather seats. The GT RS also comes with stiffer Bilstein dampers, Brembo front brakes, a bracing strut between the front suspension towers and a DSC-Track mode. The difference there is noticeable, so it's worth the extra spend for the more keen driver.

The higher overall costs bring updated tech, a new 8.8-inch touchscreen and a new limited slip-diff in manual versions, plus tweaked mechanicals like improved acceleration response and lower steering rack friction.

But they do look a tiny bit different too.

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.

Up front, you get one option: a 2.0-litre naturally aspirated four-pot. It makes 135kW and 205Nm, and it’s a delightful little thing, driving the rear wheels only - as it should.

It used to be that the smaller 1.5-litre engine was the more revvy, keen option, rest its soul, but Mazda updated the 2.0-litre to be more eager (and deliver more power) at high revs and basically made the little 1.5-litre redundant.

Anyway, you can have it with a six-speed manual in any variant, or a six-speed automatic in GT guise if you find manual gearboxes difficult or a hassle.

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.

Mazda says the MX-5 uses 6.8L/100km as a manual Roadster, or 7.0L/100km with an automatic gearbox. Or, in the heavier RF 6.9L for a manual and 7.2L for auto.

Not great for a tiny car like this, but pretty good for a sports car!

It’s got a 45-litre fuel tank, takes premium 95 RON or higher, and while it should hypothetically be able to travel more than 600km with its on-paper claims, expect fuel use to sit closer to 8.0L/100km if you’re driving it anything like it deserves.

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.

It feels like every motoring journo under the sun (literally if the roof is off) owns or has owned an MX-5 of some sort.

And the first time you drive one, you might understand why. 

If you spend your days testing and driving a bunch of different cars that aim to be many things at once, it’s refreshing to drive something that aims to be one: fun.

That’s it, the MX-5 feels like it was built to be fun. Not for convenience, not for power, certainly not for the school run.

And fortunately its simplicity remains with this update. All Mazda has done to change the way it drives is attempt to improve the rear limited-slip differential and improve the steering a little by reducing friction in the rack, as well as improve throttle response.

Has any of that changed the way it feels to drive on-road? No, not massively, but the ND was already such a delight that Mazda could have kept this update to purely design and interior tech changes and it would have still been one of the best-value buys around in terms of fun.

The MX-5 still feels relatively softly sprung while still being a dynamic and communicative sports car that’s engaging to drive even at low speeds, and rewarding (or frustrating) to drive fast.

On tight, winding roads, the MX-5 is at home, its soft suspension keeps you humble with its shifting weight and its relatively meagre outputs keep your licence safe.

In fact, despite being slightly compromised as a daily drive, the MX-5 is still plenty of fun even in traffic, there’s something about the satisfying click as the shifter slips into gear, or the little rev matches heading back down through the cogs when approaching a red light.

The 2.0-litre four-pot is a keen unit, and the six-speed manual is light and easy to work with, plus its steering is light without sacrificing road surface feedback - that feedback can quickly turn into cabin noise on a coarse highway which could become a little irritating on a long trip.

But the MX-5 can still be plenty of fun on track, where you’re more likely to get the most out of its new limited-slip differential and Track DSC mode.

It’s equally frustrating and satisfying to hustle the MX-5 around the East Circuit at The Bend in South Australia, where the track is twisty, busy, and unforgiving. Get it wrong, and the MX-5 lurches or slides to let you know you’ve made an error. 

Get it right, however, and the little roadster glides through the corners, camber changes and even over apex kerbs smoothly and carrying impressive speed.

Plus, the electronic assistance won’t usually kick-in until you really need it, a welcome change from cars that are constantly trying to keep you from having fun behind the wheel.

The ND MX-5 actually scored five stars with ANCAP back in 2016, even though its score has now expired. It’s not obvious how well it would fare under newer, stricter tests, given the small car’s lack of advanced driver assistance - not that that’s a bad thing in the case of a sports car.

Still, for a two-seat convertible, the MX-5 has a decent list of kit to keep you safe including front and side airbags, alerts for driver attention, blind spots, lane departure and rear-cross traffic, parking sensors and a reversing camera, belt pretensioners and side-impact door beams and even automatic Smart City Brake Support.

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.

Mazda’s five-year, unlimited km warranty covers the MX-5, including five years of roadside assist.

Servicing costs are pre-set, with intervals every 12 months or 15,000km up to seven years or 105,000km. They cost between $447 and $638, averaging out at about $544 each.
