Infiniti Q50 vs Maserati Granturismo

What's the difference?

The Q50 Red Sport is a premium sedan that's great value, with a cracker of an engine. While Infiniti has improved the ride and steering, it still feels to me that the engine is too powerful for the wheels and chassis to handle. But if you're looking for something of an untamed beast, this car could be for you. Just don't say we didn't warn you.

There’s a famous line in a Hollywood movie that somebody’s ego is writing cheques their body can’t cash.

In the GranTurismo’s case, its agility, performance, ride, handling and overall refinement means it absolutely delivers on the promise of the stunning styling.

Of course, this review is a first taster only, even if it is on one of the most challenging race circuits we know. And, as such, we cannot wait to finally drive the GranTurismo outside on Australian public roads.

Which, by the way, will be all the more beautiful because of it.

The Q50 Red Sport looks cranky from front on, which I like in a car. Yes, the grille is simplistic and gaping, the nose is a bit bulbous, and sure, side on the car looks like a Lexus IS 350, but those rear haunches and the aggro body kit with its front splitter and boot lid spoiler make for an impressive looking four-door sedan.

The update brought restyled front and rear bumpers, those red brake calipers and the dark chrome 20-inch rims and new LED tail-lights.

Inside, the cabin is an asymmetrical paradise (or hell, if you're a bit OCD like me) full of sweeping lines, angles, as well as different textures and materials.

The red stitched quilted leather seats are an addition that came with the update, so is the new steering wheel and the ambient lighting.

The 'Sunstone Red' colour of our test car is also a new hue which looks a bit like Mazda's Soul Red. If red is not you, there are other colours – hope you like blue or white or black or grey because there's 'Iridium Blue', 'Midnight Black', 'Liquid Platinum', 'Graphite Shadow', 'Black Obsidian', 'Majestic White' and 'Pure White'.

The Q50 has similar dimensions to the IS 350: both are 1430mm tall, the Infiniti is 10mm wider at 1820mm,  120mm longer at 4800mm, and has a wheelbase that's 50mm longer at 2850mm.

With a long bonnet and centralised, cab-backward silhouette, the new GranTurismo is built on a highly-modified version of the Stellantis Group’s Giorgio platform, which debuted with the BMW 3 Series-sized Alfa Romeo Giulia sedan back in 2016 and also underpins the Stelvio SUV. 

In this application, it has been redesigned as a modular architecture to accommodate, among other things, electrification. The resulting Folgore (Lightning) electric vehicle version will arrive in Australia during 2025.

Compared to before, the design is all-new, with a body that is slightly longer and wider than before; it features over 65 per cent aluminium, weight distribution is 52/48 per cent up front/rear, and the aerodynamics are honed to maximise efficiency, especially for the Folgore. The latter’s drag coefficiency of 0.26 – 0.02 better than the Modena/Trofeo.

Here are the key dimensions: 4959mm long (+78mm), 1957mm wide (+42mm), 1353mm tall (same as before) and 2929mm wheelbase (-20mm).

Maserati claims it invented the grand tourer with its post-war A6 1500 coupe of 1947. Since then, a variety of timeless designs have been released, with beauty always being the priority… and the GranTurismo nails it.

The Q50 Red Sport is a five-seat four-door sedan and is vastly more practical than its two-door Q60 Red Sport sister, in that I can actually sit in the back seat. The Q60's coupe styling looks amazing, but the sloping roofline means headroom is so severely limited that it reduces the rear seats to a place to throw your jacket.

True, I'm tall at 191cm, but in the Q50 Red Sport I can sit behind my driving position with legroom to spare and more than enough headroom.

Boot space is good at 500 litres, which is 20 litres more than the luggage capacity of the IS 350.

Storage throughout the cabin is good with two cup holders in the rear centre fold-down armrest, two more up front and bottle holders in all doors. A large centre console storage bin and another big storage area in front of the shifter are great for keeping junk under control and your valuables covered.

Long, low and wide. These are prerequisite proportions for a traditional grand touring 2+2 coupe, and with them come traditional packaging compromises.

With a near 3.0-metre wheelbase, there’s tonnes of room for legs, shoulders and even heads if you’re willing to sit nice and low, though the lush ambience is more cosy than coastal because of the accompanying broad centre console.

The dual central screens look like an open tablet, and it’s perfectly sized and easy to use. Same goes for much of the controls, while the driving position is, thankfully, first class. Just like the fit and finish.

Beating Mitsubishi’s TR Magna to the punch by decades, there’s an analogue clock perched above the centre vent outlets, which is digitalised and contains performance telemetry as per Porsche’s equivalent.

Vision is a little limited by the fat pillars and upswept window line but the big screens help. Storage is okay, and access to the rear is only for the very young, very fit or very limber.

Two more seats out back provide snug comfort, but the GranTurismo really is all about the ones up front. Overall, the cabin design’s restrained modernity matches the exterior’s styling philosophy down to a tee.

Further back, the boot lid opens electrically because why not, revealing 310 litres of cargo space. The rear seat doesn’t fold, but there is a ski-hatch into the cabin for broomsticks and some such.

