BMW X3 vs Mazda CX-5

What's the difference?

If a BMW X3 is for you, then we have no quarrels with that. It’s a better all-round vehicle than the one it replaces and represents better value. And even though BMW mandates a hybrid driveline, there are still some significant choices within that framework.

By all means buy the M50 if you crave the rush of acceleration that almost 300kW can provide. And if efficiency is your altar of choice, then the plug-in 30e makes a lot of sense, too.

But even if you can afford either of those two more expensive variants, whatever you do, don’t dismiss the entry-level 20 model. At least drive it alongside the others and then make a decision based on all the facts, and not the assumption that entry-level equals the car you afford rather than the car you want.

It might be cheaper, but there’s absolutely no doubt that the 20 model is the one that shines and arguably makes the most of the opportunities BMW’s latest tech offers.

Sometimes less really is more.

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

It might be badged an X3, but this is no small vehicle. In fact, it’s bigger than the original BMW X5 (which set the tone for this entire market segment) with a length of 4755mm (4667mm for the first X5) and a width of 1920mm (1872mm). That said, it’s 25mm lower than the outgoing X3 in a move to emphasise its sportiness. Shorter it may be, but it’s also 16mm wider on the front track and 45mm wider on the rear than the outgoing model.

BMWs latest styling cues also appear in the new car, including the large, split-kidney grille that, for Australian-delivered cars, is also lit around its edges. The short overhangs that characterised the original X5 (and soon characterised this whole BMW genre) remain, and the T-graphic LED tail-lights round out the stylistic touches.

The other thing we noticed (and we’ve seen it on other cars recently) is a panoramic sunroof that doesn’t actually open.

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.

Cabin space is plentiful in the X3 with loads of room in the front, possibly thanks to the dashboard that is pulled back from you with only the twin screens and steering column offering themselves up to the driver. Even the air-vents are somewhat hidden. There’s good vision out and the seats themselves are lovely. The step into the cabin feels to be at just the right height, too; not too high, not too low.

Rear seating is good, too, although the X3 will always be better as a four seater than five thanks to the shape of the rear bench, but the glass roof opens the space up and there’s plenty of charging points and storage nooks. The sun blinds on the rear-side windows of the more expensive versions should be standard kit on every car sold in Australia.

We’ll take exception to the new gear-selector which doesn’t have a defined Park position and instead relies on applying the park-brake to engage Park. But the ambient light and contrasting cabin colours are a bit of a breath of fresh air.

There are levers in the cargo area to quickly fold the rear seats (60:40) at which point luggage space jumps from 570 litres in the mild hybrid cars to 1700 litres. The battery-pack of the 30e model means that luggage space starts at 460 litres and can be expanded to 1600 litres.

The latest version of BMW’s sometimes controversial iDrive operating system is simpler and easier to use than before and supported by a new operating system, but there’s still some familiarisation necessary. One improvement has been the addition of QuickSelect which works somewhat like the old favourites button system and gets around the need to drill into menus to access the functions you want.

A head-up display is a terrific addition, although where some displays are more tolerant of polarised sunglasses, the HUD in the BMW didn’t like mine and went dark at the most inconvenient angles.

None of the X3 variants feature a spare tyre of any sort. The 19-inch tyres on the base grade are run-flats, while everything else gets a repair kit for roadside emergencies.

If you want to tow, the good news is that all X3 variants can do so. But you will need to purchase the $2200 towing package which enables the X3 to haul a trailer weighing up to 2000kg with a maximum tow-ball down-weight of 200kg.

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.

Hybrid tech across the board is the key phrase here, with the base-model 20 xDrive fitted with a mild hybrid electric motor and battery pack that works in conjunction with the 2.0-litre, turbocharged petrol four-cylinder engine. Power is 140kW and torque 310Nm. Like most mild hybrids, the electric motor offers power regeneration during braking, a mellow (by EV standards) kick in the pants during take-off and acceleration and also acts as the car’s starter motor.

The performance flagship, the M50 xDrive taps into the same technical philosophy with a mild hybrid augmenting the turbocharged six-cylinder inline petrol engine. In this case, however, peak power is a hefty 293kW and torque maxes out at 580Nm.

