Mazda CX-80 vs Audi RS5

What's the difference?

The Mazda CX-80 Touring G40e will do everything you ask of it and outside of pricey ongoing costs, there’s not much to annoy. It’s too large for my small family of three and if it’s kid stowage that you’re looking for, a people mover might offer better practicality and comfort than what this does. Would it be a model that you jump through hoops to get? Maybe not, but it still has a place as family hauler and is easy to drive.

Good looking, good to drive, and good to simply sit in, the Audi RS5 range ticks plenty of premium boxes. Whether you can live with the practicality pitfalls of the Coupe is up to you, but if you can't, might I suggest taking a wander over to our RS4 Avant review?

I've said it before but Mazda SUVs all look like scaled versions of each other to me and the CX-80 looks ridiculously similar to every other larger SUV model in the Mazda stable with the long pronounced nose that features sharp LED lighting and its general robust size.

The rear is where it differs with the proportions becoming a little bulbous but it’s practically shaped and overall is a nice-looking family SUV at the kerb side.

Head inside and the interior is pleasant with its high-quality trims and heavy-handed styling that matches the exterior dimensions with big panelling and air-vents up front to balance out the long width of this dashboard.

However, the whole car tends to lack personality for a model that’s a part of Mazda’s ‘premium SUV’ range. It's nice but doesn't add anything new.

I defy anyone to describe the RS5, and especially the Coupe, as anything but stunning. Seriously, the near perfect proportions and swept-back styling make it look fast even when it's parked. 

Up front, there's a new-look black-mesh grille that's been given a 3D effect, like it juts out over the road in front it, while the thing headlights have been carved back into the body work like they're been windswept under hard acceleration.

The 20-inch darkened alloys fill the arches, too, with a sharp body crease that runs from the front headlight all the way back to the bulging shoulder lines above the rear tyres accentuating the curves.

Inside, the RS5 is a sea of black Nappa leather and sporty touches, and we particularly like the chunky, flat-bottomed steering wheel, which both looks - and feels - great.

Seven-seat SUVs tend to really be a 5+2 combo, where the rear two seats are for kid- or emergency-use only. You'll be pleased to find that all passengers enjoy a decent amount of space in each row in the CX-80. The third row is still a little cosy for an adult but my 6ft2 brother managed to get back there without too many grumbles. However, we all giggled as he sort of fell in due to the lack of handholds (sorry, Mack).

Otherwise, the 170mm ground clearance and wide door apertures make it an easy SUV to get in and out of. The doors are heavy and sometimes miss their 'hold' position if you open them too quickly, making them swing back. My eight-year-old got whacked a few times because of it!

Amenities and storage are best in the first and second rows with front occupants enjoying those heated seats, two USB-C ports, a 12-volt socket and wireless charging pad. You also get dual-zone climate control, and powered seats with adjustable lumbar support. The seats are well-padded but fairly narrow and short in the base, making it easy to fatigue on longer journeys.

Storage includes a large glovebox that can hold a manual and a fair bit more, a shallow but handy middle console because of its dual-opening lid and a total of four drink holders. There's a sunglasses holder but not much else for smaller loose items.

In the second row you get two map pockets, a small storage bin in each door and a total of six drink holders. There's also individual reading lights, two USB-C ports, climate control, directional air vents, a fold-down armrest and retractable sunblinds (always a winning feature in my house).

The third row gets four drink holders, two USB-C ports and two directional air vents.

Feedback from my passengers (kids and adults alike) hasn't been great for the air-conditioning system with all complaining how long it took for the rear two rows to cool down. The low and awkward positioning of the air vents also prevents direct air flow to passengers. The third row is impacted by this as the passenger's legs cover them.

The rest of the technology is solid with the multimedia system offering a rotary dial operation. The system hasn't seen any recent updates, so if you're familiar with the Mazda system, you'll get along just fine.

The built-in satellite navigation is simple enough to use and the wireless Apple CarPlay is easy to connect to. There's also wireless Android Auto. Call connections remained consistent but feedback was that there seemed to be a fair bit of background noise on my end during calls.

Rounding out the interior is the boot space which offers a level loading space, retractable cargo blind and underfloor storage which houses the tyre repair kit. There's also a 12-volt socket and 220-volt/150W AC socket housed on a side panel.

With all three rows up, you get 258L of capacity and that figure jumps up to 566L when the third row is stowed. The CX-8 offered more boot space but the CX-80 is still respectable for the annual family road trip. Plus you get a powered tailgate function in the Touring model, which is always appreciated.

We only tested the Coupe, and I can tell you that the practicality perks on offer largely depend on where you're sitting.

Up front, you're spoiled for room in the two-door Coupe, with the two spacious seats separated by a sizeable centre console that's also home to two cupholders and a variety of cubbies, with extra bottle storage in each of the front doors. 

The back seat, though, is a little, or a lot, tighter, with come acrobatics required to even climb into it, given the Coupe only has two doors. The Sportback offers two more doors, which will surely make the process a little easier. 

The Coupe measures 4723mm in length, 1866mm in width and 1372mm in height, and will deliver a decent 410 litres in luggage space in the boot. The Sportback measures in at 4783mm, 1866mm and 1399mm, and boosts your luggage space to 465 litres.

Either vehicle has your tech needs sorted, with an abundance of USB and power outlets serving both front and backseat riders.

It's available as a Coupe or a Sportback, but either way, the RS5 commands a $150,900 asking price. And that's not chump change, but Audi's performance model does come with a lot of bang for those bucks.