Speaking of flying high, let’s take a look at the other side of the GranTurismo.

Beauty like this does not come cheap. What Italian supercar does?

The Modena is the base grade, kicking off from an Australian luxury-tax addled $375,000, before on-road costs, while there’s also the top-of-the-line Trofeo, from $450,000.

This puts the GranTurismo smack-bang in the middle of several other high-end 2+2 sports coupes besides the 911 and Conti GT, such as the Aston Martin Vantage, BMW M8 Competition and Mercedes-AMG GT.

Clearly, privilege brings the luxury of variety.

Now, as you’d probably expect, the GranTurismo is a pretty lavishly presented and equipped proposition.

Yet it’s the sheer modernity of the Torinese icon that might catch you by surprise – until you learn there’s also a cutting-edge and completely electric Folgore version also coming to Australia sometime mid-next year.

There’s a sense of that thinking with a pair of sizeable digital display screens – one ahead of the driver and a 12.3-inch touchscreen to the centre, sat above a smaller, 8.8-inch climate control display like an open tablet.

You’ll also find sumptuous leather, a 360-degree camera view, a head-up display, a digital rear-view mirror, high-end premium audio with 14 speakers and an Android-based multimedia set-up offering Alexa assistance, ‘Hey, Maserati’ voice-control and even a Wi-Fi hotspot.

It’s the repurposing of the traditional analogue clock perched up on top of the dash as both an analogue-look timepiece and performance telemetry screen that best juxtaposes the classic with the contemporary.

That, and the long list of adaptive driver-assist safety systems, which will be spelled out in more detail in the safety section below, as well as the standard air suspension and adaptive dampers. All underline the GranTurismo’s security, luxury and comfort yang to its supercar-performance yin.

Still, regardless of how many more features or more performance the Maserati’s competitors may have over it, the GranTurismo possesses one luxury no other quite manages as naturally and that’s supermodel looks.

Inside the Q50 Red Sport's nose is a 3.0-litre twin-turbo V6 petrol engine and it is a beautiful thing. To me this car is piece of technologically sophisticated jewellery that cradles a precious gem that pumps out 298kW/475Nm.

But I have my concerns... you can read about those in the driving section.

Shifting gears is a seven-speed automatic which delivers drive to the rear wheels.

So, no more Ferrari-sourced V8, eh?

Yet, it’s not just a sexy body that Maserati has mastered, because this particular 2992cc 3.0L twin-turbo V6 is pretty-much exactly the same engine as you’ll find in the company’s MC20 supercar, give or take a bunch of outputs.

Called the Nettuno, it isn’t quite in the performance league of the GT’s mid-engined two-seater sibling, but with 365kW of power and 600Nm of torque in the Modena and 45kW/50Nm more in the Trofeo, it’s a spine-tingling symphony of speed and total jailbait… especially given the latter’s 320km/h maximum velocity.

That’s 18km/h quicker than the standard tune, and the Trofeo also shaves 0.4 seconds off the 0-100km/h sprint time at just 3.5s flat.

Either engine, though, feels terrifically quick and smooth and no doubt that’s aided by what must be one of the world’s greatest automatic transmissions in the eight-speed ZF unit. It sends drive to all four wheels.

Given the length, girth and opulence, a kerb weight of just 1795kg is outstanding, allowing a power-to-weight ratio of 203kW per tonne in the Modena and a knockout 228kW/tonne in the Trofeo.

To help keep all that in check, the GranTurismo also deploys double wishbones up front, a multi-link independent rear suspension set-up, along with the aforementioned air suspension – which is a nice nod to history as French carmaker Citroen used to own Maserati.

Anyway, the active suspension works in tandem with the four self-explanatory driving models fitted – 'Comfort', the default 'GT', 'Sport' and 'Corsa' (track).

Infiniti says the V6 petrol engine in the Q50 Red Sport should use 9.3L/100km if you're using it on a mix of highways, urban streets and country roads. We only had the Q60 Red Sport for 48 hours and after a couple of days of Sydney city commutes and a trip to the Royal National Park our trip computer was reporting 11.1L/100km.

You know, for a super coupe that can easily exceed 300km/h, the GranTurismo is pleasingly efficient, with a combined cycle average figure of 10.2L/100km.

Top that 70L tank with premium unleaded petrol, and you might even average over 680km between refills if you can restrain yourself from poking the bear under the bonnet.

How? Clean aero efficiency, along with that predominantly aluminium body that helps keep the weight down to under an impressive 1.8 tonnes.

Which all bodes really well for 2025’s Folgore EV version, which can also hit 100 in 2.7s on the way to 325km/h. Bring that on!

Perhaps the biggest complaint we had about the previous Q50 Red Sport, which launched in 2016, was that it felt as though the chassis wasn't up to the amount of grunt running through it, and those rear wheels struggled to transfer the oomph to the road without losing traction.

We experienced the same issue again in this new car. I was breaking traction, not just in 'Sport+' and 'Sport' modes, but in 'Standard' and 'Eco', too. That was happening without pushing it hard and with all electronic traction and stability aids on.

