Infiniti Q50 vs Peugeot 508

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.

The Peugeot 508 Sportswagon GT PHEV proves wagons can be extremely stylish but looks aren’t everything and it is an expensive option compared to its luxury rivals. It earns its place with the premium interior but the safety could be improved on and the tech is more confusing than it needs to be. But this wagon offers an alternative for families who are sick of being in an SUV yet still need a little extra space. 

My son didn’t go nuts over this and complained about his view.

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.

The design of this wagon is what wins it the most points. It is a damn fine specimen with the sleek lines in the body panelling and the sexy rear that looks well-proportioned for its 4790mm length.

Dark, narrow windows, 18-inch alloy wheels and a minimalist-looking nose, with fang-like daytime-running lights, all enhance its sporty look.

The rear lights have Peugeot’s signature ‘claw’ design and there’s something suggestively fun about seeing a twin-exhaust on a wagon!

On the interior, the multimedia system takes centre stage and the dashboard looks quite sleek, despite all of the deep cutaways.

The steering wheel is in the compact style that Peugeot is known for but it makes the cockpit feel driver orientated.

The quilted Nappa leather trims and shiny piano-black accents (with the piano-key controls) make for a refined cabin space.

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.

The front row gets the most space and you’ll be able to get into a comfortable position even if you’re tall.

However, it is a low car with its 142mm ground clearance and there may be a few grunts as you get in and out (or is it just me?).

My seven-year old loves how easy it is to climb in, though he didn’t have the best view out of the windows because the sills sit high.

The footwell lip also sits quite high, which isn’t an issue until you can’t open your door very wide and then it’s clumsy in a tight parking space.

The electric front seats are very comfortable and the extendable under-thigh support helps to minimise leg fatigue on a longer journey.

Surprisingly, for my 168cm (5'6") height, I have to sit much further back than I ordinarily would to get a comfy driving position.

In the back, you have plenty of headroom but behind my driving position, the legroom could be better.

An adult would still find it fairly comfortable on a longer journey so long as they aren’t behind someone tall. The seats themselves are well-cushioned and you sit in, rather than on top of them.

Individual storage options are good for this class with a dual-opening middle console, glove box and a great utility cubby next to the transmission shifter.

There is also a shelf underneath the centre console that houses the wireless charging pad and two USB-A ports but it’s a tad awkward to use and even see the ports when you're seated.

The amenities are good in the rear but for a top-spec model it’s lacking the luxury items you might expect, like heated seats and climate control but you’ll enjoy map pockets, reading lights, two USB-A ports and directional air vents.

It also has a fold-down armrest with two shallow cupholders, that in a quick turn, might spill their cups!

The boot is a great size at 530L with all seats in use and you can bump it to 1780L with the rear seats folded.

You get a level loading space and a 60/40 split with a ski-port in the back seat, which opens up your storage options.

There is a tyre repair kit rather than a physical spare but the tailgate is powered, which I always like.  

The technology is a mixed bag. It looks sharp and the touchscreen multimedia system is responsive but isn’t as easy to use as others I’ve sampled.

It doesn’t have a lot of accessible information or customisations available but it is easy to connect to the wired Apple CarPlay. There is also wired Android Auto for those users and built-in satellite navigation. 

The 12.3-inch digital instrument panel is the prettiest piece of tech in the car and there is more customisation available to make it feel yours.

Considering its price point and top-model status, it's more obvious that you miss out on premium items like three-zone climate control, faster USB-C connections and a head-up display.

Keeping things simple, there are only two variants for the 508 Sportswagon and our test vehicle is the top GT plug-in hybrid model that will cost $82,915 before on road costs.

That’s a $1000 price hike from last year and sets it well above its rivals with the Audi A4 coming closest at $78,169 (MSRP).

Given its rivals are well known for their luxury, the 508 has a fair bit to live up to but its styling and use of premium materials, like the quilted Nappa-leather trims, help it earn its position within the ranks.

The interior gets some other lovely big-ticket items with the eight-way electric front seats and a two-way memory position function on the driver’s seat.

Both front seats feature a heat function, adjustable lumbar support and a fabulous massage function. The ‘Cat Paw’ option is particularly nice!

However, the back seat misses out on these ‘top-end’ creature comforts.

