BMW 320d vs Mazda CX-80

What's the difference?

Despite BMW's wholehearted embrace of the SUV its 3 Series is still a critically important model for the brand in Australia. And this new version certainly has the spec and tech to take the fight up to Merc's C-Class. And if you're in the happy position of making that choice, it's now a whole lot harder. For our money the 330i marks the sweet spot with extra performance, safety tech and standard features for only a fraction more than $3k over the 320d entry-point.

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.

At just over 4.7m nose-to-tail the new 3 Series has crept 76mm in overall length but that dimension is still more than 200mm shy of its next-size-up 5 Series sibling.

Changes to the exterior design are more evolutionary than revolutionary. You're never going to mistake this car for anything other than a BMW 3 Series.

But even if the face is familiar, aerodynamic efficiency is outstanding. BMW admits its claimed Cd of 0.23 was achieved with a base model running on 17-inch wheels (not offered here), but even if bigger rims knock a few fractions off that number it's still an amazing result for a conventional four door sedan.

Big contributors are a full width front spoiler, 'air curtains' managing flow around each corner of the nose, almost complete sealing of the largest areas underneath the car, and a functional rear diffuser section.

The signature kidney grille has grown and is delivered as a single piece, with active shutters incorporated to manage cooling air flow through to the engine. Twin adaptive LED headlights (standard on all models) feature a sharp notch on their lower edge, a big clue for new model spotters.

Broad, carefully managed surfaces characterise the bonnet and flanks of the car, with a distinct character line just above door handle height enhancing its confident stance.

The slightly smoked L-shaped LED tail-lights sit proud of the body, and 18-inch alloys are standard on the 320d, stepping up to 19s on the 330i.

The interior has been redesigned with revised controls and new materials, including slick 'aluminium teragon' finish on the console and dash in the M Sport.

As you can see in our interior images, it's been tidied up and simplified considerably, although it will still be instantly recognised by current BMW drivers.

Highlights are a 12.3-inch configurable digital 'Live Cockpit Professional' instrument display (lifted directly from the X5), a new 10.25-inch media touchscreen and a standard (larger) head-up display.

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.

A longer wheelbase (+41mm) has helped increase overall cabin space and rear room specifically.

There's plenty of storage provided with a large lidded box between the front seats as well as two large size cupholders in a recessed section in front of the gear shift (which can be closed off with a roll-top style cover).

The glove box is large and there are big bins in the doors with separate holders for full-size bottles.

Rear legroom is generous. At 183cm, sitting behind my own driving position, there was plenty of fresh air between knees and seatback, with lots of foot room to boot.

Headroom was more marginal with a straight back leading to a bonce/roof interface. But there are adjustable rear vents, twin cupholders in a fold-down centre armrest, and big bottle holders in the doors. Multiple USB ports (Type A and Type C) and a 12-volt power outlet are provided front and rear.

The boot space offers up a 480-litre luggage capacity with a 40/20/40 split-folding rear seat increasing cargo flexibility. Local towing capacity is yet to be confirmed, but indicative (European) ratings for both models are 750kg for an unbraked trailer and 1600kg braked.

Standard rubber is run-flat so there's no spare of any description.

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.

Mazda offers a choice of five CX-80 grades and for almost all of them, you get the option of a new mild hybrid petrol or diesel, or a plug-in hybrid powertrain.

The Touring G40e model on test for this review is second-from-the-bottom and has a petrol mild-hybrid powertrain. It is priced from $61,950 before on-road costs and the Artisan Red Metallic paintwork our test model has adds $995 to the price tag.

The Touring is more affordable than some of its rivals, including the Toyota Kluger GXL at $70,440 MSRP and Hyundai Santa Fe Elite at $62,500 MSRP. However, these two models are full hybrids and the Santa Fe has a slightly longer features list for only a little bit more money which makes it better value overall.

The great thing about Mazda is once you move up from the entry grade, you often benefit from a host of great standard features that would usually come as part of a package or cost extra with other brands. For example the Touring gets leather upholstery, heated and powered front seats and a wireless charging pad, which isn't too bad for a grade that sits towards the start of the range.

There are some solid practical features like the keyless entry and start, rain-sensing wipers, dusk-sensing headlights, powered tailgate, three-zone climate control, retractable sunblinds (second row) and 360-degree view camera system.

Tech feels well-rounded with a 10.25-inch multimedia system, six USB-C ports, two 12-volt sockets, a 220-volt/150W AC socket, satellite navigation and wireless/wired Apple CarPlay and Android Auto.

In terms of value within the CX-80 range, the Touring G40e is the pick of the litter.

