BMW 5 Series vs Mazda CX-3

What's the difference?

There’s no getting around the i5 being a rather expensive offering. More than $150,000 to get into an electric sedan that’s not much faster than a hot hatch is a big ask, but there’s plenty to enjoy about the 5 Series.

Things like its heated leather seats shouldn’t be the reason you’re willing to spend so much on a sedan when a $50,000 hybrid SUV will score you the same, instead it’s the fact the 5 Series is a delight to drive and hasn’t lost the feeling of prestige the badge has earned over the last half a century.

In terms of value - if speed isn’t your focus and you’re less of a gadget-type-operator when looking at cars like this - the 520i has the style and comfort you’d need and at $100K less than the M60.

And in terms of large electric sedans, the i5 eDrive40 is cheaper than a Porsche Taycan (by a little) or an Audi e-Tron (by a lot). The Genesis G80 Electrified is the closest cheaper rival, by about $10K, or the less powerful Mercedes EQE is similarly priced at $154,900.

Essentially, if you’re looking at a 5 Series, it might be worth considering if you really need it to be electric, but if so, there aren’t many alternatives in its category for the price.

‘You get what you pay for’ comes to mind with the CX-3, which is interesting given it’s neither the newest nor most feature-packed SUV in its class.

The ageing light SUV does however offer one of the best-put-together experiences in a car of this size and its engine is powerful for the class. Build quality feels well above par and there aren’t any annoying inclusions that are becoming more common in new cars.

There aren’t many downsides unless you were hoping for a big screen and the ability to play around with software functions, but at this end of the new car spectrum, a car that drives this well and remains stylish a decade on should be applauded.

Put aside its relative (but forgivable) lack of efficiency and somewhat smaller boot than rivals, and the CX-3 nails everything it needs to.

If you’ve watched other members of the BMW family go into a new generation within the last few years - the 3, 4 and 7 Series particularly, you won’t be too surprised by what you see here. Especially with the latter, having seen the petrol variants look roughly the same as the electric ones.

BMW specifically made the petrol 520i and the i5 variants look similar for egalitarian purposes - to not disenfranchise 520i buyers who are still spending a fair chunk of cash but might not be ready to go EV.

That means all three variants score a mix of new and old. The kidney grille remains and isn’t as large as on the M3 or 4 Series, while the bonnet line following it and the ‘character line’ down the car’s side also remain. And yes, the Hoffmeister kink where the C-pillar meets the passenger window’s lower corner is still there.

On that C-pillar though is a ‘5’ stamped into the bodywork, new to this generation, while the front grille as mentioned has a glowing light surround - the brand’s ‘Iconic Glow’ already seen on the 7 Series.

Overall, thanks to being slightly larger in every dimension, the new 5 is starting to look bigger than a 7 Series from a little while ago. And that’s because it is - its body is overall longer than an E65 7 Series from the mid-2000s.

It’s 5060mm long 1900mm wide, 1515mm tall (97mm longer, 32mm wider, and 36mm taller). Its wheelbase is 20mm longer too at 2995mm. 

For one, there’s the way it looks inside and out.

The Mazda CX-3 hasn’t remained the most popular car in its segment on price, so the fact its styling continues to age gracefully in the design-focused light SUV segment (aimed at young or first-new car buyers) must have something to do with it.

While it’s been lightly updated a couple of times since 2014, the CX-3 is still in its first generation and has stood the test of time.

Looking like a jacked-up Mazda2, the CX-3 brings some traditional aesthetic to a category peppered with more divisive and daring (but admittedly admirable) designs like the Hyundai Venue, Suzuki Ignis (RIP) or the cute but prohibitively expensive Jeep Avenger.

Some elements of the CX-3, like the chrome trim around the grille or the black plastic cladding along the bottom of the body and around the wheel arches, seemed in the past like they had the potential to age poorly, but Mazda’s design language has only slowly changed since 2015, and the CX-3 still looks at-home in the brand’s line-up.