There is a sunroof optioned on our test vehicle which adds $2500 to the price tag but creates an airy cabin in what would ordinarily be a bat-cave-esque space with that black headliner.

Only one colour is included in the price and our ‘Pearl White’ costs an extra $1050.

Technology has been revitalised with a new 10-inch touchscreen multimedia system and a 12.3-inch digital instrument cluster.

Dual-zone climate control, push-button start, keyless entry and a powered tailgate all add some practicality to every day life, too.

Phone mirroring tech like wired Apple CarPlay and Android Auto are easy to connect to and there are a bunch of charging options available throughout the car, including a wireless charging pad up front.

All-in-all, though, the features list isn’t as long as the price point might suggest.

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.

The GT plug-in hybrid model has a 1.6-litre, four-cylinder turbo-petrol engine, as well as an electric motor that sits on the front axle. It has an eight-speed automatic transmission that produces smooth gear changing driving the front wheels.

The combined outputs are 165kW and 360Nm which means you have a good amount of power for this sized car but it’s not a performance wagon as its 0-100km/h sprint time is 8.3 seconds.

The lithium-ion battery has a small 11.8kWh capacity and will get from 0-100 per cent in three and a half hours on an 11kW system. On my standard house plug, it took closer to six and a half hours.

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.

Peugeot says you can travel up to 55km on pure electric function, however my morning (return) school run is 38.4km and the electric range was spent by the time I parked in my garage after starting on a full charge. 

Under optimal conditions, where you’re utilising both the engine and motor, the GT PHEV has an official fuel cycle consumption of 1.5L/100km.

After charging it three times, travelling 444km on a mix of open/urban roads and using 33 litres of fuel, my real-world usage came to 7.4L/100km.

You absolutely get the best economy when you regularly charge it but sometimes you just don’t get the time to!

You'll need 43 litres of premium 95 RON unleaded fuel to fill the tank which, using our real-world average consumption figure, translates to a driving range of around 580km.

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.

The 508 Sportswagon is an odd car to drive. Around the city, the steering makes it feel like you’re in a go-kart and you may over-correct until you get used to it. 

On the open-road, it feels like it gets into its groove but the power reserves feel a tad too shallow as the engine can complain with only a light load. 

The suspension is well padded and you won’t notice too many bumps but you do get a fair bit of wind and road feedback at higher speeds. 

Because of the narrow windows, I am surprised by how great the visibility is but you feel tiny when you sit next to a big SUV in traffic!

That said, it corners beautifully and taking this on a winding coastal road is super fun.

The brakes are very responsive, which is great in stop-start city traffic but can make it feel a little jerky while navigating a car park.

And on that note, because of the funky steering feel, it takes a moment to calibrate your senses with what the car is doing.

Once you get used to it, it’s simple to park but the quality of the 180-degree camera system is pretty rubbish for where this car sits in the market.

The 508 has most but not all of the safety features you expect to see in a family car.

The active bonnet is a great feature as it lifts up in a collision to help minimise pedestrian injuries. 

However, in the modern market and this being a top-spec model, I am surprised it's lacking a few safety features, namely rear cross-traffic alert.

Other standard safety equipment includes blind-spot monitoring, LED daytime running lights, forward collision warning, lane keeping aid, lane departure warning, intelligent seat belt reminders, front and rear parking sensors, a 180-degree view reversing camera, traffic sign recognition, a driver attention monitor, and adaptive cruise control with stop and go functionality.

The 508 has a maximum five-star ANCAP safety rating from testing done way back in 2018 and it only sports six airbags, which is low for a family vehicle.

The 508 has autonomous emergency braking with car, pedestrian and cyclist detection and is operational from 10.0– 80km/h (5.0 – 140km/h for car).

There are ISOFIX child seat mounts on the outboard rear seat positions and three top tethers in the second row but two child seats will fit best. Front passenger comfort may be compromised when a 0-4 rearward facing child seat is installed.

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.

On the 508 you’ll enjoy a five-year/unlimited km warranty and the battery is covered by an eight-year or up to 160,000km warranty, which is great.

You can pre-purchase either a three- or five-year servicing plan and the five-year plan costs a flat $2100 or an average of $420 per service which is very reasonable for this class. 

Servicing intervals are at every 12months or 20,000km, whichever occurs first.
