Pros & Cons

  1. ProPhone integration; spacious interior; five-year warranty.

  2. ConTyre noise.

  3. The Pick: 2018 Mitsubishi ASX LS ADAS (2WD) 4D Wagon

What stands out?

Expand Section

The ASX has more space inside than most small SUVs and drives nicely on country roads, with a comfortable ride, good steering and plenty of power – especially in diesel form. Mitsubishi’s smallest SUV works very well with smartphones and comes with a five-year warranty. All-wheel drive is available, as is auto braking.

What might bug me?

Expand Section

That you can’t play music directly from Compact Disc – there is no CD player.

Driving at 80km/h on the space saver spare until you can fix your full-sized flat tyre.

What body styles are there?

Expand Section

Five-door SUV-type wagon only.

Petrol-powered versions of the ASX drive only the front wheels, while diesel models drive all four wheels.

The ASX is classified as a small SUV, lower priced.

What features does every Mitsubishi ASX have?

Expand Section

Cruise control, a reversing camera and rear parking sensors. Air-conditioning that maintains a set temperature.

A leather-wrapped steering wheel, adjustable for reach and height, that carries buttons for operating the cruise control, the sound system and your phone. Height adjustment for the driver’s seat.

A sound system with AM/FM and digital (DAB) radio receivers, USB input, Bluetooth connectivity for phone calls and audio streaming (with voice control), and at least four speakers, controllable from a 7.0-inch colour touchscreen.

Support for Apple CarPlay and Android Auto (via Mitsubishi’s Smartphone Link Display). Plug in a compatible smartphone and you can use some apps from the car’s central touchscreen – among them, navigation apps.

Eighteen-inch wheels made from an aluminium alloy (which look good without plastic trim). A space-saver spare wheel.

Daytime running lamps, illuminated by very long-lived LEDs. Roof rails, which make it easier to fit rooftop luggage systems.

Hill-start assist, which controls the brakes automatically to help you take off from rest on uphill slopes.

Seven airbags. Anti-lock brakes, and electronic stability control - which can help control a skidding car. (For the placement of airbags, and more on Mitsubishi ASX safety features, please open the Safety section below.)

The ASX is covered by a five-year, 100,000km warranty.

Which engine uses least fuel, and why wouldn't I choose it?

Expand Section

The 2.2-litre turbocharged diesel, which uses 6.0 litres/100km in official tests (city and country combined), is the most fuel-efficient engine in an ASX. It also feels more powerful than the alternative petrol engine in everyday driving.

One reason you might not choose the diesel is that you want to pay less for the car, and don’t need all-wheel drive. (Both ASX diesel models have AWD and automatic transmission.)

The diesels also cost more to service. And you need to get them up near highway speeds for at least a 20-minute stretch every couple of weeks to clear the particulate filter in the exhaust, so they are not suited to constant short trips around town.

The 2.0-litre petrol engine uses about 25 per cent more fuel than the diesel.

That petrol engine comes with a five-speed manual gearbox or a continuously variable (CVT) automatic, which brings better performance and fuel economy than most conventional autos.

The diesel engine drives through a six-speed conventional auto.

(Power outputs and all other Mitsubishi ASX specifications are available from the Cars Covered menu, under the main image on this page.)

What key features do I get if I spend more?

Expand Section

The ASX comes in three petrol versions, each front-wheel drive, and two diesel versions, both all-wheel drive. The most expensive petrol ASX costs about as much as the less expensive diesel.

So, one pair of features you can get if you spend more is a diesel engine and AWD.

Having chosen petrol front-drive or diesel AWD, you can think about other features.

In petrol form you can spend as little as possible and have an ASX LS. That will get you cloth seat trim, manual transmission, and the other features shared by every ASX. Auto transmission is an extra-cost option.

For about $1500 more than an ASX LS auto you can have an LS ADAS, which comes standard as an auto and adds Mitsubishi’s Advanced Driver Assist Systems. These comprise autonomous emergency braking (Mitsubishi calls it Forward Collision Mitigation), and Lane-departure warning. In addition, your windscreen wipers operate automatically when it rains. And your headlights turn on automatically at night or in tunnels, and switch themselves from high to low beam when required.

For a lot more again you can have an ASX XLS, which sticks with auto transmission as standard and adds luxury. You get part-leather seats, heated in front and power-adjustable for the driver. Smart key entry lets you unlock the car by pressing a button on the door handle when the key is nearby (for example, in a pocket or bag), and you can also start the engine by pressing a button. A big sunroof stretches over the front and rear seats. And you get all the added features of the LS ADAS: auto braking, lane departure warning, auto-on and auto-dipping headlamps, and auto wipers.

In diesel form you can have an ASX LS or an ASX XLS, each with auto transmission and AWD standard. In other respects, the LS and XLS diesels match the features of the LS and XLS petrols.

Does any upgrade have a down side?

Expand Section

The diesel engine costs more to service. And a diesel ASX weighs a lot more than its petrol counterpart – we’re talking 175kg, or more than two adult passengers.

White is the only standard colour; all other colours cost extra.

How comfortable is the ASX?

Expand Section

The controls and displays in the ASX are logically laid out, from the circular speedo and tachometer to the buttons on the steering wheel for phone and audio functions. A trio of knobs makes it easy to adjust air flow.

Up front, the seats are comfy in city driving but they don’t have much lateral support, which means more bracing with your legs if you’re on a twisting road in the country.

While wind noise is kept at bay, noise from the tyres can be testing on country roads or at freeway speeds. The diesel engine clatters a bit, too. However, Mitsubishi says that cars arriving from September 2017, for the 2018 model year, are a bit quieter than those that preceded them (different materials are used for sound insulation).