It’s not the most adventurous - even inside its layout is quite basic - but it does give off a premium vibe and the fact it plays things a little bit safe means the CX-3’s broad appeal is undeniable.

A longer wheelbase means more space inside, where the 5 Series also still looks fairly familiar to those who have spent any significant time in a recent model BMW.

BMW has historically been pretty bang-on with ergonomics, and the new-gen 5 does a good job of sticking to that. Comfortable sports seats and quality feel for the materials on touch points mean the 5 Series feels nice to be in, and relatively restrained interior design for a somewhat luxurious car means it looks nice too.

It’s let down only by a couple of things - its multimedia screen and Operating System 8.5 is a little less simple to use now, and requires more touching the screen than previous iDrive systems, rendering the scroll wheel less useful.

The BMW Interaction Bar too is a little tricky to see controls on, as well as lacking physical feedback for using controls. Vent flow controls are digital sliders on the Bar, while vent direction is controlled by an unusual ‘joystick’ style control nearby.

The rear seat is plenty spacious, as you’d expect from a large sedan, with climate controls and ports for charging devices in the rear.

The Mazda CX-3 isn’t the most spacious light SUV on the inside, but from either of the front seats it’s clear a lot of thought has gone into the best way to make the cabin work.

For example, precious space hasn’t been wasted by two dedicated cupholders, instead there’s a cupholder in the central storage compartment that’s relatively easy to reach into.

Like its design and some of its features, the CX-3’s layout can’t hide its age - there are still big physical controls for the climate settings, the speedometer is a physical dial and the gear selector is a very traditional style.

Mazda’s soon-to-be-gone media control wheel persists in the CX-3, which is by no means a bad thing. It falls nicely to hand, as with many of the controls in the CX-3. Its seating position isn’t too high and the positions you’re able to get the seat and steering wheel into should accommodate most humans.

Behind the front seats it’s a little more spartan. Space is at a premium, with my 178cm frame fitting in the back seat just enough that I had a fair bit of headroom, but my knees were able to brush the seat in front, set to my own driving position.

There are no ports for charging or vents in the second row, but the fold-down armrest has a clever fold-away cupholder. The window shoulder is a little high for young kids to properly see out, but there’s enough light that it doesn’t feel cramped.

The boot is similarly diminutive, a 264-litre space becoming 1174L with the second row folded down. Compare it with the Hyundai Venue and its 355-litre boot, or the Toyota Yaris Cross and its 390 litres, and the CX-3’s simple, well-constructed interior starts to lose points.

Upon updating the Mazda CX-3, the Evolve variant is now a $32,100 ask before on-road costs, which is $900 more than before. It’s a little step up from the $30,370 entry price of the Pure, but falls well short of the top-spec Akari’s $38,890 sticker price.

The CX-3 range now comes with updated autonomous emergency braking and adaptive cruise control, with the Evolve specifically scoring new fog lights and keyless entry.

The Evolve also comes with black machined 18-inch alloy wheels, synthetic leather interior trim and front parking sensors.

This is all on top of the CX-3’s standard kit which includes a leather-wrapped gear shift knob, handbrake handle and steering wheel, keyless start, an 8.0-inch multimedia display, wireless Apple CarPlay and wired Android Auto plus LED headlights, daytime running lights and tail-lights.

For its segment, the CX-3 isn’t cheap. The Evolve grade is more expensive than pretty much the entire line-ups of rivals like the Kia Stonic or Hyundai Venue, and its price somewhat lines up with the newer, hybrid-powered Toyota Yaris Cross.

But there’s more to the CX-3 than just a list of features.

Despite BMW calling it ‘electrified’, the base 520i is only a mild hybrid so most wouldn’t realise unless they were told.

Its turbocharged 2.0-litre four cylinder puts out a modest 153kW and 330Nm, with power and torque sent to the rear wheels via an eight-speed automatic transmission.

BMW claims it’ll knock over the 0-100km/h sprint in 7.5 seconds, a few seconds too slow to blow anyone’s socks off.