The 320d is powered by a 2.0-litre four-cylinder twin-turbo-diesel, featuring common-rail direct-injection and variable inlet timing. It produces 140kW at 4000rpm and 400Nm between 1750-2500rpm.

The turbo's multi-stage design incorporates a small, high-pressure, fixed-vane turbocharger as well as a larger, low-pressure, variable-vane turbo to maximise response, performance and efficiency.

A 2.0-litre single turbo-petrol four-cylinder engine sits under the 330i's bonnet incorporating direct-injection, as well as variable valve and cam timing. Peak outputs are 190kW from 5000-6500rpm and 400Nm between 1550-4400rpm.

Mark the date because this is the first time the BMW 3 Series has been offered in Australia without a manual gearbox option. Both launch models send drive to the rear wheels via an eight-speed automatic (with wheel-mounted shift paddles) only.

 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.

Despite each car's performance potential claimed fuel economy for the combined (ADR 81/02 - urban, extra-urban) cycle is commendably low.

BMW says the 320d delivers excellent diesel fuel economy, consuming a miserly 4.5L/100km, emitting 119g/km of CO2 in the process, with the 330i's fuel consumption figure coming in at 6.4L/100km and 147g/km.

You'll need minimum 95 RON premium unleaded in the 330i, with both petrol and diesel requiring 59 litres to fill the tank to full capacity.

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.

First, the performance figures. BMW claims the 320d will accelerate from 0-100km/h in 6.8sec, which is agreeably quick, while the 330i knocks that down to 5.8sec, which is properly fast.

Both engines deliver the same 400Nm of maximum torque at low rpm; 1750-2500rpm for the 320d, and a broader 1550-4400rpm spread for the 330i. Mid-range acceleration is strong and satisfyingly linear in each, the 330i that bit more urgent at the top end.

The eight-speed auto is velvety smooth, with the wheel-mounted shift paddles on hand for rapid 'manual' changes. Engine noise is muted at low revs but nice and rorty under pressure.

A stated aim in the development of this 3 Series was "dynamic engagement", and the standard strut front, multi-link rear suspension has been tuned to reinforce the driving part of the brand's long-standing 'ultimate driving machine' promise.

The standard suspension includes tricky two-stage dampers front and rear, but with all cars at the local launch fitted with the optional active damper system we'll have to wait to report on its quality (or otherwise).

This car's centre-of-gravity is 10mm lower than the model it replaces, which may not sound like much, but in engineering terms, absolutely is. In concert with a perfect 50:50 front-to-rear weight distribution, and wider tracks front and rear, it helps deliver an overall planted feel and predictable cornering balance.

The electro-mechanically assisted steering is accurate and linear with good road feel, which is not always the case in recent Beamers.

The launch fleet was also rolling on 19-inch rims (standard on 330i, optional on 320d) shod with Bridgestone Turanza run-flat rubber (225/40f - 255/35r) and despite that type of tyre's reputation for harsh characteristics and a moderate level of road noise, ride comfort on the typically coarse rural roads we covered in the Victorian high country was impressive.

Braking on both models is by ventilated disc front and rear, and even in spirited cornering maintained their power and efficiency. The M Sport brake package fitted to the 330i dials things up with four-piston alloy calipers (sourced from Brembo) up front.

The standard sports steering wheel is fat and grippy, the sports front seats combine firm location with long-distance comfort and overall noise levels are low. Overall, this is a super-impressive touring car.

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.

At the time of this review the new Mazda CX-80 hasn’t been tested with ANCAP and is thus unrated but it has 10 airbags which is great for a big family SUV and includes side-chest airbags for the second row and curtain airbags that extend to the third row.

The Touring G40e model features a robust list of standard safety features including auto emergency braking (AEB), safe exit assist, front and rear cross-traffic alerts, blind-spot monitoring, driver attention alert and monitoring, forward collision warning, lane keeping aid/departure, front and rear parking sensors, a 360-degree camera system, traffic sign recognition, intelligent seatbelt warning and a tyre pressure monitoring system.

The adaptive cruise control is one of the most user-friendly I’ve sampled recently and other than a sensitive lane keeping aid, all systems follow that user-friendly vibe.

There are a total of five top-tether points and two ISOFIX child seat mounts. The width of the middle seat means you should be good to fit three child seats side by side if they're not too large.

BMW offers a three year/unlimited km warranty, which is drifting off the pace now with the majority of mainstream brands stepping up to five-year cover, with some at seven.

On the upside, bodywork is covered for 12 years, the paint for three, and 24-hour roadside assistance is complimentary for three years.

Servicing is condition based, so the car tells you when maintenance is required, and BMW offers a range of service packages in 'Basic' and 'Plus' grades up to 10 years/200,000km.

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.