The petrol engine, which is more popular than the diesel, feels lethargic initially but builds pace enthusiastically once the car gets moving.

The ASX does a good job of soaking up bumps at open-road speeds. Around town it is less subtle in the way it deals with surface imperfections.

What about safety in an ASX?

Expand Section

Every ASX has anti-lock brakes, stability control, seven airbags, a reversing camera, rear parking sensors, and LED daytime running lights (which make it easier for other drivers to see you).

There are two airbags in front of the driver and front passenger; one outside each front seat to protect you at chest level from side impacts; a curtain airbag stretching down each side of the car at head level to protect passengers front and rear from side impacts; and finally an airbag to protect the driver’s knees.

In addition, ASX LS ADAS and ASX XLS models bring you auto emergency braking, lane-departure warning, and auto headlights and windscreen wipers.

The auto braking on an ASX accepts signals from radar and camera sensors. Mitsubishi says it is effective at speeds up to 80km/h. (It also responds to pedestrians at speeds up to 65km/h.)

If it detects a hazard ahead (typically another car that has slowed suddenly), it will intervene in three stages. First, it will sound a warning. If you ignore the warning, it will brake automatically at part pressure. If you ignore that and a collision appears imminent, it will initiate a full-pressure emergency stop.

The Lane departure warning uses a camera to monitor road markings. Should you be about to drift into an adjacent lane on the highway without indicating – perhaps from distraction or fatigue – it will trigger an audio-visual warning.

The Australasian New Car Assessment Program (ANCAP) has rated the ASX’s safety at its maximum five stars, most recently in November 2016.

I like driving - will I enjoy this car?

Expand Section

The two engines available in the ASX deliver respectable performance without being exciting. The petrol engine is hamstrung in manual gearbox form by having only five ratios, which don’t always allow you to work it at its optimal speed. The CVT auto does a better job of maximising the propulsion available.

The diesel has more urge in everyday driving and the six-speed conventional auto shifts decisively, ensuring good forward progress.

The ASX is predictable through bends but leans significantly when cornering quickly, which sets up more dramatic movement from the body if you are faced immediately with a turn to the opposite side. Steering is light and accurate. You may feel some annoying kickback through the wheel if you hit bumps in the middle of a corner.

Overall, though, the ASX inspires confidence on country roads and freeways. Tyres grip well and the body settles quickly after bumps.

All-wheel drive versions of the ASX are light-duty off-roaders designed predominantly for on-road use: think snowy or muddy roads and easy tracks and trails. If you are planning to go off-road, remember that if you puncture a tyre you have only the skinny space-saver spare to fall back on.

How is life in the rear seats?

Expand Section

Small SUVs are not designed to transport lots of children, but the ASX has more rear-seat space than most, with good head and leg room that makes it viable as a family chariot. Dedicated vents feed cooling or heating to the rear passengers.

There’s a hump on the centre of the floor, but the rear seat base is relatively flat, making it fairly comfortable for the person in the middle.

That centre seatbelt can be retracted into the side of the inner roof, allowing the seats to be folded more easily. However, if you do that, it must be fastened with two separate buckles.

How is it for carrying stuff?

Expand Section

The boot is relatively broad, with a wide opening that sits high off the ground, so there’s no need to bend over to lift things out. A 60/40 split-fold rear seatback improves loading flexibility.

When folded, the seatbacks are on a slight angle but still create a long load area that will easily accommodate a bicycle.

Pockets in the front doors will cater for a large bottle and other odds and ends. But the centre console’s main open storage is in the twin cupholders. There is a covered binnacle under the central arm rest.

Petrol-powered models can tow 1300kg, while those powered by the diesel engine are rated at 1400kg. That is good for a small SUV.

Where is the Mitsubishi ASX made?

Expand Section

All models of the Mitsubishi ASX are produced in Japan.

What might I miss that similar cars have?

Expand Section

Possibly a CD player, which you can still get in a Subaru XV or Toyota C-HR, for example.

Satellite navigation that does not depend on your phone, available in a Subaru XV, Toyota C-HR, or Mazda CX-3, for example.

Active cruise control, which can slow you to follow cars ahead on the highway, resuming your preset cruising speed when the way is clear. This is standard on a Toyota C-HR, for example.

Rear-facing driver assistance, such as blind-spot monitoring (which warns you of cars lurking near your rear corners) and rear cross-traffic alert (which helps you back out of parking spaces, by looking either side for approaching vehicles). This too is standard on a Toyota C-HR, and available on the Mazda CX-3, for example.

Other small SUVs you might consider include the Suzuki Vitara, Honda HR-V, Nissan Qashqai, and Holden Trax.

Are there plans to update the ASX soon?

Expand Section

The current ASX arrived in 2010 and received a significant update in 2012. In June 2015 the wheel size was increased an inch to 18 inches and digital radio reception was added. In November 2016, a very minor facelift brought fresh nose styling, revised interior trim, and adjustments to touchscreen menus.

In September 2017 the ASX received a more significant facelift, this time with styling tweaks front and rear (and inside). Support for Apple CarPlay and Android Auto was added to all versions, and Mitsubishi’s ADAS driver-assistance suite, which includes auto braking, was made available. The CD player was dropped, as was satellite navigation.

An all-new ASX is under development, but its arrival date is uncertain – and may be as late as 2020.

I like this car, but I can’t choose which version. Can you help?

Expand Section

We like the ASX LS ADAS. The standard CVT auto does a good job, while the LS with petrol propulsion can be good buying. And the ADAS driver assistance suite may help you avoid the sort of in-traffic incident that can ruin your day.
