Peugeot 408 vs McLaren 750S

What's the difference?

The Peugeot 408 GT plug-in hybrid features tech that could be improved upon and like all plug-ins, you get the best economy if you regularly charge it and that’s not always realistic. It is a little expensive compared to its rivals but sports a killer design that looks fresh and the cabin is roomy with nice features.

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.

There’s quite a lot happening with the design because of the mash-up of body styles. The long sleek body has sedan vibes but it sits high enough to tag itself as an SUV and the rear has that classic coupe pinching.

It won’t be everyone’s cup of tea but I like it. It's bold and different, which feels like a bit of fresh air in this SUV-heavy market.

The lights also set this apart from its Peugeot stablemates and look more refined, too. You can still see the remnants of the original ‘claw’ design in the tail-lights if you look closely but it's the long vertical DRLs at the front that give the design real edge. They resemble the fangs of a snarling cat (just too cool).

The sophisticated sleekness is extended to the interior where you find a cabin that is flush with high-end materials and soft touch points.

The curved dashboard, high-end tech screens and the mix of Nappa leather upholstery and synthetic leather trims definitely cement its grade position. While not a fan of the green contrast stitching myself, it does create an interesting focal point.

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.

Both rows have ample leg- and headroom for my 168cm height. Even my father, who is 183cm tall, felt comfortable in both rows.

The seats are comfortable and offer enough padding to be enjoyable on a long trip. The heat and massage functions on the front seats make the cabin experience feel refined but the massage function sometimes stops when the heat function is also on.

Individual storage is good for the class with the front getting some centre console storage spots, including a phone shelf, as well as a dual-opening middle console, glovebox and two cupholders. There are also a small storage bin and drink bottle holder in each door.

In the rear, there are directional air vents, two USB-C ports, map pockets and a drink bottle holder in each door but you miss out on cup holders, an armrest and other items you might expect for this grade level, like heated outboard seats or climate control.

The other charging options are solid with the front row getting two USB-C ports, a wireless charging pad and a 12-volt socket. There is another 12-volt socket in the boot.

The 10-inch touchscreen multimedia system looks great and you can customise your ‘buttons panel’ to the features you use most often, which is very clever. However, the system isn’t always responsive which gets very annoying - the seat functions in particular can be laggy.

The system does feature built-in satellite navigation and wireless Apple CarPlay and Android Auto but the multimedia system is too glitchy to truly charm.

The boot features a tyre puncture repair kit, relatively level loading space and 471L of boot capacity, which has been fine for all of my errands this week. You also get a hands-free powered tailgate, which is always handy.

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 408 GT is a front-wheel drive that has an eight-speed auto transmission and is powered by a 1.6-litre turbo-petrol engine and an 81kW electric motor, which produce combined outputs of 165kW/360Nm. It can do a 0-100km/h sprint in 7.8 seconds. 

The switch between the electric and petrol components isn’t always seamless and you can feel some shudders as it flips between them at lower speeds but the power feels adequate for everyday driving.

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.

The official combined cycle fuel consumption figure is 1.5L/100km but that’s if you were recharging the car every time the electric range dropped out.

My real-world consumption sat at 5.5L after a mix of open-road and urban driving. I only charge it every other day as that’s realistic for my family life but like all plug-ins - you will get the best efficiency if you charge it regularly.

The 408 GT has a Type 2 charging port and a small 12.4kWh lithium-ion battery that can accept up to 3.7kW of power. You get up to 60km of pure electric driving range (but I only saw a top of 38km available) and on a domestic socket, you can go from zero to 100 per cent in around six hours.

On a 7kW or 11kW AC power charger, that drops to three and a half hours. So, it’s a tad slow to charge but worth it if you can leave your car on charge overnight.

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.

The 408 GT has more than enough power to be a comfortable open-roader. You can keep your speed consistent on hills and it has enough gumption to cross traffic quickly in an urban environment.

Steering is responsive and the car is easy to manoeuvre in close quarters but the lane-keeping aid does severe corrections, so have your wits about you when you’re on the go because it can be a fright when the wheel starts fighting you.

With the ride comfort, there can be vibrations through the seats and steering wheel depending on the road surface and you’ll know about it when you hit a bump. It’s okay enough to not be classed as rough but it’s not as refined as you'd hope.

Despite the narrow rear window, the visibility is actually very good and it’s easy enough to park but the 180-degree camera system needs work.

You'll end up using the straight reversing camera because you need to ‘drive’ over the space for an image to pop up for the '180-degree' view and by the time it does, you’ve parked anyway!

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 408 comes with a usual warranty term of five-years/unlimited km and the battery is covered by an eight-year or up to 160,000km warranty.

You can pre-purchase three, four, or five-years worth of services, which all work out to be cheaper than the pay-as-you-go option. It costs $1200 (three-years), $1700 (four-years), and $2000 for the five-year plan.

On the five-year plan, services average $400, which is reasonable for the class. Servicing intervals are also good at every 12 months/15,000km, whichever occurs first.

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.