If I was 18 I'd declare to the world I'd found my dream car - something that always wants to 'light 'em up' given half a chance. But like that one mate who always gets into trouble on a night out it's only funny when you're young.

A truly great performance car is planted, balanced and able to deliver the grunt to the road effectively. The Nissan R35 GT-R is the perfect example – a brilliant piece of machinery, a weapon of a performance car and with a chassis matched perfectly to its engine.

And that could be the issue with Q50 Red Sport - that engine feels overpowered for the chassis, and wheel and tyre package.

We also felt the previous Q50 Red Sport's ride, with its constantly adapting 'Dynamic Digital Suspension', was overly busy. Infiniti says it has developed the suspension system further and it does feel as though the ride is more comfortable and composed.

Steering was another area that we weren't overly impressed with when we drove the previous car. Infiniti's 'Direct Adaptive Steering' (DAS) system is super sophisticated and was the first in the world not to have any mechanical connection between the steering wheel and the wheels – it's all electronic.

The new Q50 Red Sport uses the upgraded 'DAS 2' and while it feels better than before, it's only in Sport+ mode that it seems most natural and accurate.

Though it has been modified by what may be an almost unrecognisable amount by Maserati’s engineers, using Stellantis’ Gorgio architecture that first appeared in the magnetic Alfa Romeo Giulia of 2016 and then utterly seduced in the flagship Quadrifoglio version is a great place to start.

Now, we’ve only tested the all-new GranTurismo (GT from here on in) coupe around the fast and challenging Tailem Bend race track near Adelaide, so cannot speak of its behaviour on Australian public roads.

But what we experienced was an incredible and elevating sports car experience. And, yes, that's despite the loss of the magnetic Ferrari-based 4.7-litre V8.

Even with ‘just’ 365kW of power and 600Nm of torque, the base Modena twin-turbo V6 thunders off the line, its superb ZF eight-speed automatic transmission, surely the best of its type in the world, shifting with lightning speed through the ratios as it blitzed past 100, then 150, then 200km/h in mere seconds. Maserati says within 8.8s, in fact.

To help keep all that in check, the GranTurismo deploys double wishbones up front, a multi-link independent rear suspension set-up, along with the aforementioned air suspension – which is a nice nod to history as French carmaker Citroen used to own Maserati.

Anyway, the active suspension works in tandem with the four self-explanatory driving models fitted – 'Comfort', the default 'GT', 'Sport' and 'Corsa' (track).

We were too thrilled to notice whether the loss of the Maserati V8 grumble, because the exhaust howl was exciting enough, along with the sheer ease in which the GT accelerates.

And when we needed to suddenly brake reaching corners that seemed stupidly close until we realised they weren’t, we also were relieved at the Modena’s marvellously effective Brembo brake package.

Now, at under 1900kg, the GT is still a heavy car, but not for a five-by-two metre-long-and-wide 2+2 seater coupe.

Seriously, the cohesion and crispness of the steering, whether in Comfort or three-settings down in shockingly heavier Corsa mode, tingles the senses, seeming far lighter and more agile than the (albeit lithe) luxury coupe styling suggests.

Not Porsche 911 supernatural-alacrity, but beautifully quick and reactive nonetheless. It’s such a buzz.

There’s also a sense of isolation from the air suspension underneath, aided by the trick adaptive dampers doing their bit too to cushion the ride. The vital luxury part of the GT equation is omnipresent in the Maserati coupe.

And this was all just in the Modena. Another few laps in the Trofeo just sharpened the senses and speed and responses, supercharging the experience around Tailem Bend.

What all this left us is a longing for more time behind the wheel. Which hopefully will happen soon, but for now, this is far-and-away the best Maserati I have ever driven. If you can afford one, this is all great news.

Of course, back in the real world on everyday roads, there will surely be criticisms, but for now, around the circuit, the GranTurismo is something very special indeed.

It might shock to learn that supercars like this generally are not crash-tested by EuroNCAP or other such agencies, so there’s no rating.

But most of today’s advanced driver-assist tech is present and active in the GranTurismo along with a super-strong body, massive Brembo brakes and that trick air suspension to help keep everything grounded.

The 'Level 2' tech includes front and rear AEB, blind-spot warning, lane support systems with alerts and intervention, rear cross-traffic alert, driver attention alert and auto high beams. Front, side and rear cameras are also fitted.

Plus, there are six airbags (dual front, dual side and curtain for both rows), along with anti-lock brakes, brake assist, electronic brake-force distribution, electronic stability control, traction control and front/rear parking sensors.

Two ISOFIX restraints and child-seat anchorage points are integrated into the rear pair of seats.

The Q50 Red Sport is covered by Infiniti's four year/unlimited kilometre warranty with servicing recommended every 12 months or 15,000km.

Infiniti has a scheduled servicing program which will cost $1283 (in total) for three years.

Maserati offers a frankly disappointing three-year/unlimited kilometre warranty, which is on the stingier side of things.

Service intervals are also every 12 months or 10,000km.

There is no capped-price servicing, but Maserati offers a pre-paid maintenance program that covers all the inspections and components and consumable replacements.

As the pricing was not finalised at the time of publishing, best to check the company’s website for the latest details.