The mid-spec eDrive40 has a little more kick to it, its rear-mounted electric motor capable of 250kW/430Nm and able to cut that time to 6.0 seconds.

It’s fitted with an 84kWh battery to draw its power from, the same as the 442kW/820Nm M60 with its all-wheel drive dual-motor setup.

The M-tuned i5 can hit 100km/h in a claimed 3.8 seconds. Bye bye socks, perhaps.

The Mazda CX-3 is still powered by a 2.0-litre, naturally aspirated, four-cylinder petrol engine, as has been the case for years. Its outputs remain at 110kW/195Nm.

It drives the front wheels only, via a six-speed automatic transmission.

BMW claims the petrol 520i sips 6.7 litres per 100km from its 60-litre fuel tank, though we were unable to independently test any of the claimed figures on the launch day.

The base car has a theoretical range of 896km if it was possible to achieve the claimed fuel consumption figure for the duration of the whole tank - but it isn’t and realistically you could knock about 20-30 per cent off that, depending on how enthusiastically you drive.

In the i5 variants, the same 84kWh battery provides slightly different ranges due to the eDrive40 using 16.56kWh per 100km, and the M60 using 18kWh.

The eDrive40 has a claimed 550km maximum range, while the M60 has a 506km figure thanks to its extra motor and weight.

Mazda claims the CX-3 sips 6.3 litres of fuel per 100km, minimum 91 RON petrol, though on test the small SUV returned an 8.1L/100km figure under a mix of urban, highway and some dynamic driving.

With its 48-litre fuel tank, that means you’re realistically likely to get about 550km to a tank, though theoretically given Mazda’s efficiency claim a 760km trip on a single tank would be possible - if you could recreate the test lab conditions.

For some cars, the list of features is what really separates the variants, but that’s not the case for the 5 Series. As is a bit of a BMW tradition, the drivetrains dictate the different trim levels and prices, and there are three fairly distinct flavours of 5 Series.

Starting at ground level, the 520i might at first seem like a bit of boring vanilla. Except it’s actually quite smooth and light vanilla.

There’s not a lot to write about when it comes to its drivetrain, but the lightness of its engine and petrol tank combo when compared to EV batteries and motors is refreshing, and makes for a quite dynamic rear-drive sedan.

Its 153kW and 330Nm is delivered smoothly enough with the mild hybrid assistance doing a little in helping responsiveness, but without intervening in the gearshifts it doesn’t feel particularly keen.

It lacks the ride comfort of the i5’s adaptive suspension, but it’s able to be driven in a spirited manner that belies its size and even, to some extent its 1725kg kerb weight. Chocolate sprinkles on the vanilla, if you like.

It’s not fast, but it feels nimble compared to its electric siblings and can carry a fair bit more speed through corners, after which there’s room to notice its rear-drive characteristics.

It’s especially noticeable after getting out of the 2130kg eDrive40, though the extra power from its 250kW/430Nm motor makes for some more spirited acceleration and a little more excitement when exiting a corner, especially if you’re aiming to double-check if it really is rear-wheel drive. There’s a little more than choc-topped vanilla going on here.

The steering is, like in the 520i, direct and responsive, though in most cases is probably best set to ‘comfort’ rather than ‘sport’ in its settings. 

The eDrive40 is rather comfortable and capable when barrelling through twisty backroads, and doesn’t feel out of hand for a five-metre-long sedan. It holds its weight well, and telegraphs when you might be approaching the limit quite sensibly.

When considering that, then, it’s impressive how brutally capable the 2305kg M60 is.

Here, we’re looking at a double-choc fudge with extra choc, and maybe some cookie dough in there for good measure. There’s a lot to like, but boy is it heavy.

It’s 580kg (or exactly half a Peugeot 208 GTi) heavier than the 520i, but it feels quick on its feet and its anti-roll seems to do a lot in terms of dynamics, the limiting factor really seems to be its tyres (which can and will squeal quite quickly to let you know when approaching said limit).

