Mazda CX-5 vs Mercedes-Benz GLA250

What's the difference?

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

My wonderful wife, who is not really into this kind of car, admitted to me in a quiet voice that she really liked the GLA45 as long as it was in Sport + mode. And I have to agree. While I'm very fond of the ridiculous Audi RSQ3 (that turbo five-cylinder sounds amazing), I think I'd stump up the extra for the GLA.

Importantly, it can be comfortable, it can be quiet and it's a better fit for most humans than the A or CLA. It is getting on a bit and could do with a further clean-out of the poor ergonomics, but in what is likely its final year on sale, it's still a belter.

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 GLA45 isn't a looker, but then, none of the GLAs are. There's a certain blobbiness to it. A bit of Teletubby mixed with...um, another Teletubby. It's not ugly, it's just not particularly attractive. The 20-inch wheels do much to lift the appearance and negate the effect of the raised ride height compared to the A45/CLA45.

The body kit stops just short of lairy, which is heartening. So if you want to stand out, venture out into the aftermarket world.

Inside was a mild surprise. The last time I drove a CLA 45 I used the word "gaudy". While the GLA isn't amazingly better, the texture of the Alcantara replacing the brushed metal-look plastic, or the carbon of the option pack, was much more pleasant. The brightwork in the cabin is still a bit odd looking, and it's still overcooked with its red detailing, but it is an otherwise beautifully built and well-detailed interior.

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.

The front seats are utterly brilliant and feel as good as they look. On first acquaintance they may feel under-padded, but once you've adjusted them to your liking, you never want to leave. The AMG cars also feature one vast improvement over a normal GLA - the ergonomic disaster of a column-mounted shifter is removed, with a console-mounted shifter added where a small cubby once lived. It's so much better, although the Park button is oddly difficult to press.

When luxuriating in those snug front seats, you'll have access to two cupholders and door-mounted bottle holders, as well as a console bin (where the USB ports are) and a tray under the climate controls. Rear seat passengers will find legroom tight but headroom good, even with the huge sunroof.

The GLA's boot holds an entirely reasonable 421 litres, rising to 1235 when you drop both rear seats.

The GLA 45 lightens your wallet by no less than $89,211 - more than double the GLA 180 front-wheel drive, and about $5000 more than the bonkers (and ancient) RS Q3.

Packed into the GLA's kit bag are 20-inch alloy wheels, a 12-speaker stereo, dual-zone climate control, comprehensive safety gear, reversing camera, keyless entry and start, front and rear parking sensors, electric and heated front seats, sat nav, auto LED headlights, auto wipers, leather trim (some real, some not), auto parking, powered and heated folding mirrors, a massive sunroof and dynamic dampers. There's no spare tyre, just a tyre-repair kit.

The multimedia system is Mercedes' COMAND unit and it is as user-unfriendly as ever. It does, however, power a very decent stereo, and also offers Apple CarPlay and Android Auto.

Thankfully our car was bereft of both the carbon-fibre package ($990) and the aerodynamics package ($1990).

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.

AMG's fabled 2.0-litre turbo four lurks under that higher bonnet, still kicking out an improbable 280kW and 475Nm. Drive reaches the road via Merc's own seven-speed twin-clutch transmission and all four of its wheels.

All that power and grip translates to a 4.4-second dash to 100km/h for the slightly tubby (over 1600kg) GLA, but just between you and me, anything under five seconds feels scorchingly quick.

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.

The official combined-cycle figure suggests the GLA45 will consume 7.5L/100km. Obviously that figure is largely irrelevant, and not just for the usual reasons, but because you don't buy a GLA45 to potter about in. I got, uh, 12.5L/100km, so you can imagine how much I was enjoying it.

As you might expect, you'll need to feed it 98RON.

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. 

When the 45-badged cars first launched, they were something of a revelation. BMW's turbo six-cylinder fans sniffed at the 2.0-litre's staggering outputs and all-wheel-drive chassis, but this car really captured the imagination. The GLA45 might be slightly unexpected, but it's better in almost every way as a daily driver than the A or CLA.

For a start, its higher ride height seems to translate to a much better ride quality. Anything on 20-inch wheels should have an appalling ride, but the GLA45 manages to be firm yet comfortable. Put the other two in Race mode and you'll need to up your private health insurance extras to include osteo, physio and whatever "o"-ending specialist fixes your back.

The improved ride quality meant I was far happier to chuck this car around. While it doesn't have the same ultimate overall performance of the lower cars, it's far more comfortable whether you're on it or just driving around. The front seats are supportive and comfortable, and the steering is excellent.

As for the engine...well, it still farts like toddler during a moment of silence at a funeral, but you can't deny its technical brilliance and huge power outputs. I remember the CLA45's engine as being a bit highly strung. Perhaps I couldn't separate the overall high-strung nature of the car from the engine, but I felt the same engine in this car wasn't as jumpy.

The way it propels this car into triple figures is tremendous fun. It's not as charismatic as the Audi five-cylinder, perhaps, but that doesn't matter in the end - it's properly fast, attached to a better chassis and offers a cabin with a driving position fit for humans.

The GLA comes with nine airbags (including driver's knee), blind-spot sensors, lane-departure warning, lane-keep assist, forward-collision warning and mitigation and driver-attention detection.

The GLA does not have its own ANCAP rating, but the A-Class on which it is so heavily-based scored five stars in 2013.

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.

The Mercedes standard warranty is three years/unlimited kilometres with roadside assist to match. Service intervals are a very reasonable 12 months/20,000km.

The company also offers capped-price servicing - first service is $576 but the second and third are a whopping $1152 each. Three years will set you back $2880.
