Mitsubishi ASX (2010 – 2021) Review

Mitsubishi ASX (2010 – 2021) At A Glance


+Well-equipped as standard. Impressive Real MPG scores. Plenty of room for five plus luggage. Five-star Euro NCAP rating.

-Disappointing interior quality. Nosy diesel engines. 1.6-litre petrol lacks pace.

Insurance Groups are between 13–23
On average it achieves 84% of the official MPG figure

The Mitsubishi ASX is a crossover that provides decent value and everyday practicality, with a spacious interior and good amounts of kit fitted as standard. It also scores consistently high scores for Real MPG, which means it should get close to its claimed fuel economy. Not something you can say of many cars...

That said, the ASX does have its problems. It's not as plush or as refined as competition like the Hyundai Tucson or SEAT Ateca - and the interior feels rather cheap. However, the ASX is robust and usefully large. It is also available with four-wheel drive, which makes it an appealing crossover for those who want a no-nonsense, rural run-around. 

At launch, the ASX was offered with 1.6 petrol and 1.8 diesel engines. Both score highly for real world fuel economy, which means an average driver should easily exceed 40mpg for the petrol and 50mpg for the diesel. That said, the 1.6 petrol engine isn’t particularly powerful, with poor refinement and lethargic performance through all of the gears. 

The ASX works best with diesel and while the 1.8-litre unit has 150PS, it's noisy, with lots of clatter. But pulls strongly from the low gears thanks to 300Nm of torque. In 2013 Mitsubishi added the 150PS 2.2-litre diesel to the range, with more torque and a six-speed torque converter automatic transmission. Like all of the other engines, the 2.2 scores well for Real MPG, which means it will return 48mpg. 

Both diesels are available with two-wheel or four-wheel drive, with the latter making the ASX well-suited to rural conditions. Indeed, with winter tyres fitted, the ASX performs strongly in the snow, with mountains of grip and well-weighted steering that makes short work of treacherous B roads or muddy farm tracks.

The ASX isn't as good to drive as some of its rivals on the motorways or A roads though. All of the diesel engines are loud and there are high levels of road and wind noise above 50mph. The ride is comfortable though while the interior is hardwearing and large enough for four adults. There is also a large 442-litre boot.

With high levels of standard equipment and a five-year/62,500 mile warranty offered as standard, the compact and capable Mitsubishi has plenty to offer buyers in need of a practical crossover with affordable fuel costs. Not everyone will be taken by its lack of refinement or luxury, but if you prioritise value over plush interiors, then the ASX will be one for the shortlist.

Should I get rid of my Mitsubishi?
"Given Mitsubishi Motors announcement that they are not going to supply any new models to Europe and UK and are withdrawing from this market, should I hold onto my three year old Mitsubishi ASX or would it be prudent to move it on?"
The brand isn't withdrawing from the UK entirely. As we understand it, it will continue to sell its existing range of vehicles for the foreseeable future and then, after that, provide aftersales support. The cars will still be sold elsewhere so parts should be relatively easy to source. It's a bit different to a brand like Saab or MG Rover, for example - both of which existed one day and were gone the next.

Do I need to tell my insurer if I fit run-flat tyres?
"I'd like to fit run-flat tyres to Mitsubishi ASX. The standard tyres size is 225/55/18 but run-flats don't come in that size. My local tyre dealer recommends 245/45/18 which are available as run-flats. Would I need to tell my insurance company?"
No, you do not need to inform your insurer. As long as the tyres are legal and meet OE standards then you are fine.

Buying a small to medium sized crossover, which would you recommend?
"I'm looking to sell my wife's Mitsubishi ASX 2 1.6, which we've had from new for five years now. I've been considering leasing, from new, either the Seat Ateca 1.0 TSI SE or the Suzuki Vitara 1.6 SZ-T 2WD. Which of these would you recommend?"
If it's between these two, then the Ateca 1.0 TSI. But if it were between the Ateca 1.4 TSI and the Vitara 1.4 T Boosterjet, I'd go for the Vitara.