We'll get to the engine and safety stuff in a moment, but in terms of fruit, you'll find 20-inch alloys outside, as well sportier RS body styling, sport brakes, Matrix LED headlights, keyless entry and push-button start and heated mirrors, a sunroof and privacy glass. Inside, there's Nappa leather seats (heated in the front), illuminated door sills, stainless steel pedals and ambient interior lighting.

The tech stuff is handled by a new 10.1-inch central touchscreen that gets both Apple CarPlay and Android Auto, as well as Audi's Virtual Cockpit, which replaces the dials in the driver's binnacle with a digital screen. There's also wireless phone charging, and a killer 19-speaker Bang and Olufsen sound system.

 The CX-80 Touring G40e model has an eight-speed auto transmission and all-wheel drive via a 3.3L turbo-petrol in-line six-cylinder engine coupled with a 48-volt mild hybrid system that produces up to 209kW of power and 450Nm of torque.

It’s not ridiculously powerful but pick up is great and there's more than enough to move the CX-80's big body around and support a 2500kg braked towing capacity.

Its a terrific engine, this - a twin-turbo 2.9-litre six-cylinder TFSI that will deliver 331kW at 5700rpm and 600Nm at 1900rpm, sending it thundering to all four wheels (because quattro) via an eight-speed tiptronic automatic.

That's enough, says Audi, to deliver a 0-100km/h sprint time of 3.9 seconds in the Coupe and the Sportback. Which is very, very quick.

The Touring G40e model has a 74-litre fuel tank and an official combined fuel cycle usage of 8.4L/100km, which gives you a theoretical driving range of up to 880km.

The mild-hybrid system works well enough that I didn’t hit double digits for fuel usage despite not being shy on using the power while hauling cargo and people on a mix of open road and urban trips.

My real-world use popped out at 9.3L/100km and while the diesel variant has much more efficient outputs and range, this result is pretty good for such a massive SUV.

The RS5 Coupe will sip a claimed 9.4L/100km on the combined cycle, and emit a claimed 208g/km of Co2. It's fitted with a 58-litre fuel tank. 

The RS5 Coupe will the same 9.4L/100km, but emit 209g/km of Co2.

The Touring G40e model is pleasant, if a little boring, to bum around in. Boring may be too strong a word but there's not much that gets you excited about the driving experience. The Touring performs and has decent power through most situations but it lacks a certain edge. It's not particularly sporty, nor does it sound mean when you put your foot down.

It's nice and does what you expect it to do.

The ride comfort is good with cushioned suspension with enough road feedback but people in the back will jostle a bit over the worst of the bumps.

Road noise can creep in at higher speeds and third rowers will struggle to be a part of the conversation but overall the cabin is refined for longer journeys.  

Visibility is mostly good because of the big windows but the wider pillars mean I check my blind spots very carefully, as the side mirrors seem a tad too small for the bulk of the car.

The CX-80 has a small turning circle of 11.6m and most of the time it never feels like it lumbers, but when you’re manoeuvring it in a tight car park the steering can feel heavy and a three-point turn starts to feel clumsy.

A saving grace is the excellent quality of the 360-degree camera system which takes out some of the puff from parking it. The CX-80 fills a space and it’s one you'd be careful to park so you don't get crowded.

With our time behind the wheel limited to the RS5 Coupe, we can only really report on how the two-door feels on the road, but given the prodigious power on offer, it's unlikely the addition of two doors is going to make the Sportback any slower. 

In short, the RS5 is thunderously fast, collecting speed with utter nonchalance thanks to this thick and endless-feeling supply of power unleashed whenever you plant your right foot.

It makes even the most ham-fisted attempts at cornering feel fast as lightning, with the power flow able to make up for every slow entry and exit by simply piling on pace between bends. 

But that's what you expect from an RS model, right? So perhaps more impressive is the RS5's ability to transform back into a relatively sedate urban cruiser when the red mist subsides. The suspension is firm, especially over rough road surfaces, and you do need to be a little careful with the accelerator to avoid that lurching feeling at every green light, but driven calmly, it doubles as a everyday car quite nicely.

Like in the RS4, we did find the gearbox felt a little quick to change at pace, shifting up or down at strange moments on the way into or out of corners, but you can reclaim control via the paddle shifters.

The safety story begins with six (Coupe) or eight (Sportback), and the usual suite of braking and traction aids, but then climbs into the tech-savvy stuff from there.

You get a 360-degree camera, adaptive cruise with stop and go, active lane assist, front and rear parking sensors, AEB with pedestrian detection, rear cross-traffic alert, an exit warning system, blind-spot monitoring and turn assist, which monitors oncoming traffic when making a turn.

It's a lot of gear, and it all contributes to Audi's five-star ANCAP safety rating, awarded in 2017 to the A5 range.

The CX-80 is let down a bit by its ongoing costs.

Mazda offers the CX-80 with a five-year/unlimited kilometre warranty which is fairly standard. A number of its rivals are offered with up to seven-year terms these days.

You get a five-year servicing program with services averaging $694, which makes it on the more expensive side, but servicing intervals are reasonable at every 12 months or 15,000km, whichever occurs first.

Audi vehicles are covered by a three-year, unlimited-kilometre warranty, which is feeling more than a little underdone when compared to some competitors.

Services are due every 12 months or 15,000kms, and Audi allows you to pre-pay your service costs for the first five years, at a cost of $3,050.
