Infiniti Q50 vs Mazda CX-5

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 Mazda CX-5 Akera G35 offers small families a great host of premium features, as well as solid power and handling – all in an attractive package. But the emphasis here is on ‘small’ families because it’s on the compact side for a mid-sized SUV and its rivals offer more back seat space.

Its ongoing costs are reasonable and I enjoy driving it, so it gets a 7.6/10 from me.

My son calls out the back seat as a bit squishy but he otherwise likes it. He gives it a 7.0/10

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 Mazda CX-5 hasn’t seen much change to the exterior other than a more horizontally-styled grille. It’s a medium SUV with a handsome kerb-side presence thanks to its full-suite of LED lights and 19-inch alloy wheels. It’s an inoffensive design that should appeal to a wide audience.

The interior looks premium with the brown Nappa leather upholstery and black leather trims. The plethora of soft-touchpoints throughout reinforces that the Akera is the top model.

There's one thing I really like about Mazda and that's how it manages to balance the traditional with the new. The cabin is a seamless blend of the two elements.

The instrument panel features a 7.0-inch digital display but still has analogue dials. There's a 10.25-inch multimedia system on the dash but still a bunch of control buttons and dials to press. The gear shifter is coupled with an electric brake, the sunroof is coupled with a manual blind. You get it.

This duology between high-end tech and traditional elements makes the interior feel up to date but very accessible.

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.

Despite sitting in the medium-SUV segment, the CX-5 is on the compact side for cabin space and front passengers benefit the most in terms of leg- and headroom.

Back rowers get a decent amount of headroom but legroom is squishy and my legs press into the back of the drivers seat when its in my driving position, and I'm only 168cm tall!

My seven-year old complained about his space and asked Dad to slide forward for more room, which is something to consider if you have gangly teenagers.

The seat comfort sits on the firmer side for both rows and the electric front seats are narrower and shorter than I like for long journeys but for the A to B trips, they’re comfy enough.

Only the driver’s seat gets powered lumbar support but they both have heat and ventilation functions.

Individual storage is average for this class with a smallish glove box and middle console that has a removable shelf. A deep utility tray, which houses the wireless charging pad and a 12-volt port, sits in front of the gearshift and there are two cupholders in the centre console.

Each door has a shallow storage bin and the front doors also get a skinny drink bottle holder.

For individual storage in the rear, you get map pockets on the rear of the front seats and two cupholders in a fold-down armrest.

The armrest also houses two USB-A ports and the heat function buttons for the outboard seats and it's because of this positioning and the narrower width of the seat, that the back row feels more suited to two, rather than three passengers.

The technology on the whole is easy enough to use but the rotary dial operation of the multimedia system is a bit annoying to access while on the go.

The wireless Apple CarPlay and Android Auto is a great feature and means one less cable to worry about but the built-in satellite navigation with 10-year map updates is a highlight. The head-up display pulls through the nav directions, too, which is always handy.

You also get two USB-C ports and another 12-volt outlet up front, so everyone should be sorted for charging.

The boot features a powered tailgate which is a handy family feature and a temporary spare tyre is located underneath the level floor.

You get 438L of storage capacity with the second row seat upright, which is plenty for my errands and grocery shop. That jumps up to 1340L (VDA) when the rear seats are folded. 

The cargo cover attaches to the lid, meaning it stays out of the way when you're loading stuff into the boot.

There are five grades for the CX-5. The top two grades, the GT SP and Akera, have a choice between a 2.5-litre petrol or turbo-petrol engine.

On test here is the flagship Akera grade with the 2.5L turbo-petrol engine. Before on-road costs, it is priced at $55,000. That positions it towards the top-end of its competitors with the Kia Sportage GT-Line AWD coming in at $49,920 (MSRP) and the Toyota RAV4 sliding in just under at $54,410 (MSRP). However, the new Honda CR-V is more expensive by $2.0K.

The Akera is well-equipped with premium features like a sunroof, heated and ventilated front seats, heated rear outboard seats, a heated steering wheel and brown Nappa leather upholstery.

The technology is well-rounded with a 10-speaker Bose sound system, wireless Apple CarPlay and Android Auto and a 10.25-inch multimedia system with built-in satellite navigation (including map updates for 10 years).

There are some good practical features, too, like a powered tailgate, keyless entry and start as well as powered lumbar support on the drivers' seat.

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 Akera is an all-wheel drive with a six-speed auto transmission and our test model has the 2.5-litre four-cylinder turbo-petrol engine that produces a maximum power output of 170kW and 420Nm of torque. The turbo ensures it never feels sluggish, even when you’re hitting hills.

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.

The compromise for getting extra power from the turbo is fuel efficiency takes a hit.

The official combined fuel cycle figure is 8.2L/100km but my real-world usage came out at 10L/100km. That’s after mostly open-road driving this week, too, so it’s a bit thirstier than I was expecting.

Based on the combined cycle number and the 58L fuel tank, expect a driving range of around 784km – which is still great for the odd road trip.

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 Akera turbo-petrol delivers a decent well of power to dip into and it feels peppy in most situations. Even when you’re overtaking or getting up to speed you don’t feel like you’re nearing the bottom of the power barrel.  

Steering is responsive and the car is agile when you tackle narrow car parks or streets. However, you still get some roll in corners which my passengers felt more than I did.

The cabin is quiet, even at higher speeds and the suspension is firm enough that you feel the bumps but you’re not jostled about. The ride comfort is still good.

I’ve said it before but I love parking medium SUVs because their size is so forgiving in a car park! The Akera is no different and it’s especially easy thanks to the ultra-clear 360-degree view camera system. You also get front and rear parking sensors to help out when needed. 

The Akera has a bunch of safety features that are always great to have on a family SUV and a standout is the 360-degree camera system. It’s super clear and well-positioned on the dashboard for easy viewing.

Standard safety items on the Akera include LED daytime running lights, blind-spot monitoring, rear cross-traffic alert, lane departure alert, lane keeping aid, a head-up display, adaptive cruise control, a driver fatigue monitor, AEB, forward collision warning and traffic sign recognition.

The previously awarded five-star ANCAP safety rating for this model has just expired and models built from January 2024 onwards are thus unrated. The CX-5 features six airbags, which is a little low for a family car but I like how many safety features this has overall.

There are ISOFIX child seat mounts on the rear outboard seat positions and three top-tethers but two seats will fit best. Front occupant comfort is 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.

The CX-5 comes with a five-year/unlimited km warranty, which is average cover for the class but some of its rivals offer longer terms.

There is a five-year, or up to 75,000km capped-price servicing program and services average $423 per workshop visit, which is competitive.

Servicing intervals are reasonable at every 12 months or 15,000km, whichever occurs first.