While you’ll need to take caution with how much speed you approach a corner with, you’re not going to lack acceleration on the other side, its all-wheel drive being less ‘fun’ but more efficient at getting you away from the bend than in the rear-drive eDrive40.

That adaptive suspension does also translate to a comfortable ride on relatively rough roads - only particularly bad bumps will reveal how much weight and pressure is being placed on each corner of the big sedan.

The light SUV category is an interesting one, as it feels somewhat like a gateway to bigger SUVs for those who get a taste of the higher seating position. But in city and urban areas, a light SUV should be as much car as someone needs - unless they have two kids or a bunch of equipment to get around with.

This comes down to the fact cars like the CX-3 are more efficient and easier to manoeuvre than their larger counterparts. And as light SUVs go, the CX-3 feels solid, confidence inspiring and more capable when outside its inner-city comfort zone.

Its naturally aspirated engine is big for the class. Even if it doesn’t feel the punchiest off the line it offers plenty of flexibility at higher speeds and makes overtaking on the highway feel less daunting than it would otherwise be in a car this small.

Its steering is light, which is an advantage in everyday driving, but has enough feedback that more dynamic driving is still engaging. It’s not sportscar-sharp, but you wouldn’t want it to be.

While its age would suggest the CX-3 should feel unrefined compared to newer small cars and light SUVs because of what lies underneath, Mazda’s work on the little SUV over the years has resulted in a car that feels mature and capable.

The suspension isn’t perfect, but it manages low-to medium speeds elegantly and does a decent job of maintaining stability at high speeds. It feels better than you’d expect from a car this size on the highway.

The 1294kg kerb weight and small-enough 18-inch wheels mean there’s not too much weight to manage, and there’s enough cushion in the tyres that harsh bumps don’t come crashing into the cabin.

While the CX-3 feels refined for its class, don’t expect a dead-quiet ride, as some road and wind noise make their way in above 80km/h. Then there’s the fact its engine and transmission will sometimes need to get a bit raucous when accelerating quickly. Aside from this, the CX-3 around town and in suburban areas feels nice and calm.

The Mazda CX-3 is technically unrated by ANCAP, though only because its original maximum five-star rating expired after seven years. While this means it easily passes many of ANCAP’s main criteria for safety (and strict Australian Design Rules - ADRs - to be able to be sold here), the CX-3 is missing some recent, more complex safety features.

Not everything is standard across the line-up, either. The Evolve misses out on adaptive headlights, a surround-view parking camera and traffic sign recognition. The base Pure variant also misses out on a front parking sensor.

Fortunately, there are plenty of other key features like seven airbags, dual-front and front-side plus curtain airbags spanning the sides. The CX-3 also has ABS and emergency braking with forward pedestrian detection and rear cross-traffic alert.

There’s lane departure warning, forward obstruction warning, blind-spot monitoring and a driver attention alert for those times you might miss something or - hopefully not often - are distracted.

All these systems are programmed well to minimise interference while driving, making the CX-3 refreshingly trusting of the driver to actually do the job of driving.

BMW has a fairly industry-standard five-year/unlimited kilometre warranty on its new cars, while its electric car batteries are covered by an eight year/160,000km warranty.

For servicing, BMW offers numerous discounted packs and deals based on your preferences and desire to pay upfront.

For the 5 Series, a five-year/80,000km basic service package is $2400, though the i5 will have different needs and lower servicing costs not yet listed by the brand.

Mazda offers a five-year, unlimited kilometre warranty, which is behind the curve for a mainstream brand these days. Rival brands like Kia and Hyundai offer seven years, for example, with some offering up to 10.

Servicing is undertaken every 12 months or 15,000km, whichever comes first, with servicing costing between $353 and $633 per visit. Total cost over the first seven years currently sits at $3233, averaging $462 a service, which is pricey considering the relatively simple mechanicals under the CX-3.

Mazda says there are more than 150 certified service dealerships across the country, with a tool to find the most convenient one for you. Given the CX-3’s advanced age, chances are there won’t be too many mechanical issues that haven’t been worked out in the last decade.