The most technically adventurous X3 is the 30e xDrive which uses plug-in hybrid tech to offer a claimed 91km of electric driving, about twice that offered by the original X3 PHEV it replaces. When the same 2.0-litre four-cylinder petrol as fitted to the 20 xDrive, and the electric motor are humming along together, there’s 220kW of power and 450Nm for the taking. The PHEV X3 can run in purely electric mode at up to a claimed 140km/h.

All variants use BMW’s familiar eight-speed automatic transmission and in each case, drive is sent to all four wheels on a permanent basis. Interestingly, the 30e and M50 versions package their electric motor as part of the engine-transmission combination. The 20, meanwhile, places its electric motor externally, as part of the drive-belt rotating assembly.

The M50 model has an M button that unleashes the full performance with one touch, and features an electronically locking rear differential in the interests of high-speed turn-in.

Adaptive suspension that varies the degree of damping is also part of the package on each X3 variant.

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.

As you might expect, the PHEV 30e model is the efficiency superstar of the X3 line-up with an official combined test figure of just 1.6 litres per 100km and 38 grams of CO2 per kilometre. The four-cylinder 20 xDrive is not bad for its size at 7.5L/100km (and 171g), yet the bruising six-cylinder M50 version with all that performance is not too far behind with an official figure of 8.2L/100km (187g).

The 30e PHEV features a selectable battery-saving mode as well as the option of forcing EV-only running. It features a 19.7kWh battery and BMW claims it can charge using a three-phase, 11kW socket from empty to full in two hours, 15 minutes. It does not make use of fast-chargers.

Exactly how far you’ll travel in the PHEV model will depend hugely on how and where you drive. On long, open road journeys, fuel consumption won’t be much different to the others, but with just a 50-litre fuel tank, it’s range won’t be stellar. But in urban running where the batteries are being recharged for free as you brake, the difference will be significant. Meanwhile, with a 65-litre fuel tank in the mild hybrid grades, the theoretical range (based on the official fuel number) is 865km and 765km for the 20 and M50 respectively.

While BMW recommends premium fuel for maximum efficiency, it also says that each X3 variant will not be harmed by the use of standard ULP if that’s all you can get hold of.

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.

Big heavy SUVS like this one haven’t always been too dainty on their feet. The extra bulk and height mean suspension has to be firmer, the big wheels and subsequent loss of tyre sidewall depth plays against ride quality and before you know it, the compromises have piled up and the driving experience has gone to hell.

This time, however, BMW’s claim that the X3 was designed from the start as an SUV and not converted from a sedan platform seems to hold water. There’s an overall greater sense of cohesion in the way the car steers and flows through corners and faster bends. The steering feel and feedback are a big part of that, too, and the whole seems at least as great as its parts.

The M50 is, predictably, a rocket with loads of accessible acceleration and a great noise while you’re enjoying it. That said, the 21-inch wheels and tyres don’t do anything for ride quality, but it remains an entertaining performance car in a familiar, ICE kind of way.

The plug-in is also perky with its 220kW on tap, but it’s less old-school and more techy. And while you can’t pick the point at which ICE hands over to electric and vice-versa, sensitive drivers will absolutely know that there’s a big dollop of electrical assistance when your right foot starts asking the tough questions. It definitely feels more overtly hybrid, though that shouldn’t be any kind of surprise, purely because that’s precisely the case.

Which brings us to the 20 entry-level grade. And while it’s going to be a controversial statement, this emerges as the most cohesive, rounded variant of the new X3. There’s something in the way the fizzy, bubbly (but very smooth) 2.0-litre four-cylinder provides more than enough urge, but never threatens to dominate the dynamics.

With less weight over the front wheels than the M50, and less weight overall than the PHEV, the 20 corners flatter, steers more intuitively and is simply more fun more of the time. Even on the optional 20-inch tyres, it rides better than the others, too, and might even be better again with the standard 19s other than the fact that those are run flats and we didn’t get try them.

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.

BMW’s warranty on the X3 is the company’s usual five-year/unlimited kilometre deal. But in this case, there’s also a six-year/100,000km warranty on the high-voltage battery.

Also typical for BMW is the service interval which is not a set time or distance and instead is determined by how the car has been used. It’s called condition-based servicing and it’s nothing new at BMW.

There’s also capped-price servicing available. For the X3, the five-year/80,000km service package is $2475.

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.
