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.

Mitsubishi ASX (2010): At A Glance

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.

Full specifications

The ASX is offered in various trims, but even basic versions get alloy wheels, air conditioning and electric door mirrors. Choose a mid-spec ASX in ‘3’ trim and you’ll get (almost) everything you’ll ever need, with cruise control, rear privacy glass, keyless start plus automatic headlights and auto windscreen wipers. 

Regardless of which spec you choose, there's no hiding the fact that the interior lacks any sort of premium feel. The dark and shiny plastics, while hardwearing, feel low rent and scratchy, while the cheap switches and dials are a long way from the quality found in a Kia or Nissan.

That said, everything is bolted together well enough, which provides confidence that the ASX will survive everyday usage, without anything rattling loose. However, crossover interiors have moved on considerably in terms of quality since the ASX was launched in 2010 and it shows.

The interior is large and comfortable though and has enough head and shoulder room for four large adults. The cloth seats in base-spec trim provide lots of support and higher spec cars get leather trim, which provides more long distance comfort owing to the deeper cushioning. 

The driver's seat gets height adjustment and multi-adjustable steering wheel. There's an adjustable centre arm rest up front too, while the rear seats split 60/40 and can be folded away to provide a flat load space. 

The 442 litre boot isn't as large as the 500+ litre loads paces found in the Tucson or Ateca, but the low floor makes it easy to slide heavy items into the back of the Mitsubishi. The boot floor doesn't have a load lip either, which again makes the ASX an easy car to load/unload.

Standard Equipment (from 2013):

Models in 2 trim come with 16-inch alloy wheels, electrically foldable door mirrors, rear fog lights, hill start assist, Bluetooth, air conditioning plus electric front and rear windows

3 trim adds privacy glass, chrome exterior details, keyless entry and start, front fog lights, rear parking sensors, auto lights, auto wipers, climate control, heated front seats and cruise control.

4 trim gets panoramic glass roof, leather upholstery, powered adjustment for driver's seat, electrically adjustable driver's seat, DAB radio, navigation, rear-view camera, roof rails, front skid plates, xenon headlights along with electric, heated and folding mirrors with indicators.

What's the Mitsubishi ASX (2010) like to drive?

The ASX was launched in 2010 with two engine choices - one petrol and one diesel. The 1.8 diesel with 150PS provides the best performance and economy.

Variable valve timing allows it to trickle down to 800rpm, and it slowly accelerates without protest from 1000rpm, even up inclines. However peak torque of 300Nm comes in quite strongly at 2000rpm.

The 1.6 petrol with 115PS works fine in town, but struggles with only 154Nm. It's not turbocharged and as a result feels breathless when pushing to join a busy motorway or leave a narrow junction. Only those who are set on buying an ASX, but don't cover enough miles to justify the diesel, will want to opt for the petrol, which is also limited to two-wheel drive only.

In 2013 Mitsubishi expanded the engine line-up with the addition of the 150PS 2.2-litre chain cam diesel. The 2.2 unit produces more torque - 360Nm from 1500rpm - and is paired with a six-speed torque converter automatic transmission. It's the only automatic in ASX range, with the 1.6-litre petrol and 1.8-litre diesel linked to a respective five-speed and six-speed manual gearbox. 

All of the engines in the ASX line-up are strong Real MPG performers. As a result the 1.6 petrol should exceed 40mpg, while the 1.8 diesel should surpass 50mpg. The 2.2 diesel returns 48mpg in the hands of Real MPG drivers, which isn't bad when you consider its limited to an automatic transmissions and four-wheel drive only.  

Big, sensible 215/60 R17 tyres give decent ride quality and help absorb road humps and potholes. the steering is a little slow compared to the SEAT Ateca, but the ASX is easy enough to control. The 1.8 diesel can be specified with two-wheel or four-wheel drive, with the latter providing impressive performance in snowy and icy road conditions. 

Engine MPG 0-62 CO2
1.6 47–49 mpg 11.4 s 135–139 g/km
1.6 D 61 mpg 11.2 s 119 g/km
1.6 D 4WD 57 mpg 11.5 s 132 g/km
1.8 D 55 mpg 10.2 s 134 g/km
1.8 D 4WD 54 mpg 10.6 s 136–138 g/km
2.2 D 4WD Automatic 49 mpg 10.8 s 152–153 g/km

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.
